in Programming, Shaders, Tutorial, Unity

This tutorial explains how to pass arrays to shaders in Unity. This feature has been present for a long time, but is mostly undocumented. Unity 5.4.0 Beta 1 will introduce a proper API to pass arrays to shaders; this technique however will work with any previous version. If you are using Unity 5.4+, please refer to the Arrays & Shaders…
The Secrets of Colour Interpolation

in Maths, Tutorial, Unity

This post discusses about the tricky problem of colour interpolation, and explores possible solutions. Many software and engines offer read-to-use functions to interpolate colours. In Unity, for instance, Color.Lerp is available and does its job pretty nicely. Use the interactive swatch below to see how Color.Lerp works. There’s nothing wrong in using these functions, as long as you know…
Accessibility Design: Color Blindness

in Shaders, Tutorial, Unity

The filter This tutorial will teach you how to create and use post-processing effects which simulate how colour blind players might experience your Unity game. One of my most anticipated games is The Witness; since it uses so many vibrant colours, it will be used as an example in this tutorial. This is how a player affected by red-green colour blindness (protanopia) might see…

in C#, Shaders, Tutorial, Unity

This tutorial will teach you how to create non euclidean cubes in Unity, giving the illusion that each face is a door onto another dimension. This post is part of a series of tutorials on impossible geometries. This effect can be seen in many game, most notoriously Antichamber which uses it extensively. You can download the Unity package here.
