Embodiment Construction

[0039] The detailed structure of the present invention, application principle, function and effect, refer to the appended figure 1 -9, described through the following embodiments.

[0040] General-purpose simulated flight engine of the present invention comprises the following steps:

[0041] a) Using the PQT algorithm, according to the four display effect levels of high, medium, low, and extremely low, use the number of triangles respectively 26N, 24N, 22N, and N to construct the earth’s surface partition model, and match the positioning coordinate data corresponding to each triangle area , and then input the aforementioned partition model and coordinate data into the PQT earth model algorithm module, where N is the number of triangles of random numbers, which is the number of triangles randomly generated by the computer according to the content required to be drawn, which is included in the open directX SDK The function operation is determined;

[0042] b) Input data thro...

Abstract

The invention discloses a general flight simulation engine, relates to the technical field of electronics and aims to solve the technical problems that the conventional flight simulation engine does not have generality, cannot meet the requirement of global flight simulation, only can perform simulation in a single field or a single subject and the like. The general flight simulation engine consists of a PQT (preamble quality threshold) earth model algorithm module, a physical weather simulation module, a WGS (world geodetic system) dynamic positioning module, a dynamic illumination module, a comprehensive processing data superposing module, a landscape module, a multilayer detail module and a graphics rendering module.

Description

technical field [0001] The invention relates to the technical field of avionics, in particular to a visual system for simulating flight. Background technique [0002] Existing flight simulation engines all perform scene simulation for a single aircraft type and are not universal. [0003] See attached figure 2 As shown, the existing simulated flight visual system uses regional simulation, that is, it only models a specific area, so there is a flight boundary, and it is not possible to conduct a large-scale simulated flight, nor can it choose to take off and land at an airport outside the set area. . [0004] The existing simulation system does not include the LOD algorithm, and cannot realize large-scale and high-precision landscape loading. [0005] BJ54 and Xi'an 80 coordinate systems are mostly used in the existing domestic simulation flight scenes, which cannot match the international mainstream WGS84 coordinate system in terms of terrain data, and coordinate system ...
