ScanTo3D | OpalAi vs Immersity (formerly LeiaPix Converter)

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.

Immersity, formerly LeiaPix Converter, turns flat photos and videos into depth animations you can view on a normal screen or XR headset. You upload a 2D file, the Neural Depth Engine builds a depth map, and you export formats like side-by-side 3D, depth maps, spatial video for Apple Vision Pro, or animated Immersive Motion clips.

Generic 3D photo apps often stop at a single parallax wiggle. Immersity separates foreground and background into distinct layers with Neural Depth Rendering 4.0, which fills in obscured details when you pan or zoom the viewpoint. It also converts video, not just stills, with export options up to 4K on paid plans.

Creators, marketers, and XR hobbyists use it for social clips, travel footage, and stereoscopic content without building depth maps by hand. The free tier allows unlimited watermarked conversions up to 720p; paid image plans start at $4.99 per month for 500 credits and 4K output without watermarks.
