eray
Simple TUI shader graph editor and OpenGL viewer with raytraced screenshot capabilities.
Best-case scenario objectives
ISIM:
- Object loading
- Generic graph-based computation pipeline
- Raytracer using the shader graph
POGL:
- Scene conversion for OpenGL {should already work}
- Shaderlib port to OpenGL shaders
- Live OpenGL view
TIFO:
- Post-processing pipeline setup {seemingly trivial}
- Library of post-processing effects
Bonus:
- .eray parsing and dumping {dumping missing}
- TUI editor
Running
An example graph is already defined in src/main.rs, just run the following
command in your shell (with the rust toolchain installed) and the output color
texture will be saved as color.ppm.
cargo run.eray shader files
Shader graphs are meant to be fully representable as (and therefore storable to
and loadable from) .eray files following the grammar defined in
src/lib/pest/grammar.pest.
