1 * During the development of the GDice app ( the log will be posted soon ), I was experimenting ways to display numbers
2 * One particular way interested me that has the nostalgic feeling, called [[Nixie Tube>>https://en.wikipedia.org/wiki/Nixie_tube]]
3 ** End up not using it, but it's a good test
4 ** Built using [[Autodesk Fusion 360>>https://www.autodesk.com/products/fusion-360/students-teachers-educators]]
5 *** Solid modeling , will not be polygon efficient for game rendering
6 *** Rendered as spritesheet, as f360 has a pretty easy to tune rendering system that's almost photo realistic
7 ** Result put in : [[Nixie Tube Spritesheet>>https://opengameart.org/content/nixie-digits-spritesheet]]
8 ** Packed using [[Texturepacker's free version>>https://www.codeandweb.com/texturepacker]](((

13 * Phaser P5 not working somehow needs investigate
14 * Somehow can only use raw API
