Detailed Description

The MeshTrackerComponent class manages requests for environmental mesh data, processes the results and provides them to the calling system. The calling system is able request environmental mesh data within a specified area. Various other search criteria can be set via this class's public properties. Mesh data requests are processed on a separate thread. Once a mesh data request has been processed the calling system will be notified via an FOnMeshTrackerUpdated broadcast.

Constructor & Destructor Documentation

~UMockDataMeshTrackerComponent()

UMockDataMeshTrackerComponent::~UMockDataMeshTrackerComponent

(

)

Destroys the FMeshTrackerImpl instance.

Member Function Documentation

BeginDestroy()

void UMockDataMeshTrackerComponent::BeginDestroy ( )

overridevirtual

Unlinks the current procedural mesh component from the mesh tracking system.

ConnectMRMesh()

void UMockDataMeshTrackerComponent::ConnectMRMesh

(

class UMRMeshComponent *

InMRMeshPtr

)

Sets the procedural mesh component that will store and display the environmental mesh results.

Parameters

InMRMeshPtr

The procedural mesh component to store the query result in.

DECLARE_DYNAMIC_MULTICAST_DELEGATE_FiveParams()

UMockDataMeshTrackerComponent::DECLARE_DYNAMIC_MULTICAST_DELEGATE_FiveParams	(	FOnMockDataMeshTrackerUpdated	,
		int32	,
		Index	,
		const TArray< FVector > &	,
		Vertices	,
		const TArray< int32 > &	,
		Triangles	,
		const TArray< FVector > &	,
		Normals	,
		const TArray< float > &	,
		Confidence
	)

Delegate used by OnMeshUpdated().

Parameters

Index	The index of the mesh section in the ProceduralMeshComponent that was updated.
Vertices	List of all vertices in the updated mesh section.
Triangles	List of all triangles in the updated mesh section.
Normals	List of the normals of all triangles in the updated mesh section.
Confidence	List of the confidence values per vertex in the updated mesh section. This can be used to determine if the user needs to scan more.

DisconnectMRMesh()

void UMockDataMeshTrackerComponent::DisconnectMRMesh

(

class UMRMeshComponent *

InMRMeshPtr

)

Unlinks the current procedural mesh component from the mesh tracking system.

Parameters

InMRMeshPtr

The procedural mesh component to unlink from the mesh tracking system.

FinishDestroy()

void UMockDataMeshTrackerComponent::FinishDestroy ( )

overridevirtual

Destroys the interface object to the mesh tracking api

TickComponent()

void UMockDataMeshTrackerComponent::TickComponent ( float  DeltaTime, enum ELevelTick  TickType, FActorComponentTickFunction *  ThisTickFunction  )

overridevirtual

The procedural mesh generated should bake physics and update its collision data. TODO: Can we calculate this based on the collision flags of the UProceduralMeshComponent? It seems like those are not being respected directly by the component. Polls for and handles the results of the environmental mesh queries.

Member Data Documentation

BlockVertexColors

TArray<FColor> UMockDataMeshTrackerComponent::BlockVertexColors

Colors through which we cycle when setting vertex color by block.

MRMesh

TObjectPtr<class UMRMeshComponent> UMockDataMeshTrackerComponent::MRMesh

MRMeshComponent can render and provide collision based on the Mesh data.

OnMeshTrackerUpdated

FOnMockDataMeshTrackerUpdated UMockDataMeshTrackerComponent::OnMeshTrackerUpdated

Activated whenever new information about this mesh tracker is detected.

RequestNormals

bool UMockDataMeshTrackerComponent::RequestNormals = true

If true, the system will generate normals for the triangle vertices.

RequestVertexConfidence

bool UMockDataMeshTrackerComponent::RequestVertexConfidence = false

If true, the system will generate the mesh confidence values for the triangle vertices. These confidence values can be used to determine if the user needs to scan more.

ScanWorld

bool UMockDataMeshTrackerComponent::ScanWorld = true

Set to true to start scanning the world for meshes.

UpdateInterval

float UMockDataMeshTrackerComponent::UpdateInterval = 3.0f

Update Interval in Seconds.

VertexColorFromConfidenceOne

FLinearColor UMockDataMeshTrackerComponent::VertexColorFromConfidenceOne

Color mapped to confidence value of one.

VertexColorFromConfidenceZero

FLinearColor UMockDataMeshTrackerComponent::VertexColorFromConfidenceZero

Color mapped to confidence value of zero.

VertexColorMode

EMeshTrackerVertexColorMode UMockDataMeshTrackerComponent::VertexColorMode = EMeshTrackerVertexColorMode::None

Vertex Colors can be unused, or filled with several types of information.
