I am looking to generate a unique cylinder with a slanted bottom shape using three.js. I have explored the documentation but did not come across any built-in features for creating this specific geometry. I attempted to cut the cylinder with a slanted plane, however, I was unable to find an operation for this in the available resources. If anyone has suggestions on how to achieve this unconventional shape, please advise.
You have the freedom to manipulate vertices at your discretion.
Here is a basic concept:
var scene = new THREE.Scene();
var camera = new THREE.PerspectiveCamera(60, window.innerWidth / window.innerHeight, 1, 1000);
camera.position.set(0, 0, 10);
var renderer = new THREE.WebGLRenderer({
antialias: true
});
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);
var controls = new THREE.OrbitControls(camera, renderer.domElement);
var light = new THREE.DirectionalLight(0xffffff, 0.5);
light.position.setScalar(10);
scene.add(light);
scene.add(new THREE.AmbientLight(0xffffff, 0.5));
var cylGeom = new THREE.CylinderBufferGeometry(1, 1, 5, 16);
var vertices = cylGeom.attributes.position;
// modify upper vertices
var v3 = new THREE.Vector3(); // temporary vector
for (let i = 0; i < vertices.count; i++) {
v3.fromBufferAttribute(vertices, i); // set the temporary vector
v3.y = v3.y > 0 ? (v3.x * 0.5) + 2.5 : v3.y; // adjust position based on condition and equation
vertices.setY(i, v3.y); // set Y-component of a vertex
}
var cylMat = new THREE.MeshLambertMaterial({
color: "aqua"
});
var cyl = new THREE.Mesh(cylGeom, cylMat);
scene.add(cyl);
renderer.setAnimationLoop(() => {
renderer.render(scene, camera)
});body {
overflow: hidden;
margin: 0;
