I kind of thought this video was going to be about Flatland the book but it was even better. This is a fantastic and easily digestible explanation of ray tracing.

Folks that like this, might find this interesting, an incredible resource for my then younger mathematical mind: https://www.dimensions-math.org/Dim_E.htm

An exploration of 3d via projections in 2d then 4d via projections in 3d.

Great video! This references the fantastic book Flatland, which helps explain dimensionality in really easy to understand way, and helped me get my head around what a 4th or n level dimension is (and why we it’s so unintuitive for us 3-dimensional beings)
