Feature Tests

Models meant to easily illustrate and test specific features of the core specification.

Model	Screenshot	Description
Alpha Blend Mode Test		Tests alpha modes and settings.
Boom Box With Axes		Shows X, Y, and Z axis default orientations.
Metal Rough Spheres		Tests various metal and roughness values (texture mapped).
Metal Rough Spheres (Textureless)		Tests various metal and roughness values (textureless).
Morph Primitives Test		Tests a morph target on multiple primitives.
Morph Stress Test		Tests up to 8 morph targets.
Multi UV Test		Tests a second set of texture coordinates.
Negative Scale Test		Tests what happens when geometry is mirrored.
Normal Tangent Test		Tests an engine's ability to automatically generate tangent vectors for a normal map.
Normal Tangent Mirror Test		Tests an engine's ability to load supplied tangent vectors for a normal map.
Orientation Test		Tests node translations and rotations.
Recursive Skeletons		Tests unusual skinning cases with reused meshes and recursive skeletons.
Texture Coordinate Test		Shows how XYZ and UV positions relate to displayed geometry.
Texture Linear Interpolation Test		Tests that linear texture interpolation is performed on linear values, i.e. after sRGB decoding.
Texture Settings Test		Tests single/double-sided and various texturing modes.
Vertex Color Test		Tests if vertex colors are supported.

Minimal Tests

Minimal models testing very narrow pieces of the core specification.

Model	Screenshot	Description
Triangle Without Indices		The simplest possible glTF asset: A single scene with a single node and a single mesh with a single mesh.primitive with a single triangle with a single attribute, without indices and without a material
Triangle		A very simple glTF asset: The basic structure is the same as in Triangle Without Indices, but here, the mesh.primitive describes an indexed geometry
Animated Triangle		This sample is similar to the Triangle, but the node has a rotation property that is modified with a simple animation
Animated Morph Cube		Demonstrates a simple cube with two simple morph targets and an animation that transitions between them both.
Animated Morph Sphere		This sample is similar to the Animated Morph Cube, but the two morph targets move many more vertices and are more extreme than with the cube.
Simple Meshes		A simple scene with two nodes, both containing the same mesh, namely a mesh with a single mesh.primitive with a single indexed triangle with multiple attributes (positions, normals and texture coordinates), but without a material
Multiple Scenes		A simple glTF asset with two scenes. Each scene consists of one node with one mesh. For the first scene, the mesh is a triangle. For the second scene, the mesh is a square. The default scene is set to 1 by the scene property, so viewers should initially show the scene containing the square.
Simple Morph		A triangle with a morph animation applied
Simple Sparse Accessor		A simple mesh that uses sparse accessors
Simple Skin		A simple example of vertex skinning in glTF
Cameras		A sample with two different camera objects
Interpolation Test		A sample with three different animation interpolations
Unicode Test		A sample with Unicode characters in file, material, and mesh names

Extensions
