Constructor & Destructor Documentation

  SbVec3d::SbVec3d (void) [inline]
The default constructor does nothing. The vector coordinates will be uninitialized until you do a setValue() call.

  SbVec3d::SbVec3d (const double v[3]) [inline]
Constructs an SbVec3d instance with initial values from v.

  SbVec3d::SbVec3d (double x, double y, double z) [inline]
Constructs an SbVec3d instance with the initial vector endpoint set to <x,y,z>.

  SbVec3d::SbVec3d (const SbVec3f & v) [inline], [explicit]
Constructs an SbVec3d instance from an SbVec3f instance.

  SbVec3d::SbVec3d (const SbVec3b & v) [inline], [explicit]
Constructs an SbVec3d instance from an SbVec3b instance.

2.5

  SbVec3d::SbVec3d (const SbVec3s & v) [inline], [explicit]
Constructs an SbVec3d instance from an SbVec3s instance.

2.5

  SbVec3d::SbVec3d (const SbVec3i32 & v) [inline], [explicit]
Constructs an SbVec3d instance from an SbVec3i32 instance.

2.5

  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.

Member Function Documentation

  SbVec3d & SbVec3d::setValue (const double v[3]) [inline]
