Rekonštrukcie povrchov z neparalelných rezov s použitím interpolačných metód
Ilavský, Ján ; Felkel, Petr (advisor) ; Kolingerová, Ivana (referee)
Reconstruction from non-parallel cross-sections is not very well studied problem. This work provides overview of methods used to solve it. Step by step there are described all the algorithms from obtaining input data to visualize reconstructed surface. Main focus is put on methods which create distance function interpolating data from cross-sections. The closest point, average normal and disc-guided interpolation are described in details. Out of visualization techniques there are mentioned straight methods and defined in detail marching cubes, marching tetrahedra and regularized marching tetrahedra. All this methods are implemented and used in windows application to compare their results in reconstruction of models saved in ASE format. First of all this model is cut into several cross-sections inside this application. These are used to create distance function using one of the interpolation methods. At the end, distance function is visualized. To compare results, there is used volume computing algorithm based on ray-casting and subjective user opinion based on graphical output.
