Encoding the Scene

Jan 04, 2022

Updates

  • Recieved a few issues and pull requests, thanks Christian and Felipe!
  • Improved the README with basic hacking instructions

  • Considered Zig this weekend, will stick with C for now
  • Didn't get the summary video out this week!

Encoding C structs from Scheme

  • Structs are laid out contiguously
  • Do we need to worry about memory alignment?
  • What about nested data?

Tasks

DONE Try to finish instantiating a test scene in C (try Felipe's fix)

DONE Figure out how to create the C struct representation for scene objects in Scheme

DONE Get the basic-gfx.scm example working

TODO Transmit drawing instructions to renderer thread in some form (SDL event?)

TODO Make sure that we can re-eval the Scheme code to update the live preview

TODO Render the completed image to a .png file

TODO Load and render an image file

Next Steps

TODO Figure out why scene flipping doesn't work (event problem?)

TODO Transmit drawing instructions to renderer thread in some form

TODO Make sure that we can re-eval the Scheme code to update the live preview

TODO Render the completed image to a .png file

TODO Load and render an image file
