Member Function Documentation

◆ circumscribe()

void SbSphere::circumscribe ( const SbBox3f box)

Return a sphere containing a given box.

◆ getCenter()

const SbVec3f & SbSphere::getCenter ( ) const
inline

Return the center.

Definition at line 87 of file SbSphere.h.

◆ getRadius()

float SbSphere::getRadius ( ) const
inline

Return the radius.

Definition at line 91 of file SbSphere.h.

◆ intersect() [1/2]

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

void SbSphere::setCenter ( const SbVec3f c)

Set the center.

◆ setRadius()

void SbSphere::setRadius ( float  r)

Set the radius.

◆ setValue()

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

Change the center and radius.
