This post is about a system we devised and set up at home for me to be able to reject all the annoying phone calls I receive during the day from my laptop, without having to go pick up the phone. If you are also working from home like I do (yes, this is another cool option we have at Igalia!) you might find this hack useful. 😀
Hair rendering and simulation can be challenging, especially in real-time. There are many sophisticated algorithms for it (based on particle systems, hair mesh simulation, mass-spring systems and more) that can give very good results. But in this post, I will try to explain a simple and somehow hacky approach I followed in my first attempt to simulate hair (the mohawk hair of the video below) using a mass-spring system.
