Member Function Documentation

Vector2D* sonus::Vector2D::setTo	(	double	x,
		double	y
	)

Sets vector to given double values

Parameters:

	x	x value
	y	y value

Returns:

pointer to vector itself

Vector2D* sonus::Vector2D::setTo

(

double

a[]

)

Sets vector to given array values

Parameters:

a

double array with length of 2

Returns:

pointer to vector itself

Vector2D* sonus::Vector2D::setTo

(

Vector2D *

v

)

Sets vector to given vector pointer values

Parameters:

v

the vector pointer to be copied

Returns:

pointer to vector itself

Vector2D* sonus::Vector2D::setTo

(

Vector2D

v

)

Sets vector to given vector values

Parameters:

v

the vector to be copied

Returns:

pointer to vector itself

Vector2D* sonus::Vector2D::unify

(

)

Unifies the vector. This means the vector is divided by his length, which leaves it with a total length of 1.

Returns:

pointer to vector itself

double sonus::Vector2D::magnitude

(

)

Calculates the magnitude of the vector. Used in unify().

Returns:

magnitude the magnitude

double sonus::Vector2D::dot

(

Vector2D

v

)

Calculates the dot product of self and given vector.

Parameters:

v

the 2nd vector

Returns:

the dot product of the vector itself and the 2nd vector

Vector2D* sonus::Vector2D::transform

(

double

transmatrix[16]

)

Transforms a vector by given transformation matrix. Used by the Haptics module to transform the device workspace to the application workspace.

Parameters:

transmatrix

double array with a length of 16

See also:

sonus::Haptics

Vector2D* sonus::Vector2D::invTransform

(

double

transmatrix[16]

)

Invert transforms a vector by given transformation matrix. Used by the Haptics module to transform the device workspace to the application workspace.

Parameters:

transmatrix

double array with a length of 16

See also:

sonus::Haptics

void sonus::Vector2D::toArray

(

double *

arr

)

Converts the vector to an array.

Parameters:

arr

out parameter: the array the values to be saved in

char* sonus::Vector2D::toString

(

)

[virtual]

Only for testing and debugging.

Returns:

meta string

Reimplemented from sonus::Element2D.

Vector2D* sonus::Vector2D::rotate

(

double

angle

)

Rotates a vector by given angle.

Parameters:

angle

the angle the vector to be rotated

Returns:

the vector itself

Vector2D* sonus::Vector2D::normal

(

)

Calculates the normal vector. In two dimensional space there is only one normal to a vector. The normal is perpendicular to the vector.

Returns:

the normal vector
