Member Function Documentation

void SbSphere::circumscribe

(

const SbBox3f &

box

)

Return a sphere containing a given box.

const SbVec3f& SbSphere::getCenter

(

)

const [inline]

Return the center.

float SbSphere::getRadius

(

)

const [inline]

Return the radius.

SbBool SbSphere::intersect	(	const SbLine &	l,
		SbVec3f &	enter,
		SbVec3f &	exit
	)			const

Intersect line and sphere, returning TRUE if there is an intersection.

The line is treated as a ray.

SbBool SbSphere::intersect	(	const SbLine &	l,
		SbVec3f &	intersection
	)			const

Intersect line and sphere, returning TRUE if there is an intersection.

The line is treated as a ray.

void SbSphere::setCenter

(

const SbVec3f &

c

)

Set the center.

void SbSphere::setRadius

(

float

r

)

Set the radius.

void SbSphere::setValue	(	const SbVec3f &	c,
		float	r
	)

Change the center and radius.
