Assignment 8 – Path Tracing

Now, instead of just doing one bounce I do multiple bounces in an effort to find the light. With path tracing the colors from different surfaces start to bleed onto other surfaces. This is caused when the light isn’t found in the first bounce and lighting comes from another surface. Too many bounces before hitting the light and the contribution to lighting the surface is very low.

I added color to my original room in order to show the bleeding of colors onto other surfaces.

Only 16 samples per pixel…needs many more for less noisy picture.

Some red bled onto yellow parts of the wall.

Can see both red and yellow on the Sun God.
