Newtonian

Particle System in Clojure using Quil.

Still work in progress.

Based on https://github.com/jsoverson/JavaScript-Particle-System

Usage

lein deps
lein run

or,

For interactive mode:

lein deps
lein repl (or if in Emacs, nrepl-jack-in, or clojure-jack-in)


(use 'newtonian.particle-system)
(require 'newtonian.utils)
(import 'newtonian.utils.Vector2D)

    ;; Start 

(-main)

;; Things to play with

;; To add repelling field, use negative mass

(add-field (Vector2D. 280.0 285.0) -100.0)

;; for attracting field, use positive mass

(add-field (Vector2D. 280.0 285.0) 500.0)

;; To remove last field added
(swap! fields pop)

;; To add particle emitter
(add-emitter (Vector2D. 330.0 280.0) (Vector2D. 1.5 1.0))

;; To remove last particle emitter added
(swap! emitters pop)

TODO

• Drag-and-drop support for Paritcle Emitters and Fields
• Dynamic sizing and coloring of particles with GUI
• Dynamic force field adjustment with GUI.
• Improve documentation
• Settings to change frame rate, window size, renderer, etc
• Preferences to change background color, number of particles, color of fields and emitters.
• Collapse particle system state in a map, to allow multiple particles systems. ???
• Aggregate force of all fields in particles, right now one field influence at a time
