example 1

[0044] Use Creator / Vega to establish the real-time processing process of the system. After the .flt model file created by Creator is input to the driver software Vega, it becomes a part of the real-time application, such as figure 1 shown. The development process of the system is as follows: first, model all entities in the scene in Creator, load the model into Vega, complete the setting of ADF initial value in the application interface LynX, define windows, channels, observers, motion models, and scenes , objects in the scene, scene moving bodies, environment and environmental effects, light sources, etc., and initialize them, configure the environment required for real-time simulation, compile and save the ADF file, and preview the environment effect. The simulation program is initialized, the Vega application framework is configured, and the three phases of each frame are processed in the real-time application program: Application (application), Cull (interception), and Dra...

[0046] The visual simulation system is mainly composed of two parts: scene modeling and scene driving, such as image 3 shown. The scene modeling part is the premise of visual simulation. We need to use various modeling materials and professional simulation modeling tools to build a model 3D database of each object in the scene according to the complexity requirements of the scene. In the flight simulation modeling, the virtual scene mainly includes the large terrain modeling during the take-off phase, which involves the details of the terrain display, the simulation of the flight scene such as the long-distance ground and cloud and fog effects when pitching, and takes into account the relationship between the aircraft and the external environment. of fitting.

[0047] The scene driving part uses the scene simulation program to generate real-time scenes according to the various scene models established, combined with the real-time input of interactive input devices and the up...

[0049] According to its functions, the system mainly includes a communication module, a real-time visual simulation driver module, and a 3D display output module. The communication module receives the missile flight status data transmitted by the network, and the simulation driver module drives the virtual scene model and the physical model in real time, and determines the switch of the observer's viewpoint. , generation of special effects, update of the position and attitude of the flying body; the three-dimensional display module outputs the three-dimensional dynamic information of the flight and other parameters. The relationship between the main components of the system is as follows: Figure 5 shown.

Abstract

The invention provides an aerocraft view simulation system which consists of a track calculating module which comprises the calculating models of all the tracks and unified interfaces providing communication with other models; a view display module which receives information from a communication module and provides a corresponding display function; the communication module which provides the unified interfaces for obtaining the data of a computer model and simultaneously transmits the relevant data to each view; the communication module is respectively interconnected with the track calculating module and the view display module. Based on the areocraft track pose demonstration view simulation system of a 3D real time dynamic display technology, the invention simulates the flying trace and pose of the areocraft under different environments and intuitively displays the whole running process of the areocraft. Through spaceflight simulation, not only a user is led to more intuitively know the running situation of a spaceflight task, but also the design, validation, demonstration, screening and conformation of a flying scheme can be assisted and finished.

Description

(1) Technical field [0001] The invention relates to a visual simulation technology in the field of simulation, in particular to a visual simulation technology combining flight orbitology, attitude dynamics and computer graphics. (2) Background technology [0002] The earliest aerospace simulation method is physical simulation. Physical simulation can grasp the performance and motion of the aircraft from a macro perspective, but the high cost and complex process requirements, especially the non-repeatability and high risk of physical simulation restrict the application range of physical simulation. [0003] Because simulation technology has many advantages such as safety, economy, controllability, non-destructiveness, allowing multiple repetitions, etc., it is widely used in the military field, especially in the aerospace field. Aerospace simulation is the research work of simulation test and analysis based on physical effect model or mathematical model established according...
