length = sqrt(x*x + y*y) Is there an other (faster) way to calculate the length of the hypotenuse? I know this is not directly a OpenGL theme, but I need it to optimise my OpenGL program!

have a looksy on the internet theres heaps of examples of quick squareroots eg

Thank's Zedzeek! I've a very big Assembler Book, and now I've a reason to use it! Maybe I could improve my program with this.
