LCC for Unity Downloads

LCC Unity SDK is an industrial-grade 3DGS development kit for high-performance rendering of scenes from object scale to city scale. It supports LCC2, PLY, SPLAT, SPZ, SOG, and KSPLAT formats, ships to Windows, Ubuntu, macOS, iOS, Android, and VR, and covers real-time hybrid rendering of single and multiple scenes — with industrial- and game-grade features including collision, highlighting, clipping, relighting, shadows, projection decals, and video-stream fusion.
