Homework 5 - Path Trace Cornell Box
The images below are spectral ray traced images of the cornell box with 6400 samples per pixel. The ray tracer
is implemented such that after the spectral XYZ channels are evaluated for each pixel, a user may further specify
the exposure level and the gamma scale. The exposure setting maps the average Y channel value to a given
middle grey value (similar behavior as a digital camera), the default middle grey is .18. Below are the resultant
images, first varying the exposure level, and the second row varies the gamma correction value.
