Members
readonly componentDatatype : ComponentDatatype
The datatype of each component in the attribute, e.g., individual elements in
ColorGeometryInstanceAttribute#value.
-
Default Value:
ComponentDatatype.UNSIGNED_BYTE
属性中的组件数, i.e .,
ColorGeometryInstanceAttribute#value .
-
Default Value:
4
当 NT 0 true NT 1 和 NT 2 组件Datatype NT 3 是一个整数格式时,
indicate that the components should be mapped to the range [0, 1] (unsigned)
或[-1, 1] (署名),当它们作为浮点进行渲染时.
-
Default Value:
true
输入数组中存储属性的值 .
-
Default Value:
[255, 255, 255, 255]
Methods
比较提供的颜色图形属性和返回
-NT+0+Treal NT+1+,如果两者是相等的, NT+2+false NT+3+否则.
| Name | Type | Description |
|---|---|---|
left |
ColorGeometryInstanceAttribute | optional 首个色彩测量InstanceAttize. |
right |
ColorGeometryInstanceAttribute | optional 第二色相几何内存属性. |
Returns:
如果左右对等, 则使用 NT 0 true NT 1 , 否则使用 NT 2 false NT 3 .
static Cesium.ColorGeometryInstanceAttribute.fromColor(color) → ColorGeometryInstanceAttribute
Creates a new
ColorGeometryInstanceAttribute instance given the provided Color.
| Name | Type | Description |
|---|---|---|
color |
Color | The color. |
Returns:
The new
ColorGeometryInstanceAttribute instance.
Example:
const instance = new Cesium.GeometryInstance({
geometry : geometry,
attributes : {
color : Cesium.ColorGeometryInstanceAttribute.fromColor(Cesium.Color.CORNFLOWERBLUE),
}
});
将一个颜色转换成可以用来指定颜色属性的打字数组.
| Name | Type | Description |
|---|---|---|
color |
Color | The color. |
result |
Uint8Array | optional 如果创建未定义的新实例, 将存储结果的数组 . |
Returns:
如果结果未定义, 修改后的结果参数或新实例 .
Example:
const attributes = primitive.getGeometryInstanceAttributes('an id');
attributes.color = Cesium.ColorGeometryInstanceAttribute.toValue(Cesium.Color.AQUA, attributes.color);
