Detailed Description

class
HOpCreateSphere
: public HOpConstructSphere The HOpCreateSphere class provides support for constructing a sphere and inserting it into the model.
HOpCreateSphere uses event information to draw a sphere. This class provides the basic functionality for drawing a three-dimensional, tesselated sphere. The operation consists of the following steps:
- Left Button Down: Registers the center point of the sphere.
- Left Button Down and Drag: Rubberbands the sphere to the desired circumference.
- Left Button Up: Circumference is finalized, clears the scene and inserts a sphere into the HOOPS data base. The operation ends.

HOpCreateSphere
(HBaseView *view, int DoRepeat = 0, int DoCapture = 1) Constructs an HOpCreateSphere object.
Parameters: - 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.

virtual char const *
GetName
() Returns: A pointer to a character string denoting the name of the operator, which is ‘HOpCreateSphere’.
-
virtual int
OnLButtonUp
(HEventInfo &hevent) OnLButtonUp finalizes the size of the sphere and inserts that sphere into the HOOPS database as a shell. Note that most of the work in this function is done by a call to the public function HUtilityGeometryCreation::CreateSphere.
Parameters: hevent – An HEventInfo object containing information about the current event. Returns: An HOperatorReturn indicating the status of the event.
-
virtual HBaseOperator *
Clone
() Creates a new operator which is a copy of the current operator. The user is responsible for deleting the newly created operator.
Returns: A pointer to the newly created HOpCreateSphere object.
