I need to get sth done but im not sure about tzhe best approach, as i dont have so much experience with splines actually.
Here's the problem:
Imagine you have some arbitrary spline and you want everything beyond a certain X-value to be flat, just like you booled it with an rectangle, that came in from the side.
My first idea was to use the built-in GetPosition(t) and GetTangent(t) function which would give me a vector position and a tangent for that position on the spline, in regards to its length (t: 0->1.0).
The problem is though i dont have that 't' value. all i have is an x-value like, everything beyond x=20.0 should be flat.
What i need is all points on the spline, that have x=20.0 *and* the tangents of those points.
Any ideas how to do that ?
Maybe the SplineHelp class can help there, but it looks like all important functions work on the length of the spline exclusively.
