A Rust implementation of the book Ray Tracing in One Weekend by Peter Shirley.
Some parts of the next book Ray Tracing: The Next Week also implemented.
Run the program with cargo run --release. You can also give it a JSON configuration file as an argument to change the render settings without having to recompile the program using --config [config.json]. Scene loading is also now supported using --scene [scene.json]. You can also run the program in single-threaded mode by passing --single-threaded for whatever reason. ¯\_(ツ)_/¯
Example:
$ cargo run --release -- --scene res/scenes/cornell.json --config res/config/cornell.json
The following are a few stats on renders done on a PC with an i3-2100 CPU. You can see the performance improvement of the multithreading compared to a single thread. I'll add more to this as I do more renders.
| Multithreaded | Single threaded | |
|---|---|---|
| Cornell box at 800×600 with 10 SPP | 1m 50s | 4m 19s |
| Cornell box at 800×600 with 100 SPP | 21m 05s | 41m 14s |
Here are some stats done on my laptop equipped with an i7-7500U CPU. Seems it's 25% than my old desktop.
| Multithreaded | Single threaded | |
|---|---|---|
| Panda Night at 2524×2524 with 25 SPP | 9h 31m | TBD |
- Implement being able to input random materials via JSON.
- Implement
--verboseoption input to display all messages.
