Claim 9:
10. An animation character control method, performed by a processing device, the method comprising:
obtaining a driving deformation base with a first set of multiple basis components corresponding to a driving character and a driven deformation base with a second set of multiple basis components corresponding to a driven character, the driving deformation base being different from the driven deformation base, the driving character having a corresponding structural base, the driven character having no corresponding structural base, the structural base being used for identifying structural features of a corresponding character, and the deformation base being used for identifying deformation features of a corresponding character, wherein a deformation base for a character of a character type is formed by deformable meshes representing different deformations for the character type whereas a structural base for the character is formed by deformable meshes representing different structural shapes of the character type;
determining a mapping relationship between a deformation parameter corresponding to the driving character in the driving deformation basis and a deformation parameter corresponding to the driven character the driven deformation base, wherein the deformation parameter represents weighting coefficients of deformable meshes representing different deformations in the driving or driven deformation base; and
controlling the driven character according to the deformation parameter corresponding to the driving character, the driven deformation basis, the face customization base of the driving character, and the mapping relationship, without relying on the structural base of the driven character.
