We took several reference images using a diginal camera, including target photos of wineglasses under various sunlight conditions. We also took extra background images to use with our rendered image. We even used a silver ball to attempt environment mapping. With a little creative placement of these images all around our subject and careful lighting placement, we were able to effective recreate our scene conditions under all transmission and refelctions directions in our glass. We used a silver ball and glass sphere as test objects to make sure all directions were decently represented in our test image. We also took time to accurately model a table surface for our glass with a realistic texture pulled from a Pergo web page and dailed in for proper illumination.
To achieve this effect, we would like to implement the techniques described in Henrik Wann Jansen's paper "Efficient Simulation of Light Transport in Scenes with Participating Media using Photon Maps." Gummy Bears are a kind of participating media that will require light transport techniques not provided by PBRT, and photon mapping is very good at handling participating media in a manner that increases efficiency and reduces noise. We are also looking at the techniques described in Henrik's book "Realistic Image Synthesis Using Photon Mapping" regarding caustics photon mapping.

The most challenging part of our project involved implementing the photon mapping algorithm as explained in Henrik Wann Jenson's excellent book, Realistic Image Synthesis Using Photon Mapping. After developing a general global photon map and a way of "painting" dots to demonstrate the placement of photons, we next worked on a separate caustic photon map to increase the resolution of the caustics generated by the glass that would be the centerpiece of our image. We did render a few Cornell Box-like test images to make sure our algorithm was working correctly. We also ended up finding a fiar amount of bugs in the LRT Path Tracing integrator in the process of exploring diffuse reflections with this box. We later realized that these diffuse reflections would add little to our particualr schene, and so built a modified Whittig ray tracer with photon mapping activated under the Monte Carlo heading to enable us to call either from RIB files.
Our final caustic map can be targeted using one or two ciircles specified in the photon mapping code. Samples are regularly generated over this area, bounced around according to a russian roulette system, and then stored in Jenson's photon map data structure. For the caustic photon map, we ony store photons from this target that hit specular surfaces on the first bounce. This gives us an excellent sample of the caustic genreating photons. Eventually, we also used the cognac glass data from Jensen's book make sure our glass model and photon map systems were working correctly.

However, even without a final gather step it is possible to achieve images such as the one below. The image on the left shows the contribution from direct lighting only and the image on the right was rendered using photon mapping. The image on the right does not use a final gather step. Only 26,000 photons actually made it into the window and 500 were used in the radiance estimate. Notice the color bleeding on the yellow ball and on the floor.
