What It Does

RealityScan is more productized than raw COLMAP. It helps users capture objects and environments with guided workflows, then process them through Epic’s scanning stack.

For 3DGS users, it belongs in the alignment and asset-preparation conversation: especially when the goal is a usable 3D asset rather than a research dataset.

How To Use It In 3DGS

Use the mobile app or desktop flow to capture the subject with strong overlap.
Process the scan and inspect whether the asset captures the intended surfaces.
Export or move the result into the downstream toolchain supported by your project.
Use a 3DGS viewer or editor if you produce or convert a splat asset later in the pipeline.

Things To Watch

App-guided capture still needs good lighting and stable coverage.
Check export formats before committing to a downstream 3DGS or game-engine workflow.
Product features can change, so verify the current RealityScan path for your platform.

RealityScan vs RealityScan Mobile

RealityCapture was rebranded as RealityScan on desktop, with RealityScan 2.0 adding AI masking, smarter alignment, quality analysis, and aerial LiDAR support.
RealityScan Mobile is the phone/tablet companion for fast guided captures and Sketchfab publishing.
For precise survey, VFX, or large-scale work, the desktop product is the more relevant tool; for quick object capture, start with Mobile.
