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).

      public void upload(BufferBuilder.BuiltBuffer buffer)
      Uploads the contents of buffer to GPU, discarding previously uploaded data.

      The caller of this method must bind this vertex buffer before calling this method.
