Module glm::ext [−] [src]

Functions that extend the functionalities of GLSL data types.

Note

Unlike built-in functions, extension functions are not re-exported to the root module of glm. You have to use glm::ext.
Also unlike the built-in functions, the naming of extension functions follows the Rust convention, instead of the GLSL's. That is, snake case is used.
The parameters of matrix related functions are passed by reference.

angle	Returns angle between vectors `x` and `y`.
cbrt	Returns the cubic root.
is_invertible	Returns `true` if the square matrix `m` is invertible, i.e., its determinant does not close or equal to `0`.
is_perpendicular	Returns `true` if vector `x` is perpendicular to `y`, i.e., angle between `x` and `y` is π/2.
look_at	Build a look at view matrix based on the default handedness.
look_at_rh	Build a right handed look at view matrix.
normalize_to	Normalizes vector `x` of specific length `len`.
perspective	Creates a matrix for a symetric perspective-view frustum based on the default handedness.
perspective_rh	Creates a matrix for a right handed, symetric perspective-view frustum.
pow2	`x * x`.
pow3	`x * x * x`.
powi	Raise a number to an integer power.
projection	Projects `x` on `y`.
recip	Returns the reciprocal (inverse) of float number `x`.
recip_length	Returns the reciprocal (inverse) of the length of vector `x`.
rotate	Builds a rotation 4 * 4 matrix created from an axis vector and an angle.
scale	Builds a scale 4 * 4 matrix created from 3 scalars.
sin_cos	Simultaneously computes the sine and cosine of `x`, returns `(sin(x), cos(x))`.
sqlength	Returns the squre of the length of vector `x`.
trace	Returns the trace of a square matrix `m`.
translate	Builds a translation 4 * 4 matrix created from a vector of 3 components.
