In my three.js project, I've set up a room scene with various lights added to it.
Features such as exposure, power, and height adjustments have been included in the setup.
You can view the progress so far by visiting this link.
My next goal is to implement a feature to adjust the temperature of the light source.
How would I go about doing that?
Take a look at the following code snippet for an illustration:
var renderer = new THREE.WebGLRenderer;
var scene = new THREE.Scene;
var camera = new THREE.PerspectiveCamera;
var cube = new THREE.Mesh( new THREE.BoxGeometry, new THREE.MeshPhongMaterial );
var spot = new THREE.SpotLight;
var inputs = [ ...document.querySelectorAll( 'input' ) ];
var destinationColor = new THREE.Color( 1, 1, 1 );
var fps = 1000 / 16;
var width = innerWidth;
var height = innerHeight / 2;
renderer.setSize( width, height );
camera.aspect = innerWidth / height;
camera.updateProjectionMatrix();
camera.position.set( 0, 0, 10 );
camera.lookAt( scene.position );
spot.position.set( 0, 0, 50 );
spot.lookAt( scene.position );
scene.add( cube, spot );
function inputChanged( event ){
destinationColor.fromArray( inputs.map(input => input.value) );
}
function update(){
spot.color.lerp( destinationColor, fps / 1000 );
renderer.render( scene, camera );
}
document.body.appendChild( renderer.domElement );
inputs.forEach(input => input.addEventListener( 'change', inputChanged ));
setInterval( update, fps );<script src="https://cdnjs.cloudflare.com/ajax/libs/three.js/92/three.min.js"></script>
