template<typename _MdExtractorT > | |
class | MdMeshMultiLinesRepresentation |
Rendering node that displays streamlines of a vector field on a volume mesh.
Displays a list of MiLineMeshCurvilinear meshes containing streamlines starting from a list of source points and probes the input mesh to compute the values at the streamline nodes (See the SEE ALSO Section for settings).
A streamline is a line that is everywhere tangent to a vector field. The vector field is specified by the vec3SetId field. This is an index into the list of vector sets existing in the traversal state (see the MoVec3Setxxx nodes).
Note: Streamlines are meaningless for unsteady flow, because time is not taken into account during the computation of the lines. Streamlines are integrated from a given set of vectors using a Runge/Kutta method of order 2 .
The lines can be colored using a scalar set defined in the colorScalarSetId inherited field. This is an index into the list of scalar sets existing in the traversal state (see the MoScalarSetxxx nodes). To disable coloring set this field to -1.
