Three-dimensional virtual human in the military criminal investigation training system

摘要

To improve the fidelity of virtual human model, at the same time to ensure continuity of human movement and to reduce the size of the model impacting on system performance, combined with multiple software and algorithms to solve the conflict between the two. According to three-dimensional virtual human in the military criminal investigation training system, create geometric model in Poser, simplify under the premise of its fidelity, set DOF nodes in accordance with DI-Guy'S joint requirements, and build skeleton that the human model is handled as multi-body system. Deal with cracks while human movement, and ultimately a variety of the characters and their animation in the system are completed. The instance shows that: The model created in Poser can still maintain a better fidelity after simplification, build skeleton and debug human movement in DI-Guy, the approach overlapping can be used to solve model cracks. This method can largely improve the fidelity of character models and reduces the size of the model, thus improving the coherence of human movement and system operating performance.
