Next question I have with camera is: is the camera.x, .y,.z an absolute coordinate independent from pan, tilt and roll?
I used: vec_set(camera.x, vector (-40, 20,30));
and found out a strange behaviour. ths axis are twistet.
-40 equals .z, 20 equals .y, and 30 equals .x
The same is with the colour vector which I changed in the atype.h that red is always the first colour vector. Why is this? Every graphical program I know has red as the first vector.
