Function details

incisionCollisionModel() [1/2]

bool sofa::gui::component::performer::TopologicalChangeManager::incisionCollisionModel	(	sofa::core::CollisionElementIterator	elem,
		sofa::type::Vec3 &	pos,
		bool	firstInput,
		int	snapingValue = 0,
		int	snapingBorderValue = 0
	)

Handles Cutting (activated only for a triangular topology)

Only one model is given. This function perform incision between input point and stocked information. If it is the first point of the incision, these information are stocked. i.e element index and picked point coordinates.

incisionTriangleSetTopology

Parameters

elem	- iterator to collision model.
pos	- picked point coordinates.
firstInput	- bool, if yes this is the first incision point.
snapingValue	- threshold distance from point to incision path where point has to be snap on incision path.
snapingBorderValue	- threshold distance from point to mesh border where incision is considered to reach the border..

Returns

bool - true if incision has been performed.

incisionCollisionModel() [2/2]

bool sofa::gui::component::performer::TopologicalChangeManager::incisionCollisionModel	(	sofa::core::CollisionModel *	model1,
		Index	idx1,
		const sofa::type::Vec3 &	firstPoint,
		sofa::core::CollisionModel *	model2,
		Index	idx2,
		const sofa::type::Vec3 &	secondPoint,
		int	snapingValue = 0,
		int	snapingBorderValue = 0
	)

Handles Cutting for general model collision (activated only for a triangular topology for the moment).

Given two collision model, perform an incision between two points.

Parameters

model1	- first collision model.
idx1	- first element index.
firstPoint	- first picked point coordinates.
model2	- second collision model.
idx2	- second element index.
secondPoint	- second picked point coordinates.
snapingValue	- threshold distance from point to incision path where point has to be snap on incision path.
snapingBorderValue	- threshold distance from point to mesh border where incision is considered to reach the border..

Returns

bool - true if incision has been performed.

setIncisionFirstCut()

void sofa::gui::component::performer::TopologicalChangeManager::setIncisionFirstCut

(

bool

isFirstCut

)

Sets incision starting parameter - incision is just started or already in course

Parameters

isFirstCut

- true if the next incision event will be the first of a new incision
