A method is disclosed and includes determining at least one of a height field and an orientation field of a fiber-reinforced structure. The fiber-reinforced structure includes a plurality of fiber portions and a polymer matrix. The method includes generating a reaction-diffusion representation of the fiber-reinforced structure. The reaction-diffusion representation indicates a concentration of at least one of the polymer matrix and the plurality of fiber portions. The method includes designating a reference fiber deposition path based on the reaction-diffusion representation. The method includes generating a continuous fiber deposition path based on the reference fiber deposition path. The method includes transmitting a signal representing the continuous fiber deposition path to a deposition device, the deposition device using the continuous fiber deposition path to deposit a fiber of the fiber-reinforced structure.
