Class VBOBuilder

java.lang.Object

org.jzy3d.plot3d.primitives.vbo.builders.VBOBuilder

All Implemented Interfaces:

IGLLoader<DrawableVBO>

Direct Known Subclasses:

CubeVBOBuilder, ShaderMeshVBOBuilder, ShaderWaterfallVBOBuilder, VBOBuilderListCoord3d

public abstract class VBOBuilder
extends Object
implements IGLLoader<DrawableVBO>

The VBOBuilder is responsible for sizing a FloatVBO, filling it with vertex coordinates and colors properties, and configure a DrawableVBO with filled buffer. The builder will be called via method

invalid @link

load()

once GL context is ready to store geometry in GPU for the given DrawableVBO instance. This is where builder actually draw the object by setting coordinates, colors, and rendering parameters. A Quality setting can be given to configure GL properties of the drawable:
