*
    *
  • Experimental features must have high unit test coverage like any other feature.
    • *
  • Experimental features are intended for large features where there is benefit of merging some of the code sooner (e.g. to avoid long-running staging branches)
    • *
  • Experimental flags should be short-lived. Make it clear in the PR what it would take to promote the feature to a regular feature.
    • *
  • To avoid cluttering the code, check the flag in as few places as possible. Ideally this would be a single place.

* Note: for models with compressed textures using the KHR_texture_basisu extension, we recommend power of 2 textures in both dimensions * for maximum compatibility. This is because some samplers require power of 2 textures ({@link https://developer.mozilla.org/en-US/docs/Web/API/WebGL_API/Tutorial/Using_textures_in_WebGL|Using textures in WebGL}) * and KHR_texture_basisu requires multiple of 4 dimensions ({@link https://github.com/KhronosGroup/glTF/blob/master/extensions/2.0/Khronos/KHR_texture_basisu/README.md#additional-requirements|KHR_texture_basisu additional requirements}). *

Animation widget * *

* The Animation widget provides buttons for play, pause, and reverse, along with the * current time and date, surrounded by a "shuttle ring" for controlling the speed of animation. *

* The "shuttle ring" concept is borrowed from video editing, where typically a * "jog wheel" can be rotated to move past individual animation frames very slowly, and * a surrounding shuttle ring can be twisted to control direction and speed of fast playback. * Cesium typically treats time as continuous (not broken into pre-defined animation frames), * so this widget offers no jog wheel.

This mode is not available in {@link ClockRange.CLAMPED} or * {@link ClockRange.LOOP_STOP} mode if the current time is outside of {@link Clock}'s startTime and endTime. * @example * // In HTML head, include a link to Animation.css stylesheet, * // and in the body, include:
