Is it possible to use some big texture to "cover" some surface mesh to achieve an effect with THREEJS like this:

, without manual UV mapping? (I have TIN and point cloud as "surface source")

I need it for interactive 3D heatmap which should operate huge InSAR pointcloud dataset (I use points buffer geometry with custom displacement attribute and LUT now).

In the example you show, normalizing X/Z coordinates to the range 0-1 would give you good enough UVs. Vertices with the same Y height would all have the same color. – Don McCurdy Mar 23 '18 at 14:37
What is "TIN" in this context? – pailhead Mar 26 '18 at 18:36
TIN here is a surface mesh (point triangulation). Looks that I really need to calculate UVs for each face by X,Z and forget about Y – SalientBrain Apr 15 '18 at 21:50
