Collada with CellShader and PointLight3D
Pretty much the same as the last example, but this one has a Cell Shader overlaying the BitmapMaterial. Also, the light follows the camera as the camera orbits the collada model.
Drag mouse to orbit. Scroll wheel to zoom.

1 Comment to Collada with CellShader and PointLight3D
I try to use a COLLADA file with many triangles…It is very difficult to manipulate the object on the scene, I try to modify the framerate …It works to slowly….
My question is what to do to have a better render on the scene …
