A Visibility Sphere Marching algorithm of constructing polyhedral models for haptic sculpting and product prototyping

ROBOTICS AND COMPUTER-INTEGRATED MANUFACTURING, 21(1), 19–36.

By: W. Zhu n & Y. Lee n 

author keywords: polyhedral model; CAD/CAM; virtual prototyping; NC simulation; haptic sculpting; Dexel volume model
TL;DR: The proposed visibility sphere marching algorithm consists of three sub-algorithms: roof and floor covering, wall-building, and hole-filling algorithms that can be used in virtual sculpting, CAD/CAM, numerically controlled machining verification and rapid prototyping. (via Semantic Scholar)
