Remarks

Class to build a vectors field on a surface mesh. This class handles all vectors attributes. A vector is represented by an arrow made of 3 parts, the body, the start-shape and the end-shape. The body is a line or a cylinder starting from a node of the mesh. The start-shape is a pattern drawn at the node position. The end-shape is a pattern drawn at the other extremity of the body. Several type of pattern can be used to draw the shape. The 3 parts can be scaled and colored according to the value of the different fields of the class.

The current mesh is used for the representation of vectors. See OIV.MeshViz.Data.PoMesh for more explanations about the current mesh. The vectors of the mesh to be drawn, are defined by the method addVecsSet of the current mesh (see OIV.MeshViz.Nodes.PoMeshProperty, OIV.MeshViz.Data.PbMesh or OIV.MeshViz.Data.PbMesh2D), and by the field OIV.MeshViz.Data.PoMesh.vecsIndex. The node of the mesh are used as start point of the representation of the vectors.
