Application of haptic navigation to modify free-form surfaces through specified points and curves
Pages 377 - 388
Abstract
In this paper, we propose a method which modifies free-form surfaces to pass through not only specified points but also specified curves with the assistance of haptic navigation. Using the method, designers of aesthetic shapes such as a car body can manipulate the model of the shape in real-time looking at its stereoscopic image and feeling its haptic sensation as if there were a clay model. The haptic navigation helps designers letting them capture and recognize the object easily and constraining their operation to the appropriate direction or along the specified geometric element. In addition, the designers can get force feedback proportional to the modification quantity. To obtain a smoothly modified shape, we introduce correction functions to the given surface equations. A correction function distributes the effect of the change over the whole shape or the specified region according to the distance of the point in the normal direction of the given surface. The values of the correction function are 1 at the indicated point and 0 at the boundaries, and the shape is modified to keep the original smoothness. The distance values of the correction functions at the indicated points are determined to pass through all of them by solving a linear equation. To apply this to the specified curves including boundaries of a trimmed surface, we treat points composing the curve similarly for the correction functions of points by representing it with a Cardinal spline.

Gauss map computation for free-form surfaces
The Gauss map of a smooth doubly-curved surface characterizes the range of variation of the surface normal as an area on the unit sphere. An algorithm to approximate the Gauss map boundary to any desired accuracy is presented, in the context of a tensor-...

This paper presents a new approach to rendering triangular algebraic free-form surfaces. A hierarchical subdivision of the surface with associated tight bounding volumes provides for quick identification of the surface regions likely to be hit by a ray. ...
