I am wondering if there is any current research/implementation to this problem:

Say given 2 images, one with an object lighted with an (assumingly) uniform lighting, and another image, with the same object, illuminated with a fixed, single light source. Is there a relatively simple way to say, given a 3rd image, with the same object, but from another perspective, to generate a similar lighting?

In order words, is there a way to remodify the 3rd image, such that it looks like how the object would look like under similar lighting conditions as in the 2nd image? Without going through the entire process of building a 3d physics simulation.

Of course, assuming that the objects are purely solid, and ignoring things like transparency and different albedos of the different portion of the object within the images. And that we also have the perspective relations between each individual image.

Somethink like this?

Not exactly. What i am looking for is more of like to simulate how an image of an object would look like under different lighting conditions; as opposed to having different lighting conditions as inputs to model an object.

something like this but it is not image processing
