Modeling of surfaces with fair reflection line pattern

J. Loos, G. Greiner, H.-P. Seidel
1999 Proceedings Shape Modeling International '99. International Conference on Shape Modeling and Applications  
Inspection of reflection line patterns is a standard way to check the quality of free form surfaces.  ...  In this paper, we describe an approach which enables the designer to control during the modeling process the reflection line pattern by approximating a specified family of reflection lines.  ...  The right picture shows the faired surface, which was computed by approximating the line pattern of the middle picture.  ...

Shape Optimization Using Reflection Lines [article]

Elif Tosun, Yotam I. Gingold, Jason Reisman, Denis Zorin
2007 Symposium on geometry processing : [proceedings]. Symposium on Geometry Processing  
Reflection lines are commonly used for surface interrogation, as they capture many essential aspects of reflection distortion directly, and clearly show surface imperfections that may be hard to see with  ...  In this paper, we propose the use of functionals based on reflection lines for mesh optimization and editing.  ...  The reflection line pattern in our model is created by long line-shaped light sources aligned with a unit length vector a (Figure 2 ).  ...

Electromagnetic cavity effects from transmitters inside a launch vehicle fairing

Dawn H. Trout, Parveen F. Wahid, James E. Stanley
2009 2009 IEEE International Symposium on Electromagnetic Compatibility  
Conclusions: This study shows how the fields increase in the fairing model lined with a good conductor, the effects of the various blanketing materials that typically line the fairing walls in launch vehicles  ...  An is the surface area in square meters. n is a designator for each surface type. A scaled fairing model as well as an empty cavity was used to validate this method with some reasonable correlation.  ...  Future Work: Testing should be modified to examine more points in the cavity to identify changes in eigenmodes especially with the addition of a spacecraft model.  ...

Spectral Prediction of Juxtaposed Halftones Relying on the Two-by-Two Dot Centering Model

Vahid Babaei, Roger D. Hersch
2013 Journal of Imaging Science and Technology  
Since this model requires a large calibration set, the authors use an estimation technique which predicts more than 90% of the two-by-two calibration pattern reflectances by measuring less than 10% of  ...  However, this model may not predict the color of juxtaposed halftones, since the effective surface coverages of colorants and of possible colorant overlaps are unknown.  ...  To perform a fair comparison, we create juxtaposed halftones with colorant surface coverages meeting the constraints of the YNSN model.  ...

Removing local irregularities of triangular meshes with highlight line models

JunHai Yong, BaiLin Deng, FuHua Cheng, Bin Wang, Kun Wu, HeJin Gu
2009 Science in China Series F Information Sciences  
The new technique improves not only the shape quality of the mesh surface, but the highlight line model as well.  ...  The highlight line model is a powerful tool in assessing the quality of a surface. Its presence increases the flexibility of an interactive design environment.  ...  Acknowledgements We thank Leif Kobbelt for providing us with the Volkswagen Beetle model.  ...

Van der Waals Interaction between Polymer Aggregates and Substrate Surface Analyzed by Atomic Force Microscope (AFM)

Akira Kawai, Daisuke Inoue
2002 Journal of Photopolymer Science and Technology (Fotoporima Konwakai shi)  
Based on the aggregation model, it is clarified that exposing the substrate to HMDS vapor acts to weaken the peeling strength of the resist pattern.  ...  It is clarified that a part of polymer aggregates condensed at pattern bottom have no contribution to the interaction with the substrate because the interaction length becomes short.  ...  On the other hand, the dashed line, b-b', is approached the substrate surface compared with the line a-a'.  ...
