Rotate an object around the x, y and z-axis respectively. x,y,z may have values between [0,360] degrees.
You will usually only rotate around one axis, leaving the unused fields on 0, I guess. If you want to
rotate around more than one axis, please note: The order of the rotation applies is y-axis, x-axis, and
then z-axis. You can think of it as the earth position coordinates: x is the longitude, y is the
latitude, and z is the rotation at this point of the earth around your bodies axis. (I wonder if that
makes it any clearer ;)
Warning
Rotate is absolute, not relative!
s3d_rotate(object, 90, 0, 0);
s3d_rotate(object, 180, 0, 0);
// object will be rotated 180 degrees around the x-axis, not 270 degress!
