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 |
