Hi Peter,
Can't you use compatibility profile ? All stuff you mention is still
available in compatibility profile.
eg place it at the begining of GLSL Shader:
#version 150 compatibility
[shader code]

Subject: [osg-users] Extract ModelView Projection Matrix for GLSL
Programversion 150 and higher
Hi,
gl_ModelViewProjectionMatrix and ftransform() are deprecated since GLSL
Version 120 ( but still working ), in Version 150 not working at all.
Is there a straight forward way to extract the current ModelView and
Projection Matrices ( e.g. from StateSet ? ), without having to pass
around the Camera through the SG, or extract osg::Transform World Matrix ?
Moreover, gl_Vertex is depreciated as well, so how to create a VBO ? Is it
possible to use only VertexAttribArray, without VertexArray, NormalArray,
etc. ?
Thank you!
Cheers,
ParticlePeter
