Claim 5:
6. The method according to claim 2, wherein:
the target vertex topology is a second vertex topology corresponding to the second expression base;
determining the target mesh according to the first expression parameter and the first expression base corresponding to the first character comprises:
determining an expressionless mesh corresponding to the second character with no expression from the second expression base corresponding to the second character;
determining, according to the expressionless mesh corresponding to the second character and the first expression base corresponding to the first character, an adjustment expression base corresponding to the first character having the second vertex topology, a quantity of dimensions of the adjustment expression base being the first quantity of dimensions; and
determining the target mesh according to the first expression parameter and the adjustment expression base; and

obtaining the target expression base corresponding to the first character having the target vertex topology comprises:
determining an expressionless mesh corresponding to the first character with no expression from the adjustment expression base; and
generating the target expression base according to the expressionless mesh corresponding to the first character and a mesh deformation relationship in the second expression base.
