Smart modeling of bobsleigh track surface VR

This paper describes a smart method to model bobsleigh track surface. On real bobsleigh tracks, the cross-sectional shape is generally rectangular in the strait section, and in contrast, circular and banked in the curve section. In the first step, three-dimensional shapes of track surface are generated automatically based on these two kinds of cross-sectional shapes along the track centerline. In the second step, the most suitable parameters of track surface modeling, which consist of triangular patches is decided by evaluating the smoothness of sliding in dynamic simulation with Unity.
