Member Function Documentation

V2f Vis::CameraViewport::GetDataHit	(	int	viwportWidth,
		int	viewPortHeight,
		int	posX,
		int	posY
	)

mappping from screen space to "data" space provided screen coordinates the function returns normalized coordinates, where the focused data is hit

Parameters:

	viwportWidth	current viewport width
	viwportHEight	current viewport height
	posX	the hitPoint xPos
	posY	the hitPoint yPos
