In this paper we present an automated system for visualizing dressed virtual bodies using CAD cloth data for the garments. The system can be used during the garment design process to judge the look and the fit of the garment without the necessity of creating a real prototype, which is expensive and time consuming. The cloth patterns are created by using a common textile 2D CAD system. In order to visualize the garment in 3D the user chooses a suitable virtual body and exports the patterns into our system. This task only comprises the marking of the seaming lines and the naming of the patterns. A process that is more or less automatically done within a textile CAD system. After importing the data into our system the patterns are pre-positioned automatically and simultaneously around the virtual human body. The underlying algorithm ensures that the final fitting can be computed fast and efficiently. It is even possible to process several pieces of clothing at once. Typically, the simulation is based upon a parameterized particle system. However, a practicable solution has to compute the draping results as fast as possible. Therefore our simulation algorithm only takes into account the most important physical cloth parameters having significant impact during the visualization and being needed for judging the fit of the garment. The high quality visualization of the dressed virtual bodies includes texturing, shadowing and selfshadowing. We achieve real-time rendering by making extensive use of the features of modern 3D graphics hardware e.g. vertex shaders. Our dressing method cannot only be used during the clothing design process but in other applications for example a virtual boutique as well.
