摘要
文中剖析了Ogre渲染引擎的工作原理,描述了基于GPU的后处理技术,利用Ogre渲染引擎通过GPU实现了二维快速傅里叶变换,添加了探测器成像系统调制传递函数(MTF),实现了系统线性噪声和随机噪声的添加,模拟了实时三维红外场景中的探测器效应。
This paper analyzes the working process of Ogre rendering engine and describes the principle of Post-Processing technique in GPU. Then MTF and noise in the infrared detector are implemented with the 2D FFT method in GPU in order to simulate infrared detector effect in Ogre rendering engine in real time.
