My final project is to render a gemstone that can have dispersion effect, including the following progresses:

• Extend BRDF to BSDF - using GGX and BSDF importance sampling

(Reference: https://www.cs.cornell.edu/~srm/publications/EGSR07-btdf.pdf)

• Set up appropriate lighting for a round brilliant cut diamond model

(Model: https://sketchfab.com/3d-models/blue-diamond-free-giveaway-618d614891354c1f86f07845080e13e7)

• Generate dispersion by supporting ior that varies with RGB wavelength and splitting the refracted ray across different channels

(Reference: https://refractiveindex.info/, https://en.wikipedia.org/wiki/Sellmeier_equation)
