root class ; the inheriting classes will be able to give sensitive Areas for the dynamic selection algorithms
Checks whether the sensitive entity matches the picking detection area (close to the picking line). This method takes into account depth limits produced by abstract view: far/near planes, clippings. Please port existing implementations of your picking detection, which were done at Matches (X, Y, Tol, DMin) method to this one, introducing the depth checks. Please note that the previous method is suppressed and the virtual implementations are not used by OCC selection framework. The porting procedure for simple sensitives (or if you are not interested in implementing full scale depth checks) can be simplified to writing the following code snippet:
{
if (!
Matches (thePickArgs.X(), thePickArgs.Y(), thePickArgs.Tolerance(), theMatchDMin))
Standard_Real aDetectDepth = ComputeDepth (thePickArgs.PickLine());
return !thePickArgs.IsClipped(aDetectDepth);
}
- Parameters
-
thePickArgs | [in] the picking arguments. |
theMatchDMin | [out] the minimum distance on xy plane from point of picking to center of gravity of the detected sub-part of sensitive entity or the whole sensitive (e.g. used for resolving selection of coinciding circles, selection will be set to the one whose center is closest to the picking point). |
theMatchDepth | [out] the minimum detected depth: depth of the closest detected sub-part of sensitive entity (or the whole sensitive). |
- Returns
- True if the sensitive matches the detection area. This method is an entry point for picking detection framework. The method is triggered when it is required to compose list of detected sensitive entities. The sensitives are filtered out from detection result if returned value is False. The passed entities are then can be sorted by "theDetectDist", "theDetectDepth" parameters.
Implemented in Select3D_SensitiveGroup, Select3D_SensitiveSegment, Select3D_SensitiveCircle, Select3D_SensitiveTriangulation, Select3D_SensitiveWire, Select3D_SensitiveBox, Select3D_SensitiveCurve, Select3D_SensitiveFace, Select3D_SensitivePoint, MeshVS_SensitivePolyhedron, Select3D_SensitiveTriangle, MeshVS_SensitiveMesh, and MeshVS_DummySensitiveEntity.
