Hello,
I'm using SFML 2.0. I am not an expert on openGL, so please correct me if I'm wrong.
As far as I know, there are multiple properties for vertex in openGL. From what I have seen, in SFML, only texture coords, position, and color are used.
I need to make use of some extra attribute in order to use it in a vertex shader.
From this tutorial I saw this list of attributes:
http://www.opengl.org/sdk/docs/tutorials/ClockworkCoders/attributes.phpI would like to use the gl_normal, or gl_fogcoord, or just use my own attribute, but I see no way to set these attributes on vertex by using SFML.
Is there any way to modify these attributes or using custom attributes on vertexes using SFML?
Thanks,
