@item Plugin(Smooth)
Plugin(Smooth) averages the values at the nodes of the view `View'.

If `View' < 0, the plugin is run on the current view.

Plugin(Smooth) is executed in-place.

@item View
Default value: @code{-1}
@end table

@item Plugin(SphericalRaise)
Plugin(SphericalRaise) transforms the coordinates of the elements in the view `View' using the values associated with the `TimeStep'-th time step.

Instead of elevating the nodes along the X, Y and Z axes as with the View[`View'].RaiseX, View[`View'].RaiseY and View[`View'].RaiseZ options, the raise is applied along the radius of a sphere centered at (`Xc', `Yc', `Zc').

To produce a standard radiation pattern, set `Offset' to minus the radius of the sphere the original data lives on.

If `View' < 0, the plugin is run on the current view.

Plugin(SphericalRaise) is executed in-place.
Numeric options:

@end table

@item Plugin(StreamLines)
Plugin(StreamLines) computes stream lines from the `TimeStep'-th time step of a vector view `View' and optionally interpolates the scalar view `OtherView' 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 along U and V that are to be transported is set with the options `NumPointsU' and `NumPointsV'. 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 `TimeStep' < 0, the plugin tries to compute streamlines of the unsteady flow.

If `View' < 0, the plugin is run on the current view.

Plugin(StreamLines) creates one new view. This view contains multi-step vector points if `OtherView' < 0, or single-step scalar lines if `OtherView' >= 0.

@item Plugin(Tetrahedralize)
Plugin(Tetrahedralize) tetrahedralizes the points in the view `View'.

If `View' < 0, the plugin is run on the current view.

Plugin(Tetrahedralize) creates one new view.
Numeric options:
@table @code
@item View
Default value: @code{-1}
@end table

@item Plugin(Transform)
Plugin(Transform) transforms the homogeneous node coordinates (x,y,z,1) of the elements in the view `View' by the matrix

[`A11' `A12' `A13' `Tx']
[`A21' `A22' `A23' `Ty']
[`A31' `A32' `A33' `Tz'].

If `SwapOrientation' is set, the orientation of the elements is reversed.

If `View' < 0, the plugin is run on the current view.

Plugin(Transform) is executed in-place.
Numeric options:
@table @code

@end table

@item Plugin(Triangulate)
Plugin(Triangulate) triangulates the points in the view `View', assuming that all the points belong to a surface that can be projected one-to-one onto a plane.

If `View' < 0, the plugin is run on the current view.

Plugin(Triangulate) creates one new view.
Numeric options:
@table @code
@item View
Default value: @code{-1}
@end table

@item Plugin(Warp)
Plugin(Warp) transforms the elements in the view `View' by adding to their node coordinates the vector field stored in the `TimeStep'-th time step of the view `OtherView', scaled by `Factor'.

If `View' < 0, the plugin is run on the current view.

If `OtherView' < 0, the vector field is taken as the field of surface normals multiplied by the `TimeStep' value in `View'. (The smoothing of the surface normals is controlled by the `SmoothingAngle' parameter.)

Plugin(Warp) is executed in-place.
Numeric options:
