X3D — Interchange Cube
A 10 mm cube as X3D — the XML successor to VRML for web and interchange 3D. For testing X3D parsers and VRML↔X3D conversion.

What is a .x3d file?
X3D (.x3d) is the XML-based successor to VRML — an ISO standard for interactive 3D scenes with geometry, appearance, animation, and scripting. It is used in web 3D, scientific visualization, and archival.
How to use this file
Use an example .x3d file to test X3D parsers, XML 3D tooling, and X3D-to-glTF conversion.
How to use this file for testing
“X3D — Interchange Cube” is a deterministic Novus Examples fixture for Conversion testing. The same content exported across many formats and linked as a group, so you can convert one and diff against the expected twin.
Documented properties for this file: X3D 3.3 (Interchange). Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
3D and CAD fixtures carry one small, documented solid or scene. Convert and inspect against the known geometry, units, and structure; format twins let you diff interchange fidelity, and the 3D viewer previews the actual mesh.
