glTF Morph Targets — Eight Simultaneous Targets (GLB)
Eight POSITION morph targets on one primitive — bumps arranged around a circle, so every active weight is visible independently. Eight is where many real-time renderers stop supporting extra targets; this is the fixture that says whether yours does.
Specifications
- Format
- glTF 2.0 binary (GLB)
- Morph Targets
- 8
- Vertices
- 289
- Target Attributes
- POSITION
- Note
- at the common eight-weight renderer limit
Testing contract
Expected to pass- Scenario
- Set all eight weights to 0.6 at once and count the visible bumps.
- Expected result
- Eight distinct bumps appear; a renderer capped at four silently drops the last four instead of reporting an error.
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
“glTF Morph Targets — Eight Simultaneous Targets (GLB)” is a deterministic Novus Examples fixture for Conversion testing, Mesh processing QA. 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: glTF 2.0 binary (GLB). 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.
