i hope this is not off topic but my math is very poor..

i used

        shared->xpos += -100 * sin(shared->head) * cos(shared->pitch);
        shared->ypos += -100 * sin(shared->head) * cos(shared->pitch);
        shared->zpos += -100 * sin(shared->pitch) * sin(shared->head);

to specify the position of 100 behind the position where im at to set xpos
ypos and zpos. Is that right?

thanks, mike

ps: anybody has any good book to suggest on 3d maths?
