Detailed Description

template<class T>
struct tgt::Matrix3< T >

Matrix3 class.

Works basicly like the matrix stuff in GLSL. But remember that this is a ROW-MATRIX and NOT a COL-MATRIX like in OpenGL or GLSL respectively.

Member Function Documentation

TGT_IMPLEMENT_OPERATORS TGT_IMPLEMENT_MAT_FUNCTIONS Matrix3< T > createRotation	(	T	angle,
		Vector3< T >	axis
	)			[inline, static]

Simliar to glRotate but angle is in RADIAN AND NOT DEGREE.

Parameters:

	angle	The angle in radian.
	axis	The axis of rotation. Needn't be in unit length.

Definition at line 963 of file matrix.h.

static Matrix3<T> createRotationX

(

T

angle

)

[inline, static]

Rotation the x-axis as rotation axis.

The angle is in RADIAN AND NOT DEGREE.

Parameters:

angle

The angle of rotation in radian.

Definition at line 299 of file matrix.h.

static Matrix3<T> createRotationY

(

T

angle

)

[inline, static]

Rotation the y-axis as rotation axis.

The angle is in RADIAN AND NOT DEGREE.

Parameters:

angle

The angle of rotation in radian.

Definition at line 314 of file matrix.h.

static Matrix3<T> createRotationZ

(

T

angle

)

[inline, static]

Rotation the z-axis as rotation axis.

The angle is in RADIAN AND NOT DEGREE.

Parameters:

angle

The angle of rotation in radian.

Definition at line 329 of file matrix.h.

Vector3<T>& operator[]

(

size_t

i

)

[inline]

return arbitrary row-vector similar to GLSL.

BUT REMEMBER: GLSL gives you COLS NOT ROWS!

Definition at line 362 of file matrix.h.

const Vector3<T>& operator[]

(

size_t

i

)

const [inline]

return arbitrary row-vector similar to GLSL.

BUT REMEMBER: GLSL gives you COLS NOT ROWS!
