Abstract Internet technology opens up another domain for building future CAD/CAM environment. The environment will be global, network-centric, and spatially distributed. In this paper, we present a new approach to network-centric virtual prototyping (NetVP) in a distributed design environment. The presented approach combines the current virtual assembly modeling and analysis technique with distributed computing and communication technology for supporting virtual prototyping activities over the network. This paper focuses on interoperability, shape representation, and geometric processing for distributed virtual prototyping. STEP standard and CORBA-based interfaces allow the bi-directional communication between the CAD model and virtual prototyping model, which makes it possible to solve the problems of interoperability, heterogeneity of platforms, and data sharing. STEP AP203 is utilized as a means of transferring and sharing product models. In addition, Attributed Abstracted B-rep (AAB) is introduced as 3D shape abstraction for transparent and efficient transmission of 3D models and for the maintenance of naming consistency between CAD models and virtual prototyping models over the network. Further, this paper discusses geometric processings needed for distributed virtual prototyping activities such as collision detection and interactive assembly modeling.

Abstract Network and Internet technology open up another domain for building future CAD/CAM environments. The environment will be global, network-centric, and spatially distributed. In this paper, we present Web-enabled feature-based modeling in a distributed design environment. The presented approach combines the current feature-based modeling technique with distributed computing and communication technology for supporting product modeling and collaborative design activities over the network. The approach is implemented in a client/server architecture, in which Web-enabled feature modeling clients, neutral feature model server, and other applications communicate with one another via a standard communication protocol. The paper discusses how the neutral feature model supports multiple views and maintains naming consistency between geometric entities of the server and clients as the user edits the part in a client. Moreover, it explains how to minimize the network delay between the server and client according to dynamic feature modeling operations.

This paper adress the problem of supporting collaboration among designers in a distributed design environment. Our goal is to allow designers to work synchronously even though they are geographically dispersed. The collaboration support is based on shared object spaces as technological infrastructure and its methodology is based on Pair Programming. It was implemented using Jini/Javaspaces and it was incorporated in the Cave2 CAD framework. The implemented collaboration support is availabre as a servicee that ca be requested by the design tolls and it allows design data sharing and facilitates the experience sharing among designers. The proposed approach was validated with a case stufy on a diagram editor.

Virtual Platform

An overview of a virtual design environment (virtual platform) developed as part of the European Commission funded VRShips-ROPAX (VRS) project is presented. The main objectives for the development of the virtual platform are described, followed by the discussion of the techniques chosen to address the objectives, and finally a description of a use-case for the platform. Whilst the focus of the VRS virtual platform was to facilitate the design of ROPAX (roll-on passengers and cargo) vessels, the components within the platform are entirely generic and may be applied to the distributed design of any type of vessel, or other complex made-to-order products.

Abstract This paper proposes an algorithm for streaming manifold solid models and NURBS geometry. A neutral streaming representation consisting of a nodes graph is encoded by a one-dimensional dynamic stack. The encoded model is transmitted over the Internet, where a two-dimensional dynamic stack decodes and reconstructs the solid model. The time and storage complexity of the algorithm are investigated. An example of streaming a solid model, resulting from a proof-of-concept implementation, is demonstrated.

Analysis And Design

Developments in simulation technology that enable a qualitatively new virtual prototyping approach to design of mechanical systems are summarized and their integration into an engineering design environment is illustrated. Simulation tools and their enabling technologies are presented in the context of vehicle design, with references to the literature provided. Their implementation for design representation, real-time driver-in-the-loop simulation, dynamic performance simulation, dynamic stress and life prediction, maintainability analysis, design sensitivity analysis, and design optimization is outlined. A testbed comprised of computer aided engineering tools and a design level of fidelity driving simulator that has been developed to demonstrate the feasibility of virtual prototyping simulation for mechanical system design is presented. Two 1994 demonstrations of this capability for vehicle design are presented, to illustrate the state of the technology and to identify challenges that remain in making virtual prototyping simulation an integral part of mechanical system design in US industry.

The design and test of Multi-Processor System-on-Chips (MPSoCs) and development of distributed applications and/or operating systems executed on those hardware platforms is one of the biggest challenges in today’s system design. This applies in particular when short time-to-market constraints impose serious limitations on the exploration of the design space. The use of virtual platforms can help in decreasing the development and test cycles. In this paper, we present a cloud-based environment supporting the user in designing heterogeneous MPSoCs and developing distributed applications. Therefore, the design environment generates virtual platforms automatically allowing fast prototyping cycles especially in the software development process, and exports the design to a hardware flow synthesizing compatible FPGA designs. The extension of the peripheral models with debug information supports the developer during test and debug cycles and avoids the need of adding special debug codes in the application. This improves the <br />readability, portability and maintainability of produced software. Additionally, this paper presents the benefits of using cloud-based design environments in engineers’ trainings and educations. Therefore, the framework supports testing the system including complex software stacks with prerecorded data or testbenches.
