27x Make terrain mesh with Delaunay triangulation

Delaunay triangulation is suitable for create a 3D surface from points cloud or contour lines generally obtained from a topographical survey.

This type of vector representation of land surface is usually called Triangulated irregular network (TIN).

Triangulation from heterogeneous points cloud

Triangulation from contour lines

Triangulation from DEM regular points cloud

Using Delaunay triangulation can also be a strategy to create a TIN from a DEM raster dataset. In this case, the workflow is the following:

  • convert the DEM raster into point features (shapefile) with any GIS software
  • import the shapefile in Blender
  • triangulate the points cloud
