| PROJECT DESCRIPTION |
Virtual mock-up and PresentationApplications based on the P2V software (Virtual Vehicle Presentation) allow a realistic visualization of the digital mock-up very early in the vehicle development process, as well as a presentation of those Renault vehicles, using the latest technologies in Virtual Reality. The user can discover and visit both inside and outside of the vehicle at its convenience. He or she can choose the model type, the body paint, the options available and thus can modify the vehicle configuration and observation position (open the doors, lower the seats, change the position of passenger seat,…). There are many potential applications for Renault, from virtual mock-up to vehicle presentation at sales point or internet. System architectureWhen being used in its digital mock-up version, the P2V application runs on a CAD/CAM workstation and performs geometry computation and high-quality visual rendering. In its immersive version, the system can be used with a stereoscopic head mounted display or displayed on a power wall, in this case users are equipped with corresponding stereoscopic glasses. ![]() |
It also allows i-collaborative mode, using a 3D Workstation with high quality, scale-one and stereoscopic visualization of a vehicle cockpit, for several users. The points of view of two users are captured simultaneously and taken into account in the image generation module. More specifically, virtual reality devices can be plugged to the system, such as force feedback systems, cyber gloves or position sensors. These devices allow to be deeper immersed in a virtual vehicle. The visualization module is available on SGI/Irix, PC/Linux or PC/Windows operating systems. Interactivity and immersionThe system is called interactive because images are computed in real-time according to data captured by a usual mouse, a 3D mouse or a position sensor, allowing automatic update of the observation point of view. The interactivity is also being enhanced with animations, geometry selectors or colors and textures selection. The system is called immersive when using a visualization head mounted display (the operator is isolated from his or her environment), or stereoscopic images projected on a screen. The computed images are different for each eye, which provides with a relief perception of the virtual world . |
