moved to jittered source positions (more or less "motion blur") and it is a lot smoother - some photosensitivity on the previous one, I was feeling it

some pending issues related to reflection, I'm getting a lot of nans there and I'm not sure why yet

looking at live editing of spectral distributions with a source PDF and some spectral filter data that I got from a company that does stage lighting

with xRite color chips based on sRGB reference values from https://xritephoto.com/documents/literature/en/ColorData-1p_EN.pdf and reflectances from the supplemental code here https://rgl.epfl.ch/publications/Jakob2019Spectral

A Low-Dimensional Function Space for Efficient Spectral Upsampling ...

We present a versatile technique to convert textures with tristimulus colors into the spectral domain, allowing such content to be used in modern rendering systems. Our method is based on the observation that suitable reflectance spectra can be represented using a low-dimensional parametric model ...

#

this is doing a pretty basic convolution of the light distribution being configured, the wavelength color, and the reflectance for the color chip, across the visible spectrum

#

pretty compelling little ui
