3D Printer Shader Effect – Part 1

Oct 2, 2016

in Shaders, Tutorial, Unity

This tutorial will recreate the 3D printer effect seen in games such as Astroneer and Planetary Annihilation. It’s an interesting effect that shows an object in the process of being created. Despite looking simple, there are many challenges that are far from being trivial. This is a two part tutorials: A link to download the Unity package (code,…
Volumetric Rendering: Signed Distance Functions

in Shaders, Tutorial, Unity

This tutorial explains how to create complex 3D shapes inside volumetric shaders. Signed Distance Functions (often referred to as Fields) are mathematical tools used to describe geometrical shapes such as spheres, boxes and tori. Compared to traditional 3D models made out of triangles, signed distance functions provide virtually infinite resolution, and are amenable to geometric manipulation. The following animation,…
Volumetric Rendering: Surface Shading

in Shaders, Tutorial, Unity

This third instalment on Volumetric Rendering will explain how to shade volumes in a realistic fashion. This essential step is what gives three-dimensionality to the flat, unlit shapes that have been generated so far with raymarching. You can find here all the other posts in this series: The full Unity package is available at the end of this article. 📦

in Shaders, Tutorial, Unity

This is the first part of a Unity tutorial dedicated to Volumetric Rendering, raymarching and signed distance fields. These techniques allow us to overcome the biggest limitation of modern 3D engines, which only let us render the outer shell of an object. Volumetric rendering enables the creation of realistic materials that interact with light in a complex way, such as fog, smoke, water…
LCD Monitor Shader Effect

in Shaders, Tutorial, Unity

This tutorial will show how to create a realistic shader that simulate the look and feeling of LCDs (Liquid Crystal Displays). Developer Monomi Park has recently announced (link) a new update to their game Slime Rancher. One of the most intriguing cosmetic effect that is going to be added is a special LCD shader that makes…
Evolutionary Computation – Part 4

Apr 27, 2016

—

in Machine Learning, Tutorial, Unity

Our journey to harness the power of evolution is coming to an end. In the previous three parts of this tutorial we have constructed a bipedal body and a mutable genome that determines its behaviour. What’s left now is to actually implement the evolutionary computation that will find a successful walking strategy.
Evolutionary Computation – Part 3

in Machine Learning, Tutorial, Unity

When we are looking at a problem through the lens of evolution, we always have to take into account its two faces: the phenotype and genotype. The previous post focused on creating the body of the creature, together with its brain. It is now time to focus on the genotype, which is the way such information is represented, transmitted…
Evolutionary Computation – Part 2

Apr 13, 2016

—

in Machine Learning, Tutorial, Unity

In the first part of this tutorial we have explored what evolutionary computation is, and why it works. The rest of this tutorial will show how to set up a practical example and how to use evolution to solve a real problem. In our case, the problem is teaching a bipedal creature how to keep balance and how to walk…
