Geometrical Modeling Using Hidden Line Algorithm

ABSTRACT Hidden line algorithms generate realistic scenes by identifying and removing parts of the displayed image or shape that are not visible from a chosen view position. So, in order to achieve highly realistic view, Hidden Line Package (HLP) has been developed to draw many shapes of three-dimensional object using Depth-Sort hidden line algorithm. This program uses one of the projection methods, either the perspective or the parallel method, to draw many types of three-dimensional shapes and then apply any transformation techniques (scaling, rotation, or translation), in addition, the program draws the shapes in transparent or solid modes. The resultant shape can be stored as an image file of BMP extension. The software has been written by the authors using Microsoft Visual Basic 6.0. . HLP . . BMP . 6.0.
