`z_far`	`float`

private/libs/gltf/math/lv_gltf_math.hpp:44function

lv_gltf_math_euler_to_quaternion

Build a rotation quaternion from Euler angles given in radians. The angles are the rotations around the X, Y and Z axis, in that order.

cpp

template <typename T>
fastgltf::math::quat< T > lv_gltf_math_euler_to_quaternion(T x, T y, T z)

Name	Type
`x`	`T`
`y`	`T`
`z`	`T`

Template Parameters:

Name	Type	Description
`T`	`typename`

private/libs/gltf/math/lv_gltf_math.hpp:66function

lv_gltf_math_quaternion_to_euler

Decompose a rotation quaternion into Euler angles in radians. The result holds the rotations around the X, Y and Z axis, in that order, so that it can be passed back to lv_gltf_math_euler_to_quaternion().

cpp

template <typename T>
fastgltf::math::vec< T, 3 > lv_gltf_math_quaternion_to_euler(fastgltf::math::quat< T > q)

Name	Type
`q`	`fastgltf::math::quat< T >`

Template Parameters:

Name	Type	Description
`T`	`typename`
