SbSphere(3IV)NAMESbSphere (SbSph) - class for representing a sphere
INHERITS FROMSbSphereSYNOPSIS
#include <Inventor_c/SbLinear.h>
typedef SbSphere SbSph
Functions from class SbSphere:
void SbSphCircumscribe(SbSph *this, const SbBox3f *box)
SbBool SbSphIntersect(const SbSph *this, const SbLine *l,
SbVec3f *intersection)
SbBool SbSphIntersect2(const SbSph *this, const SbLine *l,
SbVec3f *enter, SbVec3f *exit)
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.). Note that there
are no Create and Delete functions for SbSphere . C programmers should
treat spheres as standard C structs (declare them locally or use malloc()
):
/* This is defined in Inventor_c/SbLinear.h: */
struct {
struct SbVec3f center;
float radius;
}
/* Your code should look something like this: */
#include <Inventor_c/SbLinear.h>
SbSphere s;
s.radius = 5.0;
SbV3fSetX_Y_Z( s.center, 0.0, 2.0, 0.0 );
FUNCTIONS
void SbSphCircumscribe(SbSph *this, const SbBox3f *box)
Return a sphere containing a given box.

SbBool SbSphIntersect(const SbSph *this, const SbLine *l,
SbVec3f *intersection)
SbBool SbSphIntersect2(const SbSph *this, const SbLine *l,
SbVec3f *enter, SbVec3f *exit)
Intersect line and sphere, returning TRUE if there is an
intersection. The line is treated as a ray.
