Research on Multi-resolution Isosurface Extraction Method for 3D Scalar Field

Isosurface extraction and rendering of 3D scalar field is an important method in visual analysis of scalar field data. Traditional isosurface extraction algorithm does not take into account the characteristics of the scalar field itself. In this paper, a 3D scalar field multi-resolution isosurface extraction method is proposed to improve the efficiency of isosurface extraction and rendering. This method not only deals the multi-resolution of the 3D scalar field before the isosurface extraction, but also ensures the integrity of the isosurface in the subsequent isosurface extraction process. The experimental results show that the method can greatly improve the efficiency of isosurface extraction and rendering on the basis of less effect on isosurface.
