(Inherited from SoFieldContainer.) |
This node defines an additional set of properties used by OIV.Inventor.Nodes.SoNurbsSurface when rendering NURBS surfaces.
For a large NURBS surface, it is sometimes more effective to display two central isoparametric curves rather than facet boundaries (as in wireframe mode) because the latter may provide an overly complicated view of the surface.
This node allows you to specify the NURBS draw style; the color of the trim curves, boundaries and isoparametric curves; the line pattern of the isoparametric curves; the number of sample points between trim curves control points; the type of tessellation; angle and distance for adaptive tessellation.
The NURBS draw style is a bitmask specifying which combination of the following representations to use for displaying the NURBS: normal display, trim curves and boundaries, and/or central isoparametric curves.
Turning off the normal NURBS surface display, and turning on the display of trim curves, boundaries and isoparametric curves can dramatically speed up rendering of large models.
When in ADAPTIVE tessellation mode, regions with a low curvature will be less tessellated than regions with a high curvature.
