In this lesson I learned how to topology and the importance of topology. First of all, topology is the process of converting a high resolution model into a smaller model that can be used for animation. Secondly, we should pay attention to the principle that the topology should follow the animation needs. For example, in the parts where muscle movements are more obvious, it is important to ensure that there are more faces and that they are all quadrilateral to avoid stretching. In the parts where the movement is not obvious or is not present multilateral faces can be hidden in. Protect the necessary structures of the body with loops to avoid deformation of the joints.
