Subject: Need help with basics of 3d programming and OpenGL
Posted: 15 Dec 2012 07:23:21 pm (GMT -5)
Hello! I want to make a 3d game, or at least start it, using OpenGL. I have absolutely no experience in 3d at all, i did however, make some simple games in 2d, so the game mechanics is not new to me.
Basically the knowledge im lacking is how the 3d graphics work. For example i had problem understanding what this piece of code(in Java) means:
Code:
and i got this link for an answer:http://www.songho.ca/opengl/gl_transform.html
This link explains the basic concepts of 3d programming, but my problem is that i cant understand it because i dont know basics beneath these basics, like for example what "eye coordinates" or "clip coordinates" mean.
By searching in google im either only finding very specific tutorials and articles on how to actually program stuff, or advanced articles like the one above that i dont understand.
Im not really asking you to explain it to me, because i know its a ton of information, but maybe you know some links to sites where i could get introduced to 3d programming without having any background?

Code:
GL11.glMatrixMode(GL11.GL_PROJECTION);
GL11.glLoadIdentity();
GL11.glOrtho(0, 800, 0, 600, 1, -1);
GL11.glMatrixMode(GL11.GL_MODELVIEW);
