Function Documentation

checkHitSingle3DObject()

bool checkHitSingle3DObject	(	const basegfx::B2DPoint &	rPoint,
		const E3dCompoundObject &	rCandidate
	)

support for checking if the single given 3d object is hit at position

Parameters

rPoint	2D Point in view coordinates
rCandidate	The 3D Object which needs checking

Returns

true if hit, false if not

fillViewInformation3DForCompoundObject()

E3dScene * fillViewInformation3DForCompoundObject	(	drawinglayer::geometry::ViewInformation3D &	o_rViewInformation3D,
		const E3dCompoundObject &	rCandidate
	)

support for getting a ViewInformation3D for a given CompoudObject3D with correct ObjectTransformation filled out

Parameters

o_rViewInformation3D	The ViewInformation3D created which will be overwritten
rCandidate	The E3dCompoundObject for which the ViewInformation3D shall be prepared

Returns

A pointer to the found and used root scene. This is also a hint if the operation succeeded or not, since when object has no root scene (is not inserted to a model), an empty ViewInformation3D will be used

getAllHit3DObjectsSortedFrontToBack()

SVXCORE_DLLPUBLIC void getAllHit3DObjectsSortedFrontToBack	(	const basegfx::B2DPoint &	rPoint,
		const E3dScene &	rScene,
		::std::vector< const E3dCompoundObject * > &	o_rResult
	)

support for getting all from a 2d position hit objects in a 3d scene in a depth sorted array

Parameters

rPoint	2D Point in view coordinates
rScene	The 3D Scene for HitTest
o_rResult	Output parameter which contains all hit 3D objects inside rScene. This vector will be changed in any case. If it's empty, no hit exists. If it's not empty, the first object is the object closest to the viewer
