shz_mat4x4_transform_point3

SHZ_INLINE shz_vec3_t shz_mat4x4_transform_point3(const shz_mat4x4_t* mat, shz_vec3_t pt) SHZ_NOEXCEPT;

Transforms a 3D point by a 4x4 matrix.

Parameters

Name	Type	Description
`mat`	`const shz_mat4x4_t *`
`pt`	`shz_vec3_t`

shz_vec3_t

This is a routine specializing in one-off transforms of a single 3D point by a single 4x4 matrix. It should be faster than going through XMTRX.

For batch transforming multiple 3D points against the same 4x4 matrix, preload the matrix into XMTRX, then use shz_xmtrx_transform_point3().

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.
