Select3D_SensitiveTriangle (const Handle< SelectBasics_EntityOwner > &OwnerId, const gp_Pnt &P1, const gp_Pnt &P2, const gp_Pnt &P3, const Select3D_TypeOfSensitivity Sensitivity=Select3D_TOS_INTERIOR) | |
Constructs a sensitive triangle object defined by the owner OwnerId, the points P1, P2, P3, and the type of sensitivity Sensitivity. More... | |
Standard_Boolean | Matches (const SelectBasics_PickArgs &thePickArgs, Standard_Real &theMatchDMin, Standard_Real &theMatchDepth) |
Checks whether the sensitive entity matches the picking detection area (close to the picking line). For details please refer to base class declaration. More... | |
virtual Standard_Boolean | Matches (const Standard_Real XMin, const Standard_Real YMin, const Standard_Real XMax, const Standard_Real YMax, const Standard_Real aTol) |
Matches the box defined by the coordinates Xmin, Ymin, Xmax, Ymax with the entity found at that point within the tolerance aTol. Xmin, YMin define the minimum point in the lower left hand corner of the box, and XMax, YMax define the maximum point in the upper right hand corner of the box. You must redefine this function for every inheriting entity. You will have to call this framework inside the redefined function. More... | |
