Morphology

three-dimensional = three + dimensional (transparent) = three + dimension + al

The adjective is a straightforward compound of the numeral 'three' and 'dimensional' (itself 'dimension' + '-al'), so the overall meaning 'having three dimensions' is directly predictable.

Etymology

Three-dimensional comes from three and dimension, where dimension means a way to measure or a direction, like 'length', 'width', and 'depth'. So something three-dimensional has those three measures and is not flat.
