specific Embodiment approach 1

[0028] 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:

[0029] 1. Build a human-computer interaction platform;

[0030] 2. Three-dimensional virtual modeling and display of submarine-based missiles' water exit process: use MultigenCreator and 3DSMAX to establish three-dimensional models of submarines, missiles and surface ships, and establish virtual simulation scenes of ocean, sky, islands and submarine terrain;

[0031] 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 simulat...

specific Embodiment approach 2

[0036] 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, using single document multi-view technology, FluentUI technology, and GDI technology to design the human-computer interaction interface interface, 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

[0037] 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.

The method includes the following contents: 1. Building a human-computer interaction platform; Modeling and display; 3. Particle system-based visual modeling of submarine-based missiles exiting water; 4. Visual modeling of submarine-based missiles exiting cavitation bubbles based on coloring language; 5. Dynamic display of ocean depth scales; 6. Process of submarine-based missiles exiting water 7. Visualization of the key parameters of the submarine-based missile's water exit process. The invention has the advantages of being safe, economical, controllable, non-destructive, allowing multiple repetitions, and the like. The invention can be applied to the technical field of computer simulation method.

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...
