Particle System "Options" in Open Processing

in General Discussion • Other • 1 year ago

Good Day,

I am a fairly new art student in the [open] processing [art] world. The program was introduced to me in a Digital Imaging course I signed up for this Spring as I'm preparing to finish a Masters program (non-MFA).

Digressing, I am working on my very first audio visualization (which I'm finding to be a taboo thing to say about Audio-Input based image coding).

To be brief, what I AM NOT looking for is this:

Someone to write code for me
Someone to tell me, "oh this is simple..." in a patronizing manner
Someone to assume I know things already regarding the code in the current, non-beta version of processing.

What I AM looking for is this:

References to books (specifically chapters and pages)
exemplars and examples via video websites and image archive websites
An explanation on layman's terms that would require I "Google" or reference elsewhere for further background information

I am an educator, and personally have found the most popular books & literature on processing to be Computer Science focused, and not focused on teaching to _all_ types of learners or methods of learning, for people of varying content area/subject matter backgrounds and upbringing. This program is powerful, and better yet FREE! But still has a lot of potential in education for the masses.

Digressing from that, I basically would like to do the following:

Create an audio input based visualization that has small particle arrays floating amorphously (at random) and interacting in a not so violent way based n the audio or music input to the code in its library.
Additionally, the particles move on all 3D axis (x,y,z) and stay within the boundary of the canvas size.
Lastly they may change colors occasionally, but not always and the number of particles that do change are limit to upto 50% and not all 360+ particles.
If possible, there is a 3D environment as well that looks like a stage or stageroom.

Thank You For Reading & For Your Time.

Well, as I see it, there are two parts to what you're trying to get done.

The first part is a visualization of some audio. These can vary in complexity, but they are all based, eventually, on the waveform the sound makes. I would suggest that you look at the examples that come with Processing, specifically "File > Examples > Libraries > Minim > loadFile". This simple example of a audio visualization just draws the waveforms with lines, but it does show you how you can get values from audio to use in the other part.

The other part, of course, is a 3D scene filled with particles. You'll probably want to define a Particle class, which would keep track of everything a Particl needs to know - its position, size, velocity, color, shape, etc. - as well as having functions to move the Particles (possibly based on where the other Particles are, or the values from the audio file). You should look at "File > Examples > Topics > Simulate > SimpleParticleSystems" to get started.

Don't forget that you can look thinks up in the reference too: http://processing.org/reference/alpha.html

Good Afternoon,

I attempted to do the following at my university's MAC lab but to no avail, I couldn't locate the folder after unpacking the processing program. Any direct URL links for the same applet?

tfguy44,

THANK YOU very much for your response.

What I plan to do is carefully follow the information provided, apply it after viewing the exemplars, and share my finidngs on this post as to help anyone else (present or future) who may encounter a similar issue I have.

Regarding the 3D stage/stageroom - if I have time prior to graduating this semester, i will attemempt to implement that. In the least, I'll have it as a side sketch for potential credit in my course.

If anyone else would like to add some pointers or place suggestions, they are very much welcome and open to do so... it won't be disregarded.
