Abstract

The invention provides a visual special effect simulation method based on GPU parallel computing. GPU parallel computing technology is applied to real-time simulation operation and various large-scaleterrain simulation operation of tracks, smoke, fire and light and the like. An optimized file / memory mapping mode is adopted to carry out read-write access on large-data-volume image data; and the analog simulation state of the simulation special effect is calculated in real time according to the analog parameters, so that the storage and access efficiency of a large-data-volume image file, the internal concurrent capability of a multi-element display scheduling function in a global three-dimensional environment and the concurrent processing capability among the functions are improved, and athree-dimensional display scheduling processing algorithm and codes are optimized.

Description

technical field [0001] The invention belongs to the technical field of visual simulation, and relates to a visual special effect simulation method based on GPU parallel computing, which creates efficient scheduling and display drawing directly applied to data visualization in virtual reality visual simulation. Background technique [0002] The 3D visual simulation system often needs to perform real-time simulation and simulation of some special effects in the environment, such as explosions, flames, smoke, dust, etc., to construct a highly realistic virtual environment situation. Environmental effects are driven by real-time data and simulation data, corresponding to specific models, with exact time trigger points and spatial positions. Drivers to display these environmental effects often consume a lot of computer resources, especially the CPU. Traditional 3D special effects technology is often implemented in a non-real-time manner, that is, using 3D special effect processi...
