SbVec3d::SbVec3d ( const double v[3] )

inline

Constructs an SbVec3d instance with initial values from v.

SbVec3d() [3/8]

SbVec3d::SbVec3d ( double x, double y, double z )

inline

Constructs an SbVec3d instance with the initial vector endpoint set to <x,y,z>.

SbVec3d() [4/8]

SbVec3d::SbVec3d ( const SbVec3f & v )

inlineexplicit

Constructs an SbVec3d instance from an SbVec3f instance.

SbVec3d() [5/8]

SbVec3d::SbVec3d ( const SbVec3b & v )

inlineexplicit

Constructs an SbVec3d instance from an SbVec3b instance.

Since

Coin 2.5

SbVec3d() [6/8]

SbVec3d() [8/8]

SbVec3d::SbVec3d	(	const SbDPPlane &	p0,
		const SbDPPlane &	p1,
		const SbDPPlane &	p2 )

Constructs an SbVec3d instance by combining the three given planes. None of the planes should be parallel to any of the other two, otherwise a divide by zero error will occur.
