Data handling

The documentation says files stay on the user's computer and do not leave it.Read 12 Oct 2026 · polygonal.app

Device support

The app can run on desktops, tablets, and phones; desktops and laptops are best supported.Read 12 Oct 2026 · polygonal.app

Editing and selection

The docs describe vertex selection, lasso and polygon selection, moving selections, deleting vertices, and splitting or flipping edges.Read 12 Oct 2026 · polygonal.app

Feature limitation

Remeshing and decimation require a triangle mesh, so polygon meshes may need triangulation first.Read 12 Oct 2026 · polygonal.app

Feature preservation

Detected sharp feature edges can be preserved during remeshing, decimation, and the Catmull-Clark and Loop subdivision schemes.Read 12 Oct 2026 · polygonal.app

File formats

Polygonal supports importing and exporting STL, OBJ, and OFF mesh files.Read 12 Oct 2026 · polygonal.app

Hole filling

The hole-filling filter repairs simple boundary loops, but does not support loops with non-manifold vertices.Read 12 Oct 2026 · polygonal.app

Local data and offline use

The documentation says files stay on the user's computer and that the app can be used offline after it loads.Read 12 Oct 2026 · polygonal.app

Maker and company details

The pages opened identify the product as Polygonal and provide an email contact, but do not state a maker organization, headquarters, or founding year.Read 12 Oct 2026 · polygonal.app

Mesh compatibility

Polygonal supports 2-manifold surface meshes with well-defined connectivity, but not non-manifold meshes.Read 12 Oct 2026 · polygonal.app

Mesh editing

Features include feature preservation, mesh decimation, hole filling, and smoothing.Read 12 Oct 2026 · polygonal.app

Mesh limits

Polygonal supports 2-manifold surface meshes with defined connectivity and does not support non-manifold meshes; remeshing and decimation require triangle meshes.Read 12 Oct 2026 · polygonal.app

Mesh operations

It supports triangulation, subdivision, remeshing, decimation, and importing and exporting STL, OBJ, and OFF files.Read 12 Oct 2026 · polygonal.app

Offline use

After loading, the application can be used offline.Read 12 Oct 2026 · polygonal.app

Other operations

The documentation lists triangulation and surface refinement using subdivision.Read 12 Oct 2026 · polygonal.app

Platform access

browserRead 22 Sep 2026 · polygonal.app

Pricing

The maker says Polygonal has no signup and no subscription.Read 12 Oct 2026 · polygonal.app

Remeshing

Curvature-adaptive remeshing adjusts mesh density while maintaining important surface details.Read 12 Oct 2026 · polygonal.app

Smoothing

The smoothing filter removes mesh noise using Laplacian smoothing, with uniform or cotangent weights and implicit or explicit schemes.Read 12 Oct 2026 · polygonal.app

Subdivision

Polygonal offers Loop, Quad-Triangle, and Catmull-Clark subdivision schemes; Loop requires triangle meshes and Catmull-Clark works on general polygon meshes.Read 12 Oct 2026 · polygonal.app
