[204] Citation: Abstract
An algorithm is described for fast rendering of surfaces for haptic interaction with multiple fingers.
The algorithm uses a human-defined geometrical map to quickly cache surface triangles for
constant time solution of the collision detection problem. The map is a 1, 2, or 3 dimensional
manifold onto which it is easy to project the haptic interaction point. Dividing it's surface
into quantized bins allows easy reference to a small set of triangles which can be checked for
collision. Although the algorithm relies on some one-time manual input (i.e. defining the contact
map), it represents a significant increase in speed without a substantial memory penalty.
