◈ ◈ ◈ Series overview ◈ ◈ ◈ Part 1: https://scratch.mit.edu/projects/973984754 Part 2: https://scratch.mit.edu/projects/974950082 ◈ ◈ ◈ Notes ◈ ◈ ◈ If you look up fill rules, you'll find that the spelling of "nonzero" and "even-odd" varies a lot. In SVG, the value of the property fill-rule is either "nonzero" or "evenodd". In this project though, I'm not talking about SVG code specifically, so I chose to use the more readable spelling "even-odd". That is also the most common spelling in non-coding texts, such as the documentation for Adobe Illustrator. ◈ ◈ ◈ Credits ◈ ◈ ◈ The squirrel and most of the sounds are from the Scratch Library, although I have edited several of them.

The cuckoo sound was made in BeepBox as well. ◈ ◈ ◈ Further reading ◈ ◈ ◈ The SVG fill-rule definition: https://www.w3.org/TR/SVG2/painting.html#WindingRule Wikipedia has more general information: https://en.wikipedia.org/wiki/Nonzero-rule https://en.wikipedia.org/wiki/Even-odd_rule Advanced vector editors such as Adobe Illustrator let you pick fill rule and choose winding direction by the click of a button: https://helpx.adobe.com/illustrator/using/combining-objects.html#apply_fill_rules_to_compound_paths Interestingly, "nonzero" and "even-odd" aren't the only rules. For example, OpenGL has three additional rules (positive, negative, ≥ 2) you can choose. From what little I have read, those rules appear to be used for 3D graphics only, but I could be wrong. https://www.songho.ca/opengl/gl_tessellation.html
