I am trying to show triangle cells with elevations similar to a TIN in GIS. I represent my cells with polygons in SharpMap. In, you can show them with CreateGraphics.FillPath(pathBrush, path) to show different elevations at the vertexes and at the center. However, in SharpMap I can only find the following example

which shows polygons with different fills, but a uniform fill in a polygon.

Many thanks for your help.

I doubt that you can do this with a theme, you'd have to write your own "TIN" Layer for that.

can you give me some ideas as how to write and display a "TIN" layer? Thanks. Victor
