Middle mouse button drag, and be thankful next time someone teaches you C++.

I can’t read the code… the advertisements kind of push it all into the right and then it’s cut off so basically I just see this:

|Line 21: glClear (GL_COLOR_BUFFER_ …

this is NOT a good thing… because I’m actually trying to follow a tutorial, not GUESS what is actually there. Why is it like this anyway? :] Would you please fix it?

Just remember that objects that are drawn on the
screen are drawn in the order in which you choose to draw them. So if you
draw a square (square1), before another square (square2), then if square1
is brought infront of square2 while square1 has an alpha value, then
square1 will not show square2 behind it.

I think this is the heart of this tutorial and I couldnt get it.

Hey kalin,

This was an old tutorial back before I started tidying up code and moved to glew. Although with the #include “GL\glut.h” line, the #include “GL\gl.h” line becomes redundant.

Cheers,

#include”GL/glew.h” not # include “GL/gl.h”
