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

METHODS

SbSphere()

SbSphere(const SbVec3f &center, float radius)
Constructors.

void
setValue(const SbVec3f &center, float radius)
Change the center and radius.

void
setCenter(const SbVec3f &center)
void
setRadius(float radius)
Set just the center or radius.

const SbVec3f &
getCenter() const
float
getRadius() const
Return the center and radius.

void
circumscribe(const SbBox3f &box)
Return a sphere containing a given box.

SbBool
intersect(const SbLine &l, SbVec3f &intersection) const
SbBool
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.
