[video] Animated Flag Part 2 - Advanced Materials - Episode 27

  • part 2 of the animated flag series extends the effect from the previous video
  • adds support for allowing the flag to be rotated
  • additionally shows how to recalculate the normals for improved lighting

[video] Why can't you multiply vectors?

  • the talk presents an overview of linear algebra
  • covering topics from the basics of vectors, complex numbers, operations between vectors, and more
  • shows how intuition developed connects to geometric algebra

Machine Learning for Game Devs: Part 1

  • the blog post introduces a new series about machine learning that aims to connect different disciplines
  • provides an introduction to machine learning and shows how it can be expressed in shader code

Study Notes On The Marschner Hair Shading Model

  • the blog post describes the The Marschner Hair Shading Model
  • focuses on high-level information and develops an intuition for the model
  • additionally provides corrections and extensions for ideas from the original paper

GM Shaders Mini: Tonemaps

  • the article presents the importance of tone mapping to reduce color clamping
