Class HighPerformanceVertexBufferObject

java.lang.Object

org.andengine.opengl.vbo.VertexBufferObject

org.andengine.opengl.vbo.HighPerformanceVertexBufferObject

All Implemented Interfaces:

IVertexBufferObject, IDisposable

Direct Known Subclasses:

HighPerformanceLineVertexBufferObject, HighPerformanceMeshVertexBufferObject, HighPerformanceRectangleVertexBufferObject, HighPerformanceSpriteBatchVertexBufferObject, HighPerformanceSpriteVertexBufferObject, HighPerformanceTextVertexBufferObject, HighPerformanceUniformColorSpriteVertexBufferObject

public class HighPerformanceVertexBufferObject
extends VertexBufferObject

Compared to a LowMemoryVertexBufferObject, the HighPerformanceVertexBufferObject uses 2x the heap memory, at the benefit of significantly faster data buffering (up to 5x faster!).
