Inverse Rendering of Refractive Media |
This page shows my latest (and the best) results that
I have obtained regarding inverse caustics.
I propose here a new technique to compute the parameters of a refractive
medium, knowing the 3D geometrical model of the scene, the camera properties,
the positions and intensities of the light sources and a single image of
the real scene. Right now, this technique has only be tested on computed
graphics images.
If you want know some details about the technique that I have developed,
please email me.
The first "inversed caustic" (left: original image, right: reconstructed):
An image that really was a nightmare to inverse (watch the combination of caustics on the painting: the blue caustic is a combination of the violet object and the green/blue one; for now no chromatic dispersion for inverse rendering):
One of my favourite reconstruction and it is much tougher than it looks (the texture for the previous and the following original images are known in advance):
When I was tired about inversing the scene, I was augmented
it ! Look at the following image (reconstructed media in a new environment):
One of the thing that you can do if you get bored reading this webpage is asking me for a Toronto famous bottle of wine "DGP Cuvee 2002" and just drink it ! One day, maybe, I will inverse it (I better do that soon because it is not even half full now...)
Some animations that I have computed and that were very
useful to understand the refraction phenomenum...
The first animation shows a simple sphere with a refractive index moving
from 1.0 to 3.99 (step:0.005).

The second animation shows a glass containing a liquid with a refractive
index varying from 1.0 to 3.99 (step:0.005). Note that for two very different
refractive indices (liquid), the part refracted throught the glass and the
liquid look sometimes the same but always produces very different caustics.

The third animation animation shows a glass with a refractive index varying
from 1.0 to 2.9 (step:0.05). For evey index, the refractive index of the
liquid varies from 1.0 to 3.99 (step:0.05).
