On the rendering of surfaces

A. R. Forrest
1979 Proceedings of the 6th annual conference on Computer graphics and interactive techniques - SIGGRAPH '79  
The paper discusses several possible renderings, including various line drawings methods, realistic and functional shading, and combinations of line drawings and smooth shading.  ...  Despite the relative sophistication of modern surface design systems, many graphical renderings of surfaces are rather crude.  ...  ACKNOWLEDGEMENTS The author is grateful to the Computer Science Department, University of Utah, for support and the use of facilities in preparing this paper, and to Brian Barsky and Spencer Thomas for  ...

Path Planning of a Laser-scanner with the Control of Overlap for 3d Part Inspection

Nguyen Duy Minh Phan, Yann Quinsat, Sylvain Lavernhe, Claire Lartigue
2018 Procedia CIRP  
This paper proposes a new approach to scan path planning for automated inspection of manufactured parts with an industrial robot based on the control of the overlap between 2 successive scanning paths.  ...  The novelty lies in the use of the least-squares conformal map, which stretches a 3D surface on a 2D plane.  ...  Dorian Verdel for their technical assistance in our experimental work.  ...

Rational hypersurface display

Chanderjit L. Bajaj
1990 Proceedings of the 1990 symposium on Interactive 3D graphics - SI3D '90  
The method relies on initially constructing the rational parametric equations of the implicitly defined hypersurfaces, and then polygonalizing thes e hypersurfaces by an adaptive generalized curvature  ...  Abstrac t Algorithms are presented for polygonalizing implicitl y defined, quadric and cubic hypersurfaces in n > 3 dimensional space and furthermore displaying their projections in 3D .  ...  Acknowledgements : I sincerely thank Insung Ihm an d Andrew Royappa for the many hours they spent in fron t of the graphics workstation, helping me visualize in fou r and higher dimensional space .  ...

2012 Lecture Notes in Computer Science  
An unfold method was also developed for the left atrium (LA) using trimmed B-spline surfaces.  ...  The method was applied to 5 patient data sets and its utility was demonstrated for displaying information from delayed enhancement MRI of patients that had undergone radio-frequency ablation.  ...  Each scan line generates a contour. It is ensured that no multiple disjoint contours are generated for a single scan line.  ...

Interactive techniques for implicit modeling

Jules Bloomenthal, Brian Wyvill
1990 Computer graphics  
Principally this is due to the difficulty of controlling the shape of implicit surfaces while displaying the changes quickly enough for use within an interactive design environment.  ...  The interactive design of such surfaces has not, however, received the same attention as has the design of parametric surfaces.  ...  Finally, we thank Rich Riesenfeld who succinctly noted, more than a decade ago, that surface design was an interesting problem.  ...

Dorian Verdel for their technical assistance in our experimental work.  ...  The method we developed, called ISOvScan for Iso-Overlap Scan path, presents three main steps: stretching the 3D mesh surface on a 2D parametric surface using the LSCM method generating the view points  ...  Limitations One limitation of the ISOvScan method is that the interval between the passes of the scan path in 3D space cannot be kept constant for all the scan path for high-curvature surfaces.  ...
