Class AbstractTarget<R extends Renderable>

Object
  AbstractTarget<R>

All Implemented Interfaces:

Target<R>

Direct Known Subclasses:

FaceTarget, POVRayTarget, PrimitiveTarget

public abstract class AbstractTarget<R extends Renderable>
extends Object
implements Target<R>

superclass for Target implementations that defines some of the required methods using others. Extending it reduces the number of methods that have to be provided by the implementation

AbstractTarget()

Method Summary

void	beginObject(WorldObject object) announces the begin of the draw* calls for a WorldObject.
void	drawBox(Material material, VectorXYZ bottomCenter, VectorXZ faceDirection, double height, double width, double depth) draws a box with outward-facing polygons.
void	drawColumn(Material material, Integer corners, VectorXYZ base, double height, double radiusBottom, double radiusTop, boolean drawBottom, boolean drawTop) draws a column with outward-facing polygons around a point.
void	drawConvexPolygon(Material material, List<VectorXYZ> vs, List<List<VectorXZ>> texCoordLists) draws a convex polygon
void	drawTriangleFan(Material material, List<VectorXYZ> vs, List<List<VectorXZ>> texCoordLists) draws a triangle fan.
void	drawTriangleStrip(Material material, List<VectorXYZ> vs, List<List<VectorXZ>> texCoordLists) draws a triangle strip.
void	finish() gives the target the chance to perform finish/cleanup operations after all objects have been drawn.
void	setConfiguration(Configuration config)

Method Detail

setConfiguration

public void setConfiguration(Configuration config)

Specified by:

setConfiguration in interface Target<R extends Renderable>

beginObject

public void beginObject(WorldObject object)

Description copied from interface: Target

announces the begin of the draw* calls for a WorldObject. This allows targets to group them, if desired. Otherwise, this can be ignored.

Specified by:

beginObject in interface Target<R extends Renderable>

drawBox

public void drawBox(Material material,
                    VectorXYZ bottomCenter,
                    VectorXZ faceDirection,
                    double height,
                    double width,
                    double depth)

Description copied from interface: Target

draws a box with outward-facing polygons.

Specified by:

drawBox in interface Target<R extends Renderable>

faceDirection - direction for the "front" of the box

drawColumn

public void drawColumn(Material material,
                       Integer corners,
                       VectorXYZ base,
                       double height,
                       double radiusBottom,
                       double radiusTop,
                       boolean drawBottom,
                       boolean drawTop)

Description copied from interface: Target

draws a column with outward-facing polygons around a point. A column is a polygon with > 3 corners extruded upwards. The implementation may decide to reduce the number of corners in order to improve performance (or make rendering possible when a perfect cylinder isn't supported).

Specified by:

drawColumn in interface Target<R extends Renderable>

corners - number of corners; null creates a cylinder for radiusBottom == radiusTop or (truncated) cone otherwise

drawTriangleStrip

public void drawTriangleStrip(Material material,
                              List<VectorXYZ> vs,
                              List<List<VectorXZ>> texCoordLists)

Description copied from interface: Target

draws a triangle strip.

Specified by:

drawTriangleStrip in interface Target<R extends Renderable>

vs - vertices of the triangle strip

texCoordLists - one texture coordinate list per texture. Each must have the same length as the "vs" parameter. Can be null if no texturing information is available.

drawTriangleFan

public void drawTriangleFan(Material material,
                            List<VectorXYZ> vs,
                            List<List<VectorXZ>> texCoordLists)

Description copied from interface: Target

draws a triangle fan.

Specified by:

drawTriangleFan in interface Target<R extends Renderable>

Target.drawTriangleStrip(Material, List, List)

drawConvexPolygon

public void drawConvexPolygon(Material material,
                              List<VectorXYZ> vs,
                              List<List<VectorXZ>> texCoordLists)

Description copied from interface: Target

draws a convex polygon

Specified by:

drawConvexPolygon in interface Target<R extends Renderable>

See Also:

Target.drawTriangleStrip(Material, List, List)

finish

public void finish()

Description copied from interface: Target

gives the target the chance to perform finish/cleanup operations after all objects have been drawn.

Specified by:

finish in interface Target<R extends Renderable>
