Raito

Raito Rendering engine

Raito RenderView UI with a sphere shaded with normals

Dependencies

• The GUI is created with egui and eframe
• The documentation runs on mkdocs with several plugins required :
  • pip install mkdocs-material (theme)
  • pip install mkdocs-glightbox (to zoom on images)

Here are also additional dependencies :

• log : logging library
• env_logger : used to setup the log level
• clap : to parse command line argumments
• rand & rand_chacha : random numbers
• quick-xml : Read XML files

Run

1. Install rust
2. You might need to install specific packages for eframe :

• Linux : sudo apt-get install libxcb-render0-dev libxcb-shape0-dev libxcb-xfixes0-dev libxkbcommon-dev libssl-dev
• Fedora : sudo dnf install clang clang-devel clang-tools-extra libxkbcommon-devel pkg-config openssl-devel libxcb-devel gtk3-devel atk fontconfig-devel

3. Build and run : cargo run --release
4. To build and run doc launch : python -m mkdocs serve. That will serve the site on localhost

Also you can use the crun utility script :

• crun -b : build and executes
• crun : find the exectuable and launch it directly
• crun $args : also works if you want to pass arguments to the executable

Command Line Arguments

Usage: raito [OPTIONS]

Options:
  -l, --log-level <LOG_LEVEL>  Verbosity level [default: info] [possible values: debug, info, warning, error]
  -t, --tests                  Execute tests

Next steps

• Finish first version of Raito :
  • Add real progressive rendering
  • Implement polymesh nodes for complete set of geometry
  • Implement BVH
• Start second iteration :
  • Focus on improving the UI. The end goal is to make an easy-to-use tool for shader development with best performances possible
  • Rework on the code base with what I learned in Rust
  • Provide node graph to build scenes
  • ...
• Third iteration will focus on shader development
• Fourth iteration will focus on developping new iterators and optimizations, like photon mapping, VCM, etc
