As it's SKP formats use the fabulous Free Pcon Planner for texture and Conversion in OBJ https://pcon-planner.com
Here in the funny and easy Flowscape in 10 seconds...
Not yet tested but seems very cool! :)
Free : Tangram + Google Maps + 3D Builder (free integrated (?) or loadable inside Windows) https://tangrams.github.io/heightmapper/
Tested just with an image! That is terrific of simplicity! One second realised! :)
And at the end you can save in several 3D formats! ;)
I don't know if this has been posted here already, but the skilled coder who created the fabulous MagicaVoxel editor has started working on a new tool featuring Signed Distance Fields. It looks very promising.
Wait for the second half of the video to see the live editing of the model.
It's Aerialod by Ephtracy but these new function is not yet released! ;)
But the program is yet usable! We are waiting also colors/textures & ".vox" import ;)
For the moment
ASC format: Defra Data Services Platform
DTM format: HiRISE (NASA)
Support importing and exporting PNG, JPG, TIF image formats as HeightMaps
Support exporting PLY meshes. As 3D export!
For explicite more one of the process! :) (the other will be the 3D Builder who permit to reload in one pass the 117 files obj)
From any Image (here from Flowscape see previous post for the original) we obtain a file format .vox (by FileToVox) reloaded inside MagicaVoxel
But there are a lot of Matricies (here 117) and export result = 117 files OBJ!
This is a 3D volume of voxels who can be exported as OBJ! (here will be 117 files ! )
Here for example a render of the Unic obj File from the 3D Builder Method ;)
Here directly from an image inside free Aerialod (very speedy 2 seconds) but for the moment only format 3D is PLY
You can play with some parameters in Real Time for the 3D result! https://ephtracy.github.io/index.html?page=aerialod
And here from the Unic file OBJ result from the Michael Merge OBJ (it's something like 1 Giga!!! ;)
but that works! (SimLab supports my files 1 - 2 Gigas!!! ) 2 - 3 minutes waiting at the importation :)
