Remda

Learn Ray Tracing in One Weekend series using Rust.

Yet another naive and pure software ray tracing renderer.

example rtnw_4_3, 1024 sample, 8 depth, 1920x1080, 22min

example rtnw_7_4_2, 4096 sample, 8 depth, 1500x900, 15min

example rtnw_8_2, 10240 sample, 10 depth, 1000x1000, 1h20m

example rtnw_9_2, 10240 sample, 10 depth, 1000x1000, 1h30m

example rtnw_10, 10240 sample, 10 depth, 1000x1000, 2h30m

Run

Remda is a library crate, but you can run built-in examples(from the book series) to try it.

Use cargo run --example to get examples list, then choose one to run.

For example, to get final scene in section 13.1 of Ray Tracing in One Weekend, run

cargo run --example rtow_13_1 --release

Wait about 1s(according to your machine's CPU performance), you will get a rtow_13_1.ppm in current dir, that's your result.

If you want a bigger and clear image, adjust height(), depth and samples() parameter in example source file and re-run.

You can also try other examples if you want.

PS: Pure software ray tracing takes a long time to render, be patient.
