# 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](https://pikuma.com/courses/learn-3d-computer-graphics-programming),
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
