ISETRTF: Using ray transfer functions for camera simulation in PBRT with unknown lens designs

Repository for software to support the analyses in the paper on ray transfer functions

Requirements to run

Dependencies

1. ISET cam: https://github.com/ISET/isetcam
2. ISET Lens: https://github.com/ISET/isetlens
3. ISET 3D: https://github.com/ISET/iset3d-v3
4. JSONio: https://github.com/gllmflndn/JSONio

Unpack ZIP files

In the directory 'paper/data/zemaxratrace/' unzip the archive file to obtain the datasets produces by the zemax macro. This is required before running ''generateRTFfromzemax.m'

Example

An example is given in the examples folder. The general use of the software is

1. Generate a ray dataset using the zemax macro (see paper/zemax/zemaxMacroRTF.ZPL)

2. Generate a RTF Json file using the fitting scripts

3. Render a scene in PBRT using the RTF camera
