Overview
The Grab & Deform feature simulates pushing or pulling on soft tissue structures, such as the spinal canal or ligaments. It uses a viscoelastic physics model for realistic behavior.Activation
Toggle Grab mode in the endoscope controls panel.Usage
With grab mode active:- Click and drag on a mesh surface to deform it.
- The tissue responds with viscoelastic spring-back behavior.
- A J-curve nonlinear response mimics real soft tissue mechanics.
Constraints
- Deformation is limited to a maximum of 10 mm displacement.
- Vertebral bodies act as collision boundaries — tissue cannot be pushed through bone.
- Only soft tissue structures (canal, ligaments) respond to deformation; bone structures are rigid.
