Content item display method and computer-readable medium

A content display method for instructing a display device to express a hierarchical relationship between a plurality of content pieces and a plurality of folders, for which prepared are a virtual space in which arranged are the plurality of content pieces that may have a hierarchical relationship with each other and are possessed by a user and a plurality of objects representing each of the plurality of folders that may have the content pieces at a lower level in the hierarchical relationship, and a virtual camera that captures and generates an image of the virtual space,

• the method comprising:
• when a first object, a second object, and a third object have a hierarchical relationship between a parent, a child, and a grandchild, arranging the first object, the second object, and the third object in the virtual space so that a part of a first face of the first object is adjacent to a part of a second face of the second object, and a part of a third face of the second object is adjacent to a part of a face of the third object;
• when the first object and a fourth object have a hierarchical relationship between a parent and a child, arranging the first object and the fourth object in the virtual space so that a part of the first face of the first object is adjacent to a part of a face of the fourth object;
• instructing the display device to display the image of the virtual space captured by the virtual camera according to an instruction of the user to the virtual camera;
• and
• when a first adjacency in which a part of the face of the second object is adjacent to a part of the first face of the first object has already been achieved, and a second adjacency in which a part of the face of the fourth object is further adjacent to a part of the first face is to be achieved, if the second adjacency cannot be achieved because the first face does not have enough area, transforming the second object and/or the fourth object so that the second adjacency can be achieved by reducing the face of the second object and/or the face of the fourth object.

• when the first object and a fourth object have a hierarchical relationship between a parent and a child, arranging the first object and the fourth object in the virtual space so that a part of the first face of the first object is adjacent to a part of a face of the fourth object;
• instructing the display device to display the image of the virtual space captured by the virtual camera according to an instruction of the user to the virtual camera;
• saving a predetermined hierarchical relationship, which is the hierarchical relationship at a predetermined point in time, in a storage device;
• and
• upon instructions of an operator to edit an object A and to change the hierarchical relationship after the predetermined point in time, restoring the hierarchical relationship to the saved predetermined hierarchical relationship while keeping the object A edited.

• when the first object and a fourth object have a hierarchical relationship between a parent and a child, arranging the first object and the fourth object in the virtual space so that a part of the first face of the first object is adjacent to a part of a face of the fourth object;
• and
• instructing the display device to display the image of the virtual space captured by the virtual camera according to an instruction of the user to the virtual camera, wherein
• when one object and the other object have a parent-child relationship, a plurality of combination rules are predetermined for a predetermined face X of the one object and a predetermined face Y of the other object when the predetermined face X and the predetermined face Y are adjacent to each other, so that a part of the face X is adjacent to a part of the face Y, and one of the plurality of combination rules is selected depending on whether the one object and the other object are adjacent one above the other or one behind the other.
