摘要： A computer-based method enables a selected part of a three-dimensional image on a screen to the followed throughout the three-dimensional image. In one embodiment, the method includes selecting a part included in the image, removing any obstacles included in the image that impede viewing of the part, moving a cursor along the part while constraining the movement of the cursor to the selected part, and, while moving the cursor, automatically removing, in a selected area of the viewing screen, any further obstacles appearing that impede viewing of the part during moving of the cursor so that the cursor can follow the geometry of the part. Thus, a user is provided with an unimpeded view of the part in the selected area when following the geometry of the part.
