std::vector<double> GlsMatrixAffine::Data

(

)

Provides access to the raw column-major matrix data as a one dimensional array in a format suitable for Open GL matrix operations.

double GlsMatrixAffine::Determinant

(

)

Calculates the determinant of the matrix.

Returns

the calculated value of the determinant.

void GlsMatrixAffine::Invert

(

)

Sets this matrix equal to its inverse.

bool GlsMatrixAffine::IsIdentity

(

)

Determines if this matrix is equal to the identity matrix.

The identity matrix is I = [Aij], where Aii = 1 and Aij = 0 for i != j. Thus, for the identity matrix, the terms off the main diagonal are all zero, and the terms on the main diagonal are all one.

Returns

true if the matrix is the identity matrix, false otherwise.

void GlsMatrixAffine::MakeIdentity

(

)

Set this matrix to the identity matrix.

The identity matrix is I = [Aij], where Aii = 1 and Aij = 0 for i != j. Thus, for the identity matrix, the terms off the main diagonal are all zero, and the terms on the main diagonal are all one.

void GlsMatrixAffine::Rotate	(	double	angle,
		Vector &	centerOfRotation,
		Vector &	axis
	)

Perform a rotation transformation around an arbitrary axis using a specified center of rotation, and combine this transformation with the existing matrix data.

Parameters

angle	rotation angle in degrees
centerOfRotation	point to rotate around
axis	arbitray axis of rotation

void GlsMatrixAffine::Scale	(	double	x,
		double	y,
		double	z
	)

Perform a scaling transformation using the origin as the anchor point, and combine this transformation with the existing matrix data.

Parameters

x	scaling factor in the x direction. 1 = 100% (no scaling change)
y	scaling factor in the y direction. 1 = 100% (no scaling change)
z	scaling factor in the z direction. 1 = 100% (no scaling change)

void GlsMatrixAffine::Scale	(	double	x,
		double	y,
		double	z,
		Vector &	anchor
	)

Perform a scaling transformation using an arbitrary anchor point, and combine this transformation with the existing matrix data.

Parameters

x	scaling factor in the x direction. 1 = 100% (no scaling change)
y	scaling factor in the y direction. 1 = 100% (no scaling change)
z	scaling factor in the z direction. 1 = 100% (no scaling change)
anchor	The anchor point for the scaling

void GlsMatrixAffine::Transform

(

Vector &

v

)

Transform the specified vertex using the data in the matrix, i.e.

v = M * v

void GlsMatrixAffine::Translate	(	double	x,
		double	y,
		double	z
	)

Perform a translation, and combine this transformation with the existing matrix data.

Parameters

x	translation in the x direction
y	translation in the y direction
z	translation in the z direction

void GlsMatrixAffine::Translate

(

Vector &

v

)

Perform a translation, and combine this transformation with the existing matrix data.

Parameters

v	containing the translate values
