Equiareal parameterizations of NURBS surfaces
The equiareality of NURBS surfaces greatly affects the results of visualization and tessellation applications, especially when dealing with extruding and intruding shapes. To improve the equiareality of given NURBS surfaces, an optimization algorithm using the Mobius transformations is presented in this paper.

Interactive Rendering of Deforming NURBS Surfaces
Non‐uniform rational B‐splines (NURBS) has been widely accepted as a standard tool for geometry representation and design. Its rich geometric properties allow it to represent both analytic shapes and free‐form curves and surfaces precisely. Moreover, a set of tools is available for shape modification or more implicitly, object deformation.

NURBS-Based Parametric Design for Ship Hull Form
Recently, the NURBS technique has been widely used in the 3D design software for ships. However, in most research, the NURBS technique is only applied to the mathematical representation of hull curves and surfaces, and the parametric deformation of hull ...

Large Depth-of-Field, Large Eyebox, and Wide Field-of-View Freeform-Holographic Augmented Reality Near-Eye Display. [PDF]
This study proposes an augmented reality (AR) near‐eye display system that simultaneously achieves a large depth‐of‐field (DOF) from 0.25 to 10 m, a wide 50° field‐of‐view (FOV), and a 10 mm × 10 mm viewing eyebox, while maintaining high display performance, good optical see‐through viewing capability, and a compact system form factor.
