Detailed Description

Bounding sphere data structure in three dimensions.

Constructor & Destructor Documentation

mitsuba::BSphere::BSphere ( )

inline

Construct a bounding sphere at the origin having radius zero.

mitsuba::BSphere::BSphere ( Stream *  stream )

inline

Unserialize a bounding sphere from a binary data stream.

mitsuba::BSphere::BSphere ( const Point &  center, Float  radius  )

inline

Create a bounding sphere from a given center point and radius.

mitsuba::BSphere::BSphere ( const BSphere &  boundingSphere )

inline

Copy constructor.

Member Function Documentation

bool mitsuba::BSphere::contains ( const Point  p ) const

inline

Check whether the specified point is inside or on the sphere.

void mitsuba::BSphere::expandBy ( const Point  p )

inline

Expand the bounding sphere radius to contain another point.

bool mitsuba::BSphere::isEmpty ( ) const

inline

Return whether this bounding sphere has a radius of zero or less.

bool mitsuba::BSphere::operator!= ( const BSphere &  boundingSphere ) const

inline

Inequality test.

bool mitsuba::BSphere::operator== ( const BSphere &  boundingSphere ) const

inline

Equality test.

bool mitsuba::BSphere::rayIntersect ( const Ray &  ray, Float &  nearHit, Float &  farHit  ) const

inline

Calculate the intersection points with the given ray.

Returns

true if the ray intersects the bounding sphere

Remarks

In the Python bindings, this function returns the nearT and farT values as a tuple (or None, when no intersection was found)

void mitsuba::BSphere::serialize ( Stream *  stream ) const

inline

Serialize this bounding sphere to a binary data stream.

std::string mitsuba::BSphere::toString ( ) const

inline

Return a string representation of the bounding sphere.
