glm::scale
GLM_FUNC_DECL mat< 4, 4, T, Q > scale(mat< 4, 4, T, Q > const &m, vec< 3, T, Q > const &v)
Builds a scale 4 * 4 matrix created from 3 scalars.
glm::decompose
GLM_FUNC_DECL bool decompose(mat< 4, 4, T, Q > const &modelMatrix, vec< 3, T, Q > &scale, qua< T, Q > &orientation, vec< 3, T, Q > &translation, vec< 3, T, Q > &skew, vec< 4, T, Q > &perspective)
Decomposes a model matrix to translations, rotation and scale components.
glm::orientation
GLM_FUNC_DECL mat< 4, 4, T, Q > orientation(vec< 3, T, Q > const &Normal, vec< 3, T, Q > const &Up)
Build a rotation matrix from a normal and a up vector.
glm::perspective
GLM_FUNC_DECL mat< 4, 4, T, defaultp > perspective(T fovy, T aspect, T near, T far)
Creates a matrix for a symmetric perspective-view frustum based on the default handedness and default...
