Semi-globalization of stochastic spectral synthesis

This paper describes a new approach to stochastic modeling for natural objects that provides a unified model for describing terrains, clouds, sea waves and many other shapes. The geometrical data of the model can be created or modified without undue computational time, simply by specifying several parameters. In addition, these parameters have intuitive meanings, which make it easy to control the model's geometry. Then the models for different natural objects can be effectively combined through some functional operations, which makes the method more flexible for acquiring realistic images of complex three-dimensional scenes.
