Hi I am new to paraview and ttk. I want to analyze the terrain but i am not able to figureout how to start with it.

I have elevation map data in json file in one dimension array representing height of mesh.

My first dillema is how can i generate the mesh with that heightmap in paraview?

I am using paraview 5.10.1

Hi @Pravin_Poudel ,

You need to project that height data on your data, I think this requires a programmable filter to read and project the data.

After that, you can just use WarpByScalar filter.

Best,
