As a newcomer to the world of 3D Graphics programming, I have started using Three.js to develop a software application that involves 3D bin packaging visualization. Currently, my code is focused on creating and positioning two elements.
var camera, scene, renderer;
var mesh, mesh2;
init();
function init() {
camera = new THREE.PerspectiveCamera( 70, window.innerWidth / window.innerHeight, 1, 1000 );
camera.position.z = 800;
scene = new THREE.Scene();
var texture = new THREE.TextureLoader().load( 'https://threejs.org/examples/textures/crate.gif' );
var geometry = new THREE.BoxBufferGeometry( 200, 200, 200 );
var geometry2 = new THREE.BoxBufferGeometry( 200, 200, 200 );
var material = new THREE.MeshBasicMaterial( {map:texture} );
mesh = new THREE.Mesh( geometry, material );
mesh2 = new THREE.Mesh( geometry2, material );
mesh2.position.x = 170
mesh2.position.y = -48
mesh2.position.z = 100
mesh.rotation.x = 0.45;
mesh.rotation.y = 1;
mesh2.rotation.x = 0.45;
mesh2.rotation.y = 1;
scene.add( mesh2 );
scene.add( mesh );
renderer = new THREE.WebGLRenderer( { antialias: true } );
renderer.setPixelRatio( window.devicePixelRatio );
renderer.setSize( window.innerWidth, window.innerHeight );
document.body.appendChild( renderer.domElement );
}
Currently, I have manually set the coordinates (170, -48, 100) to position the second cube. However, I believe there should be a more systematic approach to calculate these x, y, z values, especially when dealing with rotations (x=0.45, y=1). I am uncertain about the starting point for these calculations.
The challenge at hand involves determining a method to calculate and position cubes based on their dimensions (l1, w1, h1), (h2, w2, h2), and so on, along with their respective positions (x1, y1, z1), (x2, y2, z2), and beyond. How can these cubes be efficiently aligned and arranged, either near each other or stacked?
