Linearly Transformed Cosines Offline Fitting Code
This is the code base for the BRDF alignment step of the LTC paper.

The code in this repository does not drastically change the fitting process. It does include additional code for JSON and PNG formats.
###One small note
If you're having trouble compiling with the given makefile, you might need to download and install ImageMagick and GraphicsMagick. A simple brew install worked on my mac.
Full credit goes to the team at Unity for writing this code.
