w23 / atto Goto Github PK

Useful for:

• raspberry pi
• ios/android external output
• multiple fullscreen desktops

make atto depend only on dlopen/dlsym and not the x11/wayland/gl/vk libraries themselves.
why: make it less dependent on libraries existence and versions

needed for integrated/discrete gpus, and other weird multi-gpu stories

if current extent is less than 1 pixel, then we probably should not render at all?

RPi4 has a newer videocore that uses normal kms/mesa/x11 driver instead of older custom dispmanx API. Currently atto is hardcoded to use dispmanx for rpi, so we need to add explicit support for newer rpi>=4 w/ mesa.

• does regular glx/x11 code just work?
• can we support rpi<4 w/ dispmanx and rpi>=4 in a single binary?

trivial to do, see stameska

Hey,

Found this repo when checking your other OpenSource prj.
I think you are missing a license file here (WTFPL?)

Keep up the good work

• r-lyeh

include/atto/udio.h is broken. Reuse stuff from latest intro tools.
Also, fix thread priorities.

Lightweight text rendering module:

• primitive system font selection (fallback table?)
• platform-specific text rendering backends:
  • windows: GDI TextOut
  • linux: basic freetype

• read file metadata
• read file contents
• write buffer to file

Currently it's just:

1. app starts with some gl context
2. app exits with basically exit()/abort()

Consider something a bit more detailed:

1. app_init_before_gl() <- have a way to read arguments, do some logic to select gl version, fullscreen mode, preferred desktop, etc etc
2. app_init_after_gl() <- after window and gl created
3. app_destroy() <- function to handle app-specific teardown
