Blast Features and Requirements for Fracturing Osseous Models

Abstract

Fracturing osseous models is a challenge in computer graphics. The generation of bone fractures is important in the field of traumatology mainly for training. This field of research can provide specialists with a rich and varied amount of fracture cases. Traditionally, the generation of bone fractures has been carried out by using a finite element method (FEM) approach. Nevertheless, this approach requires a precise physical information of the model and the incoming forces that are not usually available. Thus, we propose a geometric approach to avoid these initial requirements. This paper evaluates the adequacy of a given generic destruction library (Blast) within the bone fracture generation context. Our aim is to assess its suitability to provide varied, uncommon cases and morphologically rich fractures in the field of bone fractures. In order to achieve quality results, bone models are evaluated at different scales, spanning from the macroscale to the nanoscale. This study highlights the advantages and shortcomings of the revised library. Additionally, it provides a groundwork for the use of this library in the context of fracturing osseous models as well as a set of addons needed to get a tool specifically designed for this aim.
