Sometimes I think that 3D doesn't actually exist. Just a fudgey gloss linking the way we see with a nice way to model it. A convenient illusion. It's hard to rationalize because it is fundamentally irrational.

Would you credit Brunelleschi for this illusion https://en.wikipedia.org/wiki/Filippo_Brunelleschi https://en.wikipedia.org/wiki/Filippo_Brunelleschi https://en.wikipedia.org/wiki/Perspective_(graphical) https://en.wikipedia.org/wiki/Perspective_(graphical)

  I'd credit biology, culture... the usual authors of our thinking.

    You would describe as an innate and obvious part to the environment. Interesting how something that took 1000s of years to articulate is just innate to the layperson in the modern world.

      No doubt there are many cases of exactly that. And articulation is of rather arbitrary value. I wouldn't put it on a pedestal.

        I'm not putting it on a pedestal. I'm afflicted with the need to know the source of beliefs. It could be with more study one might find the value is anything but arbitrary. I guess I should bow out of this thread since I'm never really sure what we are discussing. One certainly doesn't need to understand the foundations of understanding to get by in the modern world. I can't really cope without knowing the roots of why we do what we do.

What do you mean, 3D doesn't actually exist?
- detourdog 4y ago
  That is why I asked about Brunelleschi. Since that is where I think our system of understanding 3-D came from.

    As a side remark, it is probable [0] that Brunelleschi built his understanding of perspective from the Books of optics [1], written by Ibn al-Haytham around 1020 AD.

      No doubt that is what happened. Thanks for the deeper source.

        I read a little of the book of optics and I could see it influencing Brunelleschi. The other reference requires a login so I wasn't able to look into the claim.

  I mean that the world isn't actually composed of a 3d space filled with 3d stuff. That 3d is just a way of thinking about it.
  - detourdog 4y ago
    That is how I read the comment but wasn't sure. I asked about the source of 3-D space I was aware of.
