[ANN] cosm objects (from Expo74)

May 7, 2009 | 2:07 am

hi everyone,
Here’s a link to the cosm objects for spatial audio and virtual environments that Graham and I presented at Expo74. We’ve revised things a bit and provided some documentation.

http://www.allosphere.ucsb.edu/cosm/

cosm contains:
spatial audio objects (ambisonics, doppler shift, distance attentuation)
3D rendering and navigation objects (stereo rendering, quaternion camera movement, collision detection)

Works for Windows/OSX with Max5.

One thing I want to note is that we’ve packaged a number of the externals into one actual external file. This is quite a change from how Max externals are historically packaged, but since all of the objects share common data, it saved us alot of trouble to do it this way.

enjoy!

congrats , this looks fantastic.
i will have to dwelve into for a while before coming up with constructive comments Wink
as this has been developed for stereorgaphics do you have examples/links of works demonstrating cosm’s use ?
thanks for your efforts and sharing

An example in stereo would be the Allobrain project on this page:
http://www.allosphere.ucsb.edu/media.php

We used active stereo, which requires a workstation class graphics card that can do quad buffered stereo. You can also do passive stereo using 2 windows.

There’s an example in the downloads for multi-view projections. That patch is set for 2 windows at 90 degrees to each other although it could be adapted to provide left-right pairs for passive stereo.

I am running max 5.0.7 on a Dual G-5. Installed the cosm.mxo into the max-startup folder. I get this error in max window…
cosm: unable to load object bundle executable

Is it not UB? I am so excited to try these out

Really looking forward to these. Great presentation at the Expo too. My first project idea is to build a Sim-Solar System app where each planet has its own tones… a "Music of the Spheres"… and when the planets line up you’d hear their cool sonorities mixing together. These objects will make this project vastly easier… and that’s just the start with what this can do!

Kudos and many thanks!

These look like they will be hella fun to use. Thanks Wes.

This is astoundingly good stuff, thanks so much. I especially love the flexibility with the up vector in your navigator (I might have to try to add that to my measly little glNav abstraction). I look forward to diving into this library.

seejayjames,

I built a sonic solar system for a Yuri’s Night event a few years back – complete with flight simulation and quad spatialization. We limited ourselves to moons >= 1000 km in diameter, which still left a lot to sonify. Here’s a little fly-through demo (the patch has manual flying, warp speed, and a kind of random tour mode).

Sorry about that, I missed the UB option in the build settings.
I’ve rebuilt them as UB and uploaded to the same url:

Updated Windows versions will probably come next week, because of the wildfires burning in Santa Barbara right now.

Thanks for the UB version! Can’t wait till I have time to play with that. Congrats for this work.

Gorgeous! I really like the detail of the textures and the sounds, especially the low ethereal spacious-sounding ones, which fit really well. I can only imagine what it looks and sounds like as a running patch, with all those controls and rendering in real-time.

So many possibilities with this stuff… I mean, if there were a stellar-exploration app that ran in one of those CAVE environments, complete with cool ambisonics and the ability to create new worlds and sounds, I probably wouldn’t come out of there for a week. Music, 3D, interactivity, astronomy, physics, and Max… yep, it would pretty much be heaven.

my favorites were always the episodes of startrek with the holodeck..

just wanted to see if I could trump the geekyness level of the past message..

Judges?.
