OGLNurbsPatchSurface

public OGLNurbsPatchSurface()

Method Details

getGeometry

public org.j3d.aviatrix3d.Geometry getGeometry()

Description copied from interface: OGLGeometryNodeType

Returns a OGL Geometry node that represents this piece of geometry. If no geometry is available, then return null.

Specified by:

getGeometry in interface OGLGeometryNodeType

Returns:

The geometry needed to represent this object

getSceneGraphObject

public org.j3d.aviatrix3d.SceneGraphObject getSceneGraphObject()

Description copied from interface: OGLVRMLNode

Get the OpenGL scene graph object representation of this node. This will need to be cast to the appropriate parent type when being used.

Specified by:

getSceneGraphObject in interface OGLVRMLNode

Returns:

The OpenGL representation.

getNurbsImpl

public net.jgeom.nurbs.BasicNurbsSurface getNurbsImpl()

Specified by:

getNurbsImpl in interface VRMLBREPSurfaceNode

Overrides:

getNurbsImpl in class BaseNurbsPatchSurface

Returns:

setupFinished

public void setupFinished()

Description copied from class: BaseNurbsPatchSurface

Notification that the construction phase of this node has finished. If the node would like to do any internal processing, such as setting up geometry, then go for it now.

Specified by:

setupFinished in interface VRMLNodeType

Overrides:

setupFinished in class BaseNurbsPatchSurface

uniformKnotVector

public float[] uniformKnotVector(int order,
 int dimension)

Returns a uniform vector of knot values (clamped) for a spline of order (order=polynomial degree + 1; order=4 are cubic splines) and dimension (dimension = number of control points) returns for parameter range 0 to 1 follows definition of uniform knot from "The Nurbs Book" (L. Piegl & W Tiller, 2nd ed) section 2.4

Parameters:

dimension -

Returns:

float[] array of knot values

render

public void render()

Specified by:

render in interface VRMLBREPNodeType

set_renderer

public void set_renderer(Object renderer)

Specified by:

set_renderer in interface VRMLBREPNodeType

isSolid

public boolean isSolid()

Description copied from class: BaseNurbsPatchSurface

Get the value of the solid field.

Specified by:

isSolid in interface VRMLGeometryNodeType

Overrides:

isSolid in class BaseNurbsPatchSurface

Returns:

true This object is solid (ie single sided)
