Hi, I want to assign a generic vertex attribute for each primitive (triangle). I have written a visitor for this and used setVertexAttribArray() and setVertexAttribBinding() to add the id-attribute to the geometry (BIND_PER_PRIMITIVE). I have also added the attribute in the shader and introduced it to the shader program using addBindAttribLocation(), but have not been able to get the desired attribute ID for each triangle. I could do this with a plain opengl code but cannot do it here. I am clearly missing something but I cannot see it clearly. any ideas?
thanks, deniz ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=57156#57156 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
