Detailed Description

General purpose double triple for use as vertices, vectors and normals. Provides general math operations from addition through to cross products. No support yet added for double * Vec3d - is it necessary? Need to define a non-member non-friend operator* etc. Vec3d * double is okay

Member Typedef Documentation

typedef double osg::Vec3d::value_type

Data type of vector components.

Member Enumeration Documentation

anonymous enum

Number of vector components.

Enumerator
num_components 

Definition at line 37 of file Vec3d.h.

Constructor & Destructor Documentation

osg::Vec3d::Vec3d ( )
inline

Constructor that sets all components of the vector to zero

Definition at line 42 of file Vec3d.h.

Here is the caller graph for this function:

osg::Vec3d::Vec3d ( const Vec3f &  vec)
inline

Definition at line 44 of file Vec3d.h.

osg::Vec3d::Vec3d ( value_type  x,
value_type  y,
value_type  z 
)
inline

Definition at line 48 of file Vec3d.h.

Here is the call graph for this function:

osg::Vec3d::Vec3d ( const Vec2d &  v2,
value_type  zz 
)
inline

Definition at line 49 of file Vec3d.h.

Member Function Documentation

bool osg::Vec3d::isNaN ( ) const
inline

Returns true if at least one component has value NaN.

Definition at line 96 of file Vec3d.h.

Here is the call graph for this function:

Here is the caller graph for this function:

value_type osg::Vec3d::length ( ) const
inline

Length of the vector = sqrt( vec . vec )

Definition at line 181 of file Vec3d.h.

Here is the caller graph for this function:

value_type osg::Vec3d::length2 ( void  ) const
inline

Length squared of the vector = vec . vec

Definition at line 187 of file Vec3d.h.

value_type osg::Vec3d::normalize ( )
inline

Normalize the vector so that it has length unity. Returns the previous length of the vector. If the vector is zero length, it is left unchanged and zero is returned.

Definition at line 196 of file Vec3d.h.

Here is the call graph for this function:

osg::Vec3d::operator Vec3f ( ) const
inline

Definition at line 46 of file Vec3d.h.

bool osg::Vec3d::operator!= ( const Vec3d &  v) const
inline

Definition at line 58 of file Vec3d.h.

value_type osg::Vec3d::operator* ( const Vec3d &  rhs) const
inline

Dot product.

Definition at line 99 of file Vec3d.h.

const Vec3d osg::Vec3d::operator* ( value_type  rhs) const

Definition at line 143 of file Vec3d.h.

Here is the call graph for this function:

Vec3d& osg::Vec3d::operator+= ( const Vec3d &  rhs)
inline

Unary vector add. Slightly more efficient because no temporary intermediate object.

Definition at line 151 of file Vec3d.h.
