BBox Class

Defined in: ../src/geo.js:702

BBox is a class to create BoundingBoxes but it works as glMatrix, creating Float32Array with the info inside instead of objects The bounding box is stored as center,halfsize,min,max,radius (total of 13 floats)

Methods

clone

() BBox

Defined in ../src/geo.js:728

create an bbox copy from another one

Returns:

BBox:

returns a float32array with the bbox

copy

(
  • out
  • where
)
BBox

Defined in ../src/geo.js:738

copy one bbox into another

Parameters:

  • out BBox

    where to store the result

  • where BBox

    to read the bbox

Returns:

BBox:

returns out
