As someone coming from the physics side and not so much from the Computer graphics side of physically based rendering, I have high hopes for differentiable rendering as a general tool to extract knowledge from light-based measurements. Most differentiable renderers stop at the object surface, but differentiable volumetric light transport is what would allow us to use the renderer to optimise a measurement device or for medical diagnostics or just to estimate the optical properties of a material (that is absorption and scattering coefficent and scattering phase function), which is a pretty hard problem in itself. From a quick look, Mitsuba 3 seems to have everything in place to be used in such a setting and I'm really excited to see some use cases outside of Computer graphics.
