I love the format of interactive educational documents, especially when you can tell that the 'teacher' is also the UI designer and developer in one <i>and</i> there's a very high level of quality and polish. There's nothing quite like it for learning a complex subject.<p>Check out the archives [1] for more amazing interactive documents by this author.<p>Can anyone share any more examples of this kind of thing? The OP's archives [1] are amazing.<p>[1] <a href="https://ciechanow.ski/archives/" rel="nofollow">https://ciechanow.ski/archives/</a>
Those are some well made demonstrations! Really intuitive and I think this would be a good theoretical starting point for anyone interested in computer graphics.<p>I think it should be clarified that with a real monochromatic cyan light source the tiles in this example [1] would be different hues of cyan, and not different hues of green, blue, and cyan (which is due to the cyan light source being modeled as a combination of green and blue light in the example).<p>[1] <a href="https://i.imgur.com/9685hzU.png" rel="nofollow">https://i.imgur.com/9685hzU.png</a>
This reminded me of an article about James Turrell and his experimentation with light as "not a tool to enable vision but something to look at":<p><a href="https://www.archdaily.com/380911/light-matters-seeing-the-light-with-james-turrell" rel="nofollow">https://www.archdaily.com/380911/light-matters-seeing-the-li...</a>
Great resource! (I love the amount of thought the author put into how learners might best grasp the concepts via examples that differ from the typical diagrams.) I only wish it had continued with more complex setups!<p>As someone interested in how light works for its impact on photography and cinematography, I’d like to find expanded similar resources.<p>The main one that comes to my mind is "Light: Science and Magic" (978-0415719407) which I own. Another possible learning tool (which I have not yet had a chance to use) is Cine Tracer: <a href="https://store.steampowered.com/app/904960/Cine_Tracer/" rel="nofollow">https://store.steampowered.com/app/904960/Cine_Tracer/</a><p>Any other books, sites, or software that might help one learn how to better understand or shape light?
Looks really nice, the widgets are great and run well on my phone. Is it a real time ray tracer doing the rendering? Still amazes me these days what’s possible in browsers or on a phone.
I sent this to several of my friends who are professional photographers and all they could say was ‘shhhh don’t give away our secrets.’<p>It’s all about the light. Really beautiful demonstrations.
My only complaint is that I hoped for a second half of the article with equally detailed visualizations, explaining the physically-based rendering algorithms used to create the visualizations in the first half. The last diagram showing multiple matte reflections is just a teaser.
