Paper Abstract

A new method for automatically reconstructing a three dimensional object from a serial cross section is presented in this paper. The method combines the technical chaining contour and the sampling method to construct an object. In the proposed method the initial description of the object is formed by a serial continuous contour. First we sample each cross section to determine the nods that constitute the vertices of the triangles used for the reconstruction, then we determine the tangent in these nods and we assign to each one of them a code depending on the tangent direction. For triangulation there is nothing left to do but collect the nods of two adjacent contours the code of which is identical.
