Developing

Muon uses Bazel as its build system, which you can install via these instructions. The most recently tested version is bazel 3.7.1.

To build, run:

$ bazel build //muon

You can also use bazel-watcher to rebuild automatically after changes.

To execute a render, create a scene file (see the samples/ directory for examples) and run Muon:

$ ./bazel-bin/muon/muon --scene path/to/scene.muon

To build the compilation database, install bazel-compilation-database and run:

$ bazel-compdb -s

To run the linter, first build the compilation database and then run:

$ clang-tidy muon/*.cc

To run the image diff tests, install ImageMagick and then run:

$ bazel test //test:all

Attribution

Muon was built based on the wonderful course material by Ravi Ramamoorthi, both Computer Graphics I on EdX and Computer Graphics II: Rendering, as well as the amazing PBR book and the Ray Tracing in One Weekend series by Peter Shirley.

In addition, Muon would not be possible if not for the following open source tools and libraries:

  • GLM
  • CImg
  • abseil
  • assimp
