Retopology is the process of creating a new 3D model with an optimized topology from an existing, often high-resolution, 3D model. Synonyms for retopology include remeshing, rebuilding, or recreating the model's topology. It involves creating a new mesh that conforms to the shape of the original model, ensuring that it has the right edge flow, topology, and level of detail to make it editable, animatable, and light enough to use in real-time rendering environments. Retopology is often used in the game development industry to optimize models for use in video games or virtual reality applications. Other synonyms for retopology include mesh simplification, mesh reduction, or low-poly modeling.
