We study the dependence of the dimensional character of the charge-densitywave (CDW) in TiSe$_2$ by a controlled variation of the number of availablecharge carriers in the conduction band. A change of dimensionality is realisedby H2O exposure and monitored by angle-resolved photoelectron spectroscopy. TheCDW spanning vector changes from 2x2x1 towards 1x1x2 in a narrow populationrange, just before a complete suppression of the CDW. Our findings enable a newview on the excitonic origin of the CDW, the relation between CDW spanningvector and periodic lattice distortion, and suggest modifications in thepicture of the recently discovered chirality of the CDW.
