Oscar thanks for sharing these. A lot of interesting projects come to mind.
I've been dalllying a bit with height maps, but get such enormous file sizes that they're freezing my computer. What software are you using?I've been going back to some of my old models and seeing how they look as depth maps. Some worked okay, some looked like a 3 year old made them and some just didn't work.
Here are a few that were good or okay. A little bit of everything. Hope they are of use to someone.
I was just trying to use a couple of sketchup plugins called "Mesh from Bitmap" and "Mesh from BMP". I had to make the tests such a small resolution that they're unusable. I've had limited success with drawing simple geometric shapes in sketchup, saving them as a sketchup file, then importing it into Vcarve Pro. Those worked and carved just fine. But I had tried taking a terrain map from terrain.party of a hilly area near me and saving it as a bitmap. When that didn't work, I took it into Blender and exported it as an stl, then into an online converter and got an stl file, since that's what sketchup will import. That also froze the computer.Mike, your welcome. Hopefully some can be of use to you.
Jim, that is weird. The files should not be that huge. The beauty of depth map renders are they are just pictures.
What software are you using?
Wow, this is great info, Oscar. I just downloaded meshlabs and will try it out. And I'll also look at what Blender will do. Thanks!Jim, I am sorry. I misunderstood the original question. I thought you were talking about the images themselves (creating depth map images). Converting the images to geometry can create humongous files if not careful.
There are different work flows to attempt to reduce the size of the project. I am not familiar with Mesh from Bitmap or Mesh from BMP.
Blender can create geometry from the depth map files which can then be exported as an STL, FBX or OBJ. On the other end, if you have a huge 3d model file, Blender was so-so at reducing geometry size but with version 2.81 it just got some serious help retopologizing geometry (resurfacing the surface with new geometry).
Different workflow. If you have a mesh created (humongous file), meshlabs is a free and very good program to reduce the size of the file while maintaining very good geometry envelope structure.
Sorry not a lot of help.
