Over the past decade, computer software and hardware technology with the rapid development of the field of virtual reality in a number of advanced development tools and   hardware equipment, greatly improving the virtual scene and create a virtual environment such as human-computer interaction capabilities. Users make use of development tools, coupled with virtual reality hardware, and can be separated from the outside world, make it feel immersive and more realistic to study the object of observation, more natural, more realistic interaction with objects. However, this type of software to deal with most of the objects are also limited to static or a simple movement of objects, could not do the complex simulation of movement and power. At the same time, the dynamics of traditional software interface as a result of the complexity of poor operability, it is difficult to become an effective means of design and development.

      The CM-LABS has developed the multi-body dynamics virtual simulation system for Vortex, stressed that both the accuracy and real-time. It created an interactive simulation of the operating environment, as can the realization of 3D simulation games; at the same time it is different from the general computer animation software, the establishment of mathematical models and optimization of the calculation of outstanding, not just the pursuit of shape, but also a more high calculation accuracy and computing speed.
