  • the object data storage section 176 stores a plurality of base objects and a plurality of part objects each of which can be attached to at least one of the base objects for each game character. Specifically, since each game character has a different head shape and height (head position), it is necessary to change the shape of the base object and the attachment positions of the base object and the part object (positions in the local coordinate system of the game character) corresponding to the game character to which the base object and the part object are attached.

  • the scale value may be input to each of the three axial directions of the base bone BB.
  • the scale value input to the base bone BB is reflected in the virtual part bone VB so that the position and the size of the virtual part bone VB change. Since the position of the part bone PB is constrained by the virtual part bone VB, the part bone PB only changes in position (i.e., the size of the part bone PB does not change). The part object PO also only changes in position.
  • the base object BO for the game character A is deformed by inputting a scale value into the base bone BB of the base object BO.
  • the position (attachment position) of the part object PO is changed according to the deformation of the base object BO, and thus the part object PO for the game character A becomes a part object PO for the game character B.
  • FIG. 11 illustrates the motion of the part object according to this embodiment.
  • the part object PO is caused to make a motion by controlling the bone PB (part bone) of the part object PO based on the physical simulation information (e.g., weight and inertial force) about the part object PO, as illustrated in FIG. 11 .
  • the physical simulation information e.g., weight and inertial force

  • shape information, scale information, color information, motion data, and the like corresponding to a predetermined combination of the base object and the part object are stored as table data, and the shape, size, color, and motion of the part object are changed referring to the table data.
  • the game character is drawn without changing the shape and the like of the part object PO attached to the base object BO.
  • the part objects “front hair C” and “back hair G” are selected as the part objects PO (see FIG. 12B )
  • the game character is drawn while enlarging the part object “front hair C” (part object PO) attached to the base object BO in the front-and-back direction.
