[Plib-users] plib and shadows

[<Rol...@t-...>]

Hi,

As a newbie in OpenGL and plib I searched the web for  possibilities  to have 
shadows in a scene. I found one simple tutorial for pure OpenGL from a guy at 
nvidia using the stencil buffer.
Now, this requires to draw the scene twice - one for the projection on the 
ground and one to actually show the scene. It's working fine with an object 
created using OpenGL directly, but I would like to use modelled scenes from 
AC3d and benefit from plib's features.

Is it possible to make SSG draw the scene with some settings and 
transformation and stencil buffer, so that the shadows can be calculated ?
ssgCullAndDraw() don't seem to work as it's setting up OpenGL  the way it 
needs it to draw it from the eye's point of view.
Maybe there are other ways to get shadows with plib ?

Thanks in Advance,
Rolf
