I need use the OpenGL to draw the frame data instead of GDI+, because GDI+ is too slow. But I am afraid that the OpenGL sdk cannot support all the windows platform. Which version of OpenGL sdk can support xp and win7. Another, I need to draw image button on the frame data. Who meet the similiar problems?
OpenGl runs on all windows platforms but there is no OpenGL sdk. Try reading some tutorials on creating an OpenGL program. http://www.opengl-tutorial.org/ is a good start.
