Creating an irregular 3D Mesh

Programming Questions

This feels like a simple problem that has probably been solved often, but I can't quite find the right information to help me solve it.

Basically I have a set of x,y positions (based on long,lat) that are irregularly positioned on a map.

I simply want to join all these x,y positions together in a 3D mesh.

I will later be varying the z elevation based on values linked to that x,y place (like levels of pollution etc).

Is there a library that will help with this?

I have been using Toxiclibs, but it's Terrain function is creating a uniformly spaced grid.

Any advice or existing demos would be most welcome..

Many Thanks

Mike

Your sketch shows the result of a process called Delaunay triangulation and toxiclibs supports that one too. See examples in this thread:

and specifically:

At current this is only implemented for 2D, but you can then easily convert the resulting triangles into a 3D mesh, e.g.

Hth!

Hi Karsten,

Thanks so much for that... I thought someone must have tackled this already!

I'll check this out and let you know how I get on.

Cheers

Mike (from your recent ODZ workshop :)
