Parameters: This method accepts three parameters as mentioned above and described below:
- x: It is a number that denotes the x position of the point in world space.
- y: It is a number that denotes the y position of the point in world space.
- z: It is a number that denotes the z position of the point in world space.
The example below illustrates the setPosition() method in p5.js:
Example:
Javascript
let currCamera; function setup() { createCanvas(500, 500, WEBGL); helpText = createP( "Move the sliders to change the " + "position of the camera" ); helpText.position(20, 0); // Create the camera currCamera = createCamera(); // Create three sliders for changing the // position of the camera xPosSlider = createSlider(-360, 360, 0); xPosSlider.position(20, 40); yPosSlider = createSlider(-360, 360, 0); yPosSlider.position(20, 70); zPosSlider = createSlider(0, 800, 600); zPosSlider.position(20, 100); } function draw() { clear(); lights(); normalMaterial(); debugMode(); // Get the x, y, z values from the // sliders let currX = xPosSlider.value(); let currY = yPosSlider.value(); let currZ = zPosSlider.value(); // Set the position of the camera // to these points in the world space currCamera.setPosition(currX, currY, currZ); cylinder(90); } |
