Class DrawableVBO

java.lang.Object

org.jzy3d.plot3d.primitives.AbstractDrawable

org.jzy3d.plot3d.primitives.vbo.drawable.DrawableVBO

All Implemented Interfaces:

IGLBindedResource, IGLRenderer, ISortableDraw

Direct Known Subclasses:

BarVBO, ScatterVBO

public class DrawableVBO
extends AbstractDrawable
implements IGLBindedResource

A DrawableVBO is able to efficiently draw a large collection of geometries. The user must provide a loader that will be later called when the GL context requires loading the VBO data in GPU memory. The loader might freely make settings on the drawable as it is called with a reference to the DrawableVBO is will be loading data into. One can separate data and appearance by setting geometry settings out of loading process. DrawableVBO shape1 = new DrawableVBO(new MemoryVBOLoader(getScatter(size))); shape1.setGeometry(GL.GL_POINTS); shape1.setColor(Color.WHITE);
