Constructor & Destructor Documentation

Box() [1/2]

Box ( )

inline

Default constructor is an infinite box that contains all space.

Box() [2/2]

Box ( const glm::vec3  p1, const glm::vec3  p2  )

inline

Creates a box that contains the two given points.

Member Function Documentation

Size()

glm::vec3 Size ( ) const

inline

Returns the dimensions of the Box.

Center()

glm::vec3 Center ( ) const

inline

Returns the center point of the Box.

Scale()

float Scale ( ) const

inline

Returns the absolute-largest coordinate value of any contained point.

Contains() [1/2]

bool Contains ( const glm::vec3 &  p ) const

inline

Does this box contain (includes equal) the given point?

Contains() [2/2]

bool Contains ( const Box &  box ) const

inline

Does this box contain (includes equal) the given box?

Union() [1/2]

void Union ( const glm::vec3  p )

inline

Expand this box to include the given point.

Union() [2/2]

Box Union ( const Box &  box ) const

inline

Expand this box to include the given box.

Transform()

Box Transform ( const glm::mat4x3 &  transform ) const

inline

Transform the given box by the given axis-aligned affine transform.

Ensure the transform passed in is axis-aligned (rotations are all multiples of 90 degrees), or else the resulting bounding box will no longer bound properly.

operator+()

Box operator+ ( glm::vec3  shift ) const

inline

Shift this box by the given vector.

operator+=()

Box & operator+= ( glm::vec3  shift )

inline

Shift this box in-place by the given vector.

operator*()

Box operator* ( glm::vec3  scale ) const

inline

Scale this box by the given vector.

operator*=()

Box & operator*= ( glm::vec3  scale )

inline

Scale this box in-place by the given vector.

DoesOverlap() [1/2]

bool DoesOverlap ( const Box &  box ) const

inline

Does this box overlap the one given (including equality)?

DoesOverlap() [2/2]

bool DoesOverlap ( glm::vec3  p ) const

inline

Does the given point project within the XY extent of this box (including equality)?

IsFinite()

bool IsFinite ( ) const

inline

Does this box have finite bounds?
