• const vec3 & max - Bounding box maximum coordinates.

BoundBox ( const BoundBox & bb ) #

Initialization by the bounding box.

Arguments

• const BoundBox & bb - Bounding box.

explicit BoundBox ( const BoundSphere & bs ) #

Initialization by the bounding sphere.

Arguments

• const BoundSphere & bs - Bounding sphere.

void set ( const vec3 & min, const vec3 & max ) #

Sets the bounding box by its minimum and maximum coordinates.

Arguments

• const vec3 & min - Bounding box minimum coordinates.
• const vec3 & max - Bounding box maximum coordinates.

void set ( const BoundSphere & bs ) #

Sets the bounding box by the bounding sphere.

Arguments
