Concerned with optical ambiguity and the phenomenology of perception, each cube was intended to be
shown at a different elevation and with different lighting effects so as to always be experienced in a new way.
«We examined the evidence for a time - dependent
elevation bias in the reconstruction by regressing mean MXD against mean sample
elevation for
different age classes of trees... These results (
shown in [their] Table 2) indicate no significant elevational influence on mean density,
at least over the range of
elevation involved in these calculations»
