Member Function Documentation

◆ captureBuffersForFastPreSelection()

bool cvSelectionPipeline::captureBuffersForFastPreSelection ( )

Capture buffers for fast pre-selection.

Call this at the start of interactive selection mode to pre-cache the hardware selection buffers. Subsequent fastPreSelectAt() calls will be very fast until invalidateCachedSelection() is called.

◆ combineSelections()

cvSelectionData cvSelectionPipeline::combineSelections	(	const cvSelectionData &	sel1,
		const cvSelectionData &	sel2,
		CombineOperation	operation
	)

static

Combine two selections.

Parameters

◆ convertToCvSelectionData()

cvSelectionData cvSelectionPipeline::convertToCvSelectionData	(	vtkSelection *	selection,

static

Convert vtkSelection to cvSelectionData with actor info (ParaView-style)

Parameters

selection	The vtkSelection result from vtkHardwareSelector
fieldAssociation	Field association (cells or points)

◆ fastPreSelectAt()

vtkIdType cvSelectionPipeline::fastPreSelectAt	(	int	x,
		int	y,
		bool	selectCells
	)

Perform fast pre-selection at a screen position.

Parameters

x	Screen X coordinate
y	Screen Y coordinate
selectCells	True for cell selection, false for points

Returns: Selected element ID, or -1 if nothing found

This method uses cached hardware selection buffers when available, falling back to a single-pixel selection if no cache exists. Much faster than software picking for interactive hover.

NOTE: This only returns the ID. For tooltip display with multiple actors, use getPixelSelectionInfo() instead to get the correct polyData.
