Abstract:
Virtual object display apparatus for displaying a virtual environment along a display direction from a display position to a reference point in three-dimensional virtual space, the display position being fixedly located behind a viewpoint of a walking human model relative to a walking direction, the reference point being located forward of the walking direction, the human model consisting of a plurality of body parts, comprising:key frame memory means for storing a set value for each body part, wherein said set value corresponds to a unit sample of a walking motion in the three-dimensional virtual space, and wherein one step of the walking motion includes a plurality of unit samples;swing calculation means for calculating the viewpoint of the human model for each unit sample of the walking motion in order according to the set value of each body part of the human model for the unit sample of the walking motion;display position setting means for calculating a display position corresponding to the viewpoint of the human model in the three-dimensional virtual space for each unit sample of the walking motion; anddisplay means for displaying the virtual environment in three-dimensional virtual space along the display direction from the display position to the reference point, wherein the display direction is changed in synchronization with change of the viewpoint of the human model by the unit sample of the walking motion.
