hey kev

i got more tips. i never used the right click "find declaration". this is handy.
also, the "function index" command looks handy too.

was wondering, is it worth making a video to explain the difference between open gl , direct draw / direct x ?

It's easy to start a program, but harder to finish it...

I think that means i am getting old and get side tracked too easy.

  OpenGL  / Direct3D  are 3D api's (although Direct3D includes lots of stuff also, like Input/Sound etc and is windows only).   In both, you bundle up primitives that get sent to the GPU to draw it on the card in the back ground.   They do the same things but form different perspectives.   The OpenGL API is available only many platforms.. So GL is cross platform.

  DirectDraw is for drawing 2D primitives on the GPU, although it doesn't really do much more than image copying/merging/masking stuff, so a blitter in other words.
