Standard

Standard models demonstrating multiple features of the core specification.

Model Screenshot Description
Box One mesh and one material. Start with this.
Box Interleaved Box example with interleaved position and normal attributes.
Box Textured Box with one texture. Start with this to test textures.
Box Textured NPOT Box with a non-power-of-2 (NPOT) texture. Not all implementations support NPOT textures.
Box With Spaces Box with URI-encoded spaces in the texture names used by a simple PBR material.
Box Vertex Colors Box with vertex colors applied.
Cube A cube with non-smoothed faces.
Animated Cube Same as previous cube having a linear rotation animation.
Duck The COLLADA duck. One texture.
2 Cylinder Engine Small CAD data set, including hierarchy.
Reciprocating Saw Small CAD data set, including hierarchy.
Gearbox Assy Medium-sized CAD data set, including hierarchy.
Buggy Medium-sized CAD data set, including hierarchy
Box Animated Rotation and Translation Animations. Start with this to test animations.
Cesium Milk Truck Textured. Multiple nodes/meshes. Animations.
Rigged Simple Animations. Skins. Start with this to test skinning.

BrainStem Animations. Skins.
Fox Multiple animations cycles: Survey, Walk, Run.
Virtual City Textured. Animations.
Sponza Building interior, often used to test lighting.
Two Sided Plane A plane having the two sided material parameter enabled.

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
