DISPLAY METHOD FOR GUIDING IN THREE-DIMENSIONAL OBJECT SPACE

摘要

PROBLEM TO BE SOLVED: To provide a guiding method to efficiently support to proceed forward in a three-dimensional object space such as in a path or conduit which is complicated with many branches.

SOLUTION: This method has a step to decide the sightline direction for the position in the image of the event operated by a user in the three-dimensional object space displayed on the screen, and a step to decide the possible moving direction depending on the current position and the above sightline direction in the three-dimensional object space by using the event generated position as the current position and display the cursor by changing its shape to indicate the possible moving direction.
