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,

invalid reference 
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).
