Hi guys, I want to try out the new point sprite extension but after having read the spec a few times I'm not sure how to implement it. There doesn't seem to be a tutorial/demo for it yet. Does anyone know how to use it? Presumably I need to bind a texture, enable NV_POINT_SPRITE then render the points? enabling Texture_2D and drawing with points is slow and draws nothing. Looking at the spec I think I need to use COORD_REPLACE_NV somewhere but I'm not sure where/why.
Will the point sprite size vary with Z or will it behave like GL_POINTS?
