p5: implement more of p5js API #6

Open sbinet opened 3 years ago

sbinet commented 3 years ago

we should implement more of the p5js API:

https://p5js.org/reference/
[x] path
[x] rotate
[x] scale
[x] transform
[x] push/pop
[x] bézier
[x] curve
[ ] frame-rate
[ ] resize-canvas
[ ] vector (just use gonum.org/v1/gonum/spatial/r2.Vec)
[x] image loading, image display
[ ] keyboard callbacks

math

[ ] noise (https://p5js.org/reference/#/p5/noise)
[ ] noiseDetail (https://p5js.org/reference/#/p5/noiseDetail)
[ ] noiseSeed (https://p5js.org/reference/#/p5/noiseSeed)

What about loading and rendering images, is it planned?

sbinet commented 3 years ago

it wasn't. it's just been added to the TODO list :)

koxu1996 commented 3 years ago

Keyboard events e.g. keyPressed() are missing as well. I was thinking about adding such functionality here: https://github.com/go-p5/p5/blob/cbaf5d8b21ca3ae9f2d75af07728070a0939bf31/proc.go#L240 however you are the master of Golang and Gio, so I hope you could implement it :grin:

sbinet commented 3 years ago

a first stab is over there:

https://github.com/go-p5/p5/pull/52

but I am not completely satisfied with the API (nor with some limitations + performances. see: gio-list)

koxu1996 commented 3 years ago

@sbinet Nice! I would like to prepare better PR, just give me few days.

PR attempt: https://github.com/go-p5/p5/pull/53.

Are you planning on implementing the noise(), noiseDetail() and noiseSeed()?

sbinet commented 1 year ago

I've added those to the bucket list.

Perlin noise isn't super complicated and there are a couple of Go packages to implement it:

https://github.com/aquilax/go-perlin
https://github.com/ojrac/opensimplex-go (we could just import one of them and reuse)

@LCRERGO, do you want to give it a try ?

Sure, I'll take a look at it

for mouse and keyboard callback, isn't is possible to simply pass the gio events to the user callbacks? (instead of maintaining a global variable for current state of the mouse) keyPressed(key.Event) mouseChanged(pointer.Event)
