i need to draw an imaginary line in a 3D world using the slope
method. (terminology is off. been a few years since math class)
if i remember right its the difference of x over the difference of y.
(X1 - X2 ) / (y1 -y2) used to calculate any point on a straight line.
in short im trying to find a way to use this in a 3d world for collision detection(GuNs – path of the bullets/projectiles).
any links would be a big help.
