[osg-users] Using vertex attributes

ther vertex attrib code I could find in the source tree. Is there no way for an app to associate vertex attrib data with a variable name string (like Uniforms)? If not, why not? And would you be open to a code submission that adds this functionality? Thanks. -- Paul Martz Skew Matrix Sof

with names identical to the old GLSL 1.20 uniform and vertex attribute names (that would be a mistake in my opinion, as uniforms and vertex attributes starting with "gl_" are reserved)? Or have a simply misunderstood the point of this code? Thanks. -- Paul Martz Skew Matrix Software LLC http:/

Re: [osg-users] Multiple projective textures - Conditional per Pixel Multipass rendering

I believe you can use a uniform array of samplers. This means the number of texture can be arbitrary and therefore you don't need to recompile your shader based on number of textures. Paul Martz Skew Matrix Software LLC http://www.skew-matrix.com +1 303 859 9466 Johannes Schüth
