3D simulation of tool machining
(2001-12)
Report de recerca
Accés obertThis paper describes a three-dimensional tool machining simulation system. The initial tool and the grinding wheels are integrated with the machine-tool. The application reads and interprets the CNC program code that ... -
3D texture-based hybrid visualizations
(2003-01)
Article
Accés restringit per política de l'editorialIn this paper, the visualization of hybrid scenes that contain volume data and a fitted extracted surface is addressed. The proposed algorithm is based on a integrated octree-based representation: the ‘‘hybrid octree.’’ ... -
3D triangular mesh to represent the left ventricle volume of the heart
(2002-07-01)
Report de recerca
Accés obertThis report describes an algorithm for the generation of unstructured tetrahedral meshes from two triangular meshes: the internal and external walls of an object. The tetrahedral mesh thus obtained represents the volume ... -
A Brief on constraint solving
(2004-10-08)
Report de recerca
Accés obertWe survey the current state of the art in geometric constraint solving. Both 2D and 3D constraint solving is considered, and different approaches are characterized. -
A comparative study of navigation meshes
(Association for Computing Machinery (ACM), 2017)
Text en actes de congrés
Accés restringit per política de l'editorialA navigation mesh is a representation of a 2D or 3D virtual environment that enables path planning and crowd simulation for walking characters. Various state-of-the-art navigation meshes exist, but there is no standardized ... -
A cost-effective approach for developing application-control GUIs for virtual environments
(2006-03)
Comunicació de congrés
Accés obertIn this paper we present a new approach for fast development of application-control User Interfaces (UIs) for Virtual Environments (VEs). Our approach allows developers to build sophisticated UIs containing both simple ... -
A Framework for animation in global illumination environments
(1998-06)
Text en actes de congrés
Accés obertThis paper proposes a framework for the production of animations of high quality radiosity environments which makes use of the a-priori knowledge of the dynamic properties of the scene in order to exploit temporal ... -
A framework for network traffic analysis using GPUs
(Universitat Politècnica de Catalunya, 2010-01)
Projecte/Treball Final de Carrera
