Constructor Detail

PolygonRenderer

public PolygonRenderer(Transform3D camera,
                       ViewWindow viewWindow)

Creates a new PolygonRenderer with the specified Transform3D (camera) and ViewWindow. The view is cleared when startFrame() is called.

PolygonRenderer

public PolygonRenderer(Transform3D camera,
                       ViewWindow viewWindow,
                       boolean clearViewEveryFrame)

Creates a new PolygonRenderer with the specified Transform3D (camera) and ViewWindow. If clearViewEveryFrame is true, the view is cleared when startFrame() is called.

Method Detail

getCamera

public Transform3D getCamera()

Gets the camera used for this PolygonRenderer.

startFrame

public void startFrame(java.awt.Graphics2D g)

Indicates the start of rendering of a frame. This method should be called every frame before any polygons are drawn.

endFrame

public void endFrame(java.awt.Graphics2D g)

Indicates the end of rendering of a frame. This method should be called every frame after all polygons are drawn.

draw

public boolean draw(java.awt.Graphics2D g,
                    Polygon3D poly)

Transforms and draws a polygon.
