specific Embodiment approach 1

[0027] Specific embodiment one: the three-dimensional dynamic simulation method of the submarine-launched missile water process of the present embodiment, described method is to realize based on CPU-GPU heterogeneous multi-threaded development environment, it is characterized in that described method comprises the following content:

[0028] 1. Build a human-computer interaction platform;

[0029] 2. Three-dimensional virtual modeling and display of submarine-based missiles' water exit process: use Multigen Creator and 3DS MAX to establish three-dimensional models of submarines, missiles and surface ships, and establish virtual simulation scenes of ocean, sky, islands and submarine terrain;

[0030] 3. Visual modeling of submarine-based missile water outlet based on particle system: use particle system modeling method to establish ship traveling wave, missile tail flame, magazine opening bubble, missile outlet water vapor, missile water vapor particle special effects, and simul...

specific Embodiment approach 2

[0035] Specific embodiment two: the difference between this embodiment and specific embodiment one is that the human-computer interaction platform described in step one is built under the environment of VC++ and OSG three-dimensional rendering engine, and VC++ is used to build the system platform and interface. Utilizing the technical characteristics of the MFC platform, the human-computer interaction interface is designed using single-document multi-view technology, Fluent UI technology, and GDI technology. The OSG 3D rendering engine provides virtual reality technology to realize the 3D virtual simulation of the submarine-based missile's water exit process. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0036] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that the 3D model described in step 2 is stored in a binary file in IVE format. Others are the same as in the first or second embodiment.

Abstract

The invention discloses a three-dimensional dynamic simulation method for a water outlet process of submarine-launched missiles, and relates to a three-dimensional dynamic simulation method. The method aims to solve the problems of complex testing equipment, high testing cost and weak repeatability in the ground simulation tests. The three-dimensional dynamic simulation method for the water outlet process of the submarine-launched missiles is realized based on CPU-GPU isomerous multithreading development environment, and comprises the following contents: (1) a human-computer interaction platform is built; (2) three-dimensional virtual modeling and displaying for the water outlet process of the submarine-launched missiles are implemented; (3) visualization modeling for the water outlet process of the submarine-launched missiles is implemented based on a particle system; (4) visualization modeling for drum vacuole of the submarine-launched missiles is implemented based on coloring language; (5) sea depth staffs are dynamically displayed; (6) multi-view interactive three-dimensional navigation for the water outlet process of the submarine-launched missiles is implemented; (7) key parameters for the water outlet process of the submarine-launched missiles are visualized. The three-dimensional dynamic simulation method has the advantages of safety, economy, controllability, no damage and recycling property, and can be applied in the technical field of computer simulation methods.

Description

technical field [0001] The invention relates to a three-dimensional dynamic simulation method, which belongs to the technical field of computer simulation simulation methods. Background technique [0002] Modern warfare pays more and more attention to precise strikes against the enemy and stealth protection for one's own side. Submarine-launched missiles combine the characteristics of both submarines and missiles. They have the advantages of long range, high power, high hit accuracy, strong survivability, and strong defense penetration capabilities. Strategic deterrence and second-strike capabilities. [0003] The development of submarine-launched missiles began in the 1950s. However, due to the difficulty of underwater launch technology for submarine-launched missiles, only a few countries such as Russia, the United States, and France have relatively mature submarine-launched missile launch technologies. . my country began to develop submarine-launched missiles in the mi...
