Rendering Pacioli’s Rhombicuboctahedron
نویسندگان
چکیده
We analyze the glass rhombicuboctahedron (RCO) appearing in a famous painting of Pacioli (1495), considering the extent to which it might agree with a physically correct rendering of a corresponding glass container half-filled with water. This investigation shows that it is unlikely that the painter of the RCO was looking at such a physical object. We then ask what a proper rendering of such an object might look like. Our computer renderings, which take into account multiple internal and external reflections and refractions, yield visual effects that differ strongly from their depictions in the painting. Nevertheless, the painter of the RCO has clearly succeeded in providing a rendering that appears plausible and aweinspiring to almost all observers.

Reading Luca Pacioli’s Summa in Catalonia: An early 16th-century Catalan manuscript on algebra and arithmetic ✩
This paper focuses on an anonymous Catalan manuscript of the early 16th century dealing with algebra and commercial arithmetic. More than half of it consists of a series of notes concerning parts of Luca Pacioli’s Summa de Arithmetica, Geometria, Proportioni et Proportionalità, while most of the rest is related to Joan Ventallol’s commercial arithmetic (1521). The use of a new kind of diagrams ...
متن کاملSegmentation Assisted Object Distinction for Direct Volume Rendering
Ray Casting is a direct volume rendering technique for visualizing 3D arrays of sampled data. It has vital applications in medical and biological imaging. Nevertheless, it is inherently open to cluttered classification results. It suffers from overlapping transfer function values and lacks a sufficiently powerful voxel parsing mechanism for object distinction. In this work, we are proposing an ...

To develop scaffold CAD libraries, the polyhedrons could be used in the scaffold libr...
متن کاملSpatial Relationship between Mandibular Third Molars and Inferior Alveolar Nerve using a Volume Rendering Software
Precise localization of the third molars in relation to the inferior alveolar nerve canal is critical from a clinical point of view and strongly affects the surgical treatment outcome. Recently, by using three-dimensional modeling software, the relationship of third molar root apices and inferior alveolar nerve canal can be better understood. In this study, the spatial relationship of two surgi...
