The model() function is used to render a 3D model to the screen. The model to be rendered has to be loaded first using the loadModel() function.
Syntax:
model( model )
Parameters: This function accepts one parameter as mentioned above and described below.
- model: It is the p5.Geometry object that specifies the model that has to be rendered to the screen.
The program below illustrate the model() function in p5.js:
Example:
let ballObj, cubeObj, coneObj; let currentObj; let newFont; // Load all the models in preload() function preload() { newFont = loadFont("fonts/Montserrat.otf"); ballObj = loadModel("models/ball.obj", true); cubeObj = loadModel("models/cube.obj", true); coneObj = loadModel("models/cone.obj", true); currentObj = ballObj; } function setup() { createCanvas(400, 300, WEBGL); textFont(newFont, 14); modelSelector = createSelect(); modelSelector.position(30, 40); modelSelector.option("ball"); modelSelector.option("cube"); modelSelector.option("cone"); modelSelector.changed(modelChanged); } // Function to change the model depending // on the selected dropdown function modelChanged() { let selected = modelSelector.value(); console.log(selected); switch (selected) { case "ball": currentObj = ballObj; break; case "cube": currentObj = cubeObj; break; case "cone": currentObj = coneObj; break; default: break; } } function draw() { background("green"); text("Use the dropdown to select the model to display", -185, -125); scale(0.75); lights(); rotateX(frameCount * 0.05); rotateY(frameCount * 0.05); noStroke(); // Load the given model model(currentObj); } |
