Apparatus for controlling the shift of virtual space and method and program for controlling same
First Claim
1. A virtual-space shift control apparatus comprising:
- a detecting element that detects a touch operation or a drag operation of a pointing device having a plurality of pointing elements, performed on a display screen;
a viewpoint-position information generator that generates viewpoint position information of a virtual space image based on the detected touch or drag operation of the detecting element; and
a three-dimensional image generator that generates data on the virtual space image seen from a viewpoint indicated by the viewpoint position information and outputting a three dimensional image to the display.

Abstract
A virtual-space shift control apparatus includes a detecting element that detects a touch operation or a drag operation of a pointing device having a plurality of pointing clements, performed on a display screen and a viewpoint-position information generator that generates viewpoint position information of a virtual space image based on the detected touch or drag operation of the detecting element. A three-dimensional image generator is provided that generates data on the virtual space image seen from a viewpoint indicated by the viewpoint position information and outputting a three dimensional image to the display.
