Methods in detail

Box3 ( in Box3 other )

copy constructor

Box3 ( in Vec3 min, in Vec3 max )

Constructor from vectors

Box3 ()

Default constructor

Box3 Box3.affineTransform? ( in Mat44 mat44 )

Similar to ‘Box3 * (Mat44 mat44, Box3 b)’, but optimized for affine transforms (SRT)

Vec3 Box3.center? ()

Returns center of this box. Note that this in not valid for an empty box.

Box3 Box3.clone? ()

clone method

Vec3 Box3.diagonal? ()

Returns diagonal (vector from min to max) of this box. Note that this in not valid for an empty box.

Scalar Box3.diameter? ()

Returns the diameter of this box, which is the distance from min to max.

UInt32 Box3.hash? ()

Hash for this value

Boolean Box3.isEmpty? ()

Returns true if this box has no content

Boolean Box3.isInfinite? ()

Returns true if this box is infinite

Box3.merge! ( in Box3 v )

Merges the given box into this box

Box3.merge! ( in Vec3 v )

Merges the given vector into this box

Box3.setEmpty! ()

Setting this box to an empty box

Box3.setInfinite! ()

Setting this box to an infinite box

Operators in detail

Box3 = ( Param other )

Merges another box to this one
