//@author Omar Shehata. 2015.
//We are loading the Three.js library from the cdn here: http://cdnjs.com/libraries/three.js/
///////////////////This is the basic scene setup
var scene = new THREE.Scene();
var width = window.innerWidth;
var height = window.innerHeight;
var camera = new THREE.PerspectiveCamera( 70, window.innerWidth / window.innerHeight, 1, 1000 );
var renderer = new THREE.WebGLRenderer();
renderer.setSize( window.innerWidth, window.innerHeight );
document.body.appendChild( renderer.domElement );
///////////////////This is where we create our off-screen render target
//Create a different scene to hold our buffer objects
var bufferScene = new THREE.Scene();
//Create the texture that will store our result
var bufferTexture = new THREE.WebGLRenderTarget( window.innerWidth, window.innerHeight, { minFilter: THREE.LinearFilter, magFilter: THREE.NearestFilter});
//Let's create a red box
var redMaterial = new THREE.MeshBasicMaterial({color:0xF06565});
var boxGeometry = new THREE.BoxGeometry( 5, 5, 5 );
var boxObject = new THREE.Mesh( boxGeometry, redMaterial );
boxObject.position.z = -10;
bufferScene.add(boxObject);//We add it to the bufferScene instead of the normal scene!
///And a blue plane behind it
var blueMaterial = new THREE.MeshBasicMaterial({color:0x7074FF})
var plane = new THREE.PlaneBufferGeometry( window.innerWidth, window.innerHeight );
var planeObject = new THREE.Mesh(plane,blueMaterial);
planeObject.position.z = -15;
bufferScene.add(planeObject);//We add it to the bufferScene instead of the normal scene!
////////////////////////////Now we use our bufferTexture as a material to render it onto our main scene
var boxMaterial = new THREE.MeshBasicMaterial({map:bufferTexture});
var boxGeometry2 = new THREE.BoxGeometry( 5, 5, 5 );
var mainBoxObject = new THREE.Mesh(boxGeometry2,boxMaterial);
mainBoxObject.position.z = -10;
scene.add(mainBoxObject);
//Render everything!
function render() { requestAnimationFrame( render ); //Make the box rotate on box axises boxObject.rotation.y += 0.01; boxObject.rotation.x += 0.01; //Rotate the main box too mainBoxObject.rotation.y += 0.01; mainBoxObject.rotation.x += 0.01; //Render onto our off screen texture renderer.render(bufferScene,camera,bufferTexture); //Finally, draw to the screen renderer.render( scene, camera );
}
render();
