I'm using a color background. The 3D objects themselves are not being
occluded, it's the underlying vector graphics that are being occluded. That
is, I'm rendering the 3D scene to an off-screen buffer, copying the image,
then drawing it to a graphics context. So ideally, the background color
should be transparent.
Cheers,
Tater
The background should not be occluding your objects. Are you using
background geometry, image or color?
