Discover the precise element that was clicked in three js using the raycaster and intersects when intricate components are closely integrated to shape a complex model

My current project involves working on a 3D model in three.js that consists of multiple small parts joined together to create a loader. I am utilizing raycaster and intersects to determine which element has been clicked. The model resembles a door, complete with screws, handles, hinges, bolts, rails, rotation points, pivots, and more.

The issue I am facing is that the elements are not being recognized by raycaster and three.js unless I zoom in significantly. Only when I zoom in can I accurately identify the clicked element. Is there a solution to this problem that would allow me to avoid having to zoom in to detect elements?

Answer №1

To enhance the accuracy of intercepting small elements such as screws, it could be beneficial to incorporate an extra mesh that is specifically attached to these objects. This additional mesh can take the form of a large sphere geometry shape surrounding the screw. Despite being invisible in appearance (due to its false material visibility), this larger sphere geometry serves the purpose of effectively facilitating raycasting towards the challenging-to-intercept components like screws.
