Set the center.

circumscribe

public void circumscribe(SbBox3f box)

Return a sphere containing a given box.

intersectFirst

public SbVec3f intersectFirst(SbLine l)

Intersect line and sphere, returning true if there is an intersection. The line is treated as a ray.

getCenter

public SbVec3f getCenter()

Return the center.

getRadius

public float getRadius()

Return the radius.
