Problems solved by technology

No matter how large the grid is, there are edges, so the simulated sea level cannot simulate the infinitely vast sea surface
For the sea-sky interface, due to the limitation of the traditional method, there will be an obvious boundary at the sea-sky interface. If the obvious boundary is eliminated, it is necessary to manually find the boundary to eliminate it.

Embodiment Construction

[0031] Please see figure 1 As shown, the present invention provides a method for real-time simulation of sea-sky contact, which includes:

[0032] Step 101, acquire the resolution of the current display.

[0033] Step 102, according to the resolution of the current display, use homogeneous coordinate transformation to generate a homogeneous coordinate space corresponding to all points on the sea level displayed on the current display.

[0034] In a specific embodiment, the step of using homogeneous coordinate transformation to generate a homogeneous coordinate space corresponding to all points on the sea level displayed on the current display includes:

[0035] Establish the coordinate value (x, y) of each pixel in the orthogonal coordinate system;

[0036] Generate a two-dimensional space [x, y] for each pixel; and

[0037] Generates a two-dimensional homogeneous space [x, y, w] where 0<=w<=1.

[0038] The volume of the homogeneous space generated in this way will be rela...

Abstract

The invention provides a sea-sky mergence real-time simulation method, which comprises the following steps of: acquiring the resolution ratio of the current display; generating a homogeneous coordinate space corresponding to all points on the display scene of the current display by using the homogeneous coordinate conversion according to the resolution ratio of the current display; establishing grids in the homogeneous coordinate space; mounting a camera at the current view point, mapping the sea level range and the sky range observed by the camera into the homogeneous coordinate space respectively, and disturbing the grids corresponding to the seawater part which is mapped into the homogeneous coordinate space; mapping the disturbed result onto the scene showed by the camera at the view point; rendering the sea level and sky under the current scene; and displaying the rendered result on the display.

Description

technical field [0001] The invention relates to a method for simulating natural phenomena, in particular to a method for simulating sea level. technical background [0002] In the prior art, the sea level simulation methods basically adopt the grid method, and the grid representation of the sea surface has its own limitations. Due to the size of the grid, the sea level will always have edges. No matter how large the grid is, there are edges, so the simulated sea level cannot simulate the infinitely vast sea surface. For the sea-sky interface, due to the limitations of the traditional method, there will be an obvious boundary at the sea-sky interface. If the obvious boundary is eliminated, it is necessary to manually find the boundary to eliminate it. Contents of the invention [0003] In view of this, the object of the present invention is to provide a method for simulating sea level in real time. It can simulate infinite sea level, and the amount of calculation is cont...
