new 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.
var instance = new Cesium.GeometryInstance({
  geometry : new Cesium.BoxGeometry({
    dimensions : new Cesium.Cartesian3(1000000.0, 1000000.0, 500000.0)
  modelMatrix : Cesium.Matrix4.multiplyByTranslation(Cesium.Transforms.eastNorthUpToFixedFrame(

  attributes : {
    color : new Cesium.ColorGeometryInstanceAttribute(red, green, blue, alpha)


readonlycomponentDatatype :ComponentDatatype

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

readonlycomponentsPerAttribute :Number

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

readonlynormalize :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

value :Uint8Array

The values for the attributes stored in a typed array.
Default Value: [255, 255, 255, 255]



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

staticColorGeometryInstanceAttribute.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.
var attributes = primitive.getGeometryInstanceAttributes('an id');
attributes.color = Cesium.ColorGeometryInstanceAttribute.toValue(Cesium.Color.AQUA, attributes.color);
