abstract = "While real time computer graphics rely on a frame rate of 30
iterations per second to fool the eye and render smooth motion
transitions, computer haptics deals with the sense of touch, which
requires a higher rate of around 1kHz to avoid discontinuities.
The use of haptics on interactive applications as surgical
simulations or games, for instance, can highly improve the user
experience, and the sense of presence. However, its use in complex
simulations involving realistic rendering, deformable objects and
collision detection requires the development of very performing
algorithms. This paper presents an implementation of mass-spring
system adapted to CUDA implementation, and a novel method for
collision detection in haptic update rate. Important aspects of
the port to parallel programming and the GPU architecture are
addressed, as for example, strategy and frequency of memory
access. A quantitative experiment is also.",
