Topographical Maps in Unity: Edge Detection

This tutorial will teach you how to recreate a very popular effect in games: topographical maps.

This is a two-part series, which will cover all the necessary aspects—from the Maths to the shader code—to make this possible:

In this second part, we will focus on the edge detection algorithm that will be used to draw the contours of the terrain.

A link to download the full Unity package is also available at the end of the tutorial.

How to Create a 360° Video in Unity

This is the second part of the online series dedicated to the creation of 360° videos in Unity. With this course, you will be able to produce 360° videos trailers for your VR games that can be played with YouTube, and even produce effective educational content like the one below.

This online course is split into two modules. The first one will focus on how to create the videos in Unity, and is already available:

The second module will focus on editing the videos, and will be released at a later time:

An Introduction to 360° Videos

This online series will cover everything you need to know about 360° videos; from how to create them in Unity, to how to edit them in Premiere Pro in a format compatible with YouTube. Whether you want to create an immersive 360° video, or a trailer for your VR game, this is the tutorial for you. You will also learn how to create and edit Ambisonic tracks with Head-Lock stereo audio, which is perfect for 360° videos with narrated voiceovers.

If you are unfamiliar with 360° videos, you can have a look at one that I have recently created, which features a journey through all of the discovered exoplanets.

This online course is split into two modules. The first one will focus on how to create the videos in Unity, and is already available:

The second module will focus on editing the videos, and will be released at a later time:

Simulating Epidemics

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.

You can read the rest of this online course here:

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.

Journey Sand Shader: Glitter Reflection

This is the fifth part of the online series dedicated to Journey Sand Shader.

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.
