Display control device, display system, and display method

A display control device comprising:

• an instruction processor to provide an instruction for change of a display angle of a display space area that is a three-dimensional coordinate space in which a display object is displayed;
• and
• a drawing processor to rotate and draw the display space area and the display object on a basis of the instruction received from the instruction processor, extract a side serving as a contour line of the rotated display space area displayed on a two-dimensional screen, from among sides that configure boundary surfaces of the rotated display space area, and draw label information at a position adjacent to the extracted side and outside the rotated display space area, for output,
• wherein, in a case where two sides along a same coordinate axis of the three-dimensional coordinate space, among the sides that configure boundary surfaces of the rotated display space area, are sides that configure the contour line of the rotated display space area, the drawing processor extracts one of the two sides.
