Problems solved by technology

However, the common problem of the above-mentioned scheme is that the speed is slow; the above-mentioned method will not cause any problems for the application with a small number of grid points, and can guarantee the corresponding real-time performance, but for the application of a large number of grid points, the triangular grid processing If the time is too long, it will be difficult for users to accept
Moreover, the grids triangulated by some algorithms will overlap and overlap, which will cause flickering problems when rendering in the later stage.
[0003] In addition to the above problems, some algorithms will disrupt the original order of the grid points after triangulation processing, which also makes it take a lot of time to find the attributes corresponding to the grid points (such as temperature, water depth, etc.), making The problem of slow speed is more serious; therefore, it is a technical problem to be solved urgently by those skilled in the art to design a fast model construction for applications with a large number of grid points.

Abstract

The embodiment of the present invention relates to the field of three-dimensional visualization technology, and discloses a method for quickly constructing a display model, including: acquiring discrete grid point data; performing coordinate conversion on the grid point data to transform the coordinate data in three directions Coordinate points are converted into latitude and longitude data; triangular grid processing is performed on the latitude and longitude data to obtain a corresponding grid display model; real-time rendering and display is performed on the grid display model. The rapid construction processing method of the display model in the embodiment of the present invention converts the three-dimensional grid points in the three-dimensional space into longitude and latitude data, so that the subsequent triangular conversion does not need to consider the height of the triangular grid processing method; During the triangulation process, by reducing the data of one dimension, the processing speed of the model triangulation is greatly improved.
