Unbiased Diffuse Illumination:
------------------------------
- UberPOV allows to disable the caching of radiosity samples, by
using the
following syntax in the global radiosity block:
no_cache [BOOL]
It also changes the way the secondary ray directions are chosen, and
effectively turns the radiosity algorithm into a purely stochastic
unbiased
algorithm to compute diffuse illumination.
Most radiosity settings are without effect in this mode, except for the
following:
adc_bailout FLOAT
brightness FLOAT
brilliance BOOL
count FLOAT
gray_threshold FLOAT
media BOOL
normal BOOL
recursion_limit INT
subsurface BOOL
The current implementation does not translate classic radiosity
settings
into useful parameters for this mode of operation; it is therefore
highly
recommended to use a much lower setting for the "count" parameter than
typical with standard radiosity.
This syntax extension can be tested for using the #patch directive or
patch() function with the patch name "upov-radiosity-no_cache"; the
current
implementation is version 0.1.

Commit 21cc3c6 on 2014-07-24 by Christoph Lipka
Add support for stochastic diffuse computations.
Specifying `no_cache` in the global radiosity block will disable
caching of radiosity samples,
and use a more random algorithm to generate secondary ray
directions, effectively using the
radiosity code for straightforward stochastic computation of
diffuse illumination.
