rotate()

template<typename T , precision P>

GLM_FUNC_QUALIFIER detail::tmat3x3<T, P> glm::rotate	(	detail::tmat3x3< T, P > const &	m,
		T const &	angle
	)

Builds a rotation 3 * 3 matrix created from an angle.

Parameters

m	Input matrix multiplied by this translation matrix.
angle	Rotation angle expressed in radians if GLM_FORCE_RADIANS is defined or degrees otherwise.

scale()

template<typename T , precision P>

GLM_FUNC_QUALIFIER detail::tmat3x3<T, P> glm::scale	(	detail::tmat3x3< T, P > const &	m,
		detail::tvec2< T, P > const &	v
	)

Builds a scale 3 * 3 matrix created from a vector of 2 components.

Parameters

m	Input matrix multiplied by this translation matrix.
v	Coordinates of a scale vector.

shearX()

template<typename T , precision P>

GLM_FUNC_QUALIFIER detail::tmat3x3<T, P> glm::shearX	(	detail::tmat3x3< T, P > const &	m,
		T const &	y
	)

x	Shear factor.

translate()

template<typename T , precision P>

GLM_FUNC_QUALIFIER detail::tmat3x3<T, P> glm::translate	(	detail::tmat3x3< T, P > const &	m,
		detail::tvec2< T, P > const &	v
	)
