This Geometry Nodes system simplifies the creation of hair cards for games and real-time rendering engines. By providing a set of hair curves, predefined hair cards, and a target surface such as a character's head, the node setup automatically generates the deformed geometry.

The resulting hair cards flow smoothly along the input curves. Additionally, the system automatically aligns the twist of each hair card to match the normals of the underlying surface geometry, ensuring consistent volume and outward facing textures.
