I got two questions about OpenGL which I cant find good enough explained in my book or on net-tutorials.
1.How do the OpenGL coordinate-system work?
How do i know where for example glVertex3f(1.0,1.0,1.0); is?
From what I have read, I think you set up the coordinatesystem your self with the mix of
Can someone try to explain how I can set up a coordinatesystem which is logical,detailed and easy to use? and try to explain how to simply set up the coordinatesystem to anything you want?
2. Also, from what I've read, the "Eye" or the "Camera" is actually allways at the origin(0.0,0.0,0.0), EVEN when using glTranslate3f() and gluLookat(). WHY? Wouldent it be easier and better to simply move the camera, rather than moving the whole world?
