data BBox3 Source

A BBox3 is a 3D bounding box (aligned to the coordinate axies).

Instances

Eq BBox3
Show BBox3

rangeX :: BBox3 -> Range Source

Return the X-range that this bounding box covers.

rangeY :: BBox3 -> Range Source

Return the Y-range that this bounding box covers.

rangeZ :: BBox3 -> Range Source

Return the Z-range that this bounding box covers.

rangeXYZ :: Range -> Range -> Range -> BBox3 Source

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

bound_corners :: Vector3 -> Vector3 -> BBox3 Source

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 :: [Vector3] -> BBox3 Source

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

within_bounds :: Vector3 -> BBox3 -> Bool Source

Test whether a given 3D vector is inside this bounding box.

min_point :: BBox3 -> Vector3 Source

Return the minimum values for all coordinates.

max_point :: BBox3 -> Vector3 Source

Return the maximum values for all coordinates.

union :: BBox3 -> BBox3 -> BBox3 Source

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 :: BBox3 -> BBox3 -> Maybe BBox3 Source

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 :: [BBox3] -> BBox3 Source

Efficiently compute the union of a list of bounding boxes.
