Area of Science:

• Computer Graphics
• Medical Simulation
• Computational Physics

Background:

• Realistic virtual surgery simulation requires accurate smoke modeling from electrocautery.
• Traditional vortex particle methods offer visual fidelity but incur high computational costs.

Purpose of the Study:

• To address the computational expense and collision complexities in smoke simulation.

Main Methods:

• Proposed the 3D Vortex Particles in Cube Algorithm (3D-VPICA) for efficient smoke simulation.
• Introduced the Auxiliary Particles Algorithm (APA) to handle smoke-surface collisions accurately.

Main Results:

• 3D-VPICA reduces computational complexity from O(N^2) to O(N) + O(Mlog2M).
• APA ensures boundary condition satisfaction during smoke collisions with irregular surfaces.
• The combined methods demonstrate faster simulation speeds and successful collision handling compared to traditional approaches.

Conclusions:

• The 3D smoke simulation method is effectively integrated into a virtual surgery system.
• The simulation accurately represents smoke dynamics during electrocautery procedures, enhancing surgical realism.
