在supermap for webGL 2023 中，采用前端js自定义水面区域，并设置水纹，在原生Cesium1.81代码里面，水纹正常，使用SuperMap iClient3D 11i (2023) beta for Cesium，水纹错乱，水纹实现代码如下：
function applyWaterMaterial(primitive, scene) {
primitive.appearance.material = new Cesium.Material({
fabric: {
type: 'Water',
uniforms: {
baseWaterColor: new Cesium.Color(64 / 255.0, 157 / 255.0, 253 / 255.0, 0.5),
normalMap: "images/waterNormals.jpg",
frequency: 1000.0,
animationSpeed: 0.01,
amplitude: 10,
specularIntensity: 10
}
}
});
}
var worldRectangle = viewer.scene.primitives.add(new Cesium.Primitive({
geometryInstances : new Cesium.GeometryInstance({
geometry : new Cesium.PolygonGeometry({
polygonHierarchy : new Cesium.PolygonHierarchy(
Cesium.Cartesian3.fromDegreesArray([114.2782783691, 30.5551370447,
114.2849717217, 30.5664644888, 114.2933813186, 30.5782210028, 114.3054808407, 30.5974433323,

])
),
vertexFormat : Cesium.EllipsoidSurfaceAppearance.VERTEX_FORMAT,
height:3
})
}),
appearance: new Cesium.EllipsoidSurfaceAppearance({
aboveGround: true
}),
show: true
}));
applyWaterMaterial(worldRectangle, scene);
纹理错乱效果：
