Detailed Description
The HOpConstructCone class provides support for constructing a cone and inserting it into the model.
HOpConstructCone implements four of the mouse button event handlers defined on the base class and maps the event information to the local methods that rubberband a cone. This class provides the basic functionality for temporarily drawing a three-dimensional, tesselated cone with a circular base and a number of triangular, facetted sides with the default being 30. The operation consists of the following steps:
- Left Button Down: Registers the center point of the cone base.
- Left Button Down and Drag: Rubberbands the circle to the desired base circumferences
- Left Button Up: The base circumference is finalized.
- No Button Down and Drag: Rubberbands the cone to desired height.
- Left Button Down: The height is finalized, the operation is ended and the primitive is removed from the scene.
More Detailed Description: see event methods.
Constructor & Destructor Documentation
◆ HOpConstructCone()
HOpConstructCone::HOpConstructCone | ( | HBaseView * | view, |
int | DoRepeat = 0 , |
||
int | DoCapture = 1 |
||
) |
Constructs an HOpConstructCone 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.
Member Function Documentation
◆ Clone()
|
virtual |
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 HOpConstructCone object.
Reimplemented from HBaseOperator.
Reimplemented in HOpCreateCone.
◆ ConstructWireframeCone()
|
protected |
ConstructWireframeCone transforms the pointer coordinates from screen to world space and inserts a wireframe cone into the scene. This function is called internally by OnNoButtonDownAndMove after the base dimensions have been finalized.
- Parameters
-
center The center of the circle that forms base of the cone. radius The length of the radius of the cone's base. height The height of the cone.
◆ GetName()
|
virtual |
- Returns
- A pointer to a character string denoting the name of the operator, which is 'HOpConstructCone'.
Reimplemented from HBaseOperator.
Reimplemented in HOpCreateCone.
◆ OnLButtonDown()
|
virtual |
OnLButtonDown records the first pointer position and initiates the cone-drawing mechanism. The first point is used as the center of the cone's circular base. If the drawing mechanism has already been started such as LButtonDown having been called once already, LButtonDown record the last point, calculates the height of the cone, finalizes the operator and then clear the geometry from the scene.
- Parameters
-
hevent An HEventInfo object containing information about the current event.
- Returns
- An HOperatorReturn indicating the status of the event.
Reimplemented from HBaseOperator.
Reimplemented in HOpCreateCone.
◆ OnLButtonDownAndMove()
|
virtual |
OnLButtonDownAndMove draws a rubberbanded line along the circumference of a circle centered on the first pointer position. Note that the basic drawing work is done by HUtility::CreateAxisCircle, while OnLButtonDownAndMove computes and keeps track of the radial vector that defines the base.
- Parameters
-
hevent An HEventInfo object containing information about the current event.
- Returns
- An HOperatorReturn indicating the status of the event.
Reimplemented from HBaseOperator.
◆ OnLButtonUp()
|
virtual |
OnLButtonUp finalizes the size of the base, sets the value of m_RadiusLength and m_radius_world_vector, and cleans up. This function is not called after the second call to OnLButtonDown.
- Parameters
-
hevent An HEventInfo object containing information about the current event.
- Returns
- An HOperatorReturn indicating the status of the event.
Reimplemented from HBaseOperator.
◆ OnNoButtonDownAndMove()
|
virtual |
OnNoButtonDownAndMove draws rubberband lines from the circular base of the cone to the current mouse position.
Note that the basic work is done by internal calls to HOpConstructCone::ConstructWireframeCone.
- Parameters
-
hevent An HEventInfo object containing information about the current event.
- Returns
- An HOperatorReturn indicating the status of the event.
Reimplemented from HBaseOperator.
