shz_mat4x4_get_scale

SHZ_INLINE shz_vec3_t shz_mat4x4_get_scale(const shz_mat4x4_t* mat) SHZ_NOEXCEPT;

Exracts the 3D scale factors from the given 4x4 matrix.

Parameters

Name	Type	Description
mat	const shz_mat4x4_t *

Returns

shz_vec3_t

Warnings

• This routine assumes mat is a standard TRS-style transform matrix, without shearing or reflection.

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.
