Problems solved by technology

[0006] The computer implementation of ocean waves requires a large amount of data calculations to generate, but due to the large amount of sea surface simulation data and the large amount of calculations, it is difficult for ordinary computers to realistically complete the real-time simulation of the sea surface in large scenes, and the real-time calculation is the bottleneck of sea surface simulation

Embodiment Construction

[0045] The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

[0046] Ocean waves have rich detailed features and dynamic characteristics. Due to the irregular nature of ocean waves, how to describe enough details with the least amount of space-time overhead has become the main task of simulating ocean waves. In order to achieve real-time performance, a 3D application program needs 15 frames / s. At such a refresh rate, it means that a real-time 3D application program needs to update hundreds of millions of pixels per second, requiring the CPU to do considerable work for each The display is updated with a new image. Conventional CPU-based processing technology can no longer meet the application needs, so it is necessary to make full use of the working ability of the computer graphics processor technology GPU to share the burden of the CPU and improve real-time performance. The framework of the wave modeli...

Abstract

The invention discloses a dynamic interpolation method and a sea surface scene generation method. The dynamic interpolation method comprises setting sea surface generation point coordinates to be a function related with time and calculating the number of dynamic interpolation points required to be added to any point place and corresponding coordinates of each dynamic interpolation point. The sea surface scene generation method adopts a new dynamic interpolation method--multiple dynamic nonuniform interpolation, and one or more points can be added dynamically according to the specific value of height difference, so that image discontinuous phenomena of an image due to unpredictability and uncontrollability of random parameters can be effectively reduced, simulation effect can be improved, and meanwhile, since trigonometric function calculation of a sea wave fluctuation equation is reduced, the method also plays a good effect on improving the simulation real-time performance.

Description

technical field [0001] The invention relates to a dynamic interpolation method and a sea surface scene generation method. Background technique [0002] The research of ocean waves is of great value in the fields of modern hydraulics, fluid mechanics, wave science, computer graphics, virtual reality applications, and radar echo simulation. As an important part of ocean wave research, ocean wave simulation technology is used in military field environment simulation research on sea battlefields, naval tactical missile flight control experiments, sea surface echo simulation, radar imaging simulation research, etc., for the simulation development of combat platforms and the development of weapon systems. Lay the groundwork. [0003] At present, there are many types of modeling methods for ocean waves, but most modeling methods only address certain specific application requirements, which makes the emphases of the models different. For example, in applications such as 3D online ...
