Abstract

The invention belongs to a comprehensive simulation method for a realistic cloud layer in simulation techniques, which comprises the following steps: setting a sky background and an airspace cell grid; distributing clouds initially; establishing a virtual cloud layer plane model; setting a distance threshold between a view point and the cloud, and various hybrid parameters of clouds and an image; and processing comprehensively. The comprehensive simulation method for the realistic cloud layer comprehensively simulates the cloud layer by a plurality of technical measures and adopts different methods to process far and near cloudscapes, so that the sense of reality of the simulated cloud layer and the speed and the instantaneity of the simulation are improved effectively, and particularly has remarkable advantage of simulation on a large-scale cloud layer and a complex scene and high simulation speed. Thus, the comprehensive simulation method for the realistic cloud layer has the characteristics of achieving effect of a three-dimensional panoramic cloud layer by simulating a two-dimensional plane, having simplicity and reliability, offering strong sense of reality of simulated cloud layers, having high simulation efficiency, strong instantaneity and low requirement on the configurations of software and hardware, and the like; and the method overcomes the defects of sheet sense, poor sense of reality and the like in the conventional technology for simulating a three-dimensional cloud layer by the two-dimensional plane.

Description

technical field [0001] The invention relates to the field of computer visual simulation technology, in particular to a rapid simulation method for displaying realistic cloud layers through comprehensive processing using cellular automata, texture mapping, bulletin board technology, etc. Simulation demonstration of moving target through cloud vision. Background technique [0002] Real-time rendering of realistic clouds is a challenging task in visual simulation. At present, cloud simulation can be divided into methods based on individual growth and methods based on physical processes. Methods based on individual growth include fractal geometry, process texture function, cellular automata, and particle systems, which mainly use human visual morphological features to obtain the visual shape of clouds without simulating the real physical process of cloud generation or dissipation. The speed is fast, which is more suitable for the needs of the current common hardware platform, ...
