shz_mat4x4_decompose

void shz_mat4x4_decompose(const shz_mat4x4_t* mat, shz_vec3_t* translation, shz_quat_t* rotation, shz_vec3_t* scale) SHZ_NOEXCEPT;

Decomposes a 4x4 transform matrix into translation, rotation, and scale.

Parameters

Name	Type	Description
mat	const shz_mat4x4_t *
translation	shz_vec3_t *
rotation	shz_quat_t *
scale	shz_vec3_t *

Returns

Nothing (void).

Notes

• Any output pointer may be NULL to skip that component.

Warnings

• This routine clobbers XMTRX.

Naming and requirements

• shz_mat4x4_t and shz_mat2x2_t arguments must be 8-byte aligned. Unaligned data goes through the float[16] parameters of the _unaligned routines.
