Hello Mathieu,
In fact i've got a new problem (perhaps it's normal), the
transformations applied with texgen are not take into account when i use
my shader. Do you have any idea of how to proceed ? I attach a screen
capture of my problem.
If you're using a vertex shader, you must do the TexGen yourself
(because osg::TexGen is fixed vertex pipeline functionality, which is
completely replaced by your vertex shader if you use one).
See the orange book for how to replicate the fixed pipeline OpenGL
TexGen modes. Also, 3DLabs ShaderGen can generate shaders that replicate
the fixed pipeline - see http://www.mew.cx/glsl/shadergen/. You might
have to change the generated shaders to match your ways of doing things,
and it's often not very useful to generate shaders that replicate ALL of
OpenGL's fixed pipeline, but you can at least get inspiration / snippets
from that tool.
Hope this helps,
J-S
