In this tutorial, we will explore the core concepts of Vertex Arrays, Vertex Buffers, and Element Buffer Objects in Modern OpenGL. Through a detailed step-by-step walkthrough, you will gain a comprehensive understanding of these essential elements. Once we've mastered these concepts, we'll apply our newly acquired knowledge to render a surface chart step by step, from a flat grid to dynamic rotations in 3D.
