Velarium

Name was straight up takes up from Claude with the prompt "Cool canvas names possibly from old times",

Anyhow, this was made a side project after 3-modules into Pikuma's 3-d Graphics Programming course,

I'd just gained ability to render pixels onto screen and was bored with theory, which jump-started a month's journey into making a paint desktop application (ik ik, initializes at 800x600, has single paint colors, so not really something a "cracked guy with high agency" would make)

This how the pixel manipulation wizardry got me feelin' like though

Although the course was in C, i did this in Odin+SDL2 cover Odin exposure Side-Quest

Here is a small demo
