My first sketch
Dec 30^th, 2008, 5:58pm

Hello world!

Here it is after 3 month I got the blue book and reading every day the famous processing blog sites and using this forum I manage to get my hello world sketch, check it out here:

http://homepage.ntlworld.com/ricardo.sanchez/processing/applet/

Hope you like it! and if you have any comments on the code PLEASE post it here, as the next step on this is making the orbs behave in 3 stages birth, survive and death.

I am very new to this language, they way it renders and how you have to build the stuff. Must keep the practice going.

One thing I want to say is this HELP me A LOT on my Actionscript code, specially the OOP side of programing, so for that thanks to Casey and Ben.

kiza YaBB Newbies Offline Posts: 24	Re: My first sketch Reply #3 - Jan 2^nd, 2009, 6:26pm Very nice, simple but pretty. Just a suggestion, even thought it's better to give every orb an image reference in case you want to let each have a different one latter on, it's faster to take the img and make it a global variable, only having to load it once. Calling loadImage 500 is a bit costly

Hey, thanks for the comments very cool!

Blahblab, the opengl stuff i got it from this post:

http://processing.org/discourse/yabb_beta/YaBB.cgi?board=OpenGL;action=display;num=1226360818;start=4#4

as far as I can tell the code I use is only for the GLOW effect, and I think it also helps on the speed, but I just copy and paste so I cant tell any more on the subject. One thing is first I use color mode RGB then change it to HSB and got much better results, maybe is the same thing...

Kiza, thanks to point that out I will fix it on the weekend! and post here the new link, maybe I will try to draw the orb in processing, but not sure how I can get the blur inside the out border halo.

Also do you know if is possible to use the noise(x, y) to update the possition of the objects, or the way I did it is the best approach?

ej:
x = noise(n1);
y = noise(n2);

Cheers!

Hi Kiza, it just renders the hole thing much faster! and it was easy to change, got to love OOP!

But I change it a bit instead of bringing all the orbs instanty, now they appear every 300 milliseconds, check the update on this post, where I got help with the millisecond interval stuff:

kiza YaBB Newbies Offline Posts: 24	Re: My first sketch Reply #7 - Jan 3^rd, 2009, 8:09pm Glad to hear it's faster. I do prefer the style of the previous one thought..

Both versions are very pretty to behold. You have inspired me

Also, i didn't recognize the lerp function and looked in up in the reference. Glad to have learned a new math function-- so simple, and useful-- this simple interpolation function saves a few lines of code and keeps things clean.

Funny, Perl has been my most-used language over the years.. not sure if there was a lerp in perl tho. get it?

"l-e-r-p" in
"P-e-r-l"

hahaha. ahem.

Cheers rS

garyduke YaBB Newbies Offline Posts: 7	Re: My first sketch Reply #10 - Jan 7^th, 2009, 6:03pm Now _that_ is funny. One person's bug is another person's feature I was wondering how you got the orbs to swarm around the middle and thought that was a nice touch and intentional haha

Jack Perkins Junior Member Offline Posts: 99	Re: My first sketch Reply #11 - Jan 9^th, 2009, 2:22am I was about to say the clustering of them in the middle is really nice looking, the glow is complex from all the independent motions.

RicardoSanchez YaBB Newbies Offline Posts: 5	Re: My first sketch Reply #13 - Jan 15^th, 2009, 8:03pm Any chance of getting the glowing orb .png? I would like to run this on my machine to play with and learn from. Cool stuff btw, -ricardo

@ Ricardo, I just send you a private message with the location, let me know if you get them.

Also you can use any .png you want

One thing to mention on that code is that this:

float nx = lerp(0, width, noise(xnoise));
float ny = lerp(0, height, noise(ynoise));

can be replace with this:

float nx = noise(xnoise) * width;
float ny = noise(ynoise) * height;

If that makes sence

Cheers
