发明名称 METHOD AND SYSTEM FOR DISPLAYING A THREE-DIMENSIONAL OBJECT
摘要 This disclosure describes a method for displaying a three-dimensional object wherein a three-dimensional space is virtually divided into a plurality of elements arranged according to predetermined directions, each of said elements being virtually divided into an equal number of sub-elements, and the positional relationship of sub-elements in one element is common to all the elements. Graphics data of one polygon are generated in each sub-element, and a 3D object is displayed on the basis of the generated graphics data of polygons. The method includes the steps of providing data on the position of a view point and a reference point, and generating data for a view vector connecting the view point and the reference point; determining the depth order of said elements on the basis of the view vector data and the vector data on the arrangement directions of said elements; determining the depth order of sub-elements in one element, which is commonly applicable to all the elements, on the basis of data on the position of the sub-elements contained in the element and the view point; and transferring the generated graphics data of polygons to a display apparatus in order of the depth of said elements and of sub-elements in one element.
