大規(guī)模水的動畫和實時渲染技術
[Abstract]:In the field of computer graphics, the simulation of natural scenery is an important research subject, it has a wide range of applications in virtual reality, computer games, film and television, advertising, visual simulation and other fields. In the simulation of natural scenery, water simulation is an important part, because the lack of water simulation will significantly affect the reality and coordination of the natural scene. However, water is irregular and not repeated in time and space, and there are special requirements for water rendering. Therefore, water simulation has always been a very challenging topic. In this paper, through the reference of a large number of domestic and foreign research results, summarized and innovative, the real-time rendering of large-scale water scene is deeply analyzed and studied, and a new rendering method with high rendering efficiency and visual effect is proposed. In this paper, based on the FFT method of ocean statistical model, not only the vertex 3D data for the deformation of the water surface grid is calculated, but also the surface normal vector for the surface illumination calculation is calculated. The calculated height field data are laid across the grid in a large area to simulate the wave effect of large scale water surface. The continuous animation and real-time rendering effect are realized, and the reality of the water surface scene is increased. In order to better foil the large-scale water surface, this paper adds the illumination effect between the water surface and the surrounding bad environment, the sun light, the water object respectively, the visual effect is quite obvious. Finally, according to the water surface modeling method mentioned above, according to the object-oriented design principle, this paper designs and implements a large-scale real-time rendering system of water surface using Visual C and OpenGL. The generated water surface is adjusted by adjusting the values of the parameters.
