◆ Grid()

const chi_mesh::MeshContinuum & chi_mesh::RayTracer::Grid ( ) const
private

Definition at line 7 of file raytracer.cc.

◆ SetTolerancesFromCellSize()

void chi_mesh::RayTracer::SetTolerancesFromCellSize ( double  cell_size)
inlineprivate

Definition at line 44 of file raytracing.h.

◆ TraceIncidentRay()

chi_mesh::RayTracerOutputInformation chi_mesh::RayTracer::TraceIncidentRay ( const Cell &  cell,
const Vector3 &  pos_i,
const Vector3 &  omega_i 
)

Traces a ray with an initial position, presumed to be outside the cell, to an incident face.

Definition at line 134 of file raytracer.cc.

◆ TracePolygon()

void chi_mesh::RayTracer::TracePolygon ( const Cell &  cell,
Vector3 &  pos_i,
Vector3 &  omega_i,
bool &  intersection_found,
bool &  backward_tolerance_hit,
RayTracerOutputInformation &  oi 
)
private

Performs raytracing within a 2D Polygon.

◆ TracePolyhedron()

void chi_mesh::RayTracer::TracePolyhedron ( const Cell &  cell,
Vector3 &  pos_i,
Vector3 &  omega_i,
bool &  intersection_found,
bool &  backward_tolerance_hit,
RayTracerOutputInformation &  oi 
)
private

Performs raytracing within a 3D Polyhedron.

Definition at line 8 of file raytracer_3D_polyhedron.cc.

◆ TraceRay()

chi_mesh::RayTracerOutputInformation chi_mesh::RayTracer::TraceRay ( const Cell &  cell,
Vector3 &  pos_i,
Vector3 &  omega_i,
int  function_depth = 0 
)

Traces a ray with an initial position either within the cell or on the cell surface, and with a direction vector pointing inward toward the cell. If the ray-trace fails the particle will be marked as lost.

Definition at line 13 of file raytracer.cc.

bool &  backward_tolerance_hit,
RayTracerOutputInformation &  oi 
)
private

Performs raytracing within a 1D-slab.
