This class describes a polyhedron mesh made of faces and vertices.

The faces do not have to be triangle.

Member Function Documentation

◆ addFace()

RP3D_FORCE_INLINE void reactphysics3d::HalfEdgeStructure::addFace ( const Array< uint32 > & faceVertices )

Add a face.

Parameters

faceVertices Array of the vertices in a face (ordered in CCW order as seen from outside the polyhedron). The indices are the internal indices of the vertices inside the HalfEdgeStructure.

◆ addVertex()

RP3D_FORCE_INLINE uint32 reactphysics3d::HalfEdgeStructure::addVertex ( uint32 vertexPointIndex )

Add a vertex.

Parameters

vertexPointIndex Index of the vertex in the external user vertex data array

◆ getFace()

RP3D_FORCE_INLINE const HalfEdgeStructure::Face & reactphysics3d::HalfEdgeStructure::getFace ( uint32 index ) const

Return a given face.

Returns: A given face of the polyhedron

◆ getHalfEdge()

RP3D_FORCE_INLINE const HalfEdgeStructure::Edge & reactphysics3d::HalfEdgeStructure::getHalfEdge ( uint32 index ) const

Return a given edge.

Returns: A given edge of the polyhedron

◆ getNbFaces()

RP3D_FORCE_INLINE uint32 reactphysics3d::HalfEdgeStructure::getNbFaces ( ) const

Return the number of faces.

Returns: The number of faces in the polyhedron

◆ getNbHalfEdges()

RP3D_FORCE_INLINE uint32 reactphysics3d::HalfEdgeStructure::getNbHalfEdges ( ) const

Return the number of half-edges.

Returns: The number of edges in the polyhedron

◆ getNbVertices()

RP3D_FORCE_INLINE uint32 reactphysics3d::HalfEdgeStructure::getNbVertices ( ) const

Return the number of vertices.
