Efficient evaluation of functionally represented volumetric objects.

There are several approaches to representing shapes in computer graphics. One of the ways to describe objects and operations is Function Representation (FRep). In FRep, a geometric object is de ned by a single continuous real-valued function of point coordinates. Generally geometric modelling is conducted in order to achieve visual outcome. In FRep the transformation of a function into a visual representation relies on extensive sampling of the function. The computational cost of the sampling can cause adverse e ects during applications runtime. In this thesis the problem of e cient evaluation of the de ning function is discussed. An observation is made on wide range of operations and primitives within FRep and their suitability for parallelization. Furthermore, a new novel method is proposed to distribute FReps computational workloads on parallel hardware devices such as graphics programming units and multi-core processors

Proceedings of the ECCOMAS Thematic Conference on Multibody Dynamics 2015

This volume contains the full papers accepted for presentation at the ECCOMAS Thematic Conference on Multibody Dynamics 2015 held in the Barcelona School of Industrial Engineering, Universitat Politècnica de Catalunya, on June 29 - July 2, 2015. The ECCOMAS Thematic Conference on Multibody Dynamics is an international meeting held once every two years in a European country. Continuing the very successful series of past conferences that have been organized in Lisbon (2003), Madrid (2005), Milan (2007), Warsaw (2009), Brussels (2011) and Zagreb (2013); this edition will once again serve as a meeting point for the international researchers, scientists and experts from academia, research laboratories and industry working in the area of multibody dynamics. Applications are related to many fields of contemporary engineering, such as vehicle and railway systems, aeronautical and space vehicles, robotic manipulators, mechatronic and autonomous systems, smart structures, biomechanical systems and nanotechnologies. The topics of the conference include, but are not restricted to: ● Formulations and Numerical Methods ● Efficient Methods and Real-Time Applications ● Flexible Multibody Dynamics ● Contact Dynamics and Constraints ● Multiphysics and Coupled Problems ● Control and Optimization ● Software Development and Computer Technology ● Aerospace and Maritime Applications ● Biomechanics ● Railroad Vehicle Dynamics ● Road Vehicle Dynamics ● Robotics ● Benchmark ProblemsPostprint (published version
