Detailed Description

ConnectivityTracer is volumetric ray tracer for unstructured grids.

Capabilities include volume rendering and integrating absorption and emission of N energy groups for simulated radiograhy.

Member Function Documentation

◆ AccumulatePathLengths()

template<typename FloatType >

void vtkm::rendering::raytracing::ConnectivityTracer::AccumulatePathLengths	(	Ray< FloatType > &	rays,
		detail::RayTracking< FloatType > &	tracker
	)

private

◆ FindLostRays()

template<typename FloatType >

void vtkm::rendering::raytracing::ConnectivityTracer::FindLostRays	(	Ray< FloatType > &	rays,
		detail::RayTracking< FloatType > &	tracker
	)

private

◆ FindMeshEntry()

template<typename FloatType >

void vtkm::rendering::raytracing::ConnectivityTracer::FindMeshEntry ( Ray< FloatType > & rays )

Find the entry point in the mesh.

◆ FullTrace()

template<typename FloatType >

void vtkm::rendering::raytracing::ConnectivityTracer::FullTrace ( Ray< FloatType > & rays )

Traces rays fully through the mesh.

Rays can exit and re-enter multiple times before leaving the domain. This is fast path for structured meshs or meshes that are not interlocking. Note: rays will be compacted

◆ GetMeshContainer()

MeshConnectivityContainer* vtkm::rendering::raytracing::ConnectivityTracer::GetMeshContainer ( )

inline

◆ GetNumberOfMeshCells()

vtkm::Id vtkm::rendering::raytracing::ConnectivityTracer::GetNumberOfMeshCells ( ) const

◆ Init()

void vtkm::rendering::raytracing::ConnectivityTracer::Init ( )

◆ IntegrateCells()

template<typename FloatType >

void vtkm::rendering::raytracing::ConnectivityTracer::IntegrateCells	(	Ray< FloatType > &	rays,
		detail::RayTracking< FloatType > &	tracker
	)

private

◆ IntegrateMeshSegment()

template<typename FloatType >

void vtkm::rendering::raytracing::ConnectivityTracer::IntegrateMeshSegment ( Ray< FloatType > & rays )

Integrates the active rays though the mesh until all rays have exited.

Precondition: rays.HitIdx is set to a valid mesh cell

◆ IntersectCell()

template<typename FloatType >

void vtkm::rendering::raytracing::ConnectivityTracer::IntersectCell	(	Ray< FloatType > &	rays,
		detail::RayTracking< FloatType > &	tracker
	)

private

◆ LogTimers()

void vtkm::rendering::raytracing::ConnectivityTracer::LogTimers ( )

◆ OffsetMinDistances()

template<typename FloatType >

void vtkm::rendering::raytracing::ConnectivityTracer::OffsetMinDistances ( Ray< FloatType > & rays )

private

◆ PartialTrace()

template<typename FloatType >

std::vector<PartialComposite<FloatType> > vtkm::rendering::raytracing::ConnectivityTracer::PartialTrace ( Ray< FloatType > & rays )

Integrates rays through the mesh.

If rays leave the mesh and re-enter, then those become two separate partial composites. This is need to support domain decompositions that are like puzzle pieces. Note: rays will be compacted

◆ PrintRayStatus()

template<typename FloatType >

void vtkm::rendering::raytracing::ConnectivityTracer::PrintRayStatus ( Ray< FloatType > & rays )

private

◆ ResetTimers()

void vtkm::rendering::raytracing::ConnectivityTracer::SetSampleDistance ( const vtkm::Float32 & distance )
