基于曲率信息由曲线到曲面的重建与曲面检测

Surface reconstruction is an important topic of computer graphics. The traditional reconstruction method is diversity based of multi-forms data structures. But almost all of reconstruction methods were based on of the position of the vertex and there couldn’t get the position of vertex in some especially cases such as the vibration dynamical measurement of the flexible sheet structure. The sensors array was been designed for the curvature measurement on the surface and the dynamical surface has been reconstructed bases on the curvature and the arc-length. The reconstruction algorithm is a recursive computation according to geometrical conception of the curvature. The curves of the surface have been reconstructed in the process. Furthermore, with the technology of quadrilateral mesh subdivision, the detail of the surface has been shown. The surface reconstruction method is fast, with high approximation accuracy and is adaptive to models with arbitrary topology surface. The experiment shows a good agreement between the reconstruction surface and the experiment surface. Dynamic display was fast in real-time and the precise is high.
