public class OGLContour2D
extends BaseContour2D
implements OGLVRMLNode

OpenGL rendering implementation of Contour2D Uses classes from the net.jgeom package to implement trimmed nurbs surface tesselation This class presents methods to retrieve the geometry of a trimming loop for a nurbs patch as an instance of net.jgeom.nurbs.TrimCurve

public OGLContour2D()

Method Details

getTrimCurve

public net.jgeom.nurbs.TrimCurve getTrimCurve()

Returns representation of trimming loop

Returns:

triming geometry as net.jgeom object

getSense

public boolean getSense()

Returns direction of this loop Considering s parameter axis as equivalent to x axis, and t parameter as y axis, return value of true corresponds to a ccw loop, suitable for an outer boundary trimming

Returns:

sense

setQuality

public void setQuality(float q)

setupFinished

public void setupFinished()

Description copied from interface: VRMLNodeType

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. It is then responsible for calling its children's setupFinished.

Specified by:

setupFinished in interface VRMLNodeType

Overrides:

setupFinished in class BaseContour2D

getSceneGraphObject

public org.j3d.aviatrix3d.SceneGraphObject getSceneGraphObject()

got the idea of returning null from OGLCoordinate Get the OGL 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 null representation.
