Problems solved by technology

[0002] The traditional radar simulation method has relatively abstract analysis methods. For complicated mathematical formulas and a large amount of data, it is difficult for ordinary trainers and decision makers to make quick and accurate judgments except for professionals who understand the real situation.

Embodiment Construction

[0046] 1) Under the Windows7 operating system, use VisualStudio2010 to establish an OpenGL simulation system framework based on MFC single document, the following steps are the operation steps to use VisualStudio2010 to establish the simulation system framework:

[0047] 1. Use "MFC Application" to select "Application Type: Single Document" to create a project based on MFC single document;

[0048] 2. Add OpenGL library files and header files to the created project to complete the initialization settings;

[0049] 3. Call OpenGL related commands to draw graphics;

[0050] 4. Exit the OpenGL drawing window, and release the OpenGL drawing context and Windows device context at the same time.

[0051] 2) By reading the external image file, the OpenGL texture map method is used to draw the object module (tree, mountain, etc.), the sky module, the ocean module and the light module to construct the environment system. Among them, in the ocean module, in order to get close to the re...

Abstract

The invention belongs to the technical field of civil ship navigation, and discloses a three-dimensional motion scene based simulation system design method. The method comprises: firstly, establishing an MFC single document based OpenGL simulation system framework; secondly, drawing an environmental system with an OpenGL texture mapping method; thirdly, establishing a coordinate system; fourthly, loading three-dimensional models of ship and aircraft targets, generated by utilizing a computer aided design technology, into a program framework; fifthly, reading external driving data through real-time communication to realize target state updating; sixthly, establishing a perspective conversion system, and realizing different observation effects through keyboard interaction; and finally, realizing a smooth animation by utilizing an OpenGL double-buffer technology, and displaying target information through a data display system. According to the method, state images of the ship and aircraft targets in set water area and sky environment under given motion parameters can be formed, a shared audio-visual environment is created for training personnel, and a result is more realistic and more credible.

Description

technical field [0001] The invention belongs to the field of three-dimensional motion visual technology, which utilizes signal processing, computer-aided design technology, visual simulation technology and computer simulation technology to realize the three-dimensional simulation of various ships and aircraft targets in different wind directions, wind speed levels and different operating states. Visual animation, the simulated visual animation effect can intuitively and truly reflect the influence of set simulation parameters on the target motion state of ships and aircrafts. The invention relates to a design and implementation method of a simulation system based on three-dimensional motion visuals. Background technique [0002] The traditional radar simulation method has relatively abstract analysis methods. For complicated mathematical formulas and a large amount of data, it is difficult for ordinary trainers and decision makers to make quick and accurate judgments except f...
