Hi everyone, I've finally put together a website with some informations, videos and examples of the 3D OpenGL Viewer I've built using Processing so I'm updating this thread too with recent info.

The new link is:

Let me know what you think,
Michele

Partial feature list:

- based on the Collada 1.4.1 file format, supported by most 3D applications like Autodesk Softimage, Maya, 3dsmax, etc.;
- HDR image-based lighting, toon shaders and compositing effects like vignetting, fake (fast) chromatic aberration;
- support for polygon objects (as triangles), hierarchies, instances, normals, vertex colors, texture projections, basic material types, component clusters, textures, lights, cameras, hierarchical transforms, and more;
- user interface can be completely customized;
- objects can have multiple materials, which can be organized into presets and swapped in groups by clicking a single icon;
- scenes can have multiple camera snapshots;
- presentations can contain multiple scenes;
- camera physics and interaction range can be fully customized;
- configuration settings and data files are XML-based and can be edited manually or using additional tools;
- settings, shaders and effects can be tested interactively during the design phase;
- the following OpenGL features are supported by the Player (when available on hardware): GLSL shaders, HDR image-based lighting, toon shading, per-pixel lighting, environment mapping, anisotropic texture filtering, mipmapping and more;
- preloader that initializes and uploads data to the GPU;
- runs on every gpu that has OpenGL 1.3 or higher - shaders require OpenGL 2 or higher.

Hi Jeff, thanks for the positive comment. Btw the development for this viewer took a lot of time, research and work, so I don't think I'll release it as a free library for now.
