Syntax

public class VisibilityTester

Constructors

VisibilityTester(IPointCloudOctree, TriggerPointLoading)

Creates a new instance.

Declaration

public VisibilityTester(IPointCloudOctree octree, TriggerPointLoading tryAddPointsToCacheHandler)

Parameters

Type	Name	Description
IPointCloudOctree	octree	The octree the visibility algorithm is working on.
TriggerPointLoading	tryAddPointsToCacheHandler	Inject a method that loads the points and adds the loaded points in to cache, if needed.

Properties

CamPos

Current camera position - set by the SceneRenderer if a PointCloud Component is visited.

Declaration

public float3 CamPos { get; set; }

Property Value

Type	Description
float3

Fov

Current Field of View - set by the SceneRenderer if a PointCloud Component is visited.

Declaration

public float Fov { get; set; }

Property Value

Type	Description
System.Single

MinProjSizeModifier

Declaration

public float MinProjSizeModifier { get; set; }

Property Value

Type	Description
System.Single

Model

Model matrix of the SceneNode the point cloud (component) is part of.

Declaration

public float4x4 Model { get; set; }

Property Value

Type	Description
float4x4

NumberOfVisiblePoints

The number of points that are currently visible.

Declaration

public int NumberOfVisiblePoints { get; }

Property Value

Type	Description
System.Int32

Octree

The octree structure of the point cloud.

Declaration

public IPointCloudOctree Octree { get; set; }

Property Value

Type	Description
IPointCloudOctree

PointThreshold

Maximal number of points that are visible in one frame - trade off between performance and quality.

Declaration

public int PointThreshold { get; set; }

Property Value

Type	Description
System.Int32

RenderFrustum

Current camera frustum - set by the SceneRenderer if a PointCloud Component is visited.

Declaration

public FrustumF RenderFrustum { get; set; }

Property Value

Type	Description
FrustumF

UpdateRate

The amount of milliseconds needed to pass before rendering next frame

Declaration

public float UpdateRate { get; set; }

Property Value

Type	Description
System.Single

ViewportHeight

Current height of the viewport - set by the SceneRenderer if a PointCloud Component is visited.

Declaration

public int ViewportHeight { get; set; }

Property Value

Type	Description
System.Int32

VisibleNodes

All nodes that are visible in this frame.

Declaration

public List<OctantId> VisibleNodes { get; }

Property Value

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

Methods

Update()

Updates the visible octree hierarchy in the scene and updates the VisibleOctreeHierarchyTex in the shaders.

Declaration

public void Update()
