1. A three-dimensional data display device comprising:
- a rendering unit which is configured to obtain two-dimensional data by rendering three-dimensional data on the basis of a viewpoint;
an identification unit which is configured to identify a point of interest which is a point designated by a user of points in the three-dimensional data;
a viewpoint control unit which is configured to move the viewpoint along an annular movement route surrounding the point of interest with a sight line directed toward the point of interest; and
a route setting unit which is configured to receive an input of the geometric parameter settings of the movement route,wherein the route setting unit determines an extending direction of a rotation axis of the movement route, and sets a straight line extending in the determined direction passing through the point of interest, as the rotation axis, andwherein the rendering unit is configured to render a solid figure which represents the movement route and the three-dimensional data when the route setting unit is configured to receive the input of the geometric parameter settings.

8. A method of displaying three-dimensional data comprising:
-
obtaining two-dimensional data by rendering three-dimensional data on the basis of a viewpoint; identifying a point of interest which is a point designated by a user of points in the three-dimensional data; moving the viewpoint along an annular movement route surrounding the point of interest with a sight line directed toward the point of interest; receiving an input of the geometric parameter settings of the movement route; determining an extending direction of a rotation axis of the movement route; setting a straight line extending in the determined direction passing through the point of interest, as the rotation axis; and rendering a solid figure which represents the movement route and the three-dimensional data when receiving the input of the geometric parameter settings.

9. A non-transitory computer-readable computer medium storing a program which causes a computer to execute functions, the functions comprising:
-
obtaining two-dimensional data by rendering three-dimensional data on the basis of a viewpoint; identifying a point of interest which is a point designated by a user of points in the three-dimensional data; moving the viewpoint along an annular movement route surrounding the point of interest with a sight line directed toward the point of interest; receiving an input of the geometric parameter settings of the movement route; determining an extending direction of a rotation axis of the movement route; and setting a straight line extending in the determined direction passing through the point of interest, as the rotation axis; and rendering a solid figure which represents the movement route and the three-dimensional data when receiving the input of the geometric parameter settings.
