[postgis-users] Delaunay Triangulation

[Bernhard Reimar Hoefle]

Hi,
has someone written a function for the Delaunay Triangulation of point datasets
in PostGIS?

I would like to get the slope and aspect for points (huge amount of lidar points
representing the terrain). Therefore I have to construct a terrain model (e.g.
TIN) and then extract the slope and aspect for each point.

There is the function convexhull(). So I'm wondering if someone tried the
Delaunay Triangulation.

Thanks,
Bernhard
