  • Fading Sprites in Unity

    Fading Sprites in Unity

    in , ,

    This tutorial shows how to extend the class SpriteRenderer  to support intuitive, painless fading transitions. Despite referring to sprites, this approach can be used to easily animate any property of a game object in Unity. The link for the script used in this tutorial is at the end of the post.

    This tutorial shows how to automatically generate simplified colliders for 3D models imported into Unity. The tutorial uses Google SketchUp as an example, but its knowledge and code is agnostic to whichever modelling tool you are using.

    In a previous post, How To Integrate Arduino With Unity, we have shown how data can be sent and received through the serial port. The main problem encountered was dealing with the latency and the delays that communicating across different devices introduces. The solution proposed in that tutorial used a coroutine; decoupling the device communication from the game logic attenuates the…

    This is the second part of Fractals 101, a series of tutorial dedicated to fractals. This post will investigate two popular fractals: the Mandelbrot set and its 3D cousin, the Mandelbulb.

  • Volumetric Rendering: Signed Distance Functions

    Volumetric Rendering: Signed Distance Functions

    —

    in , ,

    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,…

    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 , ,

    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

    LCD Monitor Shader Effect

    in , ,

    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

    Evolutionary Computation – Part 4

    —

    in , ,

    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.
