I was born cross-eyed, and although my eye sight was corrected surgically when I was 5, I was never able to do stereoscopic vision. I am starting to wonder now if that also impacted my understanding of 3D shapes. I am pretty good at envisioning 2D geometry, but I have a very hard time visualizing how 3D shapes like the platonic solids work. Of course, cubes and tetrahedrons are fine, but the fit of a dodecahedron or how to pack three pyramids to make a cube is beyond my abilities.

I have met other people who also have issues with 3D shapes, and at least one person also was born cross-eyed. Is there a correlation between stereoscopic vision and 3D visualization?

there's actually a strong correlation! the brain regions for stereoscopic vision and mental 3D rotation share neural pathways, so early visual development impacts spatial reasoning. some studies show people with stereoblindness rely more on monocular depth cues and often develop alternative visualization stratagies over time.

how to pack three pyramids to make a cube

How does this even work with *three* pyramids?
