Get more examples to try:-\n\n```bash\npropane --install samples\n```\nThe samples get copied to `~/propane_samples`, NB: depends on `wget`. for a simple demo of circumcircle math see `~/propane_samples/processing_app/library/vecmath/vec2d/circumcircle_sketch.rb` or to  run samples as a demo:-\n```bash\ncd ~/propane_samples\nrake\n# Some sketches require opengl which doesn't get installed on windows.\n# For other libraries see below\n```\nOr to run individual sketches `cd` to directory and:-\n```bash\ncd ~/propane_samples/processing_app/library/vecmath/vec2d\njruby circumcircle_sketch.rb\n```\nChanging directories is particulary important for sketches with extra files eg `data` or relative `*.rb` files.\n\nOr explore using `atom` editor and use `script` plugin to run (NB: make sure the file type is `Ruby` or `JRubyArt`, sketches wont run with type as `Ruby on Rails`) also make sure `jruby` is on your `path`.\n\n### Propane documentation\n\n[Propane web-site](https://ruby-processing.github.io/propane/)\n\n### Scope for improvement\n\nIn theory we should be able to use nmatrix (jruby version) in the matrix calculation, possibly on the gpu https://groups.google.com/forum/#!topic/sciruby-dev/CIC0EuTRNAk\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fruby-processing%2Fmath_demo","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fruby-processing%2Fmath_demo","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fruby-processing%2Fmath_demo/lists"}
