How to Fill A Shape With A Gradient on P5.js?

8 minutes read

To fill a shape with a gradient on p5.js, you can use the createRadialGradient or createLinearGradient functions to define the gradient you want to apply. These functions create a gradient object that you can then use as a fill for your shape. After creating the gradient object, you can set it as the fill for the shape using the fill() function before you draw the shape. By specifying the start and end points for the gradient, as well as the colors and stops along the gradient, you can create custom gradients to fill your shapes with on p5.js.

What is a gradient transition in p5.js?

A gradient transition in p5.js refers to the gradual change of color or opacity in a shape or background. This effect creates a smooth transition between two or more colors, adding depth and visual interest to the design. Gradient transitions can be linear, radial, or angular, and can be customized by specifying the colors, direction, and shape of the gradient. This feature is commonly used in creative coding and web development to enhance the visual appeal of graphics and animations.


What is a gradient interpolation in p5.js?

In p5.js, gradient interpolation refers to the process of smoothly transitioning between different colors in a gradient. This can be achieved by creating a series of colors that gradually blend into each other, resulting in a smooth and continuous transition from one color to another. Gradient interpolation can be used to create visually appealing effects in graphics and animations. In p5.js, you can use functions such as lerpColor() to interpolate colors and create gradients.


How to fill a shape with a horizontal gradient on p5.js?

To fill a shape with a horizontal gradient on p5.js, you can use the createCanvas() and createGraphics() functions to create a separate graphics buffer for the gradient, and then use the p5.Image object to draw the gradient onto the shape.


Here's an example code snippet demonstrating how to fill a rectangle with a horizontal gradient in p5.js:

let gradient;

function setup() {
  createCanvas(400, 400);
  
  gradient = createGraphics(width, height);
  gradient.background(255);
  for (let x = 0; x < gradient.width; x++) {
    let inter = map(x, 0, gradient.width, 0, 1);
    let c = lerpColor(color(255, 0, 0), color(0, 0, 255), inter);
    gradient.stroke(c);
    gradient.line(x, 0, x, gradient.height);
  }
}

function draw() {
  background(220);

  // Draw rectangle filled with gradient
  image(gradient, 0, 0);
  fill(gradient);
  rect(100, 100, 200, 200);
}


In this code snippet, we first create a graphics buffer called gradient to store the horizontal gradient. Inside the setup() function, we generate the gradient by looping through each pixel in the buffer and setting its color based on its position. Then, in the draw() function, we draw the gradient onto the canvas using the image() function and fill a rectangle with the gradient using the fill() function.


You can customize the colors of the gradient and the shape, as well as the width and height of the shape to create different effects.


What is a linear gradient fill in p5.js?

A linear gradient fill in p5.js is a type of fill that creates a gradual transition between two or more colors, forming a linear gradient. This allows you to create smooth color transitions in shapes and paths, adding visual interest and depth to your designs.
