Patent ID: 8427470

Claim:
A non-transitory computer-readable medium storing therein an information display program that causes a computer to execute a process comprising: acquiring a 3-dimensional structural data pair that includes 3-dimensional structural data for a display subject and 3-dimensional structural data of a comparison subject that is compared to the display subject; extracting as a display surface of the display subject and from among display subject surfaces identified by the display subject acquired at the acquiring, a surface that is within a given distance from a comparison subject surface identified by the comparison subject; selecting a reference point from among vertices forming the extracted display surface of the display subject, the selecting being based on the amount of characteristics of the vertices; generating the normal of the selected reference point; setting a rotation axis about which the generated normal of the reference point is rotated to point in a counter viewing direction; calculating based on the normal of the reference point and the normal of the display surface and according to the uneven shape of the display surface, an angle of rotation by which the normal of the reference point is rotated about the rotation axis to point in the counter viewing direction; converting coordinates of the vertices into coordinates of the vertices in a state where the normal of the reference point has been rotated by the calculated angle of rotation and points in the counter viewing direction; and drawing on a display screen and based on the amount of characteristics, the display surface of the display subject, from a viewing direction subsequent to conversion at the converting.
