We developed real-time generalized mesh cutting methods for surgical simulation. These techniques enable precise virtual dissections and corrections on various anatomical models.

Area of Science:

  • Computer Graphics
  • Medical Simulation
  • Computational Geometry

Background:

  • Accurate mesh manipulation is crucial for realistic surgical simulations.
  • Existing methods often lack the flexibility to handle diverse mesh types and cutting scenarios.

Purpose of the Study:

  • To introduce novel schemes for real-time generalized mesh cutting.
  • To demonstrate the application of these schemes across different mesh representations and cutting tool configurations.

Main Methods:

  • Implementation of cutting algorithms for single and multiple surface objects.
  • Adaptation of methods for hybrid and volumetric meshes.
  • Utilizing virtual tools with single and multiple cutting surfaces for generalized cutting.
