Surface-surface intersection with validated error bounds
This thesis presents a robust method for tracing intersection curve segments between continuous rational parametric surfaces, typically rational polynomial parametric surface patches. Using a validated ordinary differential equation (ODE) system solver based on interval arithmetic, we obtain a …

Intersection of B-spline surfaces by elimination method
… complex models. However, the task of finding the intersection curve between two surfaces has remained a difficult one. Presently, most of the research done in this area has resulted in various subdivision techniques. These subdivision techniques are based on approximations of the surface using …

Geometric Trimming and Curvature Continuous Surface Blending for Aircraft Fuselage and Wing Shapes
… shape and a wing shape at a closed trimming intersection curve, and verifies the properties of the newly created surface. In order to distinguish how well the new surface approximates the original, an error comparison tool developed in MATLAB has been employed.

Computing the intersection of two quadrics through projection and lifting
… a expressão analítica da curva de projeção (cutcurve) que deve ser definida numa região plana delimitada pelas curvas silhueta (curvas de projeção dos limites de ambas quadricas); um método para determinar pontos singulares da curva de projeção e pontos comuns entre a cutcurve e as curvas de …
