Tessellation Shader

A Tessellation Shader is a graphics program used in 3D rendering that enhances the detail of objects dynamically. It divides existing surfaces into smaller patches or triangles to add more intricate surface details, making models appear more realistic without manually modeling every detail. This process allows for smooth, high-quality visuals, especially close-up or on complex surfaces like terrain or fabrics, while optimizing performance. Essentially, it automates the refinement of surfaces during rendering, ensuring detailed visuals efficiently and adaptively based on the viewer’s perspective.
