Detailed Description

The NurbsTextureCoordinate node is a NURBS surface existing in the parametric domain of its surface host specifying the mapping of the texture onto the surface.

The parameters are as specified in NurbsTextureCoordinate with the exception that the control points are specified in (u, v) coordinates.

The tessellation process generates 2D texture coordinates. If a NurbsTextureCoordinate is undefined, texture coordinates are computed by the client on the basis of parametric step size. Conventional vertex parameters do not apply on NURBS surfaces because triangles are only available after polygonalization. However, the conventional texture transform may be used.

NurbsTextureCoordinate nodes are accessed through the texCoord field of a node derived from NurbsTextureCoordinate. A NurbsTextureCoordinate node separately encountered is ignored.

Member Function Documentation

◆ defaultXMLContainerField()

virtual string H3D::NurbsTextureCoordinate::defaultXMLContainerField ( )
inlinevirtual

Returns the default xml containerField attribute value.

For this node it is "texCoord".

Reimplemented from H3D::Node.

Member Data Documentation

◆ controlPoint

H3DUniquePtr< MFVec2f > H3D::NurbsTextureCoordinate::controlPoint

controlPoint defines a set of control points of dimension uDimension x vDimension.

This set of points defines a mesh where the points do not have a uniform spacing. uDimension points define a polyline in u-direction followed by further u-polylines with the v-parameter in ascending order. The number of control points shall be equal or greater than the order. The control points are specified as (u, v) coordinates in this node.

Access type: inputOutput

Referenced by NurbsTextureCoordinate(), and renderTexForNurbs().

◆ uDimension

H3DUniquePtr< SFInt32 > H3D::NurbsTextureCoordinate::uDimension

Defines the number of control points in the u dimension.

Access type: inputOutput
Default value: 0

Referenced by NurbsTextureCoordinate(), and renderTexForNurbs().

◆ uKnot

H3DUniquePtr< MFDouble > H3D::NurbsTextureCoordinate::uKnot

Defines the knot values of the surface in the u dimension.

Access type: inputOutput

Referenced by NurbsTextureCoordinate(), and renderTexForNurbs().

◆ uOrder

H3DUniquePtr< SFInt32 > H3D::NurbsTextureCoordinate::uOrder

Defines the order of the surface in the u dimension.

Access type: inputOutput
Default value: 3

Referenced by NurbsTextureCoordinate(), and renderTexForNurbs().

◆ vDimension

H3DUniquePtr< SFInt32 > H3D::NurbsTextureCoordinate::vDimension

Defines the number of control points in the v dimension.

Access type: inputOutput
Default value: 0

Referenced by NurbsTextureCoordinate(), and renderTexForNurbs().

◆ vKnot

H3DUniquePtr< MFDouble > H3D::NurbsTextureCoordinate::vKnot

Defines the knot values of the surface in the v dimension.

Access type: inputOutput

Referenced by NurbsTextureCoordinate(), and renderTexForNurbs().

◆ vOrder

H3DUniquePtr< SFInt32 > H3D::NurbsTextureCoordinate::vOrder

Defines the order of the surface in the v dimension.

Access type: inputOutput
Default value: 3

Referenced by NurbsTextureCoordinate(), and renderTexForNurbs().

◆ weight

H3DUniquePtr< MFFloat > H3D::NurbsTextureCoordinate::weight

A weight value that shall be greater than zero is assigned to each controlPoint.

The ordering of the values is equivalent to the ordering of the control point values. The number of values shall be identical to the number of control points. If the length of the weight vector is 0, the default weight 1.0 is assumed for each control point, thus defining a non-Rational curve. If the number of weight values is less than the number of control points, all weight values shall be ignored and a value of 1.0 shall be used.
