FillRule¶

Overview¶

Type FillRule¶

Fill rules, for determining how to fill a path (given the winding number of a face)

Nonzero The path will be filled when it's winding number does not equal zero. In general this fill rule is the default for PhET Scenery Stack rendering. For more info see: https://en.wikipedia.org/wiki/Nonzero-rule

Even-odd The path will be filled when the winding number is odd. For more info see: https://en.wikipedia.org/wiki/Even%E2%80%93odd_rule

Positive / Negative These fill rules are used for 3D rendering. Only paths that have counter-clockwise orientations will be filled in the positive fill rule (facing the camera). Paths with clockwise orientations will be filled in the negative fill rule (away from the camera).
