All Implemented Interfaces:

BSPTreeTraverseListener

public class SimpleBSPRenderer

extends ShadedSurfacePolygonRenderer

implements BSPTreeTraverseListener

The SimpleBSPRenderer class is a renderer capable of drawing polygons in a BSP tree and any polygon objects in the scene. No Z-buffering is used.

Constructor Detail

SimpleBSPRenderer

public SimpleBSPRenderer(Transform3D camera,
                         ViewWindow viewWindow)

Creates a new BSP renderer with the specified camera object and view window.

Method Detail

startFrame

public void startFrame(java.awt.Graphics2D g)

Description copied from class: PolygonRenderer

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

Overrides:

startFrame in class FastTexturedPolygonRenderer

endFrame

public void endFrame(java.awt.Graphics2D g)

Description copied from class: PolygonRenderer

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

Overrides:

endFrame in class ShadedSurfacePolygonRenderer

draw

public void draw(java.awt.Graphics2D g,
                 BSPTree tree)

Draws the visible polygons in a BSP tree based on the camera location. The polygons are drawn front-to-back.

visitPolygon

public boolean visitPolygon(BSPPolygon poly,
                            boolean isBack)

Description copied from interface: BSPTreeTraverseListener

Visits a BSP polygon. Called by a BSPTreeTraverer. If this method returns true, the BSPTreeTraverer will stop the current traversal. Otherwise, the BSPTreeTraverer will continue if there are polygons in the tree that have not yet been traversed.

Specified by:

visitPolygon in interface BSPTreeTraverseListener
