2.3 DUIM-Geometry Module
region-intersection
Generic function
Summary
Returns the intersection of two regions, as a region.
Signature
region-intersectionregion1 region2 => region
Arguments
- region1
- An instance of type
<region>. - region2
- An instance of type
<region>.
Values
- region
- An instance of type
<region>.

Description
Returns a region that contains all points that are in both of the regions region1 and region2 (possibly with some points removed in order to satisfy the dimensionality rule).
The result of region-intersection has dimensionality that is the minimum dimensionality of region1 and region2, or is $nowhere. For example, the intersection of two areas is either another area or $nowhere; the intersection of two paths is either another path or $nowhere; the intersection of a path and an area produces the path clipped to stay inside of the area.
Note: region-intersection may return either a simple region or a region set.
