简单的光线追踪引擎在MATLAB从无到有仅仅因为现有的射线追踪，主要针对的是三维计算机图形和不提供适当的访问内部数据（如雷的生命），这是需要计算的差距和/或运动场。(simple ray-tracing engine in Matlab from the scratch just because existing ray-tracers are mainly targeted to 3D computer graphics and don't provide proper access to the internal data (e.g. ray hitpoints), which are needed for the computation of the disparity and/or motion fields.)
