S3D_ROTATE(3)							    s3d Manual							     S3D_ROTATE(3)

NAME
       s3d_rotate - rotate object

SYNOPSIS
       #include <s3d.h>

       int s3d_rotate(int object, float x, float y, float z);

DESCRIPTION
       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!
