Create Galaxy

https://creategalaxy.com

Create awesome procedurally generated galaxies.

Known Issues

• 2d canvas globalCompositeOperation and filter are not supported in Safari (mobile and desktop). They are also very slow in Firefox.

So why not WebGL? 🤔

There was an experiment to make this render on WebGL (using pixi-js v5) rather than a 2D canvas. It enabled having blending modes and filters in the unsupported browsers with better performance everywhere. However, there were problems:

• Couldn't get a good-looking gaussian blur filter.
• WebGL blend modes are limited.

My experience with WebGL is limited so it might be achieved afterall. Contributions to try and get it right are welcome.
