sdfgen

Stand-alone GPU-based signed distance field generator from 3D triangle meshes. Used in Armory, written in Haxe and Kha.

Run

Takes mesh.obj file and outputs raw 50x50x50 (50x2500) volume of floats into out.bin. This volume can be loaded into a 3D texture using R32/R16 format.

git clone https://github.com/armory3d/sdfgen
cd sdfgen/build/krom

Windows

./run_windows.bat

Linux

./run_linux.sh

MacOS

./run_macos.sh

Viewer

A simple viewer is included. Copy resulting out.bin file into sdfgen/viewer/build/krom.

cd sdfgen/viewer/build/krom
./run_windows.bat
./run_macos.sh
./run_linux.sh

An included mesh.obj file:

Currently results into this:
