Member Function Documentation

void CIvfOldScene::beginTransform (   )  [protected, virtual]

Start transform Implements a OpenGL transform. This routine should call a glPushMatrix() and then call OpenGL routines transforming the object. The method is the first routine to be called in the render() method. Reimplemented from CIvfSelectComposite.

void CIvfOldScene::createGeometry (   )  [protected, virtual]

Forces an object recalculation. Reimplemented from CIvfSelectComposite.

void CIvfOldScene::endTransform (   )  [protected, virtual]

End transform This is the last method called in the render() method. if a glPushMatrix() is called in the beginTransform() a glPopMatrix() should be called in this routine. Reimplemented from CIvfSelectComposite.

CIvfCamera* CIvfOldScene::getCamera (   )

Returns the current camera object Reimplemented from CIvfSelectComposite.

bool CIvfOldScene::getShowCursor (   )

Return cursor state

bool CIvfOldScene::getShowGrid (   )

Return grid state

bool CIvfOldScene::getSnapToGrid (   )

Return grid snap state

int CIvfOldScene::getTempRenderStyle (   )

Return temporary render style

CIvfShape* CIvfOldScene::getTempShape (   )

Return temporary shape

CIvfCoordinateSystem* CIvfOldScene::getWorldSystem (   )

Return coordinate system object

int CIvfOldScene::isCursorLocked (   )

Returns true if cursor is locked otherwise false

void CIvfOldScene::lockCursor (   )

Locks 3D cursor in XY-direction When this method is called the 3D cursor can only be moved in the Z-direction of the current coordinate system.

void CIvfOldScene::setCursor (  CIvfCursor *  cursor  )

Set cursor object The cursor is a 3D representation of a mouse cursor. If the cursor is not referenced it will be deleted.

void CIvfOldScene::setNodeSize (  double  size  )

Not supported

void CIvfOldScene::setObjectSize (  double  size  )

Not supported

void CIvfOldScene::setShowCursor (  bool  flag  )

Enable/disable cursor

void CIvfOldScene::setShowGrid (  bool  flag  )

Enable/disable grid

void CIvfOldScene::setSnapToGrid (  bool  flag  )

Enable/disable grid snap

void CIvfOldScene::setTempRenderStyle (  int  style  )

Set temporary drawing style The temporary object can be drawn in to ways: Parameters: IVF_TEMP_SOLID  solid shape IVF_TEMP_WIRE  wire frame representation

void CIvfOldScene::setTempShape (  CIvfShape *  shape  )

Set temporary shape The temporary shape is not included in the scene graph and can be used to draw outlines of objects that is to be placed in the scene.

void CIvfOldScene::setTransparentShape (  CIvfShape *  shape  )

Set transparent shape The transparent shape is rendered last in the rendering stage of the scene and is not contained in the scene graph.

void CIvfOldScene::setWorkspace (  double  size  )

Set the workspace size Sets the size of the workspace and scales corresponding interaction objects.

void CIvfOldScene::setWorldSystem (  CIvfCoordinateSystem *  world  )

Set current coordinate system object The coordinate system object is used to calculate the position of the 3D cursor. If the coordiate system object is not referenced by any other objects it will be deleted by IvfScene.

void CIvfOldScene::unlockCursor (   )

Unlocks the 3D cursor

void CIvfOldScene::updateCursor (  int  x, int  y )

Update 3D cursor Projects a ray from the viewing plane to the current coordinate system XY-plane and moves the 3D cursor to this position. Parameters: x  mouse x position y  mouse y position
