The HOpCreateCuttingPlane class provides support for construction a cutting plane and inserting it into the scene.
HOpCreateCuttingPlane implements two of the mouse button event handlers defined on the base class. In this case, the operator uses the LButtonDown event to begin the cutting plane insertion mechanism, but position info is not used. This provides the basic functionality for viewing cut-away scenes, cross-sections, and slices of models. Upon insertion, the default position of the cutting plane lies parallel to the view plane and intersects the z-value of the scene's centerpoint. The operation consists of the following steps:
More Detailed Description: see event methods.
HOpCreateCuttingPlane::HOpCreateCuttingPlane | ( | HBaseView * | view, |
int | DoRepeat = 0 , |

int | DoCapture = 1 |

) |
Constructs an HOpCreateCuttingPlane object.
view | A pointer to an HBaseView object, |
DoRepeat | An integer denoting whether this is a repeatable operator. This parameter has been deprecated. |
DoCapture | An integer denoting whether the mouse state should be captured, which means that all mouse events should be received after a mousedown, even if it leaves the window. This parameter has been deprecated. |

Creates a new operator which is a copy of the current operator. The user is responsible for deleting the newly created operator.

OnLButtonDown begins the cutting plane insertion mechanism and calculates the center of the scene. The center point's z-value is passed internally to initiate the plane's construction. In addition, the plane is placed in the current selection list and will be highlighted until the left mouse button is released.
hevent | An HEventInfo object containing information about the current event. |

OnLButtonUp ends the operation and removes the cutting plane from the current selection list. The function also deselects every item in the scene upon completion.
