AI 3D Modeling Comparison

Marble vs. Polycam

At a glance

At a glance

Marble

Best for

Best for teams building explorable 3D environments for previsualisation, virtual production or games.

  • Freelancers
  • Small and mid-sized
  • Enterprise

Polycam

Best for

Best for teams that need real objects, sites and interiors captured as measurable 3D models rather than generated from a prompt.

  • Freelancers
  • Small and mid-sized
  • Enterprise

Cataleo does not name a winner. Both statements come from the vendors themselves.

Full Comparison

Criterion Marble Polycam
Starting price Not stated Free tier; Basic from $12.50 / user / month Basic is $150 per year or $30 billed monthly. Business is $400 per user and year, $33 per user and month billed annually. Enterprise is $1,200 per seat and year with a minimum of three seats.
Free trial Free plan with up to 4 world generations Free tier
Output Explorable 3D worlds as Gaussian splats, meshes or video 3D models, Gaussian splats and 2D and 3D floor plans from LiDAR, photos, drone footage or a single image
API Yes Yes, a content management API on the Enterprise plan
What it makes Explorable 3D worlds as Gaussian splats, meshes or video 3D models of objects and spaces from LiDAR, photos, drone footage or a single 2D image, plus Gaussian splats and 2D and 3D floor plans
Detail and topology Splats at about 2M or 500k; meshes at about 600k triangles textured, 1M vertex-coloured, plus a 100-200k collider mesh Four photogrammetry processing levels, Fast (Optimized), Medium, Full and Raw; Raw keeps the highest detail with multiple 8K textures, while Optimized and Medium trade some resolution for real-time and mobile use and add ambient occlusion and normal maps. A Remesh tool and a simplification percentage set the polygon count and texture maps before export
Rigging and textures No rigging or animation, the output is an environment rather than a character. Collider mesh export is included from the Standard plan, textured GLB export requires Pro AI Texture Generator for custom surfaces
Speed High-quality mesh export takes up to an hour, limited to 4 requests per hour Set by the processing level chosen: polygon count and texture resolution drive processing time, and Polycam advises dropping from Raw to Full when a large scan processes too slowly
Export and pipeline fit SPZ and PLY splats, GLB meshes, 360 panorama PNG; guides for Unreal Engine, Unity, Blender and Houdini More than a dozen export formats for Blender, SketchUp, Unity and Unreal; the free plan exports GLTF only, and mesh and point cloud formats need a paid plan
Commercial use Commercial rights included from the Pro plan Yes. The terms of service state that Polycam claims no ownership of the models a user creates, and that models generated with the service may be copied, modified, published, distributed, sublicensed or commercialised as long as Polycam is credited. No distinction is drawn there between free and paid accounts
Deployment Cloud (SaaS), Browser-based Cloud (SaaS), Browser-based
Support Email helpdesk, Community forum Not stated
Onboarding Documentation and knowledge base Documentation and knowledge base
Company size Freelancers, Small and mid-sized, Enterprise Freelancers, Small and mid-sized, Enterprise

The trade-offs

Strengths and Limitations

Marble

Strengths

  • Generates navigable worlds rather than single objects
  • Takes text, images, video, 360 panoramas or a coarse 3D layout as input
  • Chisel blocks out world structure in 3D before generating
  • Worlds can be expanded and composed into larger spaces
  • Documented export routes into Unreal Engine, Unity, Blender and Houdini

Limitations

  • Commercial rights only from the Pro plan upwards
  • Free plan covers only four world generations
  • High-quality mesh export takes up to an hour and is rate limited
  • High-quality meshes can only be generated on worlds you own

Polycam

Strengths

  • Covers LiDAR, photo, drone and 360 capture alongside AI image-to-3D in one product
  • Free plan with GLTF export and public link sharing
  • Floor plans, advanced measurement and virtual walkthroughs from the Business plan

Limitations

  • The free plan limits captures and exports GLTF only
  • Point cloud export, floor plans and the API sit on the higher plans
  • Enterprise requires a minimum of three seats

Plans
