Rotating a specific part of a model in THREE.js

Whether it's feasible to adjust the position or rotation of a component within an OBJ (or similar format) model. Can one manipulate a single model instead of needing multiple ones? What is the optimal approach to achieve this goal effectively? Appreciate any insights.

Answer №1

When a model is made up of just one geometry, it's impossible to rotate a specific part of the model without manually altering the geometry itself.

However, if the model is structured as a hierarchy of Object3Ds and/or Meshes (as demonstrated in examples like ), you have the ability to rotate any branch or leaf by using:

object.rotation.set( x, y, z );

This method works effectively in three.js r.69
