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:

  1. Left Button Down: The operation is initiated and control point for dragging is specified.
  2. Left Button Down and Drag: The control point moves with mouse position and the surface is recalculated.
  3. Left Button Up: The surface editing is finalized.

More Detailed Description: see event methods.

Constructor & Destructor Documentation

◆ HOpCreateNurbs3D()

HOpCreateNurbs3D::HOpCreateNurbs3D ( HBaseView view,
int  DoRepeat = 0,
int  DoCapture = 1 
)

Constructs an HOpCreateNurbs3D object.

Parameters
viewA pointer to an HBaseView object.
DoRepeatAn integer denoting whether this is a repeatable operator. This parameter has been deprecated.
DoCaptureAn 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 HBaseOperator* HOpCreateNurbs3D::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 void HOpCreateNurbs3D::EmitFinishNurbsEditing ( HBaseView pView,
HC_KEY  key,
bool  emit_message 
)
static

This method emits the finalized Nurbs editing message to other clients.

Parameters
pViewA pointer to the current view object.
keyThe surface key.
emit_messageIndicates that a message should be sent to the emit_message_function

◆ EmitModifyControlPointMessage()

static void HOpCreateNurbs3D::EmitModifyControlPointMessage ( HBaseView pView,
HC_KEY  key,
int  control_point,
float  x,
float  y,
float  z 
)
static

This method sends a modify control point message to other clients.

Parameters
pViewA pointer to the current view object.
keyThe surface key.
control_pointThe number identifying the manipulated control point of surface.
xThe new control point x position.
yThe new control point y position.
zThe new control point z position.

◆ FinishNurbsEditingFromMessage()

static void HOpCreateNurbs3D::FinishNurbsEditingFromMessage ( const char *  in_data,
unsigned int  data_length,
HBaseView pView 
)
static

This method receives the Finish Nurbs editing message.

Parameters
in_dataA character pointer indicating the end of surface editing.
data_lengthThe size of the message.
pViewA pointer to the current view object.

Referenced by HNurbsMessageHandler::ProcessMessage().

◆ GetName()

virtual const char* HOpCreateNurbs3D::GetName ( )
virtual
Returns
A pointer to a character string denoting the name of the operator which is 'HOpCreateNurbs3D'.

Reimplemented from HBaseOperator.

◆ InsertNurbs()

static HC_KEY HOpCreateNurbs3D::InsertNurbs ( HBaseView pView,
HNurbsSurface pNurbsSurface,
bool  emit_message 
)
static

This method insert the given surface into the scene.

Parameters
pViewA pointer to the current view object.
pNurbsSurfaceA pointer to the nurbs surface object.
emit_messageIndicates that a message should be sent to the emit_message_function

◆ InsertNurbsFromMessage()

static void HOpCreateNurbs3D::InsertNurbsFromMessage ( const char *  in_data,
unsigned int  data_length,
HBaseView m_pView 
)
static

This method has been deprecated. This method inserts the surface into the scene based on the HNet message.

Parameters
in_dataA character pointer containing the surface data.
data_lengthThe size of the message.
pViewA pointer to the current view object.

Referenced by HNurbsMessageHandler::ProcessMessage().

◆ ModifyControlPointFromMessage()

static void HOpCreateNurbs3D::ModifyControlPointFromMessage ( const char *  in_data,
unsigned int  data_length,
HBaseView pView 
)
static

This method receives a modify control points based on an HNet message.

Parameters
in_dataA character pointer containing the new control point data.
data_lengthThe size of the message.
pViewA pointer to the current view object.

Referenced by HNurbsMessageHandler::ProcessMessage().

◆ OnLButtonDown()

virtual int HOpCreateNurbs3D::OnLButtonDown ( HEventInfo hevent)
virtual

OnLButtonDown records the control point that will be used to manipulate the surface.

Parameters
heventAn HEventInfo object containing information about the current event.

◆ OnLButtonUp()

virtual int HOpCreateNurbs3D::OnLButtonUp ( HEventInfo hevent)
virtual

OnLButtonUp finalizes nurbs manipulation.

Parameters
heventAn HEventInfo object containing information about the current event.
Returns
An HOperatorReturn indicating the status of the event.
