| Abstract: |
| In computer graphics, ray-tracing is a high realistic rendering algorithm. Traditional rendering algorithms ignore polarization effect, while related studies show that polarization makes a substantial difference on rendering results. Polarization ray-tracing, at the core of predictive rendering, not only can provide high-realistic rendering image but also is applied in many other tasks such as navigation. Up to now, there is no related work around this topic in China. Under the framework of predictive rendering, this article provides an analysis and summary on key points and future works of polarization rendering following the procedure of polarization ray-tracing algorithm. |
