Creative Images

My creative image consists of a double mirror, to create the illusion of a hallway of mirrors. The second mirror is placed right behind the camera, so it is not visible. There are two dielectric spheres, one with an index of refraction of 1.33 (water) and the other is 1.52 (glass). The other sphere and the walls are shading using the Phong material. The frame of the mirror and floor are both shaded using Lambertian shading.

Design Choices

There weren't many new decisions to be made for this project because we were implementing new materials. Below are some of the design decisions I made:

For the most part, I followed the pseudocode given in the class slides.
I used the halfway vector for the phong shading.
I used the Schlick approximation for the metallic and dielectric materials.
I decided to implement the ray tree pruning optimization using a minimum attenuation. This was extremely effective in speeding up the rendering time.

Extra Credit

I didn't implement the extra credit.
