API Reference

Unlimited Scale

No fixed point-count limit. Load, render and explore Gaussian scenes with hundreds of millions of points and beyond.

7 Import Formats

LiSplat · XML · PLY · KSPLAT · SOG · SPLAT · SPZ.

Point-Level Editing

Select points in multiple ways, then delete, clone, separate, recolor, crop or slice them.

Measure · Annotate · Navigate

Measure coordinates, distances and areas; add multimedia annotations and jump between scenes to record and navigate spatial information.

Generate Collisions

Generate collision geometry in UE after loading Gaussian data. No prebuilt collision file is required—generate it and start walking.

Unreal Rendering & Performance

Choose rendering and lighting modes, reduce aliasing and flicker, and tune performance to balance visual quality with smooth playback.

Camera Paths & Video

Edit camera paths and timeline flythroughs, then export video ready to share.

OpenXR VR Delivery

Walk or fly, then build a standalone Win64 VR application in one step. Validated on PICO and Meta Quest headsets.
