Research On 3D Realistic Character Binding Method Based On Grid Topology Technology

In recent years,a large number of 3D realistic characters driven by dynamic capture have appeared in 3D animation,film,virtual anchor,metauniverse and other products.How to improve the efficiency of role binding,use dynamic capture data to drive role model and ensure the authenticity of role model movement has become a hot spot in the industry.Traditional bone binding technology usually requires animators to manually build bones,assign Skin Weights and add control drivers.It takes a long time and has a high technical threshold.It is difficult to meet the current large number of needs of animation,games and virtual digital people.The motion law of realistic 3D personas is highly consistent with that of real characters,which makes it possible to realize mass character binding.The specific method is to establish a set of standard human body binding model and transform the standard mesh model into a user-defined target mesh model by using mesh topology technology,so as to ensure the character mesh modeling and continue the bone and weight information of the standard shape at the same time.This method can complete the whole process of bone binding in a short time,greatly reduce the workload of designers,and is suitable for batch realistic character model binding.
