Method Details

createNurbsSurface

public static final Surface createNurbsSurface(List<List<Vector4f>> controlPoints,
 List<Float>[] nurbKnots,
 int uSegments,
 int vSegments,
 int basisUFunctionDegree,
 int basisVFunctionDegree)

This method creates a NURBS surface. The created mesh is smooth by default.

Parameters:

controlPoints - space control points

nurbKnots - knots of the surface

uSegments - the amount of U segments

vSegments - the amount of V segments

basisUFunctionDegree - the degree of basis U function

basisVFunctionDegree - the degree of basis V function

Returns:

an instance of NURBS surface

createNurbsSurface

public static final Surface createNurbsSurface(List<List<Vector4f>> controlPoints,
 List<Float>[] nurbKnots,
 int uSegments,
 int vSegments,
 int basisUFunctionDegree,
 int basisVFunctionDegree,
 boolean smooth)

This method creates a NURBS surface.

Parameters:

controlPoints - space control points

nurbKnots - knots of the surface

uSegments - the amount of U segments

vSegments - the amount of V segments

basisUFunctionDegree - the degree of basis U function

basisVFunctionDegree - the degree of basis V function

smooth - true for a smooth mesh

Returns:

an instance of NURBS surface

getControlPoints

public List<List<Vector4f>> getControlPoints()

getUControlPointsAmount

public int getUControlPointsAmount()

This method returns the amount of U control points.

Returns:

the amount of U control points

getVControlPointsAmount

public int getVControlPointsAmount()

This method returns the amount of V control points.

Returns:

the amount of V control points

getBasisUFunctionDegree

public int getBasisUFunctionDegree()

This method returns the degree of basis U function.

Returns:

the degree of basis U function

getBasisVFunctionDegree

public int getBasisVFunctionDegree()

This method returns the degree of basis V function.
