A way to do splines?

I am trying to find a way of creating spline paths for objects to travel along. I know what I want it to do but my brain just wont compute the maths for me. In the above diagram there are two red points which I want to travel between. But I want it to distort towards the orange point. So the path I want the green arrow to travel is marked with a blue line. How would I go about doing this mathmaticly? Or if you really feel like a challenge, a small blitz sample would be nice. :) Thanks in advance, Ian |

| Ok i had a look at that, but i see no easy way of making an object travel along that path... Any suggestions? |

| I am no good at 3D stuff too so I would cheat here. You can put 3+ waypoints at the peak (where the orange ball is) and a waypoint at the end position then 'PointEntity' your way through. |

| Something on the archives for bmax, might be useful. http://www.blitzbasic.com/codearcs/codearcs.php?code=1523 |

| Here is another one called Natural Cubic spline. In this variant, the curve would travel through the orange point instead of just being affected by it. http://www.blitzbasic.com/codearcs/codearcs.php?code=1100 Check the drawspline function on how to retrieve the points along the curve. |
