Just laying out ideas:

• surfaces, provide 3 dimensions of data that define x, y, z positions
  • apply colormap on surface using 2 dimensions
  • apply a TextureArray on a surface (might be related to the previous point)
• arbitrary polyhedron shapes
• importing meshes and being able to programmatically change x, y, z, positions of the mesh?
