Hello, I'm trying to extend the draw instanced example in such a way that I can position the quads outside of the shader. So I would like to be able to use an array of positions inside the vertex shader that I would index with gl_InstanceID and use that to offset the current instance. The array of positions would then be updated from the render thread every frame in a callback.
Could someone tell me how to set this up in the shader and how to access the array in the callback function? Thanks, Nico _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
