A method according to one embodiment includes applying a photoresist to a substrate; exposing the photoresist such that a local intensity of radiation applied to the photoresist at each pixel thereof is a function of a mathematically-generated representation of a target surface shape; developing the resist; and performing a subtractive process on the developed photoresist and the substrate for creating the target surface shape on the substrate. A method according to another embodiment includes applying a photoresist to a substrate; patterning the photoresist using a machine-readable profile; and performing a subtractive process to transfer the profile onto the substrate.
