Recently, I've delved into the world of Ar.js and have been attempting to incorporate environmental occlusion. Despite my efforts in searching for tutorials on this specific topic within ar.js, I haven't had any luck finding concrete examples or practical demonstrations. Most resources seem to provide theoretical explanations of occlusion but lack application. Can someone offer guidance or direct me towards a reliable source for learning how to achieve environmental occlusion using ar.js? Any help would be greatly appreciated!
