1. Introduction Released on August 6, 2012, OpenGL 4.3 marked a significant maturation of the modern OpenGL pipeline. While its predecessor, OpenGL 4.2, introduced shader-based image load/store and tessellation, version 4.3 focused on three critical pillars: GPU-accelerated compute shaders , efficient texture manipulation , and robust debugging and validation . // Dispatch compute work groups (512/16 = 32
