VolumeForge uses open-source software and links to materials hosted by third parties. Each component remains under its own licence.
Last updated: 29 October 2026.
Download the bundled third-party copyright notices and licence texts. This includes the installed Three.js, fflate, Lucide (including Feather), Comlink, PlaneGCS, Astro, Starlight, and Pagefind notices. Additional OCCT terms and source links are described below. The licences grant rights directly from their respective authors; the VolumeForge terms do not override them.
Browser editor
Section titled “Browser editor”| Software component | Licence |
|---|---|
| Three.js 0.181.2 | MIT |
| fflate 0.8.3 | MIT |
| Lucide 1.48.0 | ISC; Feather-derived icons: MIT |
| Comlink 4.4.2 | Apache-2.0 |
@salusoft89/planegcs 1.2.0 | GNU LGPL; the package includes the LGPL 2.1 text. Its npm metadata declares LGPL-2.0-or-later; preserve the component’s source-file notices. |
occt-wasm wrapper 3.8.0 | MIT OR Apache-2.0 |
| Open CASCADE Technology (OCCT) WebAssembly | LGPL-2.1 with the Open CASCADE exception |
The occt-wasm tooling and wrapper licence is separate from the compiled OCCT WebAssembly licence. The installed package identifies its OCCT base as V8.0.0.p1 and its compiled output as LGPL-2.1-only. The Open CASCADE exception supplements the OCCT licence; it is not a replacement for the LGPL.
Upstream source and build information are available from the PlaneGCS project and occt-wasm version 3.8.0. Read the GNU LGPL v2.1 and the linked Open CASCADE exception for their terms. These upstream references identify the projects; they are not a claim that a release-specific corresponding-source archive is hosted by VolumeForge.
The LGPL components are supplied without warranty under their licences. You retain the rights those licences grant, including modification and reverse engineering for debugging modifications where applicable. The editor loads its geometry and constraint-solving WebAssembly as separate assets. Any redistribution must preserve applicable notices and meet the relevant source and modification/replacement requirements.

Section titled “Documentation site”| Software component | Licence |
