WorldBoundBox ( ) #

Default constructor. Creates an empty bounding box.

WorldBoundBox ( const dvec3 & min, const dvec3 & max ) #

Constructor. Initializes new bounding box by minimum and maximum coordinates of the bounding box.

Arguments

• const dvec3 & min - The bounding box minimum coordinates.
• const dvec3 & max - The bounding box maximum coordinates.

WorldBoundBox ( const WorldBoundBox & bb ) #

Constructor. Initializes new bounding box by using given bounding box.

Arguments

• const WorldBoundBox & bb - Bounding box.

WorldBoundBox ( const WorldBoundSphere & bs ) #

Constructor. Initializes new bounding box by the using given bounding sphere.

Arguments

• const WorldBoundSphere & bs - Bounding sphere.

void set ( const dvec3 & min, const dvec3 & max ) #

Sets the bounding box by its minimum and maximum coordinates.

Arguments

• const dvec3 & min - The bounding box minimum coordinates.
• const dvec3 & max - The bounding box maximum coordinates.

void set ( const WorldBoundSphere & bs ) #

Sets the bounding box by the bounding sphere.

Arguments

• const WorldBoundSphere & bs - The bounding sphere.

void set ( const WorldBoundBox & bb ) #

Sets the bounding box.

Arguments

• const WorldBoundBox & bb - The bounding box.

const dvec3 & getMax ( ) #

Gets the maximum coordinates of the bounding box.

Return value

The bounding box maximum coordinates.

const dvec3 & getMin ( ) #

Gets the minimum coordinates of the bounding box.

Return value

The bounding box minimum coordinates.

int isValid ( ) #

Checks if the bounding box coordinates are valid (minimum coordinate along the X axis is less or equal to the maximum coordinate along the X axis).

Return value

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

void clear ( ) #

Clears the bounding box.

void expand ( const WorldBoundSphere & bs ) #

Expands the current bounding box for including given bounding sphere.

Arguments

• const WorldBoundSphere & bs - The bounding sphere.

void expand ( const WorldBoundBox & bb ) #

Arguments

• const WorldBoundBox & bb - The bounding box.

void expand ( const dvec3 & point ) #

Expands the current bounding box for including given point.

Arguments

• const dvec3 & point

int inside ( const WorldBoundBox & bb ) #

Checks if the bounding box is inside the bounding box.

Arguments

• const WorldBoundBox & bb - The bounding box.

Return value

1 if the bounding box is inside the bounding box; otherwise, 0.

int inside ( const dvec3 & min, const dvec3 & max ) #

Checks if the box is inside the bounding box.

Arguments

• const dvec3 & min - The box minimum coordinates.
• const dvec3 & max - The box maximum coordinates.

Return value

int inside ( const dvec3 & point, double radius ) #

Checks if the sphere is inside the bounding box.

Arguments

• const dvec3 & point - The coordinates of the center of the sphere.
• double radius - The sphere radius.

Return value

1 if the sphere is inside the bounding box; otherwise, 0.

int insideAll ( const WorldBoundBox & bb ) #

Checks if the whole given bounding box is inside the current bounding box.

Arguments

• const WorldBoundBox & bb - The bounding box.

Return value

1 if the whole box is inside the bounding box; otherwise, 0.

int insideAll ( const WorldBoundSphere & bs ) #

Checks if the whole given bounding sphere is inside the current bounding box.

Arguments
