ObjectSymbol3DLayer

ObjectSymbol3DLayer is used to render Point geometries using a volumetric 3D shape (e.g., a sphere or cylinder) with a Symbol3D in a SceneView.

Properties

Property	Details
anchor	The positioning of the object relative to the geometry. Valid values: bottom center origin relative top
anchorPosition[]	When anchor equals relative, this property specifies the positioning of the object relative to the geometry as a fraction of the symbol layer's bounding box. Otherwise it is ignored.
castShadows	Boolean to control the shadow casting behaviour of the rendered geometries.
depth	Object depth in meters, positive only
enable
heading	Rotation angle around Z axis in degrees. At 0 degrees, the model points in the direction of the Y-axis. Positive values indicate clockwise rotation (when looked at from the top). Detailed description.
height	Object height in meters, positive only
material	The material used to shade the geometry.
resource	The primitive shape (primitive) or external 3D model (href) used to visualize the points.
roll	Rotation angle around Y axis in degrees. At 0 degrees, the model is level. A positive value lifts the left part and lowers the right part of the model. Detailed description.
tilt	Rotation angle around X axis in degrees. At 0 degrees, the model is level. A positive value lifts the front and lowers the back of the model. Detailed description.
type	Specifies the type of symbol used. Valid value of this property Object
width	Object width in meters, positive only

Object symbol layer with relative anchor Example

Places a diamond symbol such that its Southern tip coincides with the point geometry (assuming ENU coordinates).

{
  "type": "Object",
  "resource": {
    "primitive": "diamond"
  },
  "width": 10000,
  "anchor": "relative",
  "anchorPosition": [
    0,
