+8Hi,
I have a number of points which I like to create triangle polygons from to form a sort of elevation wall. The desired way of creating them is to have the lower ground (red points) as focus.
Let's say the first two points (A and B) derives from upper green points, then the third point (C) would be the closest vertical red point. Please see illustrated image and attached file.
Thanks!
+55NieghbourFinder is my first thought. The red points will be the candidate and the green the base. This will then fidn the closest red point to each green point. You can then use those two vertices to make the line
+8Thanks for the suggestion @hkingsbury. Will also have a look into that.
After reviewing my previous asked question I went back to the initial idea to extrude edge boundaries of the terrain downwards. The problem is that inefficient number of faces are created and some with gaps depending on terrain complexity. I then found the MeshSimplifier transformer suitable for optimizing faces.
To minimize overlapped faces after optimization, the trick was to split the terrain elevation into parts relative to a certain width of combined faces. Then aggregate using NeighborhoodAggregator transformer.
