This paper summarizes several different definitions of cone quasiconvex vectorfunctions proposed in different literatures and discusses the relations among them.
Since the MASS vectorfunctions are much faster (by a factor of up to about 30) than a repeated call to a standard library function, the resulting performance improvement can be substantial.
To analyze and display the contact of skew bevel involute gears, a mathematic model was established by vector gyration and coordinate transform of circle vectorfunctions and sphere vectorfunctions.
