Improvements
- Load the mapper database lazily instead of at GUI startup, avoiding a redundant database read when opening the GUI or a project.
- Tint UI icons to the palette for improved dark theme legibility.
- Show image/point viewer metadata when the source images are missing on disk.
- Fail the Caspar build early with a clear error on CUDA architectures below 7.0.
Bug Fixes
- Fix feature matching slowdown (~4-6x) caused by a process-global OpenMP
critical section in
RANSAC/LORANSAC. - Fix rescaling of already-undistorted images when
max_image_sizeis provided. - Fix missing SVG icons in the distributed Windows binaries.
- Fix Caspar CUDA build with MSVC forced includes.
- Fix glog color support version detection.
- Fix typos in a user-facing help string and the FAQ.
Breaking Changes
- Renamed the misspelled pycolmap enum
GPSTransfromEllipsoidtoGPSTransformEllipsoid. The old name has been removed without a backwards-compatible alias; update any references accordingly.
