Introduction

thinvox is a program that reads a 3D voxel file as produced by binvox, and applies a thinning algorithm to it. Currently it only supports the directional thinning method described by Kálmán Palágyi and Attila Kuba in Directional 3D Thinning Using 8 Subiterations, Springer-Verlag Lecture Notes in Computer Science volume 1568, pp. 325-336, 1999.

• input formats:
  
  • .binvox, as produced by the binvox 3D mesh voxelizer
  • MIRA
• output formats:
  
  • .binvox
  • HIPS
  • MIRA
  • VTK
  • a "raw" file format
  • minecraft .schematic
  • Gmsh .msh
  • .nrrd

Download

version 0.37, added 8 March 2021

• Linux 64 bit executable
  compiled under CentOS 7.9, 64-bit
• Windows executable
  compiled using a cross compiler.

(the binaries have been compressed using the UPX executable compressor)(they are self-decompressing)

Usage

Run thinvox without parameters for a usage summary.

Note that for efficiency reasons no boundary checking is done: in other words, make sure that there are no voxels in the outer layer of your model (binvox already enforces this).

Changelog

0.37: fixed orientation and alignment issues for the NRRD format (8 March 2021)
0.36: recompiled thinvox without unnecessary libraries (2 December 2017)
0.35: this border is removed before writing the thinned voxel file (31 July 2011)
0.34: fixed bug: binvox no longer produces voxel models with an empty border, so now thinvox adds one before thinning
