I'm kinda new to Three.js, I'm enjoying it a whole bunch, though I'm having an issue with shadow maps, I've read and looked everywhere but I just can't get it to work, can somebody point me in the direction of what I'm doing wrong?
var scene = new THREE.Scene();
var camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 0.1, 1000 );
var renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);
var geometry = new THREE.BoxGeometry(1,1,1);
var cube = new THREE.Mesh(geometry, new THREE.MeshLambertMaterial( {color: 0x808080 } ));
cube.castShadow = true;
scene.add( cube );
camera.position.y = 2;
var directionalLight = new THREE.DirectionalLight( 0xffffff, 0.5 );
directionalLight.position.set( 0, 10, 0 );
directionalLight.castShadow = true;
scene.add( directionalLight );
var geo2 = new THREE.BoxGeometry(5,0.1,5);
var floor = new THREE.Mesh(geo2, new THREE.MeshLambertMaterial( {color: 0x808080 } ));
floor.position.y = -1;
floor.receiveShadow = true;
scene.add(floor);
renderer.shadowMapEnabled = true;
renderer.shadowMapType = THREE.PCFSoftShadowMap;
var ambient = new THREE.AmbientLight( 0x111111 );
directionalLight.shadowCameraVisible = true;
scene.add( ambient );
renderer.shadowCameraNear = 3;
renderer.shadowCameraFar = camera.far;
renderer.shadowCameraFov = 50;
function animate() {
camera.lookAt({x:0,y:0,z:0});
var timer = Date.now() * 0.0002;
camera.position.x = Math.cos(timer) * 5;
camera.position.z = Math.sin(timer) * 5;
requestAnimationFrame(animate);
render();
}
function render() {
cube.rotation.x += 0.1;
cube.rotation.y += 0.1;
renderer.render(scene, camera);
}
animate();
These three lines:
renderer.shadowCameraNear = 3;
renderer.shadowCameraFar = camera.far;
renderer.shadowCameraFov = 50;
should be on your light not the renderer; so
directionalLight.shadowCameraNear = 3;
directionalLight.shadowCameraFar = camera.far;
directionalLight.shadowCameraFov = 50;
and since your light is directional you will need:
directionalLight.shadowCameraLeft = -500;
directionalLight.shadowCameraRight = 500;
directionalLight.shadowCameraTop = 500;
directionalLight.shadowCameraBottom = -500;
and you might need to play around with these values.
