Member Function Documentation

build()

virtual void Arcane::IRayMeshIntersection::build ( )

pure virtual

Builds the instance.

Implemented in Arcane::BasicRayMeshIntersection.

compute() [1/2]

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

pure 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.

Implemented in Arcane::BasicRayMeshIntersection.

compute() [2/2]

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

pure 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.

Implemented in Arcane::BasicRayMeshIntersection.

faceIntersector()

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

pure virtual

Intersector used (0 if none specified).

Implemented in Arcane::BasicRayMeshIntersection.

setFaceIntersector()

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

pure virtual

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.

Implemented in Arcane::BasicRayMeshIntersection.
