See this page? There's not that a whole much there, is there. What is behind all that, however, is the functionality for tsumea members to upload exported Unity 3D files to the site for display.
I've been planning some quick 2D and 3D activities for members to partake and in, and for the 3D part, the idea is to have a fortnightly assignment where we all model something covering the same theme and upload it on the site for all to see and discuss. These are really small assignments (100 / 200 polygon models with 256k / 512k texture sheet etc) which most people should be able to complete within a two week time slot. Participants will need to use the Unity 3D program (the free indie version) to export their model and upload it to the site where it can be viewed via the Unity web plugin.
Unfortunately, my Unity 3D-fu is rather weak, and I'm hoping someone here could develop and create a simple object viewing project with tsumea (and anyone else who's interested in it, really), plus a straight forward tutorial to explain how participants can use it (from loading the project, importing a model, and exporting it). The object viewer doesn't need to be too snazzy, I guess it needs to auto-rotate the object upon viewing it, and some basic controls like stop rotate, rotate (x / Y axis), zoom in/out, reset position etc.
I'm pretty sure something like this is really basic to do, but if anyone could help out, you will have my utmost gratitude! Give me a yell on the tsumea contact page if you can offer some assistance!
