Hi, It's me again. In order to implement a nice Projective Texture Mapping, I want to project on all visible primitives, and only it. Maybe I'm wrong, and if I am, please tell me, but I projective-texture-map using osg::TexGen that I only can apply on Groups or Geodes (well, anything StateSet-able) so not on primitives. Thus I think of extracting each visible primitive and putting it in a new Geode in order to only texture them. Moreover, I'd like to have several projectors, then having all visible primitives extracted will make the managing of multi-texturing much more easier. This way, I may add a significant number of Geodes to my scene, this may be costful to render.
The other way is to define shaders for these visible primitives. In your opinion, which of these two ways is the more efficient? Thank you!
