Both boxes use the same geometry, rescaled into different typed
arrays. The left one stores
position/normal/uv as
Float32Array (32 bytes per vertex). The right one stores
them as normalized
Int16Array/Int8Array/Uint8Array
(11 bytes per vertex, a third the size) with the
normalized flag telling the GPU to rescale the integers
back to the same floats. Same shading, less memory.
