Topics in this section describe how you can control the way 3ds Max generates NURBS curves and surfaces.
Topics in this section
NURBS Curve Approximation
Although NURBS curves are analytically generated, in order to generate and display them they must be approximated by line segments.
NURBS Surface Approximation
Although NURBS surfaces are analytically generated, in order to generate and display them they must be approximated by faces. You use the controls described in this section to set the type of approximation used and its parameters.
Advanced Surface Approximation Dialog (NURBS)
This dialog sets parameters that control the tessellation used in the Spatial, Curvature, and Spatial and Curvature approximation methods.
Surface Approximation Utility (NURBS)
The Surface Approximation utility lets you change approximation and display settings without going into the NURBS model, and is especially useful for changing settings on multiple NURBS objects at once.
