[0025] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
[0026] The main idea of the technical solution of the present invention is to use the 3D rendering technology in WPF to realize the three-dimensional pie chart. First, describe the basis for realizing the 3D interface. The basic idea of generating 3D graphics is to obtain a three-dimensional model (Model) of an object. Since the screen is only two-dimensional, a camera (Camera) for taking pictures of objects is defined. The photos taken are actually the projection of the object onto a flat surface. This projection is rendered into a bitmap by the 3D rendering engine. The engine calculates all The amount of light reflected by the light source on the projection surface of the object in the 3D space determines the color of each pixel in the bitmap.
[0027] Each surface of an object has a material...
