The voxel tools offer ligthweight voxel geometry for Rhino. It allows you to quickly generate and manipulate voxelated geometry from meshes, breps, curves and points, and offers boolean operation between voxelgrids. It can convert voxelgrids to solid mesh hulls.

Rhino 6/7 Use the yak package manager in Rhino 6 or Rhino 7, using the command TestPackageManager in Rhino 6 or PackageManger in Rhino 7, and search for VoxelTools

Alternatively: Rhino 5/6/7: Download the VoxelTools.zip, and place it in %appdata%/components.

• Closed mesh 01_closed_mesh.gh
• Open Mesh with attractor distance 02_closed_mesh.gh
• Closed Brep 03_closed_brep.gh
• Open Brep with attractor distance 04_open_brep.gh
• Curve with attractor distance 05_curve.gh
• Points with attractor distance 06_points.gh

For grids of the same size, you can do boolean operations. Boolean operations on voxelgrids are very quick and lightweight.

• For support please do not e-mail me personally, but find me (@arendvw) on the McNeel forum, use the tag VoxelTools

• Cleaned up code base and merged old projects for open source release\
• Component GridToBoxes: Made both outputs consistent, added output selector
• Mesh casting: Default casting to mesh is now without false colors
• Mesh hull: Added non-default option to add false colors to the mesh
• Voxelate Meshes: Closed meshes are now voxelized much better
• Voxelate Curves: Curves are voxelated faster and more precise
• Voxelate Open Breps: Open breps can now also be voxelized with an attractor distance
• Improved warnings in marching cubes from boolean grid
• Added icons for grid to hex and hex to grid
• Obscured non-obvious (pixelgrid) or why factory specific components
• Added documentation

Legacy VoxelTools - Legacy version that has circulated on the forums, The Why Factory and other places. Use this version if somehow your older scripts are not compatible with the new version, but upgrade when you can.
