A Blender addon to add randomized geometry to any mesh

RandoMesh

v0.1.1

A Blender addon to add randomized geometry to any mesh. Supports Blender 2.80.
To install, download the zip file and install as an addon in the Blender preferences panel.

RandoMesh works by taking your geometry and adding random subdivisions to it. It was created to start learning Python in Blender and automate some of my workflow, so expect bugs. Make sure to always save your work before using this addon!

I've found the best results occur with meshes under 5000 polygons. Lots of iterations can really slow things down, so beware. Opening blender from a terminal will give you detailed output of each step of the process.

Example (Subdivision smoothing set to 1.0)

Processing Log (Example terminal output):

Iterations: 5
--------
Iteration #1: 0.226s	G:12 | S:1 | Extrude: -0.0009	P:T	T:F
Iteration #2: 0.507s	G:6  | S:2 | Extrude: -0.0007	P:F	T:F
Iteration #3: 1.453s	G:7  | S:3 | Extrude: -0.0006	P:T	T:F
Iteration #4: 1.738s	G:7  | S:3 | Extrude: 0.0007	P:T	T:F
Iteration #5: 1.671s	G:7  | S:3 | Extrude: 0.0007	P:F	T:F

Decimation: 1.4232s	Ratio: 0.29
Smoothing: 1.7921s	Iterations: 7
Done! (10.0s total)

randomesh's Issues

Blender dont see addon

I use latest build of blender and it does not see Your addon.

Got an error

Got this error when pressing destroy mesh. Noticed it was already a problem and supposed to be fixed, but yeah idk.

While using RandoMesh getting the Python error

Humble Feature request: Texture to geometry

Hi Mantissa, Hope you are doing well.

This is a great addon.
Any chance this is possible in Blender?

With an id map texture, you can create a topology with edge boundaries around the colors specified in the maps. If the texture is tiled, the topology is created on the geo as it was tiled with the topology pattern being the same for each location of color.

I love your work. I am not sure why Blender doesn't have it. I have looked at Mesh lab but I don't think it is possible. I have also looked at inkscape, importing svg in Blender but that might be problematic if the mesh isn't flat.

This makes the creation of patterns on complex meshes simpler and straight forward. I am still wondering if triplanar mapping the texture would work before converting the texture to geometry.

I consider it very useful and wanted to humbly ask if it could be added to RandoMesh or a new addon if you feel that would be more appropriate.

Also thank you so much for sharing your tools with us.

Thanks
