Interpolation errors - spikes!

Post by duke »

I've found that splineland isn't working very well with ramps or sharp changes in elevation (such as cliffs and retaining walls). Please see attached image and scene:

A way to approach this in code would be to scale the Z interpolation by the non-interpolated curvature, such that steeper areas have less Z interpolation.
