hey there! i use the following code:

trace_to.x = my.x + 10000 * cos(my.pan) * cos(my.tilt);
trace_to.y = my.y + 10000 * sin(my.pan) * cos(my.tilt);
trace_to.z = my.z;

now the problem: how can i set the trace_to - point to the right side or the left side? have i only to change the *cos(my.pan) to *cos(my.pan + 90) or what?

thanks, Dj Pint
