ShowGeometryInstanceAttribute

var instance = new GeometryInstance({
  geometry : new BoxGeometry({
    vertexFormat : VertexFormat.POSITION_AND_NORMAL,
    dimensions : new Cartesian3(1000000.0, 1000000.0, 500000.0)
  }),
  modelMatrix : Matrix4.multiplyByTranslation(Transforms.eastNorthUpToFixedFrame(
    ellipsoid.cartographicToCartesian(Cartographic.fromDegrees(-75.59777, 40.03883))), new Cartesian3(0.0, 0.0, 1000000.0)),
  id : 'box',

  }
});

Members

<readonly> componentDatatype :ComponentDatatype

The datatype of each component in the attribute, e.g., individual elements in ShowGeometryInstanceAttribute#value.

Default Value:

• ComponentDatatype.UNSIGNED_BYTE

<readonly> componentsPerAttribute :Number

The number of components in the attributes, i.e., ShowGeometryInstanceAttribute#value.

Default Value:

• 1

<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

value :Uint8Array

The values for the attributes stored in a typed array.

Default Value:

• [1.0]

Methods

<static> toValue

Converts a boolean show to a typed array that can be used to assign a show attribute.

Parameters:

Name	Type	Argument	Description
show	Boolean		The show value.
result	Uint8Array	<optional>	The array to store the result in, if undefined a new instance will be created.

Throws:

DeveloperError : show is required.

Returns:

Uint8Array The modified result parameter or a new instance if result was undefined.

Example

var attributes = primitive.getGeometryInstanceAttributes('an id');
attributes.show = ShowGeometryInstanceAttribute.toValue(true, attributes.show);
