Vizualizátor komplexních modelů tvořených pomocí NURBS

Abstract

This thesis deals with the rendering of complex models represented by NURBS surfaces. For this rendering OpenGL and its superstructure GLU 1.3 are used. The thesis is divided into theoretical and practical part. The theoretical part discusses important information about NURBS and their use in OpenGL, using the add-on library GLU. Then STEP file, which is used as input format for the application is described. In the practical part final application is discussed. This section describes in detail the process from receiving the file to its rendering in OpenGL. Fragments of an application, which file passes, can be split into three parts: parsing part, where we get the necessary data for creating NURBS, computational part, where all the necessary calculations are performed and rendering part, which is responsible for a meaningful representation of the obtained data. The main objective of this thesis is to create an application capable of calculating and rendering of complex scenes stored in files such as STEP, or CBA.
