Parameter

Type

Description

Count

2D Array

Number of control vertex, uknots, vknots per surface

ControlPoints

1D or 3D Array

The control points used for creating the nurbs surface. The control points can be stored in a 1-dimensional array or in a 3-dimensional matrix (UxVx4) of x,y,z,w values. The 1-dimensional array should contain the number of points in U and V at the beginning followed by a sequence of x,y,z,w values (e.g. {U,V,Xo,Yo,Zo,...X(uv-1),Y(uv-1),Z(uv-1),W(uv-1)}).

UKnots

Array

A vector of knot values in the U direction.

Default Value: Knots derived from control points.

VKnots

Array

A vector of knot values in the V direction.

Default Value: Knots derived from control points.

UClosed

Array of Booleans

Specifies whether the nurbs surface is closed or not in U direction.

Default Value: False

VClosed

Array of Booleans

Specifies whether the nurbs surface is closed or not in V direction.

Default Value: False

UDegree

Array of Longs

Degree of the nurbs surface in U direction.

Default Value: 3

VDegree

Array of Longs

Degree of the nurbs surface in V direction.

Default Value: 3

UParam

Array of siKnotParameterization

The parameterization factor of the nurbs surface in U direction.

Default Value: siNonUniformParameterization

VParam

Array of siKnotParameterization

The parameterization factor of the nurbs surface in V direction.

Default Value: siNonUniformParameterization

NurbsFormat

siNurbsFormat

Specifies how the data is formatted.

Default Value: siSINurbs

Name

String

Name of object
