    in , ,

    In today’s world, data is everywhere—and often, it’s overwhelming. Datasets can have hundreds or even thousands of features, many of which are redundant or noisy. Visualising data is an essential skill that allows Data Scientists to effectively highlight structures and relationships that would otherwise remain hidden. This series of tutorials will focus on Principal Component…

    Unity 4D #1: Understanding the Fourth Dimension

    —

    in , , ,

    This is the first part of a series of articles dedicated to extending Unity from 3D to 4D. In this instalment, we will explore the fourth dimension, from its representations in movies and video games, to its more mathematical and geometrical interpretations. At the end of the series, you will learn how to create and…

    in , ,

    This post continues our journey through the Mathematical foundations of iridescence. This time, we will discuss a new way in which material can split light: thin-film interference. This is how bubbles (and car paint) get their unique reflections. You can find the complete series here: A link to download the Unity project used in this…
