Introduction Hair Rendering Approaches for high-fidelity hair rendering typically utilize strand-based modeling. With this technique, each individual hair strand is represented as a curve primitive. Hundreds of thousands of these strands are then combined to form the hair volume. Because this approach accurately represents the macrogeometry of real hair, physics and lighting can be accurately simulated—especially with path tracing. The visual accuracy of strand-based rendering comes with considerations for use in real-time settings. For one, the sheer complexity of the combined geometry has a considerable performance cost. Effective implementations also typically require specialized rendering pipelines, as strand-based hair rendering does not fit neatly into a conventional rasterization workflow. Despite this, strand-based hair has been successfully implemented in multiple real-time settings (e.g., Unreal Engine 5 and REDEngine ). Given the constraints of strand-based hair, a popular alternative approach is to render hair via hair cards . A hair card is a flat quad that represents a clump of hair strands. Textures are applied on each card to depict individual strands. By layering multiple cards on top of one another, the illusion of voluminous hair can be achieved at a relatively low performance cost.
