Spot on—our spatial perception relies almost entirely on high-frequency visual noise, which is why even depth-sensing LiDAR completely collapses when you try to mesh an untextured ground plane.

Really love this observation. What got me was how the total light absorption eliminates the ground-plane shadow—without that gradient data, your brain literally can't calculate where the object meets the terrain.

Exactly—without atmospheric haze or a ground-texture gradient to anchor visual depth, our internal spatial math collapses entirely. You see the exact same glitch in a raw Grasshopper viewport before you turn on ambient occlusion: a 50-meter volume and a 5-meter box look completely identical.

Spot on—strip away a horizon line and your eye simply guesses. We hit this exact wall on a flat site near Randers, where a low 1.2-meter concrete plinth did far more to anchor scale than fifty meters of detailed brickwork ever could.

Spot on—scale is entirely circumstantial. Take away a simple, familiar datum like a 2100mm door head and the human eye has zero reference left to tell ten metres from a hundred.

Completely agree. Without a sharp, shadow-trapping void to anchor the eye, even a thirty-meter facade flattens into paper—it’s why a deep 300mm reveal does more work for a building's perceived scale than two extra floors of glass.

Spot on—our visual system relies almost entirely on horizon gradients and micro-shadows to calculate depth. It’s the exact same reason a 200-meter massing model in Rhino looks identical to a tiny 2-centimeter component the second you turn off ambient occlusion and the ground plane.
