<p style="margin: 0px; font-family: Helvetica;">Report 35 p., 3 chapters, 16 fig., 1 table, 12 sources, 5 appendicies</p><p style="margin: 0px; font-family: Helvetica;">&nbsp;</p><p style="margin: 0px; font-family: Helvetica;">wireframe model, pseudo-wireframe model, reconstruction of pseudo-wireframe model, reconstruction of wireframe model, reconstruction of framed 3D objects from 2D projections</p><p style="margin: 0px; font-family: Helvetica; min-height: 14px;">&nbsp;</p><p style="margin: 0px; font-family: Helvetica;">The development target is an application for 3D Framed Objects Reconstruction from 2D Projections.</p><p style="margin: 0px; font-family: Helvetica;">&nbsp;</p><p style="margin: 0px; font-family: Helvetica;">The development objective is the development of an application that receives three orthographic projections as an input and creates and three-dimentional wireframe model as an output.</p><p style="margin: 0px; font-family: Helvetica;">&nbsp;</p><p style="margin: 0px; font-family: Helvetica;">During the course of work the analysis of existing approaches to the reconstruction of 3D objects: the boundary representation and constructive solid geometry, - was provided. Several algorithms for reconstruction of three-dimensional models were also analyzed.</p><p style="margin: 0px; font-family: Helvetica;">&nbsp;</p><p style="margin: 0px; font-family: Helvetica;">As a result, an application that allows to open three files of orthographic projections in one of the major CAD image-storage formats - DXF, and to reconstruct the 3D pseudo-wireframe model of an object. The user can interact with the resulting model (rotate, scale). Additionally, the user can remove edges to obtain the required wireframe model.</p><p style="margin: 0px; font-family: Helvetica; min-height: 14px;">&nbsp;</p><p style="margin: 0px; font-family: Helvetica;">The main difference of the application from its analogues is the ease of use and the support of the operating system OS X.</p><p style="margin: 0px; font-family: Helvetica; min-height: 14px;">&nbsp;</p><p style="margin: 0px; font-family: Helvetica;">The program can be used in the study of engineering and computer graphics.</p><p style="margin: 0px; font-family: Helvetica; min-height: 14px;">&nbsp;</p><p style="margin: 0px; font-family: Helvetica;">In the future it is planned to add the feature to reconstruct solid objects from 2D projections.</p>
