In a fluorescent context, non-fluorescent surfaces are spectral singularities, just like mirrors are singularities in the geometric domain. We enable bidirectional connections between non-fluorescent surfaces in a fluorescent bidirectional path tracer with a spectral regularization approach.

We improve upon our previous fluorescent spectral uplifting paper with different error metrics for faster convergence and alternative fluorescence parameterizations.

Given an input RGB tristimulus value, our method automatically provides a mixture of a regular, smooth reflectance spectrum plus a fluorescent part. For highly saturated input colours, the combination yields an improved reconstruction compared to what would be possible relying on a reflectance spectrum alone.

We present an analytical BBRRDF model that separates reflectance and fluorescence into spectra.
