Samples along X. A finite integer ≥ 2.
OptionaldepthTotal extent along Z; defaults to 1.
Row-major heights — heights[row * columns + column] is the Y of the
sample at grid position (row, column), where column advances along +X
and row along +Z. Length must be exactly rows * columns, every value
finite (§85).
Samples along Z. A finite integer ≥ 2.
OptionalwidthTotal extent along X; defaults to 1. The field is centred on the origin.
