Below you can find comparison Processing functions with Clojure2d.
Assuming that following variables are defined:
window- display created with [[show-window]]cnvs- canvas created with [[canvas]] inside drawing context (see [[with-canvas->]] or [[with-canvas]])
And following namespaces are loaded:
(:require [clojure2d.core :refer :all] ;; generaral Clojure2d functions
[clojure2d.pixels :as p] ;; pixels operations
[clojure2d.color :as c] ;; color operations
[fastmath.core :as m] ;; general math functions
[fastmath.random :as r]) ;; random and noise| Processing | Clojure2d | Comments |
|---|---|---|
| draw() | Any function with following signature (fn [canvas window frame local-state] ...) attached to window created with [[show-window]] (:draw-fn key). |
Such function is called before refresh of the display. Result is passed as local-state in the next call. |
| exit() | [[close-window]] | Closes window programmatically. |
| loop() | not implemented | possible in future versions |
| noLoop() | not implemented | possible in future versions |
| popStyle() | not implemented | |
| pushStyle() | not implemented | |
| redraw() | not implemented | not necessary |
| setup() | Any function with following signature (fn [canvas window] ...) attached to window created with [[show-window]] (:setup key). |
Returned value is treated as local-state for first call of drawing function. |
| thread() | use future |
|
| all the rest | use Clojure |
| Processing | Clojure2d | Comments |
|---|---|---|
| cursor() | not implemented | possible in future versions |
| delay() | not implemented | use Thread/sleep |
| displayDensity() | not implemented | |
| focused | not implemented | possible in future versions |
| frameCount | implemented | frame number is passed to the drawing function as third parameter |
| frameRate() | implemented | set :fps key when [[show-window]] is called |
| frameRate | not implemented | |
| fullScreen() | not implemented | possible in future versions |
| height | [[height]] | it's a function working on canvas/window/image |
| noCursor() | not implemented | possible in future versions |
| noSmooth() | implemented | use :low quality key in [[canvas]] call |
| pixelDensity() | not implemented | for Retina use two times bigger canvas/window and call (scale canvas 2). |
| pixelHeight | not implemented | |
| pixelWidth | not implemented | |
| settings() | not necessary | |
| size() | implemented | set size in [[canvas]] or [[show-window]] calls |
| smooth() | implemented | use one of the keys defined in [[rendering-hints]] and pass to [[canvas]] or [[show-window]] |
| width | [[width]] | it's a function working on canvas/window/image |
