Abstract
This paper presents a method for designing spherical curves by two weighted spatial rotations. This approach is for the design of interpolating spherical curves and orientation interpolation. The same approach can be used for smoothing orientations or corners on a sphere. The designed curves have the following features: C1 continuity, local control, and invariance under orthogonal transformations of coordinate systems.
