Detailed Description

Axis-Aligned Bounding Box (AABB) structure.

Represents a 3D bounding box defined by minimum and maximum corner points. Provides methods for transformations, expansion, and merging with other AABBs.

Constructor & Destructor Documentation

AABB() [1/2]

lmgl::scene::AABB::AABB ( )

inline

Default constructor initializing an empty AABB.

Initializes min and max to zero vectors.

AABB() [2/2]

lmgl::scene::AABB::AABB ( const glm::vec3 & min, const glm::vec3 & max )

inline

Parameterized constructor.

Initializes the AABB with specified minimum and maximum corner points.

Parameters

min	Minimum corner point.
max	Maximum corner point.

Member Function Documentation

expand()

void lmgl::scene::AABB::expand

(

const glm::vec3 &

point

)

Expand the AABB to include a point.

Expands the AABB to ensure it contains the specified point.

Parameters

point

Point to include in the AABB.

get_center()

glm::vec3 lmgl::scene::AABB::get_center ( ) const

inline

Get the center point of the AABB.

Calculates and returns the center point of the AABB.

Returns

Center point as a glm::vec3.

get_extents()

glm::vec3 lmgl::scene::AABB::get_extents ( ) const

inline

Get the extents of the AABB.

Calculates and returns the extents (half-size) of the AABB.

Returns

Extents as a glm::vec3.

merge()

void lmgl::scene::AABB::merge

(

const AABB &

other

)

Merge the AABB with another AABB.

Expands the current AABB to include the volume of another AABB.

Parameters

other

The other AABB to merge with.

transform()

AABB lmgl::scene::AABB::transform

(

const glm::mat4 &

matrix

)

const

Transform the AABB with a matrix.

Applies a transformation matrix to the AABB and returns a new transformed AABB.

Parameters

matrix

Transformation matrix.

Returns

Transformed AABB.
