Reverse engineering with subdivision surfaces
Reverse engineering is concerned with the reconstruction of surfaces from three-dimensional point clouds originating from laser-scanned objects. We present an adaptive surface rec...

Combined Laplacian and Optimization-based Smoothing for Quadratic Mixed Surface Meshes
Quadratic elements place stringent requirements on a surface mesh smoother. One of the biggest challenges is that a good linear element may become invalid when mid-side nodes are ...

Ray-Tracing Triangular Trimmed Free-Form Surfaces
This paper presents a new approach to rendering triangular algebraic free form surfaces. A hierarchical subdivision of the surface with associated tight bounding volumes provides ...

Spectral quadrangulation with orientation and alignment control
This paper presents a new quadrangulation algorithm, extending the spectral surface quadrangulation approach where the coarse quadrangular structure is derived from the Morse-Smal...

Interference Detection for Subdivision Surfaces
Accurate and robust interference detection and ray-tracing of subdivision surfaces requires safe linear approximations. Approximation of the limit surface by the subdivided contro...
