Class Drawing

java.lang.Object

com.bonzaiengine.drawing.Drawing

All Implemented Interfaces:

ITransformable, IDestroyable, IBoundable, ICullable

public final class Drawing
extends java.lang.Object
implements IDestroyable, ITransformable, ICullable

A Drawing is a container for simple line shapes: Lines, LineStrip, Circle, Arc, Ellipse, ...
ShapeGroup can be used to create a tree container.

It is cullable (and compatible with Visibility), positionable (ITransformable) and destroyable (holds hardware data).

Typical usage:

 // Creation
 Drawing drawing = [...]; // Manually create or use reader:
                          // new DxfReader().read(new ReaderSettings(new Stream("drawing.dxf")))
 // Update
 visibility.cull(drawing); // Optional culling
 
 // Render
 DrawingRenderer.render(renderer, drawing); // between renderer.start/end
 
 // Destruction
 drawing.destroy(gl);
