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 WorldBoundBox class. It includes the same functions as the BoundBox class, but its functions deal with the double precision coordinates.

BoundBox()

Constructor. Creates an empty bounding box.

BoundBox(vec3 min, vec3 max)

Initialization by minimum and maximum coordinates of the bounding box.

Arguments

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

BoundBox(BoundBox bb)

Initialization by the bounding box.

Arguments

• BoundBox bb - The bounding box.

explicit BoundBox(BoundSphere bs)

Initialization by the bounding sphere.

Arguments

• BoundSphere bs - The bounding sphere.

void set(vec3 min, vec3 max)

Sets the bounding box by its minimum and maximum coordinates.

Arguments

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

void set(BoundSphere bs)

Sets the bounding box by the bounding sphere.

Arguments

• BoundSphere bs - The bounding sphere.

void set(BoundBox bb)

Sets the bounding box.

Arguments

• BoundBox bb - The bounding box.

vec3 getMax() const

Returns the maximum coordinates of the bounding box.

Return value

The bounding box maximum coordinates.

vec3 getMin() const

Returns the minimum coordinates of the bounding box.

Return value

The 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.

int inside(vec3 point, float radius) const

Checks if the sphere is inside the bounding box.

Arguments

• vec3 point - The coordinates of the center of the sphere.
• float radius - The sphere radius.

Return value

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

int inside(vec3 min, vec3 max) const

Checks if the box is inside the bounding box.

Arguments

• vec3 min - The box minimum coordinates.
• vec3 max - The box maximum coordinates.

Return value

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

int inside(BoundSphere bs) const

Checks if the bounding sphere is inside the bounding box.

Arguments

• BoundSphere bs - The bounding sphere.

Return value

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

int inside(BoundBox bb) const

Checks if the bounding box is inside the bounding box.

Arguments

• BoundBox bb - The bounding box.

Return value

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