This paper presents some problems and solutions in the domain of dynamic simulation and 3D interaction in virtual reality. First, we handle the trade-off problem between precision and interactivity for the dynamic simulation of a large number of moving solid bodies. Next, in the framework of deformable object interactions we introduce a 3D cutting algorithm including force feedback.

We perform 3D lithography simulations by using a finite-element solver. To proof applicability to real 3D problems we investigate DUV light propagation through a structure of size 9μm × 4μm × 65 nm. On this relatively large computational domain we perform rigorous computations (No Hopkins) taking into account a grid of 11×21 source points with two polarization directions each. We obtain well co...

Displaying facial motions such as crying or laughing is difficult to achieve in real-time simulations and games. Not only because of the complicated simulation of the physical characteristics such as muscle motions or fluid simulations, but also because one needs to know how to control these motions on a higher level. In this thesis, we propose a method that is an extension of the MPEG-4 Facial...

the present work reports and discusses the results of a 3d simulation of the injection molding process of a rubber compound that includes the mold flling stage and  material curing, using the computer code is developed in “udf” part of the fluent 6.3 cae software. the data obtained from a rheometer (mdr 2000) is used to characterize the rubber material in order to fnd the cure model parameters ...

This paper presents a newly developed 3-Dimensional (3D) simulation system for Moving Mask Deep X-ray Lithography (MDXL) process, and its validation. The simulation system named X-ray Lithography Simulation System for 3-Dimensional Fabrication (X3D) is tailored to simulate a fabrication process of 3D microstructures by MDXL. X3D consists of three modules: mask generation, exposure and developme...

Our last years Soccer Simulation team AT Humboldt 2003 was mainly designed as a research testbed for long-term deliberation and realtime reasoning, cooperative behavior in MAS, CBR-aided decision making and scalable behavior control mechanisms. The main goal was to implement and to evaluate the double pass architecture (DPA). This was always done with regard to the transition of the Simulation ...

In this paper we describe a concept to manage and develop a web based virtual 3D scene, based on CityGML LoD 2 models, DTM tiles, ortho-photos and energy simulation results of specific heating demand and photovoltaic potential generated from SimStadt simulation platform, by integrating it on ESRI 3D City Information Model (3DCIM) platform. The final output results into a web based 3D visualizat...

This paper presents an integrated methodology for building a virtual factory. This methodology integrates discrete event simulation directly to 3D animation with its novel methods that analyze and convert discrete simulation results into animation events to trigger 3D animation. In addition, it constructs a 3D animation framework for the visualization of discrete event simulation. This framewor...

flow unit characterization plays an important role in heterogeneity analysis and reservoir simulation studies. usually, a correct description of the lateral variations of reservoir is associated with uncertainties. from this point of view, the well data alone does not cover reservoir properties. because of large well distances, it is difficult to build the model of a heterogenic reservoir, but ...
