Release 2.2.0 (2019.08.08)

Release Notes Summary:

• Texturing: Largely improve the Texturing quality using Multi-Band Blending technique. PR
• Texturing: Support for RAW image files: Libraw update and fix its usage in OpenImageIO (fix color shift and use correct gamma). PR
• Texturing: Performance optimization by iterating over multiple output textures at the same time. PR
• Texturing: Add support for UDIM in UV mapping and use it by default. PR
• Meshing: Export the dense point cloud in Alembic and computes the points colors PR.
• Meshing: New option to export the full raw dense point cloud in the Meshing software (with all 3D points candidates before cut and filtering). PR
• Meshing: Adds an option to export color data per vertex and MeshFiltering correctly preserves colors. PR.
• HDR: New HDR module for the fusion of multiple LDR images with the corresponding new software LDR2HDR. It implements linear fusion as well as Camera Response Function (CRF) calibration with Robertson, Debevec or Grossberg methods. PR
• PrepareDenseScene: Add experimental option to correct Exposure Values (EV) of input images to uniformize dataset exposures. PR

Release 2.1.0 (2019/01/30)

Release Notes Summary:

• More complete sensor database and better matching as well as explicit status for lens initialization
• Add support for rig of cameras. This enables to add more contraints if you make acquisition with multiple synchronized devices.
• Support for reconstruction with projected light patterns and texturing with another images set.
• Better estimation of the space to reconstruct to limit the reconstruction zone. This avoid to reconstruct low quality and useless areas around the main object/environment.
• New option to directly mesh the SfM results. This provides a quick solution to get a draft mesh (without cuda requirement).
• Reduce IO and intermediate files in MVS part of the pipeline.

See Changelog for more details.
