## On this page # Test006 Last update: 16.07.2025 Animation. This example shows how to add animation to a scene. Animations involve creating samplers that describe values of properties at defined times. The ANSYSViewer interpolates the property to generate values at times that fall between the defined times. The samplers are added to the animation as channels. The channels defined which property to animate. Only some properties can be animated: - node - matrix - node - visible - material - Any value In this example the matrix property and visible property of nodes are changed along with the color value of a material. <script src="/ansys/nexus/viewer-loader.js"></script> /\* \* Copyright 2018-2021 ANSYS, Inc.
