shz_quat_from_rotation_xyz_u16

Markdown

SHZ_INLINE shz_quat_t shz_quat_from_rotation_xyz_u16(uint16_t xAngle, uint16_t yAngle, uint16_t zAngle) SHZ_NOEXCEPT;

Equivalent to shz_quat_from_rotation_xyz(), with 16-bit binary angles (65536 per turn, the FSCA unit).

Parameters

Name	Type	Description
`xAngle`	`uint16_t`
`yAngle`	`uint16_t`
`zAngle`	`uint16_t`

Returns

shz_quat_t

Details

For games whose orientations are stored as 16-bit angles, such as N64 titles. Signed 16-bit angles can be passed as they are. The half angles go to FSCA directly, without a conversion to radians, so an odd angle is off by half a unit (1/131072 of a turn) in its half angle.

Naming and requirements

u16: Angle is a 16-bit fixed-point value: 0..65535 maps to 0..2π, the native FSCA input format. (Naming and Suffixes)
