Taschenbuch. Condizione: Neu. Neuware -In reverse engineering the detection of special classes of curves and surfaces generated by Computer Aided Curve and Surface Design often is based on the line congruence of normals and the GAUSS-image of such a surface. For surfaces with a 'kinematic generation', the congruence of normals b…elongs to a linear complex and this fact allows the detection via a line geometric treatment. Patch detection in case of general spline surfaces is not yet solved successfully. While the patch generation is at most invariant with respect to affine transformation, the normal congruence of the patch is an Euclidean concept. Therefore we can expect that connections between the patch and its congruence turn to be rather complicated already for (algebraic) Bézier surfaces. The analysis of the patch''s normal congruence is only the first step of the far more difficult investigation of a reflection or refraction congruence with respect to a given patch. This problem belonging to geometric optics would have explicit industrial applications, but is not the topic of this book. We restrict ourselves to an analysis of the normal congruence of Bézier patches.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In differential geometry of curves, there are many important properties and consequences. In the light of the existing studies, researchers always introduce new curves. Although, the differential geometry of curves in E^3 can be fo…und in many textbooks and in the contemporary literature on geometric modeling, there is little literature in E^3 and hardly in E^4 and E^n in the study of differential geometry of intersection curves. Some intersection curves have been studied by many geometers and obtained some interesting results. Here, we work with one of the important classes of surfaces which are called the implicit surfaces in a four- dimensional Euclidean space E^4. And we present formulas for computing the differential geometry properties of the tangential intersection curve of three implicit surfaces in Euclidean 4-space E^4. These properties include (the tangent T, the principle normal N, the binormal vectors (B1;B2) and the curvatures (1; 2; 3) of the intersection curve). Furthermore, we give examples to explain our main results. 128 pp. Englisch.
