Part 2 is out! https://scratch.mit.edu/projects/403811864 This is part one of my raymarching tutorial — Objects. It is the first raymarching tutorial on Scratch. If you are unfamiliar with raymarching, it is the process of “marching” “rays” to generate pictures of objects. Because Scratch is so slow, it is better to use turbo mode while rendering. And I forgot to say in the tutorial: SDE stands for Signed Distance Estimate. It’s basically normal distance, except it is negative when inside the object. If you are confused look at my example sprite. Part 2 will be lighting and shadows.
