What is facial topology?

Facial topology refers to the structured representation of a human face in 3D modeling and computer graphics, focusing on the arrangement and flow of polygons, edges, and vertices. It is crucial for achieving realistic facial animations and expressions, as it determines how the mesh deforms during movements. Proper facial topology ensures efficient rendering and minimizes issues such as stretching or collapsing of the mesh. Overall, it plays a key role in character design, animation, and visual effects in various media.
