Creeping Ray Tracing Algorithm for Arbitrary NURBS Surfaces Based on Adaptive Variable Step Euler Method

International Journal of Antennas and Propagation, 2015
Although the uniform theory of diffraction (UTD) could be theoretically applied to arbitrarilyshaped convex objects modeled by nonuniform rational B-splines (NURBS), one of the great challenges in calculation of the UTD surface diffracted fields is the ...

NURBS Reconstruction and Optimization Method for the Tooth Surface after Simulation Process of Spiral Bevel Gear

Jixie chuandong, 2016
For lower accuracy of tooth surface of outputted model after simulation process for spiral bevel gear,some methods cubic NURBS reconstruction and optimization of tooth surface are proposed by combining with the advantages and features of the Non- Uniform
