1. An apparatus for modifying a virtual object in a virtual environment, the apparatus comprising:

  • a memory for storing code that defines a set of instructions; and

    a processor for executing the set of instructions to;

    (a) generate a virtual object in a virtual environment;

    (b) determine a position of a virtual tool in the virtual environment in response to a location of a user in real space, wherein the virtual tool comprises a plurality of discrete point locations for sensing penetration into the virtual object; and

    (c) reposition the virtual tool substantially tangent to a surface of the virtual object substantially at the start of a modification of the virtual object by the user.
