SpectralUplifting

Interactive sandbox for comparing different sampling strategies across measured luminaires and reflectance datasets.

What This Project Does

It evaluates how well different sampling approaches reconstruct color from spectral data. It combines:

• measured illuminant spectra (A, D65, F11)
• measured reflectance spectra (XRite patches)
• CIE color matching functions (X, Y, Z)

The app computes XYZ values and converts them to sRGB for comparison.

Implemented Sampling Methods

• Fixed wavelength buckets (Riemann-Sum sampling)
• Random Monte Carlo sampling
• Hero wavelength sampling

Build And Run
