The Art of Procedural Noise #SoME3

Deep dive into the topic of procedural noise from a unique perspective. We explore its origins, properties, applications, and more! Resources for further exploration: - [1], [2] - Great starting point if you want to explore ideas of the frequency domain. Both monographs are focused on computer vision. However, those foundations apply to a wide range of fields. Besides notes, there are recorded lectures, and Professor Nayar is an excellent teacher! - [3] - This entire book is dedicated to procedural generation and contains much information about noise, among other interesting topics. However, it’s mathematics isn’t “self-contained“. - [4] - This book also introduces the frequency domain in the context of computer graphics. It also contains the foundations of mathematics that you need to understand those concepts deeper. If you’re comfortable with at least high-school math, this book is an excellent starting point. - [5] - Formal introduction to procedural noise and ways we evaluate it - a bit tough read, though :) [1] Image Processing I, Shree K.

Soundtrack by Ben Elson - I’ve used tracks from his album Orthosie - - I’ve used some assets from digital libraries. Music, SFX comes from Epidemic Sound, and some real-life shots come from Envato Elements. Epidemic Sound: (affiliate)
