QuasiSpace by The Orz
128 bytes linux procedural graphics
for Outline demoparty 2021
requirements:
- 32 bits /dev/fb0 with supported resolution
- framebuffer set to display resolution
how to run:
- switch to console with Ctrl+Alt+F2 (Ctrl+Alt+F1 to switch back to X)
- check /dev/fb0 is writable to you (or launch with sudo to bypass this step)
- check /dev/fb0 current resolution with fbset tool
- run `clear`
- run the appropriate binary
change graphical terminal resolution:
- check supported resolution with "vbeinfo" in GRUB command prompt
- "GRUB_GFXMODE=WxH" in /etc/default/grub (where W/H is a value)
- sudo update-grub
A mixture of C and ASM as an experiment / POC. The graphics code is all C and all init code is 32 bits ASM (based on Lintro by frag/fsqrt). The code without ELF headers is ~80 bytes and ~52 bytes without init. The party version has all data / code removed from the ELF header to comply with party rules.
code by grz built with GCC v11
greetings to all sizecoders
