Spectral Monte-Carlo methods are currently the most powerful techniques for simulating light transport with wavelength-dependent phenomena (e.g., dispersion, colored particle scattering, or diffraction gratings). Compared to trichromatic rendering, sampling the spectral domain requires significantly more samples for noise-free images.

Spectral gradient samples are taken using pairs of paths which are correlated by a spectral shift map- ping that maps a base path x sampled using the wavelength λ to an offset path x′which contributes to the wavelength λ′. appearance of path pairs using multiple importance sampling or handle non-invertible shifts.

GitHub - TomCrypto/Lambda: Spectral Path Tracer
https://github.com/TomCrypto/Lambda
Spectral Path Tracer Lambda is a simple spectral path tracer, written in C++. Some parts of the code are still written in C and don't take advantage of C++ features for the moment. This is a work in progress as many features are still missing, but it is quite functional.
Spectral path tracing - image color/brightness incorrect
https://computergraphics.stackexchange.com/questions/2206/spectral-path-tracing-image-color-brightness-incorrect
All calculation in the path tracer uses standard illuminant and macbeth color checker SPD, spectral power distribution. The result of the path tracer for each pixel is the SPD obtained as a sum of SPD obtained from each sample calculated by the pat tracer. This SPD is then converted to CIE XYZ color and to RGB.

Monte Carlo Path Tracing

Solving this equation in the main goal of Monte Carlo Path Tracing. The rendering equation is sometimes written more compactly in operator form. An operator is a method for mapping a function to another function. In our case, the function is the radiance. L= L e+ K L 4
Spectral rendering - Wikipedia
https://en.wikipedia.org/wiki/Spectral_rendering
In computer graphics, spectral rendering is a technique in which a scene's light transport is modeled with real wavelengths. This process is typically slower than traditional rendering, which renders the scene in its red, green, and blue components and then overlays the images.
