Modeling of surfaces with fair reflection line pattern
1999
Proceedings Shape Modeling International '99. International Conference on Shape Modeling and Applications
Preserved Fulltext
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. ...

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 ). ...

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. ...

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. ...
