1. A method for generating a virtual character, the method comprising:
performing mesh simplification on an initial model of the virtual character by using a standard mesh simplification algorithm with a mesh simplification mark, to obtain a mesh-simplified model; wherein the mesh simplification mark is used to indicate that a degree of mesh simplification on a facial area of the initial model is less than a degree of mesh simplification on other areas;
obtaining a first target model by performing white model mapping rendering on an area of each material type on the mesh-simplified model, and obtaining a second target model by performing hyper-realistic rendering on the area of each material type on the mesh-simplified model; and
establishing a bidirectional mapping between the first target model and the second target model, and obtaining a target virtual character through iterative updating of the bidirectional mapping.
