Geometric modeling plays an important role in design and constructionprocesses. Many researchers have analyzed and examined their ideas in geometric models.Geometric modeling plays a major role in industrial and engineering advances. In the pastyears, great measures have been taken in the field of modeling the human body organs.Therefore, CT-Scan images are obtained from taking photos by digital cameras and they areconverted into digital photos. The use of a mid-range filter increases the image quality; and thetomography is performed using the histogram and thresholding methods. A 3D sample can beobtained by putting together these tomographs. A 3D can be also obtained by separating 2Dimage vectors and placing them rotationally in a 3D-axis direction. Another way is to get cloudof points from organs of the human body. In this method, cloud of points of a bone are takenusing a 3D coordinate measuring machines or 3D scanners, and it is converted into a 3D modelin a special software. Due to the advancement of sciences, the simulation of surgery by the CTScan data makes treatment faster and easier.
