%description
|
||||
BCD allows to denoise images rendered with Monte Carlo path tracing and
|
||||
provided in the form of their samples statistics (average, distribution
|
||||
and covariance of per-pixel color samples). BCD can run in CPU (e.g.,
|
||||
renderfarm) or GPU (e.g., desktop) mode. It can be integrated as a library
|
||||
to any Monte Carlo renderer, using the provided sample accumulator to
|
||||
interface the Monte Carlo simulation with the BCD internals, and comes
|
||||
with a graphics user interface for designing interactively the denoising
|
||||
parameters, which can be saved in JSON format and later reused in batch.
|
||||
|
||||
BCD has been designed for easy integration and low invasiveness in the
|
||||
host renderer, in a high spp context (production rendering). There are
|
||||
at least three ways to integrate BCD in a rendering pipeline, by either:
|
||||
|
||||
* Dumping all samples in a raw file, using the raw2bcd tool to generate
|
||||
the rendering statistics from this file and then running the BCD using
|
||||
the CLI tool.
|
||||
|
||||
* Exporting the mandatory statistics from the rendering loop in EXR
|
||||
format and running the BCD CLI tool to obtain a denoised image.
|
||||
|
||||
* Directly integrating the BCD library into the renderer, using the
|
||||
sample accumulator to post samples to BCD during the path tracing and
|
||||
denoising the accumulated values after rendering using the library.
