非聚焦型光场相机成像模拟，光线追迹，成像分析-light field camera

从光场理论出发，实现光场相机1.0的成像过程及计算重聚焦过程模拟，代码完全可见，且尽量简洁明了。(From the light field theory, the imaging process of the light field camera and the simulation of the focusing process are realized. The code is completely visible and concise as far as possible.)

对于光场相机成像系统的模拟以及普通相机二维成像的模拟(Simulation of optical field camera imaging system and Simulation of two dimensional imaging of ordinary camera)
