getBoundingBox()

GeoLib::AABB MeshToolsLib::MeshInformation::getBoundingBox ( const MeshLib::Mesh & mesh )

static

Returns the bounding box of the mesh.

getMaterialIDs()

std::vector< int > MeshToolsLib::MeshInformation::getMaterialIDs ( const MeshLib::Mesh & mesh )

static

writes out a list of all material IDs that occur in the mesh.

Definition at line 167 of file MeshInformation.cpp.

getNumberOfElementTypes()

std::map< MeshLib::MeshElemType, unsigned > MeshToolsLib::MeshInformation::getNumberOfElementTypes ( const MeshLib::Mesh & mesh )

static

Returns an array with the number of elements of each type in the given mesh. On completion, n_element_types array contains the number of elements of each of the seven supported types. The index to element type conversion is this: 0: #lines 1: #triangles 2: #quads 3: #tetrahedra 4: #hexahedra 5: #pyramids 6: #prisms
