ScanTo3D | OpalAi vs DeepMotion

ScanTo3D by OpalAi is a 3D generation app for iPhone Pro and iPad Pro that turns LiDAR walkthrough scans into floor plans, point clouds, and BIM-ready models. You walk through a space with your phone, capture geometry in InstaCAD or LiDAR mode, and export digital twins in formats like OBJ, GLTF, STL, and USDZ. It targets property owners, contractors, and facility teams who need as-built documentation without hauling a dedicated scanner.

Compared to renting tripod LiDAR hardware, ScanTo3D trades equipment cost for device requirements and optional cloud processing. InstaCAD mode builds 2D floor plans and 3D CAD models in real time for spaces under 2,000 square feet, while LiDAR mode handles larger environments with no hard size cap though OpalAi recommends keeping each scan under about 5,000 square feet.

Site managers, real estate teams, and construction sales staff use it for quick floor plans, ANSI-compliant gross living area calculations, and textured 3D exports. OpalAi claims less than 1 inch of error per 30 feet and about 98% accuracy on generated floor plans and BIM objects.

DeepMotion builds 3D character animation from text prompts or reference video through a browser, with no mocap suit required. Its two products, SayMotion and Animate 3D, turn written motion descriptions or uploaded MP4, MOV, and AVI clips into exportable skeleton data for game and film pipelines. Output ships as FBX, BVH, GLB, or MP4 files you can retarget to custom characters.

Traditional motion capture needs specialized hardware and studio space. DeepMotion runs markerless full-body tracking in the cloud, so indie studios and solo animators can produce fight choreography or dance moves from a phone video. SayMotion adds generative inpainting to extend or blend motions beyond stock libraries, which stock animation sites cannot match without manual editing.

Game developers, XR artists, film students, and educators use it to prototype character motion before committing to a full rigging pass. The Free Animation Credit Program lets users earn back credits by labeling motion descriptions or correcting poses in the Rotoscope editor.
