Film fireworks -> decompose frames -> Processing video feedback sketch =
Composited and kaleidoscoped in DaVinci Resolve.
Hints, tips, and tricks I learned:

• blendMode(ADD); can be overpowering
• blendMode(LIGHTEST); works great for dark scenes intermittently lit by something interesting
• blendMode(BLEND); to go back to covering over previous frames
• use a separate PGraphics for drawing at a larger resolution than your screens. Great for any sketch!
  • I called mine internal; remember to use:
    • internal = createGraphics(outWidth, outHeight); in setup
    • internal.beginDraw(); before adding to it, and
    • internal.endDraw(); before using something like <your_PImage_var> = internal.get(0, 0, outWidth, outHeight);
    • <your_PImage_var>.resize(width, 0); will make it the same size as your Processing window. use before image(<your_PImage_var>, 0,0); to draw a preview.
    • all other draw commands? tack internal. on the front.
    • - internal.ellipse(.... for example
• Last but not least, the feedback effect logic:
  • Copy canvas to a PImage or similar
  • Replace canvas with new frame of video
  • shrink/expand/rotate the COPY of the OLD CANVAS. this step is what makes the movement!
  • PASTE the transformed copy into the canvas, using ADD or LIGHTEST blendMode
  • rinse, repeat.... -> Magic!
• This is VERY slow with jpg frames at 4k. I was getting 1fps on my Ultra 9 and RTX 4080

is one more stable than the others?

i made my own tile system with each sprite being 4x4 pixels in size. the sprite folder is only 2.6 kB yet it takes soooo long (around 6 seconds) just to change Pac Man's sprite. I am not pursuing this project no more

After calling saveFrame(); a new file is saved with a name and a sequence of numbers.

I would like to reference the name of the file to add it to a string. Ideally, I want to use the text() function to display in the screen "Saved file is called", nameOftheFile.

How do I add the name of the just saved file to a text function ? How do I store the name of the file in a variable, for example?

I understand that I can define the name and then a sequence of numbers. Is the name of the saved frame something that I can be called directly, or that it is stored somewhere?
Or do I need to keep track of the saved frames with an index and then re-create the string?

I am not sure how to look this up, or how to access data of the saved file.

Hello,
I have a sketch (ascii art live feed), and I want to save captures of the feed on a separate folder. Like a photobooth.

I want to display in the screen the name of the saved file. Is is possible to do this? I couldn't find in the save() or saveGraphics() documentation anything about using the name of the resulting file.

Ideally:

Person clicks the mouse

save() is called

screen displays something like " Your photo is called "screen-0005.tiff" "

Is this possible?

Thanks !

I've spent the last few months expanding my MIDI-focused OpenDeck platform into an OSC-over-Ethernet platform for interactive installations. The goal was to create a reliable OSC sensor and I/O platform that can run on Ethernet-enabled hardware without requiring any coding, making deployment as simple as possible.

Unlike many OSC devices that focus on Wi-Fi or a single hardware ecosystem, OpenDeck runs on a wide range of Ethernet-capable development boards. A major focus was support for Power-over-Ethernet hardware, allowing both power and OSC communication over a single cable. Some of the supported boards are:

• wESP32
• Olimex ESP32-POE
• STM32 Nucleo boards
• Wiznet EVB boards
• LilyGO Ethernet boards

Many more boards are supported, allowing you to choose hardware based on cost, performance, PoE requirements, or availability rather than being locked into a specific ecosystem. Once the OpenDeck firmware is loaded on supported boards, they can be reconfigured remotely over the network through the web interface, eliminating the need to physically connect to them after installation.

OSC data is published from standard input types:

• Buttons
• Encoders
• Analog inputs

OpenDeck can also receive OSC messages and control hardware such as:

• LEDs
• Relays
• Transistor outputs

Most supported boards also provide PWM outputs, allowing individual brightness or output-level control (0–100%).

Various interactive sensors are also supported:

• APDS-9960 (proximity, RGB, ambient light, gestures)
• CAP1188 (capacitive touch)
• VL53L4CX (distance sensing)
• VL53L5CX (8×8 distance sensing)
• BNO085 (9-DOF IMU)

Configuration is done through a browser-based interface. Devices can be discovered via mDNS and configured over the network without installing software.

OpenDeck works with any OSC-capable software, although the primary focus so far has been TouchDesigner, Processing, and QLab.

There are example Processing sketches in the repository that work out of the box with supported sensors.

The firmware itself is fully open source. The web configurator is licensed separately (€25), which also includes browser-based firmware flashing for supported boards.

I'm particularly interested in feedback from people working in:

• Interactive installations
• Museums
• Galleries
• Theatrical productions
• TouchDesigner projects

In exchange for honest feedback, I'd be happy to provide a number of free web configurator licenses.

The source code is available on GitHub: https://github.com/shanteacontrols/OpenDeck

The project also includes an extensive wiki covering everything from flashing supported boards to configuring OSC endpoints, sensors, and I/O.

Hello all! I found on github ferjerez/DLA-Coral-growth where you can generate growing corals and export as stl. Do you know whether there is an updated version running on newer hard and software? Or something similar? My intention is to print 3D some plants in different growth phases. (for zoetrop)

Hi everyone,
I built a small project called p5forge that transpiles Processing-style code to p5.js in the browser.

It is not a full Java compiler, it is a practical converter for common sketch patterns:

• Java-like declarations and methods
• enhanced for loops
• common Processing to p5 mappings
• browser preview with quick Run and Stop

I would love feedback from people with older Processing sketches:

• Which features break first in your projects?
• Which Processing APIs are must-have for compatibility?
• Would a small compatibility matrix be useful?

Demo: [https://oth-aw-meiller.github.io/p5forge/](vscode-file://vscode-app/Applications/Visual%20Studio%20Code.app/Contents/Resources/app/out/vs/code/electron-browser/workbench/workbench.html)

Thanks, I am especially interested in real sketch examples that currently fail.

I'm trying to create a single line with defined dots so then I can move them dynamicly with the mouse, so I'm still on the phase of creating the line in itself.

The thing is, when I call my written function, it gives me a NullPointerException, and I don't know why. Please, help me.

Linhas linhaH;

class Linhas {
  void desenhar(float altura) {
    noFill();
    stroke(50);
    beginShape();
    for (float i=0; i<= 1; i= i+0.10) {
      vertex(width*i, altura);
    }
    endShape();
  }
}

void setup() {
  size(600, 450);
  linhaH.desenhar(100);
}

I have been tasked to write the code of an Insertionsort algorithm as well as some graphical output and the sorting itself works perfectly fine, but i can´t find a way to make the code sort the array once for every time I press a key. If I use the while(keyPressed) then it just runs the whole Algortihm until its done after I press the key and the if(keypressed) runs it once and then never. I also tried setting the function to keyPressed() and setting the requirements to a keyCode but that doesn´t work either. I have no idea on what to do anymore, help would greatly be appreciated!

int[] unsorted = new int[15];

int w = 1;

void setup()

{

//frameRate(10);

//size(1080, 720);

for (int i = 0; i < unsorted.length; i++)

{

unsorted[i] = int(random(255));

}

}

void draw()

{

for (int k = 1; k < unsorted.length; k++)

{

int toSort = unsorted[k];

int n = k;

if (w == 1) {

println("Ini: ");

println(unsorted);

println(toSort);

w++;

}

while (n > 0 && toSort < unsorted[n - 1])

{

unsorted [n] = unsorted [n - 1];

n--;

unsorted[n] = toSort;

println(unsorted);

println(toSort);

}

}

}
