Reference control- Scenario
- Exercise Mesh Repair GT — Tube Watertight (GLB) in its repair workflow. Watertight tube mesh — the intended result for a mesh-repair / hole-filling tool applied to the broken member of this group.
- Expected result
- GLB version=2, declared bytes=14300, actual bytes=14300; meshes=1, nodes=1, materials=0, animations=0, accessors=4. Declared feature checks: triangles=112; role=watertight ground truth; shape=tube.
What is a .glb file?
GLB is the binary form of glTF, packaging 3D scene geometry, materials, textures, animations, and node hierarchy into a single self-contained file. It is optimized for efficient runtime loading and is often called the JPEG of 3D. It is widely used in web, AR, and real-time 3D applications.
How to use this file
Use an example GLB to test glTF loaders, embedded-texture and animation handling, and real-time rendering pipelines in web or game engines.
How to use this file for testing
“Mesh Repair GT — Tube Watertight (GLB)” is a deterministic Novus Examples fixture for Mesh repair testing, Mesh processing QA. A watertight mesh paired with a deliberately broken twin (holes, missing faces, open ends), the input and intended result for a mesh-repair / hole-filling tool.
Documented properties for this file: watertight ground truth · glTF 2.0 binary. 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.
Code examples
import trimesh # pip install trimesh
mesh = trimesh.load("tube-watertight.glb")

- glbGLB — Clean Reference CubeThe clean reference cube as a GLB, so the same baseline is available to glTF tooling and to the site's 3D preview. Identical topology to the OBJ twin in this group.
- glbGLB — Duplicate Vertices, Split SeamThe duplicated-corner cube as a GLB. Because glTF stores every attribute per vertex, the duplication doubles the position and normal buffers for a shape that needs eight corners — the cheapest optimisation an asset pipeline can make, and the one this fixture measures.
