I have a question, which is faster, using 1 long equation or a short one? For example, if i have: -actx[i]*cos(theta)*cos(phi)-acty[i]*sin(theta)*cos(phi)+actz[i]->eyey[i] would that be quicker than dividing it up or is this the shortest way for the processor to process it? If it matters, I am doing this for the 89. THANX Dan
