shz_mat4x4_apply_rotation

SHZ_INLINE void shz_mat4x4_apply_rotation(shz_mat4x4_t* mat, float angle, float xAxis, float yAxis, float zAxis) SHZ_NOEXCEPT;

Rotates the given transform matrix about the arbitrary axis given by a 3D direction vector and angle of rotation in radians.

Parameters

Name	Type	Description
mat	shz_mat4x4_t *
angle	float
xAxis	float
yAxis	float
zAxis	float

Returns

Nothing (void).

Details

Multiplies and accumulates the given matrix with the 3D rotation matrix formed from the intrinsic rotation created by the given Tait-Bryan Z-Y-X angles.

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.
