This is a nice tutorial on differentiable and inverse rendering (one of the Mitsuba authors also gives the tutorial):

Inverse rendering is such a cool idea... solving for the inputs (3D models and materials) to a renderer such that they match real world inputs (photographs) by computing gradients automatically.
