PARADIGMAS DE REPRESENTAÇÃO DE MODULAÇÃO DE ALVENARIAS EM FERRAMENTAS BIM

New CAD tools which support the BIM (Building Information Modeling) concept are based on 3D modeling of buildings by instancing objects from component families. Some of these objects have detailed geometry while others are restricted to their outer boundaries. For example, in the “wall object” this representation usually is limited to its external faces, and a list of layers is used to represent its internal composition (core and finishes). This representation makes the file light, favoring the application performance. However, in designs that require a higher detail level than this solution supports, like the Masonry Design for Production (MDP), a complete 3D representation of wall 10.4237/gtp.v4i2.??

A programming environment for high-performance volume visualization applications

Abstract Volume visualization is an important tool in many scientific applications, requiring intensive processing and dealing with large amounts of data. For interactive and specialized applications one needs to use high-performance computing techniques. This paper describes the Parallel Volume Visualization (PVV) toolkit. PVV is an Application Programming Interface (API) for developing volume visualization applications. It was designed to be easily portable across high performance parallel computers such as shared memory and distributed memory parallel computers. Good speed-up rates have been achieved with a preliminary implementation of PVV on a SGI 4D480 multiprocessor.
