How to Distort an Array of Images in Processing

Are you looking to create a visually stunning effect by distorting an array of images in Processing? You’ve come to the right place! In this guide, we will dive into how to merge two pieces of code: one that displays a grid of images and another that applies a distortion effect inspired by waves. Let's tackle your question step-by-step!

The Problem

You have successfully created a grid of images that load randomly when you click the mouse. Each image displays perfectly when you work with a single instance. However, your goal is to extend this effect to an array of images, applying the same distortion effect you’ve used successfully with a single image. Let’s explore how we can combine these codes!

Understanding the Code Structure

Grid Code

This section loads a grid of images and displays them. Here’s a simplified breakdown:

Image Loading: The loadImages() function loads images into an array.

Setup: The setup() function initializes the canvas size and image properties.

Mouse Interaction: The mousePressed() function reloads images when the mouse is clicked.

Display Loop: The draw() function loops through the image array and draws them on the canvas.

Wave Code

This code distorts a single image based on mouse movement:

Image Initialization: myImage is loaded in the setup() function.

Distortion Effect: The draw() function applies a distortion effect using sinusoidal calculations.

Now, let’s see how we can merge these two approaches!

Merging the Codes

Step 1: Global Variables

First, you'll want to ensure that the speed variables for distortion are accessible globally. Declare these at the top:

Step 2: Update Load Images Function

Keep your existing loadImages() function intact, ensuring it populates the image array as before.

Step 3: Modify the Draw Function

The key step is to modify your draw() function in the grid code to apply the distortion effect across all images in the grid:

Keep the Existing Code: Maintain the current loop that displays the images.

Add Distortion Calculation: At the end of the draw() function, incorporate a loop that applies the distortion:

Final Touches

Make sure to run your code after these modifications. With the distortion applied properly across the whole canvas, you should see an exciting array of images that shift and wobble as you move your mouse!

Conclusion

By following these steps and merging the power of grids and distortion in Processing, you can create interactive and dynamic visual experiences. Feel free to modify the speed and distortion parameters to fit your artistic vision. Happy coding!
