Adaptive Tessellation of NURBS Surfaces. [PDF]

, 2003
NURBS surfaces are widely used in computer graphics, due to their great accuracy of design and reduced amount of data needed for representation. For real-time visualization, tessellation algorithms are needed, as they make use of the actual graphics hardware through the conversion of surfaces to triangle meshes. The existent algorithms for tessellation

NURBS-enhanced boundary element method for the Dirichlet boundary value problem of the three-dimensional Helmholtz equation

Mechanical Engineering Journal
We propose a collocation-based NURBS-enhanced boundary element method in which NURBS surfaces are directly used for exact geometry representation, while piecewise-constant basis functions are employed for field approximation.
