In this video we'll practice basic JavaScript by implementing an optical illusion called the Café Wall Illusion or the Shifted Chessboard Illusion.
To code this illusion we'll be using the canvas element. The canvas element is an HTML element that allows for dynamic, scriptable rendering of 2D shapes and graphics. We use JavaScript to draw on the canvas.
By coding along you'll learn about variables and loops in JavaScript. You'll also learn a few things about drawing shapes with different colors. At the end I'll teach you how to negate the effect so the illusion doesn't happen anymore. The code is quite basic, but the end result is quite interesting so I think you'll enjoy this no mater if you are a beginner or advanced.

![A Virtual World - JavaScript Course: Lesson 1 / 11 [Spatial Graphs]
Welcome to Phase 2 of my Self-Driving Car Course!
You dont need to have watched Phase 1 to start this course. A Virtual World is a standalone course where well construct a virtual environment entirely from the ground up. Get ready to use basic HTML, CSS, and JavaScript to craft this world where self-driving cars (or anything you desire, like Pokémon :-D) can roam freely. Our primary focus will be on generating this dynamic world, with the integration of self-driving car code coming at the end.
This course serves as preparation for Phase 3, Understanding AI, where well delve into neural networks and other advanced AI techniques. By the end of Phase 3, youll comprehend the inner workings of neural networks, the importance of hidden layers, and more. But to get there, we need this sophisticated world to create complex scenarios, as our previous one was too simplistic. So, if youre eagerly anticipating neural networks, please be patient and enjoy Phase 2 in the meantime.
In this phase, youll acquire valuable skills, including mathematics, algorithms, programming, and design—skills that greatly benefited me during my PhD and my time at Microsoft. Im confident theyll boost your career as well.
Heres what youll learn:
* Building a spatial graph from scratch and creating an editor with a dynamic viewport.
* Understanding the mathematics and logic behind user-friendly interfaces in modern software.
* Generating road borders, buildings, and trees using geometry and creating a 3D illusion.
* Implementing road markings to prepare for advanced self-driving challenges.
* Enhancing the world editor for user convenience and maximizing auto-generated content.
* Loading real-world data from openstreetmap for city-based simulations.
* Creating a minimap for navigation in expansive worlds.
Have Fun! :-)
