Voxelize.jl

Compute voxel (3D pixels) representations from polygon meshes.

This package implements one algorithm based on the approach of the trimesh library to convert a polygon mesh into a voxel grid represenation. This voxel grid is represented by a 3D Array of Int8, where a non-zero value means that the cell is occupied.

The algorithm splits each edge in half until each piece is smaller then a fraction of the desired voxel size. Then, each vertex position is converted to an index in the grid array and the corresponding value is set to 1.

Roadmap

While the project is working at the moment with the functionality I need, I will want to work on it a little more. Open points are

• Improvement of the output data structure. OffsetArrays.jl could be useful here as well as using the sparse matrices to represent the grid
• Implement different methods for voxelizing a mesh, that are not as naive as the current one
• Performance improvements (even though it runs quite fast for my cases)

I am very open to any contributions and collaborations. Just contact me!
