This website is currently loading a Maya model using the three.js library. The model includes various texture pictures.
Below is the JavaScript code:
var SCREEN_WIDTH = window.innerWidth;
var SCREEN_HEIGHT = window.innerHeight;
var container;
var camera, scene;
var canvasRenderer, webglRenderer;
var mesh, zmesh, geometry, materials;
var windowHalfX = window.innerWidth / 2;
var windowHalfY = window.innerHeight / 2;
var meshes = [];
function init() {
container = document.createElement('div');
document.body.appendChild(container);
camera = new THREE.PerspectiveCamera(75, SCREEN_WIDTH / SCREEN_HEIGHT, 1, 100000);
camera.position.x = 400;
camera.position.y = 200;
camera.position.z = 400;
scene = new THREE.Scene();
// LIGHTS
var ambient = new THREE.AmbientLight(0x666666);
scene.add(ambient);
var directionalLight = new THREE.DirectionalLight(0xffeedd);
directionalLight.position.set(0, 70, 100).normalize();
scene.add(directionalLight);
// RENDERER
webglRenderer = new THREE.WebGLRenderer();
webglRenderer.setSize(SCREEN_WIDTH, SCREEN_HEIGHT);
webglRenderer.domElement.style.position = "relative";
container.appendChild(webglRenderer.domElement);
var loader = new THREE.JSONLoader(),
callbackKey = function (geometry, materials) {
createScene(geometry, materials, 0, 0, 0, 6)
};
loader.load("chameleon.js", callbackKey);
window.addEventListener('resize', onWindowResize, false);
}
function createScene(geometry, materials, x, y, z, scale) {
zmesh = new THREE.Mesh(geometry, new THREE.MeshFaceMaterial(materials));
zmesh.position.set(x, y, z);
zmesh.scale.set(scale, scale, scale);
meshes.push(zmesh);
scene.add(zmesh);
}
function onWindowResize() {
windowHalfX = window.innerWidth / 2;
windowHalfY = window.innerHeight / 2;
camera.aspect = window.innerWidth / window.innerHeight;
camera.updateProjectionMatrix();
webglRenderer.setSize(window.innerWidth, window.innerHeight);
}
function animate() {
for (var i = 0; i < meshes.length; i++) {
meshes[i].rotation.y += .01;
}
requestAnimationFrame(animate);
render();
}
function render() {
camera.lookAt(scene.position);
webglRenderer.render(scene, camera);
}
$(document).ready(function () {
init();
animate();
});
Now I would like to change the first texture picture to a different one while keeping the rest of the textures the same at runtime. How can I achieve this?
