Three-dimensional object manipulating apparatus, method and computer program

A three-dimensional object manipulating apparatus, comprising:

• a display means for displaying a three-dimensional object on the screen of a display unit;
• a coordinate detecting means for detecting a coordinate defined on the display screen by a user's touch;
• a determination means for determining a moving direction for the three-dimensional object in a predetermined cycle on the basis of the coordinate detected by the coordinate detecting means and barycentric coordinate of the three-dimensional object on the display screen;
• and
• an object moving means for moving the three-dimensional object on the basis of the result of determination supplied from the determination means.

• a display means for displaying a three-dimensional object on the screen of a display unit;
• a coordinate detecting means for detecting a coordinate defined on the display screen by a user's touch;
• a determination means for determining whether the three-dimensional object is to be scaled up or down in a predetermined cycle on the basis of the coordinate detected by the coordinate detecting means;
• and
• an object scale-up/-down means for scaling up or down the three-dimensional object on the basis of the result of determination supplied from the determination means.

A three-dimensional object manipulating method in which a display unit, data processor and a coordinate detector which detects a coordinate defined on the display screen by a user's touch are used, the method comprising the steps of:

• displaying, under control of the data processor, a three-dimensional object on the display screen;
• determining, under control of the data processor, an axis and direction of rotation for the three-dimensional object in a predetermined cycle on the basis of the coordinate detected by the coordinate detector;
• and
• rotating, under control of the data processor, the three-dimensional object on the basis of the result of determination.
