BoundedRegionQ

BoundedRegionQ[reg]

gives True if reg is a bounded region and False otherwise.

Details

  • A region is bounded if it can be included in a box with finite ranges.

Examples

Create a definition that only applies to bounded regions:

Find an enclosing Sphere for a region:

Compute bounds:

Compute enclosing sphere:

Visualize it:

Properties & Relations  (5)

RegionIntersection is bounded if at least one region is BoundedRegionQ:

Since there is one bounded region, the intersection is bounded:

TransformedRegion will be bounded if the regions and transformation are bounded:

Since the transformation is bounded, the resulting region is bounded:

RegionBounds finds a bounding box that includes the region:

The bounds are finite for a bounded region:

The bounds are infinite for an unbounded region:

The RegionMeasure of a bounded region is finite:

The RegionMeasure of an unbounded region is infinite:

The RegionCentroid of a bounded region is finite:

The RegionCentroid of an unbounded region is Indeterminate:
