Function Documentation

iuf3DAngleCompare()

int iuf3DAngleCompare	(	iu3da_t	reference,
		iu3da_t	actual
	)

Compare two 3D angles, the order of arguments does not matter.

Returns

returns IUF_TRUE in case the angles are equal or IUF_FALSE in case they differ.

Parameters

reference	a 3D angle to compare
actual	a 3D angle to compare with

iuf3DAngleCreate()

iu3da_t iuf3DAngleCreate	(	float	theta,
		float	phi
	)

create a 2-axis rotation in 3D space

Returns

returns an allocated and initialized 3D angle

Parameters

theta	the rotation over the y-axis in radians
phi	the rotation over the x-axis in radians

iuf3DAngleDelete()

int iuf3DAngleDelete

(

iu3da_t

angle

)

Delete a 3D angle.

Returns

returns IUF_ERR_VALUE in case this fails or IUF_E_OK in case of success

Parameters

angle

the angle to be removed
