A path tracer which can render realistic lighting in realtime, even on modest hardware. Accumulates light-data for individual pixels over time, and includes a spacial denoiser to reduce artifacts. The following illustrates a Menger sponge, rendered in realtime on a Mackbook Pro 2018 8GB:
Requires Rust 1.50 or later (may work with earlier version, not tested). Does not currently compile on Windows due to missing key bindings, only supported on MacOS and Linux.
In order to build and run the executable, run the following command:
cargo run --releaseIf you only want to build the executable, simply run:
cargo build --releaseSome prebuilt executables exist for MacOS Darwin and Ubuntu Linux. You will find
these in the bin/ directory. Note that these executables must be run from this
root directory, therefore run them with the following command:
./bin/voxel-OSwhere OS corresponds to your operating system.
Shaders are compiled from GLSL to SPIR-V if they are out of date. This is done
using the glslValidator compiler.
The shaders should be up-to-date when you first open this repository, so
installing this executable should not be required. However, if you want to edit
the shaders, make sure that the compiler is installed.
