改进的实时海浪网格模型

基于深水中的长峰波波浪模型,给出了视点相关的梯形海面网格自适应模型,能快速逼真的实时生成航海仿真系统中的多通道海浪。本算法只对每个通道可见部分的网格海面进行计算,满足屏幕图像各点的分辨率,在保证较好的图像质量的同时提高了绘制效率。可以通过控制网格的疏密和波浪序列的数目,灵活的控制绘图的质量和计算时间上的花费,满足不同配置的仿真应用。

Improved Real-time Ocean Wave Mesh Model

We present an eye-point related adaptive ocean surface mesh model for real-time simulating irregular long crest waves in navigation simulation system. The method restricts computations to the visible part of the ocean surface in each view channel, the generated mesh density transition is continuous and an adequate resolution being maintained everywhere in the computed ocean image. The method provides a flexible control of the quality/cost ratio by adjusting the mesh density and the number of simulated unit waves. The method allows the user to move over an unbounded ocean following the own-ship, and immersed in a real-time updated photo-realistic ocean environment.
