Detailed Description

MeshViz Rendering node that displays isolines on a surface mesh.

Isolines are a collection of unstructured line meshes defined by the points having the specified values in the scalar data set. You can specify a list of iso values, the period of major contour lines and line patterns for the major and minor contour lines.

The scalar set used to extract the isolines is defined by the isoScalarSetId field. This is an index into the list of scalar sets existing in the traversal state (see the MoScalarSetxxx nodes). This scalar set must be defined per node to be valid.

The isolines can be colored using a scalar set defined in the colorScalarSetId inherited field. To disable coloring set this field to -1.

FILE FORMAT/DEFAULT

    MeshIsoline {
    colorScalarSetId 0
    parallel TRUE
    isovalues 0.0
    isoScalarSetId 0
    majorPeriod 3
    firstMajor 0
    majorLinePattern 0xFFFF
    minorLinePattern 0xFFFF
    }
