Embodiment Construction

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] figure 2 It is a processing schematic diagram of the processing method of the water body grid in the virtual reality three-dimensional water body rendering of the present invention. see figure 2 , the method mainly includes:

[0041] Step 201, according to the height data of each vertex in the water body grid and the height data of each vertex in the ground grid of the same cell, determine the height relationship between the water body grid and the ground grid.

[0042] In the present invention, the water body grid and the ground grid are cells that are synchronously divided in the virtual reality scene. That is to say, in the virtual reality scene, in the specified plane, for example, the grid with the same length and width is divided by the horizontal plane here, and the cells of each grid extend vertically up and down, ...

Abstract

The invention discloses a water grid processing method for three-dimensional water rendering in virtual reality. The method comprises the following steps: the height relation between each water grid and a ground grid is determined according to height data of vertexes of the water grid and height data of vertexes of the ground grid of the same cell; each water grid is processed as follows: when the water grid is lower than the ground grid, the water grid is deleted; when the water grid intersects with the ground grid, the part, higher than the ground grid, of the water grid is reserved, and the part, lower than the ground grid, of the water grid is deleted; when the water grid is higher than the ground grid, the water grid is reserved; the water depth of each water grid higher than the ground grid is computed, and the water grids with water depths higher than preset water depth are combined in a power series manner. With adoption of the method, the usage quantity of computing resources and the invalid rendering quantity can be reduced, and the rendering efficiency is increased.

Description

technical field [0001] The present application relates to the technical field of virtual reality, in particular to a method for processing water body grids in virtual reality three-dimensional water body rendering. Background technique [0002] Virtual reality technology is a computer simulation system that can create and experience a virtual world. This technology uses a computer to generate a simulated environment. The user is immersed in the environment. [0003] At present, virtual reality technology is widely used in application scenarios such as 3D games and simulation exercises. In virtual reality technology, it is often necessary to shape and render the virtual environment to make the virtual environment as realistic as possible. [0004] In the virtual environment, the three-dimensional water body is an indispensable part of the scene. The rendering of 3D water bodies is inseparable from water body grid data. When rendering the water body, the water surface is r...
