This study introduces Haptics-based Dynamic Implicit Solid Modeling, a novel framework for interactive 3D design. It uses physics-based modeling and haptic feedback for realistic and intuitive manipulation of complex models.

Area of Science:

  • Computer Graphics
  • Geometric Modeling
  • Human-Computer Interaction

Background:

  • Traditional solid modeling lacks intuitive real-time manipulation and physical realism.
  • Existing methods struggle to integrate haptic feedback effectively for complex 3D design tasks.

Purpose of the Study:

  • To present a novel interactive solid modeling framework integrating haptic feedback with dynamic implicit functions.
  • To enable intuitive, physics-based manipulation and real-time editing of 3D models and point clouds.

Main Methods:

  • Developed a haptics-based dynamic implicit solid modeling framework using volumetric implicit functions.
  • Implemented a hierarchical fitting algorithm to reconstruct discrete datasets into continuous implicit functions.
  • Integrated a 3D haptic interface for force-feedback-driven sculpting and manipulation.
