PartCrafter vs Polycam

PartCrafter is a free, open-source model that generates multiple 3D parts and objects from a single RGB image. It can handle individual objects and complex scenes, producing distinct meshes with meaningful part structure without requiring a pre-segmented image. Its architecture represents parts with disentangled latent tokens and uses hierarchical attention to pass information within and across parts. Local inference scripts can remove backgrounds and optionally apply style transfer to adapt real-world photos toward the rendered-image domain used for training. An optional vision-language feature can suggest the number of parts; Gemini is the default provider, and the provider architecture can be extended. Pretrained object-level and scene-level weights are hosted on Hugging Face. Installation is from the GitHub repository in a Python environment, and inference requires a CUDA-enabled GPU with at least 8 GB of VRAM. The linked Hugging Face demo is paused, though its page says users can ask the authors to restart it. The repository lists an MIT license and provides the software as-is, without warranty.

Polycam is AI reality capture software for professionals who document, measure and design. It uses AI-assisted photogrammetry and LiDAR to capture spaces, construction sites, facilities, products and materials in 3D, and it can create shareable 3D object models. Users can generate customizable 2D floor plans; paid plans also list instant 3D and editable 2D floor plans. Drone footage can be processed into expansive 3D models. Polycam is available on Android, iOS and web browsers, though Space Mode scanning is limited to compatible iOS devices. Listed exports include GLTF, OBJ, FBX, DAE, STL, USDZ, point cloud formats and DXF; named workflows include Blender, Unity, SketchUp and Xactimate. Free access has limited space, object and AI captures, with GLTF exports and public link sharing. Basic costs $150 a year, equivalent to $12.50 per month when billed yearly. Seven-day trials are offered with annual Basic and Business plans, but not monthly plans or Enterprise. Business is listed at $400 a year and Enterprise at $1,200 a year.
