Rationalization of Freeform Surfaces
An ever broader availability of freeform designs together with an increasing demand for product customization has lead to a rising interest in efficient physical realization of such designs, the trend toward personal fabrication. Not only large-scale architectural applications are (becoming increasingly) popular but also different consumer-level rapid-prototyping applications, including toy and...
متن کاملSliding contact between freeform surfaces
This paper deals with the sliding-contact constraint equations describing the relative motion of two freeform surfaces, assuming that the surfaces can have arbitrary curvature in 3D space. The sliding-contact equations are developed either for the non-penetration condition and for the surface-tangency condition. Both are differentiated twice in time in order to allow a straightforward applicati...
متن کاملInteractive Line Art Rendering of Freeform Surfaces
In recent years, synthetically created line art renderings have reached quality levels that are aesthetically pleasing. Moreover, the sketch based approach was found to be quite capable at conveying geometrical information in an intuitive manner. While a growing interest in this type of rendering method has yielded successful and appealing results, the developed techniques were, for the most pa...
متن کاملThickening Freeform Surfaces for Solid Fabrication
Purpose: Given an intersection-free mesh surface S , we introduce a method to thicken S into a solid H located at one side of S . By such a surface-to-solid conversion operation, industrial users are able to fabricate a designed (or reconstructed) surface by rapid prototyping. Design/methodology/approach: In this paper, we first investigate an implicit representation of the thickened solid H ac...
متن کاملC∞ Smooth Freeform Surfaces Over Hyperbolic Domains
Constructing smooth freeform surfaces of arbitrary topology with higher order continuity is one of the most fundamental problems in shape and solid modeling. Most real-world surfaces are with negative Euler characteristic number χ = 2 − 2g − b < 0, where g is genus, b is the number of boundaries. This paper articulates a novel method to construct C∞ smooth surfaces with negative Euler numbers b...
