This variant of plsurf3d (see that function's documentation for
more details) should be suitable for the case where the area of
the ,
x coordinate grid where
y is defined can be
non-rectangular. The limits of that grid are provided by
the parameters z,
indexxmin,
indexxmax,
and indexymin.
indexymax
x
(const PLFLT *, input)
Pointer to set of x coordinate values at which the function is evaluated.
y
(const PLFLT *, input)
Pointer to set of y coordinate values at which the function is evaluated.
z
(const PLFLT * const *, input)
Pointer to a vectored two-dimensional array with set of function values.
nx
(PLINT, input)
Number of values at
which function is evaluated.
x
ny
(PLINT, input)
Number of values at
which function is evaluated.
y
opt
(PLINT, input)
Determines the way in which the surface is represented. To specify more than one option just add the options, e.g. FACETED + SURF_CONT
: Network
of lines is drawn connecting points at which function is
defined.
opt=FACETED
: A contour
plot is drawn at the base XY plane using parameters
opt=BASE_CONTnlevel and clevel.
: A contour
plot is drawn at the surface plane using parameters
opt=SURF_CONTnlevel and clevel.
: draws a curtain
between the base XY plane and the borders of the plotted function.
opt=DRAW_SIDES
:
the surface is colored according to the value of Z; if
opt=MAG_COLORMAG_COLOR is not used, then the default
the surface is colored according to the intensity of the
reflected light in the surface from a light source whose
position is set using pllightsource.
clevel
(const PLFLT *, input)
Pointer to the array that defines the contour level spacing.
nlevel
(PLINT, input)
Number of elements in the clevel array.
indexxmin
(PLINT, input)
The index value (which must be ≥ 0) that corresponds to
the first index where
x is defined.
z
indexxmax
(PLINT, input)
The index value (which must be ≤
) which corresponds (by
convention) to one more than the last
nx index value where
x is defined.
z
indexymin
(const PLINT *, input)
Array of index
values which all must be ≥ 0. These values are the first
y index where
y is defined for a
particular z index in the
range from x to
indexxmin. The dimension of
indexxmax - 1 is
indexymin.
indexxmax
indexymax
(const PLINT *, input)
Array of index
values which all must be ≤
y. These values
correspond (by convention) to one more than the last
ny index where
y is defined for a
particular z index in the
range from x to
indexxmin. The dimension of
indexxmax - 1 is
indexymax.
indexxmax
Redacted form: plsurf3dl(x, y, z, opt, clevel,
indexxmin, indexymin, indexymax)
This function is not used in any examples.
