ABSTRACT:
Inputs to a line scan stepper of a line scan converter are generated for a line segment so that the inputs are rendered in a predetermined rendering direction. The predetermined rendering direction includes an implied orientation for line segments that have an implied orientation, such as single line segments and line segments that are part of a polyline. The predetermined rendering direction also includes a consistent direction for polygon edge line segments. For adjacent line segments of a polyline, vertices are swapped in a virtual manner so that a vertex that is shared between the adjacent line segments need be provided only once to the line scan converter.
