   Spline Roads
  Know any good tutorials for calculating spline shaped roads from a selection of points in 2D or 3D? I will need to calculate the inbetween points as well for collision detection purposes?   
A link to a 3D spline tutorial.   ;Quote:Original post by paulbirdI will need to calculate the inbetween points as well for collision detection purposes?I'd say so. If it's 3d, you're better off tesselating all the points and just doing per-poly collision detection.  The math gets really ugly really quickly otherwise and you're usually forced to use a numerical solution anyway.
