Hello all, I’m attempting to emulate a "Smack" of Comb Jelly fish- because they are cool * QED.

To that end i’m attempting to animate the shape of several spheres (using jit.gl.multiple) and have them be semi transparent with color animations along their edges.

My thought is to warp the a sphere shape using jit.gl.mesh as is displayed in this video. https://www.youtube.com/watch?v=uzQOiwMkESU by the amazing Andrew.

As you can see a mesh is being fed by a gridshape. That obviously works. 

The issue arrises when i try to create several of the forms using jit.gl.multiple. I’m not seeing any shapes when I add a jit.gl.multiple.  Please see attached code.

Any suggestions?

looks like jit.gl.multiple is drawing to the wrong context:

YES!!! Thank you. That name, target, context is a bear.

Thanks a bunch Matteo! I'm hoping to apply a transparent layer to the spheres you fixed, would you suggest jit.gl.material or jit.gl.pbr. or something else?  I'm hoping to wrap these shapes in some blinking noise like this. https://cycling74.com/forums/blend-mode-alpha-jit-gl-texture
See rob's solution. Does that seem like a reasonably elegant approach?

Hey Enki, you should be able to just apply a texture to the spheres like this:

I'm having issues with jit.gl.videoplane automatically scaling a transparent png file to the native resolution of the jit.world.

Eg. - I'm reading a file of 722x638 resolution, but it doesn't render at that size; it is automatically rendered significantly bigger, and I have to try to manually scale it down (scale is originally shown as 1. 1. 1., but the image appears much larger).

I've looked at transform reset and preserve aspect ratio but with no joy.

I'm having issues with jit.gl.videoplane automatically scaling a transparent png file to the native resolution of the jit.world.
Eg. 

jit-gl-videoplane-autoscaling-to-canvas-resolution

Try scaling the videoplane according to the aspect ratio of the image:

I've made a patch based on yours illustrating my issues.

So, in my case I need my jit.world to be 3840x2160, and I'm just trying to show a movie or PNG file which is 722x638 at the PNG or movies orignal size (i.e. it will only take up a fraction of the screen). Using your patch I still get the original problem.

When I use jit.matrix and jit.matrixinfo it shows that it's 782x638, but at some point my image is getting scaled up to the resolutions of my jit.world.
I've played around with pretty much every setting of the videoplane but am really stuck with this.

Ah, ok, I didn't get the final output was supposed to be of a different size. 
Then I guess you'll have to consider, together with the aspect ratio, also the ratio between the vertical dimension of your picture and the vertical dimension of the rendering window:

From what I understand you want to display a smaller image over a big jit.world.
Quick suggestion: try to use jit.gl.cornerpin to resize and dispose your png. (And note that size is not an attribute of jit.movie)

Hi Riccardo - Thanks for your reply. I'm curious: how would jit.gl.cornerpin be different from using scale and position attributes of jit.gl.videoplane?

jit.gl.cornerpin is undoubtedly an excellent tool for placing/resizing/distorting an image in the gl context and something worth exploring that can get the job done. 
For your needs, maybe it's a bit overkill because the definition of the positioning and scaling is done by providing the spatial coordinates of the 4 corners; therefore, if you need exact scaling, you still have to go through ratios and stuff. Besides, it's a bit slower than a "flat" videoplane because it compensates for affine transformation issues behind the curtains.
(see here for more details: https://stackoverflow.com/questions/12414708/correct-glsl-affine-texture-mapping)

HI,  surely you can get the same results by scaling and positioning a videoplane, but I remember that some years ago I had a similar problem: In a show I had to project a large series of slides (all with different sizes and orientation, without changing its size ) over some SD movies (in those days it was the highest resolution ;-) and jit.gl.cornerpin @preserve aspect 1 saved my day.....

Afterwards I'm certainly not able to go so deeply into openGl as Matteo (btw Ciao Matteo!)


Thanks both for your explanations - I was sort of fudging it in a laborious way before.
@ Matteo - what you did there works great, and I've incorporated a bit a querying of resolutions to make it automatic.
It's made it clearer what the relationship between videoplane, jit.world and jit.movie is - will come in handy for sure.

Hi,
I was playing with this RTSP server:
https://github.com/aler9/rtsp-simple-server#from-a-webcam

The server itself works fine, I can load video to stream and VLC opens it without an issue.
On the max path, I can load the RTSP demo https://www.wowza.com/developer/rtsp-stream-test and it works fine, however, once I try to load the video from my local RTSP server, Max stops responding. 
This happens every time I try to load my RTSP stream. I have tried changing localhost to 127.0.0.1 or my computer's local IP address but stops responding every time...

For me, this feels like a bug on the jit.movie that stops the whole Max to work!

Can anyone test this out and confirm? Or maybe I am missing something?

jit-movie-crash-max-8-5-2-on-loading-rtsp*-video

Hi,
i have an issue with jit.movie with rtsp too
it seems jit.movie is not working well with rtsp.
 i have an ip camera. i can open its stream with vlc (rtsp://192.168.2.20:554/stream1) 
but with jit.movie nothing happen (error loading file)


unlikely we'll get this working in any recent update, so my recommendation would be exploring solutions using OBS and piping its output back to Jitter using Syphon/Spout (possibly using this Node project as a basis for controlling the OBS rtsp streaming remotely from Max).

If this is of interest, I may be able to find time to explore expanding that node project for this task.

I was thinking about trying to make an external with webrtc sdk client, that could output jit.gl.
I have successfully run webrtc server from node and could connect 2 web clients together, I know that there are projects that converts webrtc to rtsp. This could be a possibility establish real time streams without obs.
But i need more understanding of jit.gl externals programming...
OBS is great solution tho, obs window (app) capture and streaming content to virtual camera is one of the way to go, I am not sure how to stream syphon out from OBS (getting syphon is clear). Or what kind of solution do you suggest? Any tutorials for proper setup?
Sadly, there are no solution in syphon browser direct stream.

Thanks Rob!

sigh, I forgot Syphon output from OBS isn't supported directly, though it is possible. You must first install NDI and the OBS NDI output plugin (this link also contains links for the NDI lib). Then install the free and awesome NDISyphon app. From OBS Tools menu select NDI Output Settings and enable the main output. Now in NDISyphon you should see the OBS stream as a source, enable it and you can receive the stream in Jitter. phew.

This link walks the process step-by-step for a different Syphon client, may be helpful

Thanks for sharing, this is very elegant solution, if I can get rtsp or webrtc or any other than screen capture method, into the OBS, then this solutions looks very elegant and hopefully stable. Also your node project to control obs remotely looks very interesting! I would be interested in contributing and you want, or maybe fork into my own projects.

Lets hope Cycling will brings someday good live stream feeds into Max without additional software like obs.

Does somebody know, if the [vr] Package from Graham Wakefield works with the Oculus Quest 2 ?
Planing to buy a VR device. The  Oculus Quest 2 seems to be a nice one ;-)

Hello,
Does somebody know, if the [vr] Package from Graham Wakefield works with the Oculus Quest 2 ?
Planing to buy a VR device. The  Oculus

graham-wakefield-vr-package-works-for-oculus-quest-2

The [vr] package supports both Oculus API (LibOVR  SDK version 1.1.15) and SteamVR API (OpenVR SDK). If the Quest 2 works with either of those, it should work with [vr].  

However there's a chance we might need to update the SDK versions for the [vr] package, as they haven't been updated for a few years now. 

From a quick google, it looks like Quest 2 support was added to LibOVR in SDK version 23, which is quite a big jump forward. That means it might need a bit more work to update the [vr] package, I don't know how much their API has changed. 

But if Quest 2 can work with SteamVR, then it might work already right now.  

Hello Graham,
Thanks for answering in person in this short time :-)
Will borrow a Quest 2 and test it out. Perhaps it works out of the box. 
Will post my experience.
All the best,
HH


I've tried out quest 2 with MAX /VR package with the cable (oculus link) and worked well. In order to connect to Quest 2 via cable you need to install the desktop Oculus App. I still need to try the wirelles connection.

hello sandroid,
thank you very much for the information !
have you also tryed to use the quest 2 controller ?
will test the wifi connection next week.
all the best,
HH


Any update on this topic ?
did someone managed to use a quest 2 wireless with Max VR ?
what about the controllers ?
Is there a way to get hands tracking in Max ?

Hey everyone.

I'm very much interested in this topic as well! Thank you Sandroid for letting us now that the Quest 2 works well with the package, this is great news. Have you tried the wireless connection as well?


Ive just tested a Quest2 with Max VR : it works very well with airLink and Virtual Destop.
Much more stable and reliable than a Vive Pro Wireless, for a fraction of the price... it's amazing !

With AirLink : Max VR uses the Oculus driver ; it works just fine, I could use the controllers.

With Virtual Destop : you have more options to adjust streaming quality, and it allows you to run steamVR applications ; Max VR will run using steamVR drivers.
AND : there's a very cool option : you can use hand tracking : hands are seen as controllers (pinch & grab emulate trigger and button)
You can't get all hand's joints & fingers positions, but at least it's possible to use hands with Max.
I guess it *should* be possible to get hands data, as it seem to work in Unity (probably using developer mode ...)
Hands tracking on the Quest2 has smaller latency and wider field of view than using a leapMotion, but hands occlusion is a bit less permissive.

my conclusion after 2 days of test : the Quest2 seems to be a very good choice to explore VR in Max
inside-out tracking + image quality + low latency + wireless +  attractive price = :-)

I would really love to find a way to get all hands tracking data into Max ; any help would be very welcome :-)


Mathieu, thank you so much for testing, those are all great news! Sounds really interesting indeed. Having native integration without Virtual Desktop would be great, but having hand tracking is already pretty amazing. Nice, will be getting one soon!

One extra thing that I just noticed: it seems that the VR package doesn't work with GL3. I get the error: "ob3d_draw_begin: GL Error: Invalid enumeration". Any ideas?

I've got a fairly untested build of a gl3 compatible vr.mxe that you are welcome to try.

To update first install the VR package from the Package Manager, and then replace this unzipped mxe64 into the externals folder of the existing VR package.

Hey Rob, thank you so much for the file. Just tested it and it seems to work pretty well in my patch. I don't have a Oculus with me today, but in the next upcoming days I will test it properly and I will let you know.

what would you recommend if i wanted to use vr.mxo on os x? so far I couldn't detect the oculus quest 2 to connect from max. is this all windows only or any chance of getting this to work in os x?

You need oculus App running to use AirLink, so IMHO it's windows only...

Hello to this thread.
I am trying to use this with Quest 2.

The external is able to connect to the HMD and get tracking data-- as evidenced by the render preview panes updating the camera position (and showing the controller moving)

However, it isn't able to render graphics to the headset. Error messages on each frame:

vr - no texture set yet
vr - problem copying texture
vr - problem submitting texture
Tried Rob's gl3 version of the external -- no change.
If anyone has encountered this and has a fix or workaround, please let me know. Thanks!

I'm using a Quest2 with vr external without any issue, using wireless Virtual Desktop or ALVR.
(using steamVR)
If you're using Link / airLink, vr uses Oculus driver, maybe that's the culprit...

also make sure everything is using the same high performance GPU - https://support.serato.com/hc/en-us/articles/202305784-Changing-graphics-card-settings-to-use-your-dedicated-GPU-on-a-Windows-computer- 

Thanks Rob.
Got it working using the Oculus driver by adjusting settings in the NVIDIA Control panel.
Under Manager 3D settings, I switched the "global settings" from "Auto-select" to "High-performance NVIDIA processor"

Hope this can be helpful for the next person that encounters this issue.

I have tried to use the vr object with the Meta Quest 2 on a MacBook Pro with Windows 10 via Bootcamp. While I was finally able to connect via Link and QuestLink, I kept getting these error messages  with the vr helpfile:
vr: no texture set yet
vr: problem submitting texture

I'm running Max 8.5.2 set to gl2. What could be the reason for these messages? 

Im using air link on my quest 2 and the positional data is getting sent to the patch but the screen is just black.
I keep getting the error ob3d_draw_begin: GL Error: Invalid enumeration 

if anyone knows how to fix this it would be much appreciated. 

Hi, I do not know if my question should appear in this thread, or whether I should start a new topic ( please feel free to let me know or move this to another thread). 

I am trying to use a Varjo XR-3 (Hi-Res AR headset with SteamVR compatibility mode) on a Windows11 machine with Max via Graham Wakefield's  VR external (which I just downloaded via Max package manager) ... very excited to see the results! However, when I tried the help patch  I got the error: 

• Unable to init VR runtime: Shared IPC Compositor Connect Failed (306)

The device was connected and VR-INFO showed there was a steam device "steam_available 1", but SteamVR wasn't running. Might this be the reason of the error or anything I could try to make it work? Any help would be greatly appreciated.

To determine if it works with the Oculus Quest 2, you should consult the documentation, release notes, or support channels provided by the package developer, Graham Wakefield. They may have specific information on compatibility with different VR devices, including the Oculus Quest 2.

I have this patch running in Max for Live as a part of a bigger installation, where I match sound to colors on a pixel. I have been running it with videos for some years, but now I would like to integrate it with spout inputs. I have 6 of these running in my project and performance is killing my 3080 graphicscard. Is there any way to optimize the patch? I have tried Matrix out from the jit.world and now jit.asyncread without any difference.

I'm amazed by the recent advancements in gl-core and am currently exploring the possibilities of Jitter.

The PBR shaders generated internally by jit.gl.model seem to have different specifications than jit.gl.pbr. I was unable to achieve the beautiful PBR rendering shown in @material_mode 3 when re-compositing with jit.gl.mesh.

I tried to get the material dict from jit.gl.model and reapply it with jit.gl.material or jit.gl.pbr. I also attempted to reapply the shader code outputted from jit.gl.model using get_shader to jit.gl.shader, but I was not successful.

Is the process described in the title even feasible?

I believe the situation here is that gltf material format supports combined metal and roughness textures. so we must first unpack that texture before sending it to the pbr input. I believe the Roughness is stored in the Green plane, and Metalness in Blue.

I have plans to add some functionality to jit.gl.pbr to load these materials directly from the GLTF files for some future update, so thanks for exploring this space sharing your experiences.

Can anyone tell me why my jit.render is no longer rendering a sphere as it was before. This is an edit on a delicious max tutorial that was working perfectly. Im unsure what ive done but its no longer rendering. Apologies for the messy code.
 Thanks for any help!

Can anyone tell me why my jit.render is no longer rendering a sphere as it was before. 

jit-world-no-longer-rendering-sphere

Hi Kieran,

The problem with your patch is that there's no object drawing the sphere. You're using a jit.gl.gridshape (that should draw it), but with the attribute @matrixoutput 2; this makes jit.gl.gridshape stop drawing the sphere and output the geometry as a matrix. 
This technique is used to apply further manipulation to the geometry.
The matrix then is plugged into a zl object, which implements many different functions, but 3D rendering is not one of them. 
Look at this edit of the patch:

I plugged the matrix into a jit.gl.mesh object that draws the sphere again. I also attached a jit.gl.pbr object to shade the mesh.

Thanks a lot!! I knew it would be something simple. Unfortunately as I am running max 7 at the moment the jit.gl.pbr object didnt work but this has resolved my issue and got me back to a point where I can work forward from! Thanks! 


Great to hear it worked! If jit.gl.pbr isn't available, switch to jit.gl.material; it will do the job

Wow, crazy fx. One last question. Where is this rendering to? i want to make it fullscreen for projecting and also get rid of the bar at the top with the minimize and x. 


To answer your first question, the scene is rendered to a texture via the object jit.gl.node. Try to connect it to a jit.pwindow object, and you'll see the rendered image. Then, the texture (after further manipulation) is plugged into a jit.gl.videoplane, that displays it on screen (inside the jit.world window). I'd suggest checking out the help files of these objects to understand better how they work

To make the window fullscreen, you have three possibilities:
1) click on the window and then press "ESC" to enter and exit fullscreen mode
2) send to jit.world the message "fullscreen 1", to enter full screen and "fullscreen 0" to exit.
3) set manually the attributes of  jit.world, in particular 
- "border 0" to remove the top bar
- "floating 1", to keep the window always on top
- "rect x0 y0 x1 y1" to decide the extent and positioning of the window;  x0 y0 is the position (in pixels) of the top-left corner of the window, and x1 y1 s the position of the bottom-right one

"1) click on the window and then press "ESC" to enter and exit fullscreen mode"

No way, when was this implemented? No more key into sel32 into toggle into fullsreen$1! 

Mucho gracias, I'm understanding more and more each day. Thanks again.

hopefully write the code myself someday :)


See the comments here: https://cycling74.com/project/fragile-territories/

Analog control signals are relatively easily generated in Max/MSP and sent out through a suitable audio interface (eg. MOTU) or a dedicated DC interface.

Next thing I'd like to figure out is how to convert vector/opengl graphics to ILDA. 

Think about safety when working with lasers.


yes i saw this project! it's DREAMY.
https://cycling74.com/project/fragile-territories/

it is sound based? but it is already very "graphically", so it only sent the sound to multiple channels to 4 laser projectors? i use to tried sound card method but my m-audio410 only gives 0~24v, laser projectors requires -24~24V, that's the problem. anyway, do i need to modify the circuit in MOTU? if not then it is very good news! i hope Robert Henke can share some patch, just for the sound control...


It's highly unlikely that your m-audio outputs 0-24V. A standard audio signal oscillates from + to - (AC) and 24V would crazy loud for a line output. Around 5V would be more logical. My MOTU 828mk2 outputs +/-4.5V and my UltraLite mk3 +/-4.1V.

If your laser needs +/-24V then you will need an opamp to get the signal into that range. I recently worked with +/-5V lasers so it didn't need amplification.

Important is that the audio interface has to be able to output DC signals. Most filter out DC as a protection. MOTU is one of the exceptions that allow DC and thus can be used for analog control signals.

See this thread too: https://cycling74.com/forums/controlling-analog-synths-from-max

About 'sound control', the point that you seem to be missing is that you use audio DSP processes to generate control signals. Is it 'sound'? In a way, but any DSP signal only becomes sound when transduced by a speaker. Before that it's just digital numbers or analog voltages that can just as well be used to control the motion of a laser scanner or the intensity of a beam. That's what's happening here. It's perhaps more helpful to see it as LFO's. If you can draw shapes in an X/Y oscilloscope you can draw them with a laser.

thanks for catching the documentation error, I'll make a note to update this.

It's a reasonable behavior, that jit.gen's output would follow the geometry of the input matrix (or at least that it can't magically expand the input). Just confused me a bit that @planecount seemed like it might do so.

Jitter Spectrogram with logarithmic display

Rob Ramirez

Happy post RNBO day everyone, I've got some details and context on what the Jitter team has cooked up for the 8.5 update.

Top of the list, GLCore (or glcore) and what it's all about. With 8.5 we've done 2 things:

Renamed the formerly beta gl3 engine to glcore

Transitioned our default graphics engine from the legacy gl2 to the modern glcore.

The reason for the renaming is to better reflect the reality that most graphics cards will support OpenGL versions beyond version 3. The engine provides support for modern core profile OpenGL at whatever version your graphics card supports.


For existing gl3 users not much has changed in functionality (other than the new juicy bits described below). However the consequences extend beyond the technology. We now have a solid foundation for continuing our engine modernization and growth, and can fully document the new behavior and features. To that end there are a handful of new examples to check out in the glcore Examples Extras patch.

For gl2 users this is a significant but hopefully seamless change. We will publish more details on how best to utilize modern graphics engines and other ins and outs, and we strongly encourage contacting support with any issues. However if you wish to revert back to gl2 simply change your Graphics Engine (gfxengine) preference back to gl2. You first might want to check out the afore mentioned glcore Examples patch to see what you're forgoing.


A new entry to our Jitter Tools suite is the jit.gl.textmult object, which allows for manipulating letters and words of text using a jit.gl.multiple like interface and highly efficient mesh rendering. As an added bonus for text lovers we’ve removed the 1024 character limit on jit.gl.text input strings.

Also included with 8.5 are some lovely new jit.gl.pass post processing effects. The atmospheric effect adds global fog and atmospheric scattering to any 3D scene with ease, and for experimenting with global illumination check out the temporal screen-space ambient occlusion (tssao-gi) and screen-space reflections (tssao-gi-ssr and ssr) effects.

Speaking of global illumination, the new jit.gl.environment object handles the loading and sharing of environment map resources for image based lighting (IBL), cubemap, and skybox rendering for supported objects. This currently includes jit.gl.pbr, jit.gl.material, and jit.gl.skybox. The object functions like jit.gl.light, where if a context has an environment attached, the supported objects will use it for rendering.

We've also added glTF PBR material support to jit.gl.model, giving much better results when rendering these model files. In the video below we see non-PBR rendering on the left, and PBR rendering on the right.

For links to the example patches mentioned (and loads more) check out the glcore Examples and Jitter Tools Extras patches, and the jit.gl.pass reference page.

Top of the list, ... 

jitter-8-5-and-glcore

Hey everyone, we've got an update for glcore included in the Jitter Tools 1.0.6 version now live in the Package Manager. This update addresses a handful of reports we've received since the release of 8.5 and is recommended for all 8.5.x glcore users.

fix move texture output when skybox enabled in same context

jit.gl.mesh - fix crash on certain adjacency draw modes

jit.gl.path - evalout equals zero drawing fix

jit.gl.text2d - fix screenmode 0 rendering with high dpi display

jit.gl.environment - reflection map edge length attribute

jit.gl.meshwarp - external input matrix for initial mesh geometry via mesh_matrix message

jit.gl.meshwarp - output_mesh_matrix message to output the mesh vertex data

Rob, congrats to you and c74 on glcore. I get the effort your team put into it. :-)
Are there C/++ examples for the updated interfacing possible HOST to/from GPU for textures, buffers, mapping between max,opencl,opengl, etc.

Unfortunately I don't have a great answer for you. The SDK has not been updated with examples for developing for glcore, and given the current state of flux in our backend graphics engine work, I don't have a good estimate for when that might change. 

That being said, both Syphon and Spout are open source and demonstrate how an external can support both legacy gl2 and modern glcore using some wrapper functions we expose in the jit.gl.draw.h header file. If you're only concerned with core profile support you can ignore these wrappers and link to the gl3 library headers instead (which may be easiest by defining GL3_VERSION=1 in your project preprocessor definitions). Additionally, the basic principles of jit.gl external development outlined in our SDK documentation still hold true.

I'm also more than happy to provide whatever insight I can for any brave explorers in this space.

Fantastic, thank you Rob and the team!

Do you have do you have any idea when TXAA / TAA is coming to Jitter!? Ref here at 16m20s https://youtu.be/S7xPbjICNsw 

I just posted the TAA pass fx here:
https://cycling74.com/forums/sharing-temporal-anti-aliasing-taa-fx-for-jit-gl-pass 

At the moment, it's quite complex to make it available as a built-in tool, but if you're interested in it, check out the patches at the link above

Thanks for the response; will check out the patches!

I am excited about the great jitter upgrade!

I'm working on some samples, so check out my twitter as well.

I have a few questions as I use it.

Will the pbr in jit.gl.model be reflected without jit.gl.pbr connected? (I loaded the glTF and it seems to reflect the pbr textures without specifically connecting jit.gl.pbr or jit.gl.material). and, I could not change pbr parameter on jit.gl.model.

Also, if the texture loaded in jit.gl.model references a multi-texture by albedo, can I use the multi-texture in jit.gl.pbr when drawing with matrixoutput or jit.gl.mesh?

Jitter's material has many inheritance relations and parameters, and jit.gl.model is very difficult due to some invisible parts, so it would be great to have contents like 1st step.

Hey Enki, you should be able to just apply a texture to the spheres like this:

Thanks both for your explanations - I was sort of fudging it in a laborious way before. @ Matteo - what you did there works great, and I've ...

Hi there. I have this patch running in Max for Live as a part of a bigger installation, where I match sound to colors on a pixel.

I believe the situation here is that gltf material format supports combined metal and roughness textures.

Mucho gracias, I'm understanding more and more each day. Thanks again.

Sorry to self promote but I've been doing this for quite some time, and I give workshops and performances around using Max and Lasers....

Thanks, appreciate it. It's a reasonable behavior, that jit.gen's output would follow the geometry of the input matrix (or at least that it ...

Actually got it working with pieces of the first patcher!
