IndexBufferGL3

class IndexBufferGL3(val buffer: Int, val indexCount: Int, val type: IndexType, val session: Session?) : IndexBuffer(source)

Represents an OpenGL index buffer

This class encapsulates an index buffer object (IBO) used for storing index data in GPU memory, which is essential for indexed rendering in OpenGL. It provides methods to bind, unbind, write, read, and destroy the buffer.
