ezSimdBSphere Class Reference

Public Member Functions
	EZ_DECLARE_POD_TYPE ()
	ezSimdBSphere ()
	Default constructor does not initialize any data.
	ezSimdBSphere (const ezSimdVec4f &vCenter, const ezSimdFloat &fRadius)
	Creates a sphere with the given radius around the given center.
void	SetInvalid ()
	Sets the bounding sphere to invalid values.
bool	IsValid () const
	Returns whether the sphere has valid values.
bool	IsNaN () const
	Returns whether any value is NaN.
ezSimdVec4f	GetCenter () const
	Returns the center.
ezSimdFloat	GetRadius () const
	Returns the radius.
void	SetFromPoints (const ezSimdVec4f *pPoints, ezUInt32 uiNumPoints, ezUInt32 uiStride=sizeof(ezSimdVec4f))
	Initializes the sphere to be the bounding sphere of all the given points.
void	ExpandToInclude (const ezSimdVec4f &vPoint)
	Increases the sphere's radius to include this point.
void	ExpandToInclude (const ezSimdVec4f *pPoints, ezUInt32 uiNumPoints, ezUInt32 uiStride=sizeof(ezSimdVec4f))
	Increases the sphere's radius to include all given points. Does NOT change its position, thus the resulting sphere might be not a very tight fit. More efficient than calling this for every point individually.
void	ExpandToInclude (const ezSimdBSphere &rhs)
	Increases this sphere's radius, such that it encloses the other sphere.
void	Transform (const ezSimdTransform &t)
	Transforms the sphere in its local space.
void	Transform (const ezSimdMat4f &mMat)
	Transforms the sphere in its local space.
ezSimdFloat	GetDistanceTo (const ezSimdVec4f &vPoint) const
	Computes the distance of the point to the sphere's surface. Returns negative values for points inside the sphere.
ezSimdFloat	GetDistanceTo (const ezSimdBSphere &rhs) const
	Returns the distance between the two spheres. Zero for spheres that are exactly touching each other, negative values for overlapping spheres.
bool	Contains (const ezSimdVec4f &vPoint) const
	Returns true if the given point is inside the sphere.
bool	Contains (const ezSimdBSphere &rhs) const
	Returns whether the other sphere is completely inside this sphere.
bool	Overlaps (const ezSimdBSphere &rhs) const
	Checks whether the two objects overlap.
ezSimdVec4f	GetClampedPoint (const ezSimdVec4f &vPoint)
	Clamps the given position to the volume of the sphere. The resulting point will always be inside the sphere, but have the closest distance to the original point.
bool	operator== (const ezSimdBSphere &rhs) const
bool	operator!= (const ezSimdBSphere &rhs) const

Member Function Documentation

MakeFromPoints()

ezSimdBSphere ezSimdBSphere::MakeFromPoints ( const ezSimdVec4f *  pPoints, ezUInt32  uiNumPoints, ezUInt32  uiStride = sizeof(ezSimdVec4f)  )

inlinestatic

Creates a bounding sphere around the provided points.

The center of the sphere will be at the 'center of mass' of all the points, and the radius will be the distance to the farthest point from there.

MakeInvalid()

EZ_ALWAYS_INLINE ezSimdBSphere ezSimdBSphere::MakeInvalid ( const ezSimdVec4f &  vCenter = ezSimdVec4f::MakeZero() )

static

Creates an 'invalid' sphere, with its center at the given position and a negative radius.

Such a sphere can be made 'valid' through ExpandToInclude(), but be aware that the originally provided center position will always be part of the sphere.
