Constructor Detail

Polygon

public Polygon()

Initializes an empty Polygon with face status defaulting to true, and wireframe status defaulting to false.

Method Detail

draw

public void draw(javax.media.opengl.GL2 gl,
                 javax.media.opengl.glu.GLU glu,
                 Camera cam)

Description copied from class: AbstractDrawable

Call OpenGL2 routines for rendering the object.

Specified by:

draw in interface IGLRenderer

Specified by:

draw in class AbstractDrawable

Parameters:

gl - GL2 context

glu - GLU context

cam - a reference to a shooting Camera.

applyPolygonModeLine

protected void applyPolygonModeLine(javax.media.opengl.GL2 gl)

applyPolygonModeFill

protected void applyPolygonModeFill(javax.media.opengl.GL2 gl)

polygonOffseFillEnable

protected void polygonOffseFillEnable(javax.media.opengl.GL2 gl)

polygonOffsetFillDisable

protected void polygonOffsetFillDisable(javax.media.opengl.GL2 gl)

add

public void add(Point point)

Add a point to the polygon.

getBarycentre

public Coord3d getBarycentre()

Description copied from class: AbstractDrawable

Return the barycentre of this object, which is computed as the center of its bounding box. If the bounding box is not available, the returned value is Coord3d.INVALID

Overrides:

getBarycentre in class AbstractDrawable

Returns:

the center of the bounding box, or Coord3d.INVALID.

get

public Point get(int p)

getAll

public List<Point> getAll()

size

Description copied from class: AbstractDrawable

Return the distance of the object center to the Camera's eye.

Specified by:

getDistance in interface ISortableDraw

Overrides:

getDistance in class AbstractDrawable

getShortestDistance

public double getShortestDistance(Camera camera)

Specified by:

getShortestDistance in interface ISortableDraw

Overrides:
