SkPoint3 SkPoint3::cross ( const SkPoint3 &  vec) const
inline

◆ CrossProduct()

static SkPoint3 SkPoint3::CrossProduct ( const SkPoint3 &  a,
const SkPoint3 &  b 
)
inlinestatic

Returns the cross product of a and b, treating them as 3D vectors.

◆ dot()

inline

◆ DotProduct()

static SkScalar SkPoint3::DotProduct ( const SkPoint3 &  a,
const SkPoint3 &  b 
)
inlinestatic

Returns the dot product of a and b, treating them as 3D vectors.

◆ isFinite()

bool SkPoint3::isFinite ( ) const
inline

Returns true if fX, fY, and fZ are measurable values.

Returns
true for values other than infinities and NaN

◆ length()

SkScalar SkPoint3::length ( ) const
inline

Return the Euclidian distance from (0,0,0) to the point.

◆ Length()

static SkScalar SkPoint3::Length ( SkScalar  x,
SkScalar  y,
SkScalar  z 
)
static

Returns the Euclidian distance from (0,0,0) to (x,y,z)

◆ Make()

static SkPoint3 SkPoint3::Make ( SkScalar  x,
SkScalar  y,
SkScalar  z

void SkPoint3::operator-= ( const SkPoint3 &  v)
inline

Subtract v's coordinates from the point's.

◆ scale()

void SkPoint3::scale ( SkScalar  value)
inline
