Studying for a Tech Interview Sucks, so Here's a Cheat Sheet to Help

This cheatsheet is written by @TSiege. You can check the original version of cheatsheet at link

This list is meant to be both quick guide and reference for further research into these topics. It's basically a summary of that comp sci course you never took or forgot about, so there's no way it can cover everything in depth. It also will be available as a gist on Github for everyone to edit and add to.

Data Structure Basics

Please consider using http://lygia.xyz instead of copy/pasting this functions. It expand suport for voronoi, voronoise, fbm, noise, worley, noise, derivatives and much more, through simple file dependencies. Take a look to https://github.com/patriciogonzalezvivo/lygia/tree/main/generative

Generic 1,2,3 Noise

float rand(float n){return fract(sin(n) * 43758.5453123);}

float noise(float p){
	float fl = floor(p);
  float fc = fract(p);

	# Combined all static libaries in the current directory into a single static library
	# It is hardcoded to use the i386, armv7, and armv7s architectures; this can easily be changed via the 'archs' variable at the top
	# The script takes a single argument, which is the name of the final, combined library to be created.

	# For example:
	# => combine_static_libraries.sh combined-library
