  • Monte Carlo integration TODO：好好学习一下蒙特卡洛的数学代码方法
    • PDF: Probability Density Function

Finite Differences doesn’t work

  • By Appling Antialiasing Inverse rendering more robust

    Anti-aliasing makes 0-1 Binary value -> Continuous, which suits differentiate

  • Inverse rendering(in CG) == Analysis by synthesis(in CV)

  • Global minima – ambiguity

  • How to implement neural network based learned initializations？

  • Leibniz Integral Rule***(How to prove? How to apply?)***

    • Reynolds transport theorem

  • Aera sampling

  • Redner, Mitsuba
