Detailed Description
The HOpCreateNurbs3D class provides support for the interactive construction of various surface types.
HOpCreateNurbs3D implements three of the mouse event handlers defined on the base class to allow the user to interactively modify a nurbs surface by dragging it's control points with the mouse.
The operation consists of the following steps:
- Left Button Down: The operation is initiated and control point for dragging is specified.
- Left Button Down and Drag: The control point moves with mouse position and the surface is recalculated.
- Left Button Up: The surface editing is finalized.
More Detailed Description: see event methods.

◆ HOpCreateNurbs3D()
HOpCreateNurbs3D::HOpCreateNurbs3D | ( | HBaseView * | view, |
int | DoRepeat = 0 , |
||
int | DoCapture = 1 |
||
) |
Constructs an HOpCreateNurbs3D 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 HOpCreateNurbs3D object.
Reimplemented from HBaseOperator.
◆ EmitFinishNurbsEditing()
|
static |
This method emits the finalized Nurbs editing message to other clients.
- Parameters
-
pView A pointer to the current view object. key The surface key. emit_message Indicates that a message should be sent to the emit_message_function
◆ EmitModifyControlPointMessage()
|
static |
This method sends a modify control point message to other clients.
- Parameters
-
pView A pointer to the current view object. key The surface key. control_point The number identifying the manipulated control point of surface. x The new control point x position. y The new control point y position. z The new control point z position.
◆ FinishNurbsEditingFromMessage()
|
static |
This method receives the Finish Nurbs editing message.
- Parameters
-
in_data A character pointer indicating the end of surface editing. data_length The size of the message. pView A pointer to the current view object.
Referenced by HNurbsMessageHandler::ProcessMessage().
◆ GetName()
|
virtual |
- Returns
- A pointer to a character string denoting the name of the operator which is 'HOpCreateNurbs3D'.
Reimplemented from HBaseOperator.
◆ InsertNurbs()
|
static |
This method insert the given surface into the scene.
- Parameters
-
pView A pointer to the current view object. pNurbsSurface A pointer to the nurbs surface object. emit_message Indicates that a message should be sent to the emit_message_function
◆ InsertNurbsFromMessage()
|
static |
This method has been deprecated. This method inserts the surface into the scene based on the HNet message.
- Parameters
-
in_data A character pointer containing the surface data. data_length The size of the message. pView A pointer to the current view object.
Referenced by HNurbsMessageHandler::ProcessMessage().
◆ ModifyControlPointFromMessage()
|
static |
This method receives a modify control points based on an HNet message.
- Parameters
-
in_data A character pointer containing the new control point data. data_length The size of the message. pView A pointer to the current view object.
Referenced by HNurbsMessageHandler::ProcessMessage().
◆ OnLButtonDown()
|
virtual |
OnLButtonDown records the control point that will be used to manipulate the surface.
- Parameters
-
hevent An HEventInfo object containing information about the current event.
- Returns
- An HOperatorReturn indicating the status of the event.
Reimplemented from HBaseOperator.
◆ OnLButtonDownAndMove()
|
virtual |
OnLButtonDownAndMove receives control point manipulation information in plane parallel to viewplane and update 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.
◆ OnLButtonUp()
|
virtual |
OnLButtonUp finalizes nurbs manipulation.
- Parameters
-
hevent An HEventInfo object containing information about the current event.
- Returns
- An HOperatorReturn indicating the status of the event.
Reimplemented from HBaseOperator.
