Member Data Documentation

MATH::CVector4Array m_aControlPoints

Array of ControlPoint values.

Note:

UV ordering is different for the C++ API than it is for scripting. In scripting, a control point array is ordered U-V like so:

(0,0)...(0,cntV-1), (1,0)....(1,cntV-1),(cntU-1,0)...(cntU-1,cntV-1)

However, the order for the C++ API is V-U:

(0,0)...(cntU-1,0), (0,1)....(cntU-1,1)...(0,cntV-1)...(cntU-1,cntV-1)

Since functions like NurbsSurface::Set and X3DObject::AddNurbsSurface expect the U-V order, you must reorder the array before passing it to these functions. See cpp_understand_UV_Ordering UV Ordering for a sample conversion function.

LONG m_lNbUControlPoints

Number of ControlPoints in U

LONG m_lNbVControlPoints

Number of ControlPoints in V

CDoubleArray m_aUKnots

U Knot values

CDoubleArray m_aVKnots

V Knot values

bool m_bUClosed

Specify if the surface is closed in U direction.

bool m_bVClosed

Specify if the surface is closed in V direction.

LONG m_lUDegree

Specify if the degree of the nurbs surface in U.

LONG m_lVDegree

Specify if the degree of the nurbs surface in V.

siKnotParameterization m_siUParameterization

Parameterization factor of the nurbs surface in U.

siKnotParameterization m_siVParameterization

Parameterization factor of the nurbs surface in V.
