This module provides the BBox4 type for 4-dimensional bounding boxes (bounding hyper-volumes).



data BBox4 Source

A BBox4 is a 4D bounding box (aligned to the coordinate axies).




minX :: !Scalar
minY :: !Scalar
minZ :: !Scalar
minW :: !Scalar
maxX :: !Scalar
maxY :: !Scalar
maxZ :: !Scalar
maxW :: !Scalar


rangeX :: BBox4 -> RangeSource

Return the X-range that this bounding box covers.

rangeY :: BBox4 -> RangeSource

Return the Y-range that this bounding box covers.

rangeZ :: BBox4 -> RangeSource

Return the Z-range that this bounding box covers.

rangeW :: BBox4 -> RangeSource

Return the W-range (4th coordinate) that this bounding box covers.

rangeXYZW :: Range -> Range -> Range -> Range -> BBox4Source

Given ranges for each coordinate axis, construct a bounding box.

bound_corners :: Vector4 -> Vector4 -> BBox4Source

Given a pair of corner points, construct a bounding box. (The points must be from opposite corners, but it doesn't matter which corners nor which order they are given in.)

bound_points :: [Vector4] -> BBox4Source

Find the bounds of a list of points. (Throws an exception if the list is empty.)

within_bounds :: Vector4 -> BBox4 -> BoolSource

Test whether a given 4D vector is inside this bounding box.

min_point :: BBox4 -> Vector4Source

Return the minimum values for all coordinates.

max_point :: BBox4 -> Vector4Source

Return the maximum values for all coordinates.

union :: BBox4 -> BBox4 -> BBox4Source

Take the union of two bounding boxes. The result is a new bounding box that contains all the points the original boxes contained, plus any extra space between them.

isect :: BBox4 -> BBox4 -> Maybe BBox4Source

Take the intersection of two bounding boxes. If the boxes do not overlap, return Nothing. Otherwise return a new bounding box containing only the points common to both argument boxes.

unions :: [BBox4] -> BBox4Source

Efficiently compute the union of a list of bounding boxes.
