Abstract


Non-regular objects in computer graphics simulation has always played an important role, but also an important research direction in computer graphics. Now researchers at home and abroad through continuous research and practice testing to put forward a variety of non-regular objects simulation modeling method, irregular object simulation modeling method different from computer graphics to mainly divided into the particle system, procedural texture function, physical processes, application of fractal geometry techniques to simulate irregular objects, using the L-system for a finite number of iterations, use bulletin board technology to simulate several methods of irregular objects. Each of the above six modeling method can simulate the very real cloud model, but the shape of the final simulation generated either alone what kind of modeling clouds model itself are randomly generated, or just simulate the specific nature a single cloud, if you want the simulation generates a variety of different types of cloud models, such as at the same time generate combined model Cirrocumulus and stratiform need to use a variety of modeling combining method. Of course, the method of use of the physical process based on the current technology can simultaneously simulation generates a variety of different types of cloud model, able to produce a combination of different types of cloud models in results, but the need to consume a huge amount of time and space, and the present computer technology and the corresponding work platform can not fully satisfy such a requirement. In this article the author through their own practice and research based on computer vision technology applications particle system modeling method to simulate three-dimensional cloud model. Using this method can simulate a variety of different types of clouds exist in nature, so that they can exist in the establishment of the cloud model which. The basic process of this modeling approach is the first application of computer vision technology in their respective three-dimensional contour extracted field shooting pictures of the different types of cloud particle system technology, and then use these three-dimensional contour padding. In the specific operating process, we first extracted in nephogram out different types of two-dimensional shape of the cloud; then the application of computer vision technique clouds contours of these two-dimensional expansion to a three-dimensional space to generate a cloud which exists in the three-dimensional space model; Finally, the method of using the particle system to fill the three-dimensional space. Each particle are filled in this too should have properties such as transparency, color, density and radius, through the adjustment of the different properties of the cloud particles in which the latter part of the repair, and ultimately produce a different kind of cloud simulation effect. In this paper, particle system texture process function method of combining simulation model of natural scenery in the clouds, texture mapping and Billboard technologies to application specific model drawing process, which proposed a number of modeling approach combining the new method of analog irregular objects.
