Member Function Documentation

◆ _drawCubeFaces()

void VAPoR::Manip::_drawCubeFaces	(	double *	extents,
		bool	isSelected
	)

protected

General utility function for drawing axis-aligned cubes.

Parameters

[in]	extents	: extents of box to be drawn
[in]	isSelected	indicates if this box is to be drawn with the selection color or not

◆ _mouseDrag()

virtual void VAPoR::Manip::_mouseDrag	(	double	screenCoords[2],
		double	handleMidpoint[3]
	)

protectedpure virtual

Handles logic for moving a handle while a mouse button is held down. param[in] screenCoords is the current position of the mouse cursor param[in] handleMidpoint is the center of the handle being moved

◆ _mouseIsOverHandle()

virtual int VAPoR::Manip::_mouseIsOverHandle	(	const double	screenCoords[2],
		double	handleMid[3]
	)		const

protectedpure virtual

Pure virtual method: Determine which handle (if any) is under mouse

Parameters

[in]	mouse	coordinates in screen
[out]	handleMid	is the coordinates of the center of the selected handle (if selected).

Returns: handle index, or -1 if no intersection

◆ _mousePress()

virtual void VAPoR::Manip::_mousePress	(	double	screenCoords[2],
		double	handleMidpoint[3],
		int	buttonNum
	)

protectedpure virtual

Handles logic for a mouse-press event on one of the manip handles

Parameters

[in]	screenCoords	is a pixel location on the visualizer window
[in]	handleMidpoint	is the center of a handle to test that gets tested against the screenCoords array.

param[in] buttonNum is the button of the mouse that is clicked, which determines whether we are moving or stretching the manipulator.

◆ _mouseRelease()

virtual void VAPoR::Manip::_mouseRelease ( double screenCoords[2] )

protectedpure virtual

param[in] screenCoords - coordinates of the cursor upon mose release

Handles logic to set the current extents of the manipulator, held in the _selection array

◆ _stretchCorners()

virtual void VAPoR::Manip::_stretchCorners ( double corners[8][3] ) const

protectedpure virtual

Adjust the corners of the manipulator extents according to _dragDistance param[in] corners describes the bounding box of the manipulator

◆ GetBox()

virtual void VAPoR::Manip::GetBox	(	std::vector< double > &	llc,
		std::vector< double > &	urc
	)		const

pure virtual

Method to retrieve the manipulator's current extents

Parameters

[out]	llc	- The lower-left coordinates of the manipulator
[out]	urc	- The upper-right coordinates of the manipulator

Implemented in VAPoR::TranslateStretchManip.

◆ MouseEvent()

virtual bool VAPoR::Manip::MouseEvent	(	int	buttonNum,
		std::vector< double >	screenCoords,
		double	handleMidpoint[3],
		bool	release = `false`
	)

pure virtual

Notify that manipulator that is being moved with the mouse

Parameters

[in]	buttonNum	- The mouse button being used to move the manipulator
[in]	screenCoords	- The current coordinates of the mouse cursor

Implemented in VAPoR::TranslateStretchManip.

◆ Render()

virtual void VAPoR::Manip::Render ( )

pure virtual

Pure virtual function renders the geometry of the Manip.

Implemented in VAPoR::TranslateStretchManip.

◆ Update()

virtual void VAPoR::Manip::Update	(	std::vector< double >	llc,
		std::vector< double >	urc,
		std::vector< double >	minExtents,
		std::vector< double >	maxExtents,
		VAPoR::Transform *	rpTransform,
		VAPoR::Transform *	dmTransform,
		bool	constrain
	)

pure virtual

Update the box manipulator's extents

Parameters

[in]	llc	: The lower-left corner to update the manipulator with
[in]	urc	: The upper-right corner to update the manipulator with
[in]	minExtents	: The minimum extents that the manipulator can draw to
[in]	maxExtents	: The maximum extents that the manipulator can draw to
[in]	rpTransform	The current scene transform used by the current RenderParams
[in]	dmTransform	The current scene transform used by the current DataMgr
[in]	constrain	Indicates whether the manipulator box is bound by domain extents

Implemented in VAPoR::TranslateStretchManip.
