Command line utility for converting a UV textured Wavefront OBJ to an adaptively subdivided OBJ with vertex colors, intended for 3D printing.

Run tex2vert --help for help.

• Incomprehensible code

• Questionable math

• Probably buggy

• Input is expected to be a Blender export

  • Must be manifold

  • UVs must be right-handed ("OpenGL")

  • Uses diffuse color for untextured meshes

  • Ideally pre-triangulated; cut N-gons into grid-like structures for best results

• Output is non-deterministic due to multithreading, topologically and visually

  • Colors on UV seams are chosen by the first evaluated triangle

• Output discards info irrelevant to 3D printing

  • Merges all objects into a single one

• Output colors are encoded as nonlinear SRGB
