Parametrize set of unordered points in 3d space
Let's assume that we have some set of points in 3d space sampled from some arbitrary surface, without self intersections and mostly flat. Is it possible to get any parametrization over this set of poi …

Is there any open-source implementation of n*log(n) visibility graph construction algorithm?
Is there any open-source implementation of n*log(n) visibility graph construction algorithm?
I'm trying to understand S. K. GHOSH and D. M. … MOUNT sweep line algorithm, but it's known for having very hard implementation. It would be great if I saw at least some implementation, in any programming language. Or in pseudo-code. …

Find closest point on surface interpolated by 2d matrix of points
I have rectangular matrix of 3d points sampled from a parametric surface. In my program this matrix provides base points for bilinear interpolation of surface (In any (u,v) point it returns 3d point i …
