Motivations & Learning Outcomes

Prerequisites

Before taking this course, you must have:

  • A basic understanding of programming fundamentals, such as variables, conditionals, loops, and functions.

  • Some basic experience with a C-style programming language syntax (such as C++, Java, C#, Swift, or JavaScript).

Is this course for you?

This course explains the mathematics behind raycasting and takes the student in a journey to create a full raycasting scene with JavaScript and C. To make the most out of this course, you should know the basic elements of any C-style language (JavaScript, Java, C#, etc). If you always wanted to learn how Wolfenstein3D managed to get super amazing graphics and learn how trigonometry and simple math can help you with game development, then this course is definitely for you!

What you'll learn

Course overview and structure

This course covers the full implementation of a raycasting engine using C. The course starts with the explanation of the mathematics behind raycasting and uses JavaScript to create a quick prototype to test the topics covered. Once we are done with the basics, we leave JavaScript and start using the C language to create a complete working version of a raycasting engine, including textured walls, color buffer, and a full discussion on working with C. You'll learn the fundamentals of C, use the SDL library to handle graphics and manipulate color buffer values to make your own raycasting scene.

    Amazing source for whoever wants to actually understand raycasters. The lecturer (Gustavo Pezzi) takes the time to go through the logic and each corresponding line of code. Visual support is also used to help understand each concept.
