Breaking apart a mesh using THREE.js

Can a single THREE.Mesh be divided into multiple meshes?

For instance, can a mesh with 2,000,000 polygons be split into 2,000 meshes each with 1,000 polygons?

Edit: Realistically, it may not be possible to retain the exact same number of polygons/vertices after splitting the original mesh, but an approximation would also be beneficial.

Answer №1

Imagine the excitement of watching a sphere burst into 1000 miniature spheres! How about creating a JavaScript function that can extract a mesh from the scene, retrieve its polygons, divide them, and then generate new meshes based on mathematical equations? Don't forget to remove the original mesh using "scene.remove(object);" before adding the new meshes at random x, y, z coordinates in place of the old mesh.
