INHERITS FROM

SbSphere

SYNOPSIS

#include <Inventor/SbLinear.h>

Methods from class SbSphere:

SbSphere()

SbSphere(const SbVec3f &center, float radius)

void setValue(const SbVec3f &center, float radius)

void setCenter(const SbVec3f &center)

void setRadius(float radius)

const SbVec3f & getCenter() const

float getRadius() const

void circumscribe(const SbBox3f &box)

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

SbBool intersect(const SbLine &l, SbVec3f &enter, SbVec3f &exit) const

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.
