3D Graphics Modelling and Rendering mini-HOWTO by Dane Jarvis (classic novels txt) π
So the graphics library, then, can be thought of as the low-level graphics primatives used to build more complex objects (spheres, boxes, complex polygons, etc.). Those complex objects are then used to build even more complicated shapes and figures.
The graphics library installed was the freeware implementation of OpenGL called Mesa.
2.2. The Graphics Modeller
Since the graphics renderer is, ideally, completely hidden from the end-user, we'll deal with that last (besides which, modelling is the next logical step in keeping with my house-building analogy). However, when it comes to the actual i

surface properties of the objects). Make certain that your light
source is:
1. pointing (rotated and translated) in the correct direction;
2. intense enough to actually cast discernable lighting.
4.2. Tutorials
The most basic thing a person would want to do with
modelling/rendering packages is position a sphere on a surface, give
it some lighting, and see the result. A decent tutorial should
describe that first.
That said, The Mops has a wonderful first tutorial

Here are some links that donβt really fit into any other category, yet
are still worthwhile checking out if you are seriously considering
using your Linux computer as a 3D modelling and rendering machine.
