new Cesium.ColorGeometryInstanceAttribute(red, green, blue, alpha)

Value and type information for per-instance geometry color.
Name Type Default Description
red Number 1.0 optional The red component.
green Number 1.0 optional The green component.
blue Number 1.0 optional The blue component.
alpha Number 1.0 optional The alpha component.
const instance = new Cesium.GeometryInstance({
  geometry : Cesium.BoxGeometry.fromDimensions({
    dimensions : new Cesium.Cartesian3(1000000.0, 1000000.0, 500000.0)
  modelMatrix : Cesium.Matrix4.multiplyByTranslation(Cesium.Transforms.eastNorthUpToFixedFrame(
    Cesium.Cartesian3.fromDegrees(0.0, 0.0)), new Cesium.Cartesian3(0.0, 0.0, 1000000.0), new Cesium.Matrix4()),
  id : 'box',
  attributes : {
    color : new Cesium.ColorGeometryInstanceAttribute(red, green, blue, alpha)


The datatype of each component in the attribute, e.g., individual elements in ColorGeometryInstanceAttribute#value.
Default Value: ComponentDatatype.UNSIGNED_BYTE

readonly componentsPerAttribute : Number

The number of components in the attributes, i.e., ColorGeometryInstanceAttribute#value.
Default Value: 4

readonly normalize : Boolean

When true and componentDatatype is an integer format, indicate that the components should be mapped to the range [0, 1] (unsigned) or [-1, 1] (signed) when they are accessed as floating-point for rendering.
Default Value: true
The values for the attributes stored in a typed array.
Default Value: [255, 255, 255, 255]


static Cesium.ColorGeometryInstanceAttribute.equals(left, right)Boolean

Compares the provided ColorGeometryInstanceAttributes and returns true if they are equal, false otherwise.
Name Type Description
left ColorGeometryInstanceAttribute optional The first ColorGeometryInstanceAttribute.
right ColorGeometryInstanceAttribute optional The second ColorGeometryInstanceAttribute.
true if left and right are equal, false otherwise.

static Cesium.ColorGeometryInstanceAttribute.fromColor(color)ColorGeometryInstanceAttribute

Creates a new ColorGeometryInstanceAttribute instance given the provided Color.
Name Type Description
color Color The color.
The new ColorGeometryInstanceAttribute instance.
const instance = new Cesium.GeometryInstance({
  geometry : geometry,
  attributes : {
    color : Cesium.ColorGeometryInstanceAttribute.fromColor(Cesium.Color.CORNFLOWERBLUE),

static Cesium.ColorGeometryInstanceAttribute.toValue(color, result)Uint8Array

Converts a color to a typed array that can be used to assign a color attribute.
Name Type Description
color Color The color.
result Uint8Array optional The array to store the result in, if undefined a new instance will be created.
The modified result parameter or a new instance if result was undefined.
const attributes = primitive.getGeometryInstanceAttributes('an id');
attributes.color = Cesium.ColorGeometryInstanceAttribute.toValue(Cesium.Color.AQUA, attributes.color);
