Hello, I have been working with openGL since 2008. A few years ago I had to migrate to DX but I will always have opengl in my heart . There was a thing I never acomplished when working with opengl. That thing was to make 2D sprites to move across the screen without performance issues. I have tried almost everything, GL_EXT_TEXTURE_RECTANGLE, glu MIP MAPS for NPOT textures, display lists, and anything seemed to work, attached is a sample using texture rectangle. My question is how a 2D opengl programer manages to make a fluid 2D opengl application, what are the tips, etc. I would really appreciate all the help you can give me. I have been programming in 3D for a looong time and that is the only thing I wish to know more.
BTW I have a 3D dev blog wwww.vasilydev.blogspot.com, stop by and take a look.
