Abstract

The invention provides a behavior modeling method of a moving vehicle in a virtual environment. The problem about realistic display of the posture of the moving vehicle on a natural uneven earth surface is researched. Representation of moving behaviors of moving vehicle dynamic models on a regular pavement is relatively simple, but it is much more complex to correctly represent moving postures of the dynamic models on irregular uneven pavements. Along with irregular unevenness of terrains in the virtual environment, postures of the vehicle need to be correspondingly changed along with change of local features of terrains making contact with a vehicle body under the action of gravity of the vehicle. According to the modeling method, posture display parameters adaptive to terrain changes are calculated through a defined vehicle supporting plane and are displayed in a three-dimensional mode, and the dynamic process of moving of the vehicle is effectively and vividly represented.

Description

technical field [0001] The invention relates to a behavior modeling method of the motion posture of a virtual vehicle. Background technique [0002] The 3D model dynamic display technology makes full use of human visual characteristics, expresses various information through graphics and animation, and can realize the graphics display of virtual reality and other visual dynamic simulation systems, so it has become a research hotspot in recent years. [0003] The physical objects in the virtual environment are divided into dynamic and static. For dynamic objects, in addition to having geometric shapes, they also need to move in a convincing manner according to their respective behavioral laws. Only in this way can the realism of the virtual world be reflected, which is the "immersion" required by virtual reality. Therefore, the behavior modeling of virtual objects has become a key technology of virtual reality. [0004] The task of behavior modeling is to explore a model tha...
