org.oscim.renderer.NativeBufferPool

public class NativeBufferPool
extends Pool<org.oscim.renderer.NativeBufferPool.BufferItem>

Pool to retrieve temporary native buffer on GL-Thread: This pool ensures to not use the same buffer to upload data twice within a frame. - Contrary to what the OpenGL doc says data seems *not* to be always* copied after glBufferData returns... - Somehow it does always copy when using Android GL bindings but not when using libgdx bindings (LWJGL or AndroidGL20)
