ABSTRACT:
A computer method and apparatus for combining a brush object element with a trajectory object element in a graphics display system. The brush has a reference point that moves along a trajectory, and any point in application coordinates that is at any position covered by the brush, is assigned an -inside- indication. The trajectory may be non-closed or closed, in which latter case it may also govern an -inside- indication. The approach is point driven, which leads itself to acceleration by means of array calculations.
