| 摘 要： | INTRODUCTION The first phases of the product life cycle are almost completely digitalized nowadays. Single parts or complete product models are modeled with 3D CAD solutions. Assembling single parts to digital mockups (DMUs) is important for checking the de- pendencies between the parts and detecting conflicts. Due to their complexity, such data is managed in specialized Product Data Management (PDM) sys- tems. They gained an increasing importance in many industries during the last d…

| Abstract: | In this paper we present the MEMPHIS middleware framework for the integration of CAD geometries and assemblies with derived
Virtual Reality (VR) models and its specific meta data and attributes. The goal of this work is to connect real time VR applications,
especially for the Design Review, with enterprise software storing and managing CAD models (Product Data Management—PDM).
The preparation of VR models requires expert knowledge, is time consuming, and includes selection of required CAD data, tessellation,
healing of unwanted gaps, applying materials and textures, and special surface and light effects. During the Design Review
process, decisions are made concerning the choice of materials and surface forms. While materials can be switched directly
on the VR model, the modification of part geometries must be made on the CAD model. Our system synchronizes modifications
of the original CAD geometries and of attributes that are relevant for the realistic rendering using the PLM Services standard.
Thus, repeated work for the VR preparation can be avoided.
