specific Embodiment approach 1

[0033] Specific implementation mode one: combine figure 1 and figure 2 The HIT-TENA three-dimensional test scene display system based on VR-Vantage in this embodiment specifically includes:

[0034] According to the related theories of HIT-TENA architecture and 3D scene simulation and the demand analysis for 3D scene display software, the HIT-TENA 3D test scene 3D display software can be divided into three major modules: communication and data processing module, and scene-driven simulation elements and 3D model modules such as image 3 shown;

[0035] Communication and data processing modules for acquiring and processing data from HIT-TENA middleware and input devices;

[0036] A 3D model module for constructing 3D scene data and 3D solid models conforming to the VR-Vantage format, and storing the 3D solid models in the form of files in the VR-Vantage 3D scene database; wherein, the 3D scene data includes terrain data ( textures, elevation data) and scene data (time, sunl...

specific Embodiment approach 2

[0045] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the HIT-TENA three-dimensional test scene display method based on VR-Vantage specifically includes:

[0046] Steps for acquiring and processing data from HIT-TENA middleware and input devices;

[0047] A step for constructing 3D scene data and a 3D solid model conforming to the VR-Vantage format, and storing the 3D solid model in the form of a file in the VR-Vantage 3D view database; wherein, the 3D scene data includes terrain data (texture, Elevation data) and scene data (time, sunshine, etc.);

[0048] Steps for driving the received and processed data to drive the 3D solid model to perform real-time update status, update environment special effect rendering, field of view zoom and perspective movement. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0049] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the steps for obtaining and processing data from the HIT-TENA middleware and input device are specifically:

[0050] 1. Receive the data sent by the running platform through the HIT-TENA middleware interface, and transmit the data through the HIT-TENA middleware; among them, the data transmitted through the HIT-TENA middleware specifically includes the motion parameters (position, posture,) and environment of the entity Parameters, etc.; the transmitted data is the position, attitude or environmental parameter data of the entity;

[0051] 2. Receive data sent by input devices (keyboard, mouse, etc.); wherein, the data includes scene scaling and viewpoint movement data;

[0052] 3. Perform data processing, transform the position or attitude data of the entity obtained from the HIT-TENA middleware in step 1 into the position and attitude data of the relevant 3D solid model in the virtual sc...

Abstract

The invention discloses a HIT-TENA three-dimensional test scene display system and a HIT-TENA three-dimensional test scene display method based on VR-VANTAGE. The invention relates to the three-dimensional test scene display system and the three-dimensional test scene display method, which are used to solve a problem of a HIT-TENA system of inability of carrying out the three-dimensional test scene display. The HIT-TENA three-dimensional test scene display system comprises a communication and data processing module, a three-dimensional model module, and a visual simulation driving module. The HIT-TENA three-dimensional test scene display method comprises steps that data is acquired from a HIT-TENA middleware and an input device, and is processed; a three-dimensional solid model is stored in a VR-VINTAGE three-dimensional visual database in a file way; the received and processed data is used to drive the three-dimensional solid model for real-time state update, environment special effect rendering update, view field zooming, and view angle moving. The HIT-TENA three-dimensional test scene display system and the HIT-TENA three-dimensional test scene display method are used for the three-dimensional test scene display field.

Description

technical field [0001] The invention relates to a HIT-TENA three-dimensional test scene display system and method, in particular to a VR-Vantage-based HIT-TENA three-dimensional test scene display system and method. Background technique [0002] The 3D scene display software is widely used. In the military field, it is mainly used in flight visual simulation, naval battlefield visual simulation, tracking radar display simulation, and missile countermeasure simulation to visually and visually display the test process and situation. [0003] At present, domestic commercial 3D scene display software is relatively mature, with powerful functions and convenient use, but the price is relatively expensive. In the development of 3D scene display software, APIs such as Vega Prime and OpenGL are often used for secondary development. They provide standard and open interfaces and are commonly used in the development of visual simulation. VR-Vantage, a 3D scene display software with HLA...
