Animate All The Things

Screenshots

Purpose

This sample model demonstrates the KHR_animation_pointer extension which allows animating most properties of a glTF file, in contrast to "regular" animation which can only animate node transforms and morph target weights. These new capabilities bring glTF on par with other powerful animation systems such as USD, Blender, Unity.

The model serves as a complex integration case to test and ensure which specific extensions and animation capabilities are available in a specific viewer.

Support
