On March 7th, route of flight Alaska Airlines 870 was slightly adjusted to meet the path of the solar eclipse happening on that day. On board was astronomer Mike Kentrianakis, who recorded the following video where the eclipse is visible from begin to end.
The Italian company CoeLux has apparently managed to create an artificial light which uses a material that mimics the atmospheric scattering, to look like sunlight and light from the sky. Judging from the photos and videos available on their website, it seems the look is very convincing.
As they point out, this could have a serious impact on architecture, as available sunlight is a factor in the design of buildings. Unfortunately, at this stage it is a prohibitively expensive product for the average consumer, and likely targeted at the construction industry. But it might be only a niche for some years before expanding to a larger scale.
The news websites PetaPixel and Colossal have previously covered this topic last month, and included some larger product photos made available by the company. But the most interesting coverage might be the one by Lux Review, who met CoeLux at an exhibition booth and made the following video. From their article:
No, the light source doesn’t move… yet. No, the colour temperature isn’t dynamic… yet. The void height needed is a metre. It consumes 340W of electrical power, but that will come down as LEDs improve.
I’m a bit late to the party, noticing that Mikko Kallinen, co-founder of Praxis, wrote a series of articles presenting an overview of the tech involved in the rendering engine he’s writing.
The results are visually impressive, so it’s very unfortunate he doesn’t give more details. This video in particular, showcasing real-time atmospheric effects is outstanding.
