clojerl / doodler

Create drawings with code (heavily inspired in Clojure's Quil)

doodler

A Clojerl application to create drawings.

Build

$ rebar3 compile

Examples

There are some example sketches that you can run.

For example to start the circles example use the following code:

$ rebar3 clojerl repl
Clojure 0.9.0
clje.user=> (require '[doodler.examples.circles :as c])
nil
;; Start the sketch with a regular 2D canvas
clje.user=> (c/sketch)
#erl[:wx_ref 35 :wxFrame #<0.615.0>]

There's also (currently limited) for OpenGL which can be enabled by providing :open-gl true to the skecth:

;; Start the sketch with an OpenGL canvas
clje.user=> (c/sketch :renderer :opengl)
