Realistic deformation of 3D human blood vessels.
COMPUTER ANIMATION AND VIRTUAL WORLDS(2013)
摘要
We present a real-time algorithm for realistically deforming 3D human blood vessels, while automatically detecting and avoiding interference among a large number of blood vessels under deformation. Sweep surfaces are employed for this purpose. Using a dynamic bounding volume hierarchy, specially designed for sweep surfaces, we support collision detection and other related geometric computations in real time.
