Lock finger position when grab/pinch objects

[ErosV]

Hello there,

I am using unity to develop a virtual reality application with Leap Motion and HTC vive. The goal is to pinch with thumb and index different objects. The "standard" implementation results in a interpenetration of thumb and index inside the objects to achieve grab/pinch. We would like to lock the position of thumb and index on the surface of the object when grasp/pinch it. Any ideas/suggestion to implement this feature?

Thanks in advance.
Eros.

Hi again,
Is there someone with any ideas or a point to start?
Thanks in advice,

Hi, are you trying to use the Interaction Engine to accomplish this?

Please note that this is an unreleased experimental feature but we have an articulated hands example available in our Unity Modules that should help with the locking of the thumb and index to the surface of the object.

Please let us know how you get on?

Hi, first of all thanks for the link, I will look for it.

Currently I added a boolean variable inside the rigged hand script that tells me if a grab/pinch is happening on not, modifying its value through the interaction engine, and then I use this boolean inside the Rigged Hand script to not update the fingers that need to be locked.

Thanks and have a good day,
Eros.
