Abstract
The three-dimensional computer graphics claimed today in many fields of the person activity:
producing of computer games, TV, animation, advertise production, visualization systems of out-of-cockpit
environment for transport simulators, CAD systems, scientific visualization, computer tomography etc. Especially
high are requirements for realism of generated images. Realism rising leads to image detail increasing, necessity
of shadows and light sources processing, the account of an environment transparency, generation of various
special effects. Therefore in the field of a computer graphics researches are intensively conducted for the
purpose of development of as much as possible effective models for three-dimensional scenes and fast methods
of realistic image synthesis on their basis. One of the most promising methods is a ray tracing. The method
provides possibility of synthesis of high realistic images; however it demands the large computational cost for the
realization. The cloud synthesis model for a ray tracing is described. The model is directed to a real time graphics
and allows raising realism of the synthesized image. Advantages of proposed model are the ability of working
with cloud on different levels of detail, availability of bounding surfaces inside of cloud structure that allows to
increase efficiency of an image synthesis algorithm, ease of cloud animation. Due to the great flexibility of a cloud
model and high performance of its visualization algorithm these results can be used in real time visualization
systems.
