What methods can be employed to prevent the camera from intersecting with GLTF objects loaded into our ThreeJS scene?

Greetings! I am currently experimenting with Threejs and aiming to create an online virtual tour. To achieve this, I have imported 3D objects as booths and set up a camera with PointerlockControl. While everything is functioning properly, the main concern is that the camera passes through the objects. This does not seem ideal. Is there a solution to prevent this issue?

Answer №1

Is the issue that the camera is occasionally positioned inside an object, allowing you to see the interior of the object from within (which is not visually appealing)? If this is the case, there are two main solutions:

  1. You could implement an objects collision system to detect when the camera intersects with an object.
  2. A simpler alternative would be to adjust your objects' material settings using Material.side = THREE.FrontSide. This will allow the camera to penetrate the object while ensuring that its interior remains hidden from view (if that is the specific concern).
