Syntax
- innerRectangle (alignment) { selector operator operations | selector operator operations }
Parameters
- alignment—keyword
- scope—the largest inner rectangle is found that has sides parallel to the scope's axes.
- edge—the largest inner rectangle is found that has a side parallel to one edge. Per outer polygon/hole, only edges with length greater than quarter the maximum length are considered.
The resulting shape is a rectangle seen from the predominant scope axis of the face normal. The scope's orientation is the same as in the initial shape. - selector —keyword
- shape—the inner rectangle polygon.
- remainder—selects the remainder of the polygon.
- operatorThe operator defines how the inner rectangle polygons are used to generate successor shapes. This also applies to shapes with more than one faces. Valid operators are:
- : Each polygon is put into a new shape.
- = All polygons corresponding to the selector are combined into one new shape.
- operationsA sequence of CGA operations to execute.
Description
The innerRectangle operation finds for each face of the current shape's geometry the largest rectangle which is fully inside the face.
Note:
The face must not have self-intersections.
