Shadows Sample

A little experiment I made while working with shadows. It's simply a thin cube with the Away logo in it (PhongMovieMaterial) and 3 hovering lights spinning around its top. Each light projects a shadow on the floor, which is simply a large plane that has the same color as the background. Shadow projection is almost done at this point, I just need to optimize the projection of faces, that is, the decision of which faces should be drawn on the surface, and which drawings would be redundant. Besides that, it looks pretty nice so far!

Preliminary Shadows and Reflections

I'm currently working on standalone shadows and reflections classes for Away3D. Shadows should be handled by a light object with the ability to project registered objects into a given plane, and reflections should be handled by reflective planes that should support reflections, refractions and bumpmapping. The techniques used do not rely on secondary cameras or viewports and were inspired on zupko's raycasting technique explained here. Hopefully, if all goes well, these features might be included in future versions of the Away3D engine.
