Claim 12:
13. The apparatus according to claim 12, wherein:
the driving character is a character having the corresponding face customization base in a first character and a second character, and the driven character is a character that has no corresponding face customization base among the first character and the second character; and
to determine the mapping relationship comprises:
determine a target mesh according to a first expression parameter and a first expression base corresponding to the first character, the first expression parameter being used for driving a first quantity of dimensions of the first expression base, the target mesh having a target vertex topology used for identifying the first character that makes an expression corresponding to the first expression parameter;
obtain a target expression base corresponding to the first character having the target vertex topology and having a second quantity of dimensions, the target expression base being determined according to a second expression base corresponding to the second character;
determine a second expression parameter corresponding to the first character according to the target mesh and the target expression base, the second expression parameter being used to reflect a change degree of the expression of the first character relative to the target mesh; and
determine the mapping relationship between the expression parameter corresponding to the driving character and the expression parameter corresponding to the driven character according to the first expression parameter and the second expression parameter.
