how VR Hand grab the object(rigidbody, multibody.. etc)

Post by JeonMong » Mon Mar 20, 2017 8:34 am

I know that VR hand has a lot of flexible sensor.
so VR hand transfer data to pc according moving user finger and draw this hand in virtual reality.

I tried to grab the object using VR hand.
when VR hand grab the object(box, Cylinder .. etc), the object is unstable.
but in bullet 2.86 official video, grabbing motion is very stable.

I wonder how VR hand grab the object????
need force feedback?????? add constraint?????
I don't know how VR hand grab the object..

I am fairly certain it is done similar to mouse picking on the 2d screen using btPoint2PointConstraint but this time it is moving the constraint in 3d space (one for each finger on the object)

If it's not that, then it may be similar to the Gripper Grasp Example in the Bullet Browser
