Claim 0:
1. An animation character control method, performed by a processing device, the method comprising:
obtaining a driving expression base with a first set of multiple basis components corresponding to a driving character and a driven expression base with a second set of multiple basis components corresponding to a driven character, the driving expression base being different from the driven expression base, the driving character having a corresponding face customization base, the driven character having no corresponding face customization base, wherein an expression base for a character of a character type is formed by deformable meshes representing different expressions for the character type whereas a customization base for the character is formed by deformable meshes representing different facial shapes of the character type;
determining a mapping relationship between an expression parameter corresponding to the driving character in the driving expression basis and an expression parameter corresponding to the driven character in the driven expression base, wherein the expression parameter represents weighting coefficients of deformable meshes representing different expressions in the driving or driven expression base; and
controlling the driven character according to the expression parameter corresponding to the driving character, the driven expression basis, the face customization base of the driving character, and the mapping relationship, without relying on the face customization base of the driven character.
