材質設置

uniforms: {
        color: new Cesium.Color(1.0, 1.0, 1.0, 1.0),
    image: './images/yunceng.jpg'
},
components: {
    alpha:
        'texture2D(image, fract(repeat * materialInput.st)).r * color.a',
        diffuse: 'vec3(1.0)'
}

通過postUpdate更新heading

Cesium.Transforms.headingPitchRollToFixedFrame(
    new Cesium.Cartesian3(),
    new Cesium.HeadingPitchRoll(Cesium.Math.toRadians(heading), 0, 0)
)
