#2This is a weekly educational challenge thread where /3/ will be tested in their knowledge and/or study subjects pertaining to 3DCG.This time, the question is about lighting and how it works.OK.We (hopefully)know that real-time basic light works depending on the surface normal, the light direction, and how parallel they are to each other.For this challenge, you have to study and understand/come up(or just state if you already know) with a formula(or logic using words) for specular highlight. If you're trying to come up with a formula, here's a hint: 3 values are essential:>1: light direction>2: view direction>3: surface normal facing directionKnowing what's under the hood instead of making pixie dust is always good, we're trying to be professionals! It's ok if you don't post anything, the fact that you're studying alone makes you more cool, authentic and pro!Stay productive /3/!
