1)How to get the size of screen or window in OpenGL,and when the origin of coordinate changes at z axis,how the visible area on screen change? 2)Is there a easy method to draw a ball with OpenGL? Thanks! [edited by - skyx on May 10, 2003 3:12:31 AM]

1. Er... not sure what you''re asking here. You know the extents, because you set them with glViewport and the matrices.

2. Yeah, check out the glu quadrics functions.

How appropriate. You fight like a cow.

There is no OpenGL function that can be used to set up the window size. You have to rely on your OS to do that for you.
