Distance Fields

Distance fields seem to be back in vogue. This tiny project features a distance field generator - it converts an input polygonal mesh into a 3D texture of closest distance values. Uses Assimp and CGAL [1]. Also includes a GLFW raymarching example (online here).

Build

Uses cmake. Build with something like

mkdir -p build/debug/
cd build/debug/
cmake -G 'Unix Makefiles' ../../
make

To build the example with Emscripten (for the Web)

make release -f EmscriptenMakefile

See the makefile for more details.

Dependencies

• Assimp and CGAL
• glfw, glew (example only)
