2020 Update : Hello there.
After looking at people making stuff with subpixel lines, I challenged myself to improve that old favorite cart of mine to replace most of its drawing with those sleek lines.
I threw away a lot of things, namely the "math library" I used to have. Turns out that most of the CPU was caused by this and a less optimal management of variables and memory. Cutting down the useless code and the slower practices, I could shave off 10k chars, ~45% of CPU and leave enough CPU time to let the front lines be drawn with subpixel rendering and still take less CPU than the original version. Wow.
Leaving the old version and the old post here. See ya soon!
Hey there, here's another sketch I did a few days ago. After playing a bit with it, I don't have any ideas for it right now. (Also first cart from me with a perspective projection, I took the occasion to fix a bit my vec/mat library.)
Have a nice day!
