Display > NURBS

 
 
 
CVs

Show control vertices (CV)'s for the selected NURBS surfaces.

Edit Points

Display edit points for the selected NURBS surfaces.

Hulls

Display hulls for the selected NURBS surfaces.

Normals (Shaded Mode)

Show normals for the selected NURBS surfaces. Normals only appear in Shaded Mode (Hotkey: 5).

Patch Centers

Display small squares at patch centers.

Surface Origins

Show the origin curve of the NURBS surfaces.

Custom

Allows you to customize your NURBS display options by setting many options at once. You can specify the scope of which NURBS objects display their components using the Scope drop-down list. The scope can be active objects, all objects, new curves, or new surfaces.

Hull

Shows hulls only. You can apply the setting to active objects or to all objects. Additionally, the options allow you to control the number of hull divisions displayed.

Rough/Medium/Fine

Displays objects at preset levels of quality. Selecting Medium or Fine slows the display and interactive performance, but improves image precision.

The options for these selections allows you to apply the setting to active objects or to all objects.

Note

The hotkeys for these settings are: 1 (Rough), 2 (Medium) and 3 (Fine).

Custom Smoothness

Lets you customize the display quality.

In the following figure, an object’s smoothness is changed from a default medium level of quality to a custom hull quality level.

NURBS Smoothness (Custom) options

Objects Affected

Select from Active objects or All objects.

Geometry

To display all geometry, select Full. To display hulls only, select Hull.

Wireframe

Surface Div per Span USurface Div per Span V

Together, these settings subdivide the NURBS patches for display purposes to give it the appearance of a finer mesh. The range is from 0 to 32.

Curve Div per Span

Specifies the number of curve divisions per span to give the curves a rougher or smoother appearance. The range is from 1 to 128.

Shaded

Display Render Tessellation Geometry

Turn on to see the pattern of tessellation that the renderer will use for the surface. You must be in shade mode to see this pattern.

Surface Div per Span

Specifies the number of surface divisions per span in shaded mode. The range is from 0 to 32.

Hull

Hull Simplification UHull Simplification V

If you have the Geometry set to Hull, you can use these settings to control the number of hull divisions displayed.
