Aug 21 2011back-face culling

I recently found a tutorial on back-face culling. It means telling OpenGL not to draw invisible faces (faces on the back side ;) ) of a mesh, which does speed up the rendering a lot.

I was looking for something like this after I increased the height of the world in Mineshooter …

Aug 10 2011Mouselook and SDL - Code

Okay, here is some code for mouselook with SDL…

struct {
              int x, y;
              //In this case: the position where the mouse is held at
              bool trap; //flag for holding mouse at one place
          } mouse;

          void MouseMotion(){
              /* Set x and y to the current mouse position */

              SDL_GetMouseState(&x …

Aug 10 2011Fixed the SDL and Mouselook Problem

After spending hours trying to figure out why my mouselook function didn’t work with SDL, I finally got a solution.

Continued work on Mineshooter!

I just read a blog-article from manwithsteelnerves about z-fighting which really motivated me to continue 3D-programming with OpenGL. That’s why I decided to continue my Mineshooter project and here is a new screenshot.

What I did: I had stopped developing this game, because of difficulties …

This is the last of the projects I’m currently working on. It’s called “Notenspiel” (German), probably could translate it to “Note Game” (Meaning musical notes).

You can see your points in the top-left (yes, “Punkte” is German for points :) ), you get them by pressing the right key on …
