I'm using openscenegraph to apply vertex/fragment shaders to a whole scene.
I'm beginning to suspect an opengl misunderstanding so just a quick question to be sure :
with the same fragment program bound,
can I update its local parameters between
two primitives draw?
in draw1 i get the parameters from draw2, as if the driver changes the program parameters too fast then issues draw1..
any idea? =)
(hw note : quadro fx with nv 4363, since 4496 and 5328 don't like me
