Function Documentation

tpt_rotation2quaternion_f32()

void tpt_rotation2quaternion_f32	(	f32_t *	aOutQuater,
		const f32_t *	aInRotation,
		uint32_t	aCount )

Conversion of a rotation matrix to an equivalent quaternion.

Parameters

[out]	aOutQuater	points to an array of quaternions
[in]	aInRotation	points to an array 3x3 rotation matrix (in row order)
[in]	aCount	number of quaternions

Returns

none

Note

q and -q are representing the same rotation. This ambiguity must be taken into account when using the output of this function.
