NOTE:
=====

The polarisation renderer code you get with this EGSR submission is 
fully functional, and capable of generating the result images shown in 
the paper. However, it is not properly documented yet, and in this form 
is mainly intended to prove to you, the reviewers, that we actually 
built the sort of system we claim to have developed. And that it 
actually works, and includes the features we discuss in the paper. For 
the final version of the paper, we will provide a properly documented 
and commented version of this same codebase. On acceptance of the paper 
(at EGSR, or later elsewhere), the code will also be open sourced as a 
reference solution, in a fashion similar to smallUPBP. 



USAGE:
======

The included README_forUPBP file contains instructions for compiling 
SmallUPBP, which did not change with our modification with the exception 
of the project files being configured for Visual Studio 2015 and 
SmallUPBP project and solution being renamed to PolarisedUPBP. 


The algorithms that were modified are PT, VCM (which includes BPT), 
Volumetric PT and Volumetric BPT. UPBP itself was not made 
polarisation-capable and is disabled. 

In order to switch between the different configurations with relation to 
polarisation, use the following command line switches:
    -np   non-polarising (default)
    -p    polarising -- naive implementation
    -op   polarising -- optimised implementation
For further information about possible command line options, consult the
executable itself using the command line option "-h". 

The "scenes" directory contains the scene files and batch files for 
generating the results.
