For years, we have looked at something solid to be able to implement 3D colour science visualisation. We used Vispy, but encountered some issues when interacting with the scenegraph, then a quick stint with Three.js which required doing dirty things to pass Python data to Javascript, and finally, Pygfx is the one that enabled us to do what we wanted: https://github.com/colour-science/colour-visuals
How is Bitsight "observing" here?
Wētā FX used it on The Hobbit for example: https://www.facebook.com/marvelousdesigner/photos/james-moor...
The tags are used to colour my knowledge graph.
SEGA HOME STAR EXTRA
This is currently one of the best of the home planetarium projectors, unfortunately it is SOLD OUT. The field of view is the largest available, the optics are excellent and available features are numerous. One of the nicest features is the random shooting star which is very effective. You can set the time and date for your night time viewing. There are three rotational speeds. The rotation is done by direct gearing and is silent. Brightness is excellent and the stars have sharp detail. The discs have a 120,000 star count. We have taken this machine completely apart and the engineering is excellent.
> _with is a curve option that indicates how this dataset should be plotted. It’s _with and not with because the latter is a built-in keyword in Python. [1]

This is correct, however, not everything is lit by sunlight, especially onset in the motion picture industry, where solid state lighting and its narrow band irradiance sources, e.g. led lights or led walls, are prevalent. Those emission sources induce a lot of unexpected appearance problems, e.g. metameric failures that RGB rendering cannot possibly solve. Our spectral renderer, i.e. Manuka [1], was specifically designed to address those issues whilst imaging with a virtual motion picture camera.
One recent example I have in mind is The Batman (2022): There are sequences/shots lit with high-pressure sodium lights (HPS), those have a flat spectrum with spikes between 500 and 600nm, the appearance of objects lit under them is very specific and can only be accurately reproduced with a spectral renderer such as Manuka, Mitsuba [2] or Art [3].
