Package net.minecraft.client.gl

Class VertexBuffer

java.lang.Object

net.minecraft.client.gl.VertexBuffer

All Implemented Interfaces:

AutoCloseable

@Environment(CLIENT)
public class VertexBuffer
extends Object
implements AutoCloseable

Stores vertex data on GPU.

If you don't need to change the geometry, you can upload data once and reuse it every frame. For example, star rendering uses this technique to save bandwidth.

Implementation Note:

This is mostly a wrapper around vertex buffer object (VBO), element buffer object (EBO), and vertex array object (VAO).
