shz_mat4x4_transform_vec4_transpose

Markdown

SHZ_INLINE shz_vec4_t shz_mat4x4_transform_vec4_transpose(const shz_mat4x4_t* m, shz_vec4_t v) SHZ_NOEXCEPT;

Transforms a 4D vector the the transpose of a 4x4 matrix.

Parameters

Name	Type	Description
`m`	`const shz_mat4x4_t *`
`v`	`shz_vec4_t`

Returns

shz_vec4_t

Details

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

Notes

For batch transforming multiple 4D vectors against the transpose of the same 4x4 matrix, preload the matrix into XMTRX, take its transpose with shz_xmtrx_transpose(), then use shz_xmtrx_transform_vec4().

Naming and requirements

_transpose: Operates with the transposed matrix (row-major input, or inverse-rotation use). (Naming and Suffixes)
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.
