Detailed Description

template<class T = size_t>
class rw::geometry::IndexedTriArray< T >

this class is a proxy to a triangle mesh where the triangles can be indirectly copied in an efficient manner.

Each "virtual" triangle index is mapped to the actual triangle index. By rearanging the mapping the order of the triangles in the mesh are rearanged to the proxy user, without changing the actual triangle mesh.

Constructor & Destructor Documentation

◆ IndexedTriArray() [1/3]

IndexedTriArray ( TriMesh::Ptr  objArr)
inline

constructor - creates a proxy that initially maps triangles from [0:0,1:1,2:2,....,i:i]

Parameters
objArr[in] the triangle mesh on which to create a proxy

◆ IndexedTriArray() [2/3]

IndexedTriArray ( TriMesh::Ptr  objArr,
rw::core::Ptr< std::vector< T >>  idxArr 
)
inline

constructor - creates a proxy where the initial mapping is determined by idxArr.

idxArr must be same length as the number of triangles.

Parameters
objArr[in] the triangle mesh on which to create a proxy
idxArr[in] the index mapping

◆ IndexedTriArray() [3/3]

IndexedTriArray ( TriMesh::Ptr  objArr,
rw::core::Ptr< std::vector< T >>  idxArr,
rw::core::Ptr< std::vector< rw::math::Vector3D< float >>>  centerArr,
rw::core::Ptr< std::vector< float >>  valArr,
rw::core::Ptr< std::vector< boost::tuple< T, float, rw::math::Vector3D< float >>>>  valCenterArr,
size_t  first,
size_t  last 
)
inline

constructor - creates a proxy that only references part of the triangle mesh. the part is specified in the range from first to last

Parameters
objArr[in] the triangle mesh on which to create a proxy
idxArr[in] the index mapping
first[in] the first index
centerArr
valArr
valCenterArr
last
