摘要
Abstract
In order to observe 3D graphics, we rotate the scene around X,Y or Z axis, however, it s hard to rotate to the precise position we want. There is a better way that we construct a sphere which contains all the objects in scene . The objects rotate with the rotation of the sphere, and we call this sphere as arcball. This paper introduces the theory of arcball and how to realize the rotation of 3D graphics of geophysics and geochemistry by using arcball.关键词
