ABSTRACT:
A moving 2D cursor is mapped onto a guiding entity in a virtual 3D space displayed on a 2D surface by determining if the guiding entity has a characteristic that may yield a discontinuity in motion along the guiding entity when the moving cursor is mapped onto the guiding entity. The cursor is mapped onto the guiding entity based on a result of the determining.
