Harnack Tracing in Blender

This repository contains our Blender implementation of the algorithm described in Ray Tracing Harmonic Functions for ray tracing harmonic functions.

Building

Here are the commands that I use to build this code on a Mac. First, Blender requires svn (which can be installed using e.g. brew install svn).

Then, you can run the following commands to build and launch Blender

mkdir blender
cd blender
git clone git@github.com:MarkGillespie/harnack-blender.git blender-git
cd blender-git
make update
make -j11
../build_darwin/bin/Blender.app/Contents/MacOS/Blender

Code

Most of our new code can be found in intern/cycles/kernel/geom/nonplanar_polygon_intersect.h and intern/cycles/kernel/geom/harnack.ipp

Acknowledgements

Elliptic integrals are evaluated using code by John Burkardt, available here.
