CloudCompare
An open-source 3D point-cloud and mesh tool with registration, segmentation, distance analysis, filtering, and broad scan-format support.
Why use it
Photogrammetry and laser-scan pipelines can clean data, align captures, and quantify reconstruction error.
Where it fits
Use art, animation, audio, levels, and narrative to make the game easy to read and its world convincing.
What to check
It targets measurement and processing rather than game-asset polish; dense data consumes substantial memory and final topology and materials need a DCC.
