[osg-users] Projective texture mapping

[Michael Scott]

Hi,

I am trying to set up projective texture mapping in OpenSceneGraph. As a first attempt, I modified the osgspotlight example code by basically inserting my own spot light image. This works, but the texture is projected onto all geometry of the scene in the direction of the projection (it goes through meshes). A back projection is also produced.

How can you implement projective texture mapping in OSG as is done by a real projector?

Thank you!

Cheers,

Michael
