Abstract
The use of three dimensional computer graphics and visualization techniques is becoming more and more popular, because these techniques visualize more realistic object models than graphic based object models. However, in most application of 3D modeling and visualization, large and complex 3D models data are required. The basic data source of 3D modeling of regular or irregular surfaced objects are known (or calculated) point coordinates. Obtaining 3D model of the irregular surfaced objects need plenty of points to represent the surface exactly. These points can be easily obtained both traditionnal methods and from the measurement of the photographs. the production of 3D object in cloud points dependind on the sampling rate and taking many captures. In this case, an object of face-shaped clay was used and a 3D object is performed with (5563) 3D points with sampling rate (1 mm). The smaller sampling rate results in longer processing and more points. This case could be beneficial in documentation of cultural and historical heritage in a digital library in observing the variation with time.
