This is the second part of the online course dedicated to the modelling and simulating of epidemics. If you are interested in understanding how Mathematicians, Programmers and Data Scientists are studying and fighting the spread of diseases, this series of posts is what you are looking for.
In the second part, we will focus on ways to simulate epidemics. While the code here presented is in C# and runs in Unity, the knowledge can be applied to virtually any other language or engine.
This online course is inspired by the recent COVID-19 pandemic. Now more than ever we need skilled and passionate people to focus on the complex subject of Epidemiology. I hope these articles will help some of you to get started.
All the revenue made from this article through Patreon will be donated to the National Emergencies Trust (NET) to help those most affected by the recent coronavirus outbreak. If you have recently become a patron for this reason, get in touch and I will add your contribution.
In this fifth post, we will recreate the shimmering reflections that are typically seen on sand dunes.
Shortly after the publication of this series, Julian Oberbeck and Paul Nadalack made their own attempt at recreating a Journey-inspired scene in Unity. You can see in the thread below how they have improved the glitter reflection to have more temporal coherence. You can read more about their implementation on IndieBurg’s article Mip Map Folding.
Creating believable caustics reflections is something that most technical artists have attempted achieving at some point in their career. If you are a game developer, one of the main reasons to use Twitter is the endless stream of inspiration it can provide. A few days ago Florian Gelzenleuchter (kolyaTQ on twitter) posted a GIF of a caustics effect created in Unity using shaders. The post (below) quickly reached 1.5K likes, showing a genuine interest for this type of content.
Want to have sweet caustics? Here you go:
-> Get a caustics texture (bw) -> unpack in shader twice and pan at different speed/size -> blend with min(tex2, tex1) -> Enjoy!
