Constructor & Destructor Documentation

Vector3f::Vector3f ( const Vector3f & v )

inline

Create a new Vector3f copying the coordinates of v.

Parameters

v	is the other vector to copy coordinates.

Vector3f::Vector3f ( const Vector3f * v )

inline

Create a new Vector3f copying the coordinates of v.

Parameters

v	is the other vector to copy coordinates.

Vector3f::Vector3f	(	const GLfloat	_x,
		const GLfloat	_y,
		const GLfloat	_z
	)

inline

Create a Vector3f using the coordinates of parameters.

Parameters

_x	is the coordinate of x.
_y	is the coordinate of y.
_z	is the coordinate of z.

Vector3f::Vector3f ( const GLfloat a[3] )

inline

Create a Vector3f using the coordinates of array a[].

Parameters

a[]	is the array to copy coordinates.

Member Function Documentation

GLvoid Vector3f::copyInto ( GLfloat a[3] )

inline

Copy the array a content in the vector.

Parameters

a[]	is the array to copy coordinates.

Vector3f* Vector3f::cross ( const Vector3f & v )

inline

Compute the cross product of the vector with the vector v.

Parameters

v	the other vector to compute the cross product.

Returns: Vector3f* the cross product.

Here is the call graph for this function:

GLfloat Vector3f::dot ( const Vector3f & v )

inline

Compute the dot product of the vector with the vector v.

Parameters

v	the other vector to compute the dot product.

Returns: GLfloat the dot product.

Vector3f* Vector3f::getOneOrthogonal ( )

inline

Compute one of the orthogonal vectors of the vector.

Returns: Vector3f* an orthogonal vector.

Here is the call graph for this function:

GLboolean Vector3f::isZero ( )

inline

Check if the vector is (0, 0, 0).

Returns: GLboolean true if it is (0, 0, 0), else false.

GLfloat Vector3f::length ( )

inline

Compute the length of the vector.

If you have to check only which vector among others is longer you can use the lengthSq() function that is less resource expensive.

Returns: GLfloat length of the vector.

Here is the call graph for this function:

Here is the caller graph for this function:

GLfloat Vector3f::lengthSq ( )

inline

Compute the length^2 of the vector.

The length^2 is less resource expensive then length(). You can use it for check which vector is longer.
