Zdog - Celeste snowglobe
------------------------
[Made with Zdog](https://zzz.dog)

Been playing a lot of Celeste. In the eye of the storm with Madeline.

Special sauce  includes bokeh shapes for the snowflakes and light rods, which grow & fade out as the move further from the scene center.

Built with my own vanilla JS (still rocking that ES5) using the <canvas> drawing API. No WebGL. Shapes are rendered with thick lineWidth, giving the illusion of 3D form. A sphere has the same 2D contour as a flat circle. A 3D pill has the same contour of a 2D pill. That's the trick. This is the best engine to render hot dogs and burger patties.

[3D code comes from this Khan Academy lesson](https://www.khanacademy.org/computing/computer-programming/programming-games-visualizations/programming-3d-shapes/a/rotating-3d-shapes). It's great because it only uses simple trig, and no matrix mindbenders.

Yeah it's buggy as heck, but that's the _charm_. It has no concept of intersecting or clipping. Shapes are either rendered before or after one another. Two shapes that occupy the same space will pop over one another when rotated.
