Subdivision surfaces are a powerful model widely used in geometric modelling. Controlling the accuracy of the approximation of the limit surface often involves the computation of the distance between the control mesh and the limit surface. Nevertheless, the a priori level (or depth) of subdivision based on a distance criterion has not yet been expressed. The goal of this paper is thus to comput...

background: previous anatomic and radiological studies have described the relationship of the clavicle to major neurovascular structures in healthy subjects. we were curious about this relationship in patients with a clavicle fracture and if it is different from non-fractured clavicles.   methods: we retrospectively identified all patients with a clavicle fracture between july 2001 and october ...
