Member Function Documentation

◆ _checkBoundingBox()

void Arcane::BasicRayMeshIntersection::_checkBoundingBox	(	Real3	p,
		Real3 *ARCANE_RESTRICT	min_bounding_box,
		Real3 *ARCANE_RESTRICT	max_bounding_box )

inline

Definition at line 474 of file BasicRayMeshIntersection.cc.

◆ build()

virtual void Arcane::BasicRayMeshIntersection::build ( void )

inlinevirtual

Build-level construction of the service.

This method is called right after the constructor.

Reimplemented from Arcane::AbstractService.

Definition at line 445 of file BasicRayMeshIntersection.cc.

◆ compute() [1/2]

void Arcane::BasicRayMeshIntersection::compute	(	IItemFamily *	ray_family,
		VariableParticleReal3 &	rays_position,
		VariableParticleReal3 &	rays_direction,
		VariableParticleInt32 &	rays_orig_face,
		VariableParticleInt32 &	user_values,
		VariableParticleReal3 &	intersections,
		VariableParticleReal &	distances,
		VariableParticleInt32 &	rays_face )

virtual

Calculates the intersection of rays.

Calculates the intersection of rays in the family ray_family with the surface of the mesh. The position and direction of the rays are given by the variables rays_position and rays_direction. The array rays_orig_face contains the local ID of the face from which the ray originates. This array is used in the IRayFaceIntersector.

In return, rays_face will contain for each ray the localId() of the intersected face or NULL_ITEM_LOCAL_ID if a ray does not intersect any face. The array rays_intersection returns the position of the intersection point and rays_distance the distance of the intersection point relative to the ray origin. The array user_values is filled in return by the IRayFaceIntersector.

In parallel, the rays in the family are exchanged between sub-domains so that a ray is in the same sub-domain as the owner of the intersected face. If a ray does not intersect any face, it remains in this sub-domain.

Implements Arcane::IRayMeshIntersection.

◆ compute() [2/2]

void Arcane::BasicRayMeshIntersection::compute	(	Real3ConstArrayView	segments_position,
		Real3ConstArrayView	segments_direction,
		Int32ConstArrayView	orig_faces_local_id,
		Int32ArrayView	user_values,
		Real3ArrayView	intersections,
		RealArrayView	distances,
		Int32ArrayView	faces_local_id )

virtual

Calculates the intersection.

In return, the array faces_local_id contains the local ID of the intersected face for each segment. If a segment does not intersect any face, the corresponding local_id is NULL_ITEM_LOCAL_ID.

Implements Arcane::IRayMeshIntersection.

Here is the caller graph for this function:

◆ faceIntersector()

virtual IRayFaceIntersector * Arcane::BasicRayMeshIntersection::faceIntersector ( )

inlinevirtual

Intersector used (0 if none specified).

Implements Arcane::IRayMeshIntersection.

Definition at line 467 of file BasicRayMeshIntersection.cc.

◆ setFaceIntersector()

virtual void Arcane::BasicRayMeshIntersection::setFaceIntersector ( IRayFaceIntersector * intersector )

inlinevirtual

Sets the intersection callback.

This allows the caller to specify its method for calculating the intersection of a ray with a face. If this method is not called, a default intersector is used.

Implements Arcane::IRayMeshIntersection.
