Simulation and rendering methods for real-time marine systems

Abstract

The invention provides a simulation and rendering method of a real-time sea system. The method comprises the steps of: dividing a screen space into a plurality of grids equally, and projecting the screen space to a sea level in a world coordinate system space, and obtaining a surface grid of seawater in the world coordinate system space; obtaining a coordinate deviant of a current grid point relative to the sea level, and obtaining a final coordinate value of the grid point; obtaining a normal value of the current grid point, and realizing a controllable seawater ripple effect; obtaining a normal value of a ripple arranged at the position of the current grid point, obtaining a final normal value of the current grid point, and realizing a sea level ripple effect when it rains; obtaining a seawater color value with a foam effect of the current grid point, obtaining a final color value of the sea level position of the grid point, and realizing a foam effect of a shore dynamic impact; and obtaining an underwater scene color value of the current grid point after etching, obtaining a final color value of the underwater scene of the current grid point, and realizing an underwater dynamic etching effect and an underwater distortion effect with light attenuation.

Description

technical field [0001] The invention relates to a video image processing technology, in particular to a method for simulating and rendering a real-time marine system in a video image. Background technique [0002] In the video image processing of existing 3D games, there are more or less problems in the simulation and rendering of water bodies: the water surface is relatively flat, and the water lines are only simulated by normal lines, and there is basically no real fluctuation in the height direction; The shore cannot produce foam, or some games are still even if there is foam, and will not rush to the shore dynamically with the waves; the water surface will not respond to the weather, such as rainy days, the water surface will not do anything to the raindrops response; the underwater effect is relatively rough, and even some games simply cannot go into the water or even go under the water. [0003] The above-mentioned technical defects make the 3D game not fully reflect ...

Problems solved by technology

[0002] In the video image processing of existing 3D games, there are more or less problems in the simulation and rendering of water bodies: the water surface is relatively flat, and the water lines are only simulated through normal lines, and there is basically no real fluctuation in the height direction; The shore cannot produce foam, or some games are still even if there is foam, and will not rush to the shore dynamically with the waves; the water surface will not respond to the weather, such as rainy days, the water surface will not do anything to the raindrops response; the underwater effect is relatively rough, and even some games simply cannot walk into the water or even go under the water

[0003] The above-mentioned technical defects make the 3D game not fully reflect the real natural scene, and cannot provide players with a good visual experience
