Wei – this is not what the original poster asked for. Whop42 – we do not have a function for exporting the deformed state of an SCM terrain patch as a heightmap. I’d be curious to know why you would want that in the first place. Nonetheless, you can generate a heightmap image yourself (e.g., with STB which is what we use to initialize an SCM patch from a heightmap). To do that, you can extract the current height of the SCM terrain at the locations you are interested in (SCMDeformableTerrain::GetHeight) or else grab the current visualization mesh ( SCMDeformableTerrain::GetMesh) and then convert these heights to grayscale and load an image pixel-by-pixel, effectively doing the reverse of what we do in SCMDeformableSoil::Initialize<https://github.com/projectchrono/chrono/blob/9ba226bf4866ef13b6c3dce3ae9f16d3ab55acea/src/chrono_vehicle/terrain/SCMDeformableTerrain.cpp#L389>.

Take a look at this demo at line327<https://github.com/projectchrono/chrono/blob/main/src/demos/vehicle/wheeled_models/demo_VEH_HMMWV_DefSoil.cpp#L327>, I think that might be what you would like to find.

I have a simulation rendering properly with a SCMDeformableTerrain instance, but how do I get the information out of that into a .png or something similar?
