in the spirit of the holidays, i present to you the fruits of my master's thesis labor...

This project is a jitter external which embeds the functionality of the open source Ogre3D rendering engine, and exposes it to the max environment. What this basically means is you can export models from several 3D modeling applications, with textures/materials and animations, and render them and control them in jitter using hardware buffer acceleration.

SAD TECHNICAL NOTE: This is currently intel-mac only. i apologize. porting to win and ppc is first priority and will hopefully happen before i take my holiday vacation, but please be patient if it doesn't.

The link below is a recording of a patch, which utilizes the great jit.boids3D to control 250 animated fish. The fish mesh comes with the ogre3d distribution to use in their samples.

http://www.youtube.com/watch?v=QViEumckqkk

The second link is a silly short movie demonstrating many of the features of the jit-ogre external (and dedicated to josh goldberg). The ninja mesh is also part of the ogre3d distribution. The music is Tomahawk.

http://www.youtube.com/watch?v=97eMB0RHR_8

Now, the question. "How do I take my awesome models I created in [insert your modeler of choice] and animate them with this external?"

The answer is, you don't. Just kidding. But seriously, it's not a simple process. I want to emphasize this without sounding condescending, but real time 3D modeling is a highly technical craft that people spend years honing their skills at and make lots of money doing. The reason being, there's a lot of voodoo involved, and its something i know very little about. So it will take you some time to get your model satisfactorily exported if real-time rendering is something you're new at. That being said, it's a relatively straight forward process. And there is only one place where you are going to learn much, the ogre3d artists and content creators forum.

http://www.ogre3d.org/phpBB2/viewforum.php?f=8

Please notice the first four topics are all stickys that will be very useful for you to look at.

In addition, you will want to go here to find the proper exporter for your modeler of choice.

http://www.ogre3d.org/index.php?option=com_content&task=view&id=413&Itemid=133

PLEASE NOTE: The maya 8.5 exporter for the mac is broken. I have fixed it and you can download it here:

http://jitogre.org/ogreMayaExporter_maya8.5_OSX.zip

Lastly, if you really want to know what you're doing with your textures and shaders and such, you will want to familiarize yourself with the ogre material scripts, by reading the manual:

http://www.ogre3d.org/docs/manual/manual_14.html#SEC23

So on to the external. I have created some tutorial videos which will hopefully make learning this thing less painful. This is my first project for public consumption, and I have no idea if I have created this in a way that will make sense to others. I hope I have, but you'll see for yourself. here are the links to the vids in the order you should watch them:

Below is the link to the files you need to install to use this. Please see the above videos and look at the README file for installation instructions.

PLEASE NOTE: In case you don't actually want to listen to my raspy voice for 30 mins to learn how to use this, you MUST do the following steps to get this to work:

1. Bang the render context (or just turn on the metro). the window will go black.

2. Send the window to fullscreen (press escape). the ninja should appear.

3. You can now restore the screen size and do whatever you want.

you must do these steps every time you initialize the gl context.

Also, if you get a message in the max window complaining about "View Matrix not affine" or some such nonsense, reset the jit.gl.handle.

capture: i have a strategy for this, but i didn't have time to implement it. hopefully it won't be too long to get capture working. this is first priority.

multiple texture units: currently, applying a jit.gl.texture to a jit-ogre object, requires a single texture unit. hope to get that fixed to allow for multi-texturing

jit.gl.shader: it's possible that this will never work correctly, but if enough people want it...

All the bugs that you find and report to me at support _at_ jitogre.org

Additional SceneManagers and environment rendering (skyboxes, particle systems, paging landscape, terrain, portal zone)

My last note. ogre is a beast. he is an incredibly well written, well documented and well supported beast, but he is a beast. also, this is just the tip of the iceberg. I will be open sourcing the entire project (still waiting on my SourceForge project approval) and my hope is that other developers will jump in and add functionality and fix bugs and do things i never thought of.

Also, Ogre likes good cards (ATI, NVIDIA). Ogre doesn't like dumb cards (Intel GMA aka the macbook card). he will do his best, but don't expect miracles.

Real-time rendering is voodoo, and dealing with different card vendors and drivers and vram and all this stuff tends to be a headache. so much patience is required.

This project was made possible with the help of several people.

Wow, great job. Ninja running backwards? I nearly choked on my coffee. Love it.

This gives me hope for our upcoming 3D projects.

Wow, great job.  Ninja running backwards? I nearly choked on my coffee.  Love it.

You effin w00t? wow, great work!!! Can't wait to work with this on XP :)

It will take some time to get into this. I hope I'll have that time soon.

Thank you. Sharing is, indeed, fun... wow.

Awesome! Now I can bring Maya into the mix... :)

Any chance you'll be updating an exporter for Maya2008 OSX?

don't have maya 2008, so no way for me to test, but the one i link to might actually work fine. try it out and let us know.

i would love to hear some success stories from folks exporting their models.

I would really love to *see* some success stories, or even better; *download* some success stories ;)

You have done a great job your thesis. You did a lot of efforts on it. The

thesis is really amazing. You are so talented.

many thanks for everyones kind words regarding this external.

now that the holidays are over, i am ready to continue work on this. I expected to receive a lot of emails or forum posts from people with problems or questions, but there have been surprisingly few. i would love to know if people are getting the hang of the external or not, and see some screens, web-movies, or patches of what people have managed to do. else, please let me know if it's just too convoluted to get anything done.

if people request it, i can make another tutorial movie on how to export models and animations from maya (maya is the only modeling tool i know and use), which will hopefully clear up some of that mystery.

I have managed to build the external as a Universal Binary, and i tested it somewhat successfully on my old ass g4 with a crap card with 0 shader support. animations work fine on this machine, but not much else. also the following error is printed every draw call:

ob3d_draw_end popmatrix: GL Error: Invalid enumeration

unfortunately, i don't think i'll have the time or inclination to track that error down, but perhaps it's related to the crappy card and not to PPC in general. if any dev's have any ideas regarding this, please let me know.

PPC users, please test this out and post back your results.

Not sure off the top of my head, other than some potentially newer 

things you're trying to do on HW which doesn't support it. The 

invalid enumeration might happen inside your object's draw code 

rather than inside ob3d_draw_end, and we're simply reporting the 

error there. You can try adding jit_gl_report_error("doing some thing 

in my object") to various places in your object's code, which is 

essentially a wrapper for glGetError() and post(), to see if it's 

Another thing that you might find useful is that even on Intel, you 

should be able to test the PPC portion of your UB object by selecting 

"Open Using Rosetta" for MaxMSP 4.6.3 in the GetInfo window. This 

should load Max and any externals as PPC.

Good luck, and thanks for sharing such an excellent object with the

hi Robert, can you shed some light on the current state of jit.ogre?

i can only imagine the scale of the project. really impressive.

i'm still macless so i can only ask (you or other users), is it possible to

apply different animations simultaneously to a model? blending, different

in the animation.mov demo you touch on this subject briefly but it isn't

clear if the weight is global or per animation sequence.

hi Robert, can you shed some light on the current state of jit.ogre?
i can only imagine the scale of the project. really impressive.
i'm still macless so i can only ask (you or other users), is it possible to
apply different animations simultaneously to a model? blending, different
weights, blend between animations, etc.
in the animation.mov demo you touch on this subject briefly but it isn't
clear if the weight is global or per animation sequence.
thanks again.

rob will answer better, but just a quick shot:

you export your model with different animations and in jitter you can 

use all these actions separately or also together. you can set the 

weight of each animation and the speed independently, and that gives you 

the possibility to mix/blend several animations together.

using "walk" and "jump" together will result in some jumpwalk.

regarding the state of jit.ogre, I would say it takes a while until you 

figure out how the object is working, there is a little learning process 

involved before you can actually use it. also you need to find (or 

create) models that are exported with skeleton animations that can be 

used, which can also be not so easy (btw I was using blender), but 

the jit-ogre project (aka animated 3D models in jitter)
