Rendering node that displays a clip line of a surface mesh.
A clip line is an unstructured line mesh defined by the intersection of several arbitrary planes with a surface mesh. Two types of clip line are possible:
a clip line is the projection along a direction of an input polyline onto a 3D surface mesh. This type of clip line requires at least 2 points in the polyline. The projected polyline follows the shape of the 3D surface.
The ClipLine example highlights this first use case.
a clip line is the intersection of a plane and a 3D surface when the field polyline contains one single point. The plane is defined by the point of the polyline and its normal vector defined by direction. If the 3D surface is flat, the output clip line follows a straight line. If the 3D surface corresponds to the external skin of a volume, the clip line is a closed contour.
The ClipLineOnSkin example highlights this second use case.
The line 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 MoScalarSet node). To disable coloring set this field to -1. Rendering can be modified using various property nodes (see the SEE ALSO section).
