Function Documentation

◆ rotate()

GLM_FUNC_QUALIFIER mat<3, 3, T, Q> glm::rotate ( mat< 3, 3, T, Q > const &  m,
angle 
)

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

Parameters
mInput matrix multiplied by this translation matrix.
angleRotation angle expressed in radians.

◆ scale()

GLM_FUNC_QUALIFIER mat<3, 3, T, Q> glm::scale ( mat< 3, 3, T, Q > const &  m,
vec< 2, T, Q > const &  v 
)

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

Parameters
mInput matrix multiplied by this translation matrix.
vCoordinates of a scale vector.

◆ shearX()

GLM_FUNC_QUALIFIER mat<3, 3, T, Q> glm::shearX ( mat< 3, 3, T, Q > const &  m,
y 
)

Builds an horizontal (parallel to the x axis) shear 3 * 3 matrix.

Parameters
mInput matrix multiplied by this translation matrix.
yShear factor.

◆ shearY()

GLM_FUNC_QUALIFIER mat<3, 3, T, Q> glm::shearY ( mat< 3, 3, T, Q > const &  m,
x 
)

Parameters
mInput matrix multiplied by this translation matrix.
xShear factor.

◆ translate()

GLM_FUNC_QUALIFIER mat<3, 3, T, Q> glm::translate ( mat< 3, 3, T, Q > const &  m,
vec< 2, T, Q > const &  v 
)

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

Parameters
mInput matrix multiplied by this translation matrix.
vCoordinates of a translation vector.
