So I want to path trace a Cornel Box scene, but I don't understand the values given here in section 2 and 3.
No.2 Lists surface reflectances with respect to different wavelengths but I'm not using wavelengths. I thought this was done in spectral path/ray tracing where we are using photometry instead of radiometry.
Similarly No.3 lists Light properties though I don't understand what do the values in the
light column (0, 8, 15.6, 18.4) suggest.
I was merely expecting the specular and diffuse reflectivity in all 3 channels for each of the colors red, green and white.
