@item Plugin(Annotate)
Plugin(Annotate) adds the text string `Text',
in font `Font' and size `FontSize', in the view
`iView'. If `ThreeD' is equal to 1, the plugin inserts
the string in model coordinates at the position
(`X',`Y',`Z'). If `ThreeD' is equal to 0, the plugin
inserts the string in screen coordinates at
the position (`X',`Y'). The string is aligned
according to `Align'. If `iView' < 0, the plugin
is run on the current view.

Plugin(Annotate) is executed in-place for list-based
datasets or creates a new view for other datasets.

U) and (`X2',`Y2',`Z2') (axis of V). The number of
points along U and V is set with the options
`nPointsU' and `nPointsV'. If `ConnectPoints' is
zero, the plugin creates points; otherwise, the
plugin generates quadrangles, lines or points
 depending on the values of `nPointsU' and
`nPointsV'. If `iView' < 0, the plugin is run on
the current view.

@item Plugin(CutMap)

`A' from the view `iView' and draws the
`dTimeStep'-th value of the view `dView' on the
isosurface. If `iView' < 0, the plugin is run
on the current view. If `dTimeStep' < 0, the
plugin uses, for each time step in `iView', the
corresponding time step in `dView'. If `dView'
< 0, the plugin uses `iView' as the value source.
If `ExtractVolume' is nonzero, the plugin
extracts the isovolume with values greater (if
`ExtractVolume' > 0) or smaller (if `ExtractVolume'

@item Plugin(Evaluate)
Plugin(Evaluate) sets the `Component'-th
component of the `TimeStep'-th time step in the
view `iView' to the expression `Expression'.
`Expression' can contain:

- the usual mathematical functions (Log, Sqrt,
Sin, Cos, Fabs, ...) and operators (+, -, *, /, ^);

- the symbols x, y and z, to retrieve the
coordinates of the current node;

- the symbols Time and TimeStep, to retrieve the
current time and time step values;

- the symbol v, to retrieve the `Component'-th
component of the field in `iView' at the
`TimeStep'-th time step;

- the symbols v0, v1, v2, ..., v8, to retrieve each
component of the field in `iView' at the
`TimeStep'-th time step;

- the symbol w, to retrieve the `Component'-th
component of the field in `ExternalView' at the
`ExternalTimeStep'-th time step. If `ExternalView'
and `iView' are based on different spatial grids,
or if their data types are different, `ExternalView'
is interpolated onto `iView';

- the symbols w0, w1, w2, ..., w8, to retrieve each
component of the field in `ExternalView' at the
`ExternalTimeStep'-th time step.

If `TimeStep' < 0, the plugin automatically loops
over all the time steps in `iView' and evaluates
`Expression' for each one. If `ExternalTimeStep'
< 0, the plugin uses `TimeStep' instead. If
`Component' < 0, the plugin automatically loops
over all the components in the view and
evaluates `Expression' for each one. If `iView'
< 0, the plugin is run on the current view. If
`ExternalView' < 0, the plugin uses `iView'
instead.

@item Plugin(Extract)
Plugin(Extract) extracts a combination of
components from the `TimeStep'th time step
in the view `iView'. If only `Expression0' is
given (and `Expression1', ..., `Expression8' are
all empty), the plugin creates a scalar view.
If `Expression0', `Expression1' and/or
`Expression2' are given (and `Expression3',
..., `Expression8' are all empty) the plugin
creates a vector view. Otherwise the plugin
creates a tensor view. In addition to the usual
mathematical functions (Exp, Log, Sqrt, Sin, Cos,
Fabs, etc.) and operators (+, -, *, /, ^), all
expressions can contain the symbols v0, v1, v2,
 ..., vn, which represent the n components of the
field, and the symbols x, y and z, which represent
the three spatial coordinates. If `TimeStep' < 0,
the plugin extracts data from all the time steps
in the view. If `iView' < 0, the plugin is run on
the current view.

@item Plugin(GSHHS)
Plugin(GSHHS) read different kind of contour lines data
and write a .geo file on the surface of a sphere (the Earth).
The principal application is to load GSHHS data
 (see
http://www.soest.hawaii.edu/wessel/gshhs/gshhs.html).
Valid values for "Format" are ):
 -"gshhs" : open GSHHS file
 -"loops2" : import 2D contour lines in simple text format :
   NB_POINTS_IN_FIRST_LOOP FIRST_LOOP_IS_CLOSED
   COORD1 COORD2
   COORD1 COORD2
   ...    ...
   NB_POINTS_IN_SECOND_LOOP SECOND_LOOP_IS_CLOSED
   ...
   (LOOP_IS_CLOSED specify if this coast line describe a closed curve
   (0=no, 1=yes).
In the case of "loops2" format, you can specify the the coordinate
system used in the input file with the "Coordinate" option, valid
values are
 -"lonlat" for longitude-latidute radian,
 -"lonlat_degrees" for longitude-latitude degrees,
 -"UTM" for universal transverse mercartor ("UTMZone" option should
  be specified)
 -"cartesian" for full 3D coordinates
 -"radius" specify the earth radius.
If the "iField" option is set, consecutive points closer than the
value of the field iField (in meters) will not be added.
If "MinStraitsFactor" >0 and if a field iField is provided, coastlines
closer than MinStraitsFactor*field(IField) are merged and inner corners
 which form an angle < pi/3 are removed.
The output is always in stereographic coordinates, if the "WritePolarSphere"
option is not 0, a sphere is added to the geo file.
WARNING : this plugin is still experimental and need polishing and
error-handling. In particular, it will probably crash if an inexistant
field id is given or if the input/output cannot be open.

@item Plugin(StreamLines)
Plugin(StreamLines) computes stream lines
from the `TimeStep'-th time step of a vector
view `iView' and optionally interpolates the
scalar view `dView' on the resulting stream
lines. The plugin takes as input a grid defined
by the 3 points (`X0',`Y0',`Z0') (origin),
(`X1',`Y1',`Z1') (axis of U) and (`X2',`Y2',`Z2')
(axis of V). The number of points that are to
be transported along U and V is set with the
options `nPointsU' and `nPointsV'. The equation
DX(t)/dt=V(x,y,z) is then solved with the initial
condition X(t=0) chosen as the grid and with V(x,y,z)
interpolated on the vector view. The time stepping
scheme is a RK44 with step size `DT' and `MaxIter'
maximum number of iterations. If `iView' < 0, the
plugin is run on the current view. If `TimeStep' < 0,
the plugin tries to compute streamlines of the unsteady
flow.

view contains multi-step vector points if `dView'

onto a plane. If `iView' < 0, the plugin is run on
the current view.

Plugin(Triangulate) creates one new view.

Numeric options:
@table @code
@item iView
Default value: @code{-1}
@end table

@item Plugin(Warp)
Plugin(Warp) transforms the elements in the
view `iView' by adding to their node coordinates
the vector field stored in the `TimeStep'-th time
step of the view `dView', scaled by `Factor'. If
`dView' < 0, the vector field is taken as the field
of surface normals multiplied by the `TimeStep'
value in `iView'. (The smoothing of the surface
normals is controlled by the `SmoothingAngle'
parameter.) If `iView' < 0, the plugin is run on
the current view.

Plugin(Warp) is executed in-place.

Numeric options:
@table @code
@item Factor
Default value: @code{1}
@item TimeStep
Default value: @code{0}
@item SmoothingAngle
Default value: @code{180}
@item dView
Default value: @code{-1}
@item iView
Default value: @code{-1}
