Cnc depth map

[willeykj]

I'm starting to do some 3d carving with my CNC and I'm doing my designs in Sketchup. I need to create depth map greyscale images for import into the CNC software. Is there a simple way to get a depth map out of sketchup?

You could project a bitmap of a gradient 'through' the mesh...

Then export an orthographic view as needed.
