Detailed Description

This class defines a field of view.

This class defines a field of view for a given camera. Field of views are returned as point clouds defining the boundary of the field of view. The number of vertices is instrment dependent. The default Camera::PixelIfovOffsets assumes a square pixel and simply returns the offsets of the four corner vertices in microns from the current pixel center. If the instruments pixels are not square, the Camera::PixelIfov will need to be implemented in the the instrument's camera model. For an example, see VimsCamera::PixelIfov().

Member Function Documentation

QList< QList< QPointF > > Isis::PixelFOV::latLonVertices	(	Camera &	camera,
		const double	sample,
		const double	line,
		const int	numIfovs = 1
	)		const

Produces an fov for the given line sample.

This produces instantaneous fovs at several times during a pixel's exposure. Then, it combines those instantaneous fovs into a full fov for the entire duration of the pixel. By default produces an instantaneous fov. A full fov can be produced by using numIfovs > 1.

Parameters

camera	A pointer to the cube's camera.
sample	The sample of the pixel.
line	The line of the pixel.
numIfovs	The number of instantaneous fovs that will be combined. Defaults to 1, ie. an instantaneous fov.

Returns

QList<QList<QPointF>> A list of points defining the boundary of the full fov. If the pixel crosses the 360/0 boundary, this will contain 2 lists of points, one on each side of the boundary.

Exceptions

IException::Programmer

"The number of instantaneous field of views must be a positive integer."
