| Abstract [eng] |
Variational subdivision schemes as distinct from classical (Catmull – Clark, Loop, Doo-Sabin) in every subdivision step allows to change the subdivision rule. Therefore we are able to get wider set of smooth surfaces. We made a software that using the entered parameter γ constructs variational subdivision mask with trigonometric functions and applies it to surfaces. Software is able to show surface in 3D space with move, rotate and zoom abilities. Software also can export surfaces to VRML file format. Subdividing surfaces by our software we faced with border and extraordinary vertex problems. We suggested and realized two solving methods for both problems. Our software is able to control the surface's smoothness and sharpness in all subdivision steps. Using variational subdivision schemes and rotation methods, we can generate a wide set of surfaces witch also includes classical CAD figures (sphere, cylinder). |
