Detailed Description

template<typename T>
class UT_OBBoxT< T >

Arbitrarily Oriented Bounding (OBB)

Definition at line 58 of file GU_Detail.h.

Constructor & Destructor Documentation

template<typename T>

UT_OBBoxT< T >::UT_OBBoxT

(

)

template<typename T>

UT_OBBoxT< T >::UT_OBBoxT	(	const UT_Matrix4T< T > &	transform,
		const UT_Vector3T< T > &	radii
	)

Construct the OBB from a transform and radii.

template<typename T>

UT_OBBoxT< T >::UT_OBBoxT	(	const UT_Array< UT_Vector3T< T > > &	points,
		int	refinement = 6
	)

Construct the OBB from a set of points.

template<typename T>

UT_OBBoxT< T >::UT_OBBoxT	(	const UT_Vector3T< T > &	position,
		const UT_Vector3T< T > &	size,
		const UT_QuaternionT< T > &	orientation,
		const UT_Vector3T< T > &	pivot = UT_Vector3T< T >((T) 0)
	)

Construct the OBB using the instancing parameters. Note that size is the full size in this case–not radii or half-sizes!
