BoundBox ( ) #

Constructor. Creates an empty bounding box.

BoundBox ( Variable v ) #

Constructor. Creates a bounding box initialized by one of the following:

• BoundBox - the bounding box.
• BoundSphere - the bounding sphere.

Arguments

• Variable v - Variable of one of the following types:
  • BoundBox bb - The bounding box.
  • BoundSphere bs - The bounding sphere.

BoundBox ( Variable v1, Variable v2 ) #

Constructor. Creates a bounding box initialized by one of the following:

• vec3 and vec3 - minimum and maximum coordinates of the bounding box respectively.
• BoundBox and mat4 - the bounding box and its transformation matrix.

Arguments

• Variable v1 - Argument of one of the following types:
  • vec3 min - Bounding box minimum coordinates.
  • BoundBox bb - The bounding box.
• Variable v2 - Argument of one of the following types:
  • vec3 max - Bounding box maximum coordinates.
  • mat4 transform - Transformation matrix.

const vec3 & getMax ( ) # const

Returns the maximum coordinates of the bounding box.

Return value

Bounding box maximum coordinates.

const vec3 & getMin ( ) # const

Returns the minimum coordinates of the bounding box.

Return value

Bounding box minimum coordinates.

int isValid ( ) # const

Checks the bounding box status.

Return value

1 if the bounding box minimum and maximum coordinates are valid; otherwise, 0.

void clear ( ) #

Clears the bounding box.

void expand ( Variable v ) #

Expands the current bounding box for including given bounding object (box, sphere, frustum).

Arguments

• Variable v - Variable of one of the following types:
  • BoundBox bb - The bounding box.
  • BoundSphere bs - The bounding sphere.
