Checkpoint 0: Fundamental

Here we will learn polar coordinate, color channel, scale, sin, cos and time: https://gist.github.com/CharStiles/2d8e47d3a61c45b0ac785155e438f06e

Checkpoint 1: Color

Here we learn using palette and combining colors to explore a bit: https://gist.github.com/CharStiles/f07be896021eb109d1b84c564a9a4261

Checkpoint 2: Final

Here we use space transformations to explore a bit: https://gist.github.com/CharStiles/5ebc0fddd938e601da7323ea357d0fdc

🧮 Here is an online graphing calculator, very helpful when writing shaders: https://www.desmos.com/calculator

Creation Prompt! (optional)

Create an object in Unity and color it using shaders in a way that “makes sense”

“Makes sense” can be interpreted broadly. Some options:

  • Make a lava lamp where the inside blobs are driven by a shader.
  • Make some bubbling soup or a cauldron.
  • Make washing machine where the window part is a shader.
  • Make a ghost!

This homework is most of all meant to be a prompt to encourage exploration, which is why its left to broad interpretation.

Next Steps

These are some specific suggestions from me if you want to continue learning but don’t know how to start.

💜Join a community!

Shader.Zone is a a safe and inclusive discord to talk about shaders, tools, generative art, and more! Started by my friends Conner Bell and Patricio Gonzalez Vivo: https://shader.zone/

💙Watch the Twitch stream Curiously Minded!
It was started by two former students of mine who met at a workshop that was just like this one!: https://www.curiouslyminded.xyz/ This is their stream: https://www.twitch.tv/curiouslyminded/

💚Learn the maths from The Book of Shaders

If you haven’t looked at this already, look through it! Its wonderfully paced and has a lot of versatile useful information: https://thebookofshaders.com/
