Методи та засоби підвищення реалістичності та продуктивності текстурування у системах комп’ютерної графіки

Abstract

In the thesis the theory of rendering of three-dimensional scenes was supplemented, which allowed to solve the problem of improving the performance of image formation and their realism in computer graphics systems using new methods and tools for texture overlay, filtering and simulation of surface irregularities. Three-dimensional computer graphics provide the highest realism of visual reproduction of objects and processes of the real world. Since the performance of graphics tools provides the ability to display highly realistic three-dimensional objects, the requirements for the level of complexity of models and the accuracy of reflection of highly detailed surfaces are also constantly growing. The formation of dynamic graphic images in real time and in interactive mode imposes stringent performance requirements of texture mapping. The use of simple techniques blending textures is not acceptable to produce realistic looking images. Therefore, there is a need to develop new methods and means of texturing in order to reduce the complexity of realistic reproduction of graphic scenes. On the basis of the theoretical propositions, models, analytical dependences, results of the experimental analysis obtained in the thesis, the author proposes algorithms and software tools for texture mapping in the systems of highly realistic rendering of three-dimensional images. The obtained characteristics and parameters of the developed tools confirm the correctness of scientific provisions and the adequacy of the proposed models.
