Моделирование и визуализация сложных поверхностей на основе скалярных функций возмущения

Abstract

The problem of real-time photorealistic imaging of complex surfaces such as digital terrain is discussed. New technique for complex surfaces by scalar perturbation functions without its approximation by polygons is considered. A recursive algorithm for object space subdivision with masking of invisible surfaces and an effective technique of projective transformation for perspective imaging are proposed. The possibility to visualize photo-realistic terrain is shown. Examples of images obtained by modeling the work of the algorithm with elevation map of defining the digital terrain are presented
