1. A method for a computer system comprising:

  • receiving a surface displacement for a location on a first surface of a model of an object from a user via a user input device of the computer system, wherein the first surface of the model of the object is determined in response to a first motion captured pose of the object;

    determining a weighted combination of a first surface displacement group and a second surface displacement group in response to the surface displacement in the computer system, wherein the first surface displacement group is determined in response to displacements between the first surface of the model of the object and a second surface of the model of the object, wherein the second surface of the model of the object is determined in response to a second motion captured pose of the object, wherein the second surface displacement group is determined in response to displacements between the first surface of the model of the object and a third surface of the model of the object, wherein the third surface of the model of the object is determined in response to a third motion captured pose of the object;

    determining a fourth surface of the model of the object in the computer system in response to the first surface of the model of the object and the weighted combination of the first surface displacement group and the second surface displacement group; and

    displaying the fourth surface of the model of the object to the user on a display of the computer system.
