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
Public NotInheritable Class PointCloudSceneLayer Inherits Layer Implements ArcGIS.Desktop.Core.IMetadataInfo, IMetadataSource, System.ComponentModel.INotifyPropertyChanged
public sealed class PointCloudSceneLayer : Layer, 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 scenelayerName = pointCloudSceneLayer?.Name;
}
Edit Color Modulation
{
// Note: call within QueuedTask.Run()
{
var def = pointCloudSceneLayer.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
pointCloudSceneLayer.SetDefinition(def);
}
}
Edit The Renderer to use Fixed Size
{
// Note: call within QueuedTask.Run()
{
var def = pointCloudSceneLayer.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
pointCloudSceneLayer.SetDefinition(def);
}
}
Edit the Renderer to Scale Size
{
// Note: call within QueuedTask.Run()
{
var def = pointCloudSceneLayer.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
pointCloudSceneLayer.SetDefinition(def);
}
}
Edit Density settings
{
// Note: call within QueuedTask.Run()
{
var def = pointCloudSceneLayer.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
pointCloudSceneLayer.SetDefinition(def);
}
