Remarks

A mesh is a set of nodes linked by edges. A mesh can be a surface mesh (see OIV.MeshViz.Data.PbMesh2D) or a volume mesh (see OIV.MeshViz.Data.PbMesh3D). A surface mesh can be either 2D (its nodes have 2 coordinates) or 3D (its nodes have 3 coordinates). Each node is referred to by an index named node_index.

A mesh is composed of a list of cells. A cell is a "simple" basic volume or surface element that connects adjacent nodes of the mesh. Surface meshes can be defined by triangles, quadrangles and polygonal cells. Volume meshes can be defined by tetrahedrons, hexahedrons, prisms, or pyramid cells. A cell is defined by the list of nodes (node indices) that it connects. The order of the nodes that define a cell is the same for each cell in the mesh. Each cell is referred to by an index named cell_index.

A list of value-set can be defined. A value is a scalar (float), string, or a vector. Each value is located on mesh node, so the number of values in a set must be equal to the number of mesh's nodes. Each set of values can be named by a string.

A scalar value set is used to color the representations of the mesh. A string value set is used by some charting representations. A vector value set is used to make "hedgehog" vector field representations, or streamline representations. Each data-set is referred by an index named set_index. This index is used by classes of mesh representation to indicate which value set must be used for coloring. (see OIV.MeshViz.Data.PoMesh.valuesIndex and OIV.MeshViz.Data.PoMesh.vecsIndex). Mapping a scalar value onto a color is done by OIV.MeshViz.Graph.PbDataMapping or OIV.MeshViz.Nodes.PoDataMapping classes (and derived).

Data duplication:

If the last argument is_data_duplicate of a constructor of a derived class is false, the geometry and values sets are not copied by the object. In this case, the methods setGeometry, addValuesSet, addStringsSet and addVecsSet save only the adress of the user data set and it is the application's responsibility to manage the validity of data during the existence of the mesh object.
