Syntax

public abstract class PointCloudDataHandlerBase<TGpuData>

Type Parameters

Name	Description
TGpuData

Fields

DisposeQueue

Contains meshes that are marked for disposal.

Declaration

protected Dictionary<OctantId, IEnumerable<TGpuData>> DisposeQueue

Field Value

Type	Description
System.Collections.Generic.Dictionary<OctantId, System.Collections.Generic.IEnumerable<TGpuData>>

DisposeRate

Used to manage gpu pressure when disposing of a large quantity of meshes.

Declaration

public float DisposeRate

Field Value

Type	Description
System.Single

LoadingQueue

Contains nodes that are queued for loading in the background.

Declaration

protected List<OctantId> LoadingQueue

Field Value

Type	Description
System.Collections.Generic.List<OctantId>

LockDisposeQueue

Locking object for the dispose queue.

Declaration

protected static object LockDisposeQueue

Field Value

Type	Description
System.Object

LockLoadingQueue

Locking object for the loading queue.

Declaration

protected static object LockLoadingQueue

Field Value

Type	Description
System.Object

MaxNumberOfNodesToLoad

Number of nodes that will be loaded, starting with the one with the biggest screen projected size to ensure no octant is loaded that will be invisible in a few frames. Load the five biggest nodes (screen projected size) as proposed in Schütz' thesis.

Declaration

protected int MaxNumberOfNodesToLoad

Field Value

Type	Description
System.Int32

Methods

GetGpuData(OctantId)

First looks in the mesh cache, if there are meshes return, else look in the DisposeQueue, if there are meshes return, else look in the point cache, if there are points create a mesh and add to the MeshCache.

Declaration

public abstract IEnumerable<TGpuData> GetGpuData(OctantId guid)

Parameters

Type	Name	Description
OctantId	guid	The unique id of an octant.

Returns

Type	Description
System.Collections.Generic.IEnumerable<TGpuData>

ProcessDisposeQueue()

Disposes of unused meshes, if needed. Depends on the dispose rate and the expiration frequency of the MeshCache.

Declaration

public abstract void ProcessDisposeQueue()

TriggerPointLoading(OctantId)

Loads points from the hard drive if they are neither in the loading queue nor in the PointCahce.

Declaration

public abstract void TriggerPointLoading(OctantId guid)

Parameters

Type	Name	Description
OctantId	guid	The octant for which the points should be loaded.
