Unigine::BoundBox Class

This class serves to construct the bounding box in single precision coordinates.

In case of double precision coordinates, the bounding box should be constructed by using the WorldBoundBoxclass. It includes the same functions as theBoundBox class, but its functions deal with the double precision coordinates.

BoundBox()

Constructor. Creates an empty bounding box.

BoundBox(const vec3 & min, const vec3 & max)

Initialization by minimum and maximum coordinates of the bounding box.

Arguments

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

BoundBox(const BoundBox & bb)

Initialization by the bounding box.

Arguments

• const BoundBox & bb - The bounding box.

explicit BoundBox(const BoundSphere & bs)

Initialization by the bounding sphere.

Arguments

• const BoundSphere & bs - The bounding sphere.

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

Sets the bounding box by its minimum and maximum coordinates.

Arguments
