Constructor Detail

PgBezierCurve

public PgBezierCurve(int aVertexDim)

Method Detail

init

public void init()

Description copied from class: PgPolygon

Initialize and reset instance variables after call to super.init().

Overrides:

init in class PgPolygon

copy

public void copy(PgGeometry aGeom)

Description copied from class: PgPolygon

Copy instance variables by duplication, not by copying a reference.

Overrides:

copy in class PgPolygon

getControlPoint

protected PdVector[] getControlPoint()

getNumControlPoints

public int getNumControlPoints()

setNumControlPoints

public void setNumControlPoints(int aNum)

Set number of control points. All controlPoint allocation should be done in this method.

getDegree

protected int getDegree()

setDegree

protected void setDegree(int aDegree)

addControlPoint

public void addControlPoint(PdVector aPoint)

setControlPoint

public void setControlPoint(int anIndex,
                            PdVector aPoint)

setNumVertices

public void setNumVertices(int aNum)

Description copied from class: PgPointSet

Allocate given number of vertices, and allocate normals, colors etc. if they already exist. Internally, there may exist more vertices than requested serving as buffer and to reduce allocation times.

Overrides:

setNumVertices in class PgPointSet

computeVertices

protected void computeVertices()

eval

public void eval(PdVector v,
                 double t)
