PointCloudSceneLayer Class

In This Topic

Point cloud scene layers allow for fast display and consumption of large volumes of point cloud data.

Object Model

Syntax

C#
Visual Basic (Declaration)

public sealed class PointCloudSceneLayer : Layer, ArcGIS.Desktop.Core.IMetadataInfo, IMetadataSource, System.ComponentModel.INotifyPropertyChanged

Public NotInheritable Class PointCloudSceneLayer 
   Inherits Layer
   Implements ArcGIS.Desktop.Core.IMetadataInfo, IMetadataSource, System.ComponentModel.INotifyPropertyChanged

Remarks

The primary source of point cloud data is usually LAS and lidar data. Lidar surveys for terrain, buildings, forest canopy, roads, bridges, overpasses, and more can make up the point cloud data used for a point cloud scene layer.

Example

Name of PointCloudSceneLayer

var pcsl = MapView.Active.Map.GetLayersAsFlattenedList()
               .OfType<PointCloudSceneLayer>().FirstOrDefault();
var scenelayerName = pcsl?.Name;

Edit Color Modulation

//Must be called on the MCT
//var pcsl = ...;
var def = pcsl.GetDefinition() as CIMPointCloudLayer;
//Get the ColorModulation off the renderer
var modulation = def.Renderer.ColorModulation;
if (modulation == null)
  modulation = new CIMColorModulationInfo();
//Set the minimum and maximum intensity as needed
modulation.MinValue = 0;
modulation.MaxValue = 100.0;
//apply back
def.Renderer.ColorModulation = modulation;
//Commit changes back to the CIM
pcsl.SetDefinition(def);

Edit The Renderer to use Fixed Size

//Must be called on the MCT
//var pcsl = ...;
var def = pcsl.GetDefinition() as CIMPointCloudLayer;

//Set the point shape and sizing on the renderer
def.Renderer.PointShape = PointCloudShapeType.DiskShaded;
var pointSize = new CIMPointCloudFixedSizeAlgorithm()
{
  UseRealWorldSymbolSizes = false,
  Size = 8
};
def.Renderer.PointSizeAlgorithm = pointSize;
//Commit changes back to the CIM
pcsl.SetDefinition(def);

Edit the Renderer to Scale Size

//Must be called on the MCT
//var pcsl = ...;
var def = pcsl.GetDefinition() as CIMPointCloudLayer;

//Set the point shape and sizing on the renderer
def.Renderer.PointShape = PointCloudShapeType.DiskFlat;//default
var scaleSize = new CIMPointCloudSplatAlgorithm()
{
  MinSize = 8,
  ScaleFactor = 1.0 //100%
};
def.Renderer.PointSizeAlgorithm = scaleSize;
//Commit changes back to the CIM
pcsl.SetDefinition(def);

Edit Density settings

//Must be called on the MCT
//var pcsl = ...;
var def = pcsl.GetDefinition() as CIMPointCloudLayer;
//PointsBudget - corresponds to Display Limit on the UI
// - the absolute maximum # of points to display
def.PointsBudget = 1000000;

//PointsPerInch - corresponds to Density Min --- Max on the UI
// - the max number of points per display inch to renderer
def.PointsPerInch = 15;
//Commit changes back to the CIM
pcsl.SetDefinition(def);
