Detailed Description

Class for representing a sphere.

Represents a sphere in 3D. This is a lightweight datatype that is used for arguments or return values in the Open Inventor toolkit. See SoSphere for a database sphere (used for rendering, picking, etc.).

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

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

The line is treated as a ray.

intersect() [2/2]

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.

setCenter()

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.
