In 3D modeling, a subdivision surface is a technique that refines a base mesh by iteratively adding vertices and smoothing edges to generate a smoother, higher-resolution surface. It bridges low-poly (simple) and high-poly (detailed) models, allowing artists to work with a manageable base while creating complex, smooth geometry through adjustable subdivision levels. Widely used in animation, game development, and visual effects for organic shapes (e.g., characters) or curved surfaces (e.g., product designs), as it balances editability with high-quality results. To apply it effectively, start with a low-poly base mesh with clean topology, then gradually increase subdivision levels to control smoothness and detail.
