@fenrus Thanks for the work! Been thinking about it off and on all week. I’d made it half-way or so through Terrain Relief Models, Unabridged but this version might open up even more options. One option is that it allows the creation of inlays with a non-flat top surface. Think v-groove following a ripple. I was thinking through the tool-chain earlier, and I think you could use the online tool you’ve created to make the initial height map, then bring that height map into Blender to create an STL. Using booleans you could then make a negative of the STL, machine both parts out of separate materials, glue them together, and then machine off the top to create the non-flat surface. There might also be a (simpler) way to do it without using Blender, and working entirely from height maps, and color inversions.
It probably makes more sense in my head than in the paragraph above, but given the time I have to commit to these sorts of things, it’ll take me a while to get a proof-of-concept together.
Thanks again for making this tool. It’s a big help.
