LogInThe new version improves the preservation of fine detail in denoised images and adds support for denoising Albedo and Normal Maps.
Intel has released an update to their open-source library of high-performance denoising filters for images rendered with ray tracing Open Image Denoise. The software is used by Blender’s Cycles renderer, Unity, V-Ray, and many other tools.
Here is the full list of changes:
- Improved fine detail preservation
- Added the cleanAux filter parameter for further improving quality when the auxiliary feature (Albedo, Normal) images are noise-free
- Added support for denoising auxiliary feature images, which can be used together with the new cleanAux parameter for improving quality when the auxiliary images are noisy
- Normals are expected to be in the [-1, 1] range (but still do not have to be normalized)
- Added the oidnUpdateFilterData function which must be called when the contents of an opaque data parameter bound to a filter have been changed after committing the filter
- Added the oidnRemoveFilterImage and oidnRemoveFilterData functions for removing the previously set image and opaque data parameters of filters
- Reduced the overhead of oidnCommitFilter to zero in some cases
- Reduced filter memory consumption by about 35%
- Reduced total memory consumption significantly when using multiple filters that belong to the same device
- Reduced the default maximum memory consumption to 3000 MB
- Added the OIDN_FILTER_RT and OIDN_FILTER_RTLIGHTMAP CMake options for excluding the trained filter weights from the build to significantly decrease its size
- Fixed detection of static TBB builds on Windows
- Fixed compile error when using future glibc versions
- Added oidnBenchmark option for setting custom resolutions
- Upgraded to oneTBB 2021.2.0 in the official binaries
