我们提出了一个相机透镜模拟模型，能够产生先进的摄影现象，在一般的光谱蒙特卡罗图像渲染系统。我们的方法结合了几何衍射理论，光学工程和玻璃科学的见解。我们展示了如何有效地模拟所有五个单色像差，球面和彗差，散光，场曲和失真。我们还考虑色差，横向颜色和孔径衍射。菲涅耳反射的列入产生正确的透镜耀斑，我们提出了一个优化的采样方法的路径生成。
We present a camera lens simulation model capable of producing advanced photographic phenomena in a general spectral Monte Carlo image rendering system. Our approach incorporates insights from geometrical diffraction theory, from optical engineering and from glass science. We show how to efficiently simulate all five monochromatic aberrations, spherical and coma aberration, astigmatism, field curvature and distortion. We also consider chromatic aberration, lateral colour and aperture diffraction. The inclusion of Fresnel reflection generates correct lens flares and we present an optimized sampling method for path generation.
