Hmmm...
C++, GDI Algebra... That's all? |

I would recommend starting with a 2D engine first (like a tile-based game). Don't forget you can mix polygons with plain 2D stuff. In fact, a polygon is a 2D shape, so all 3D accelerators can be used in 2D engines (for example, to rapidly blit texture-mapped tiles to the screen). Then, when you're comfortable with that, move on to some pseudo-3D stuff, like a slivering engine. If you don't know what that is, it's an engine that builds up a 3D view from multiple verticle 'slivers' which are scaled in height according to how far they are from the camera location. Old games like Heretic, Hexen, and the original DOOM used this technique. This approach should yield satisfactory performance on modern machines, even if you're using GDI. After you've gotten that down, you can move on to DirectX and a pure-polygon 3D engine.

Sure I 'll start from 2d.
The problem is how to descibe points (vertices) in a 3d world (basicaly, describe a 3d world) (in all this I mean the idea of how to discribe a 3d world).... |

A vertex is just an xyz coordinate...
In OpenGl, if you wanted to draw an object, you could make every vertex yourself if you wanted to using glVertex(x,y,z)... glBegin(GL_TRIANGLES); glVertex3f(0.0,1.0,0.0); glVertex3f(-1.0,0.0,0.0); glVertex3f(1.0,0.0,0.0); glEnd();

I know this...
The vertices are just points in the 3d world. |

Also, I heard that with c++ and some ready libraries can let me "talk" through an (windows) interface to the graphics card / or just "play" with pixels....

How is code for a GPU written anyway, do they have their own assembly languages?
