        Determines how the mesh surface triangles are derived from the
        set of vertices (points) represented by the `x`, `y` and `z`
        arrays, if the `i`, `j`, `k` arrays are not supplied. For
        general use of `mesh3d` it is preferred that `i`, `j`, `k` are
        supplied. If "-1", Delaunay triangulation is used, which is
        mainly suitable if the mesh is a single, more or less layer
        surface that is perpendicular to `delaunayaxis`. In case the
        `delaunayaxis` intersects the mesh surface at more than one
        point it will result triangles that are very long in the
        dimension of `delaunayaxis`. If ">0", the alpha-shape algorithm
        is used. In this case, the positive `alphahull` value signals
        the use of the alpha-shape algorithm, _and_ its value acts as
        the parameter for the mesh fitting. If 0,  the convex-hull
        algorithm is used. It is suitable for convex bodies or if the
        intention is to enclose the `x`, `y` and `z` point set into a
        convex hull.

        The 'colorbar' property is an instance of ColorBar
        that may be specified as:
          - An instance of plotly.graph_objs.mesh3d.ColorBar
          - A dict of string/value properties that will be passed
            to the ColorBar constructor
    
            Supported dict properties:
                
                bgcolor
                    Sets the color of padded area.
                bordercolor
                    Sets the axis line color.
                borderwidth
                    Sets the width (in px) or the border enclosing
                    this color bar.
                dtick
                    Sets the step in-between ticks on this axis.
                    Use with `tick0`. Must be a positive number, or
                    special strings available to "log" and "date"
                    axes. If the axis `type` is "log", then ticks
                    are set every 10^(n*dtick) where n is the tick
                    number. For example, to set a tick mark at 1,
                    10, 100, 1000, ... set dtick to 1. To set tick
                    marks at 1, 100, 10000, ... set dtick to 2. To
                    set tick marks at 1, 5, 25, 125, 625, 3125, ...
                    set dtick to log_10(5), or 0.69897000433. "log"
                    has several special values; "L<f>", where `f`
                    is a positive number, gives ticks linearly
                    spaced in value (but not position). For example
                    `tick0` = 0.1, `dtick` = "L0.5" will put ticks
                    at 0.1, 0.6, 1.1, 1.6 etc. To show powers of 10
                    plus small digits between, use "D1" (all
                    digits) or "D2" (only 2 and 5). `tick0` is
                    ignored for "D1" and "D2". If the axis `type`
                    is "date", then you must convert the time to
                    milliseconds. For example, to set the interval
                    between ticks to one day, set `dtick` to
                    86400000.0. "date" also has special values
                    "M<n>" gives ticks spaced by a number of
                    months. `n` must be a positive integer. To set
                    ticks on the 15th of every third month, set
                    `tick0` to "2000-01-15" and `dtick` to "M3". To
                    set ticks every 4 years, set `dtick` to "M48"
                exponentformat
                    Determines a formatting rule for the tick
                    exponents. For example, consider the number
                    1,000,000,000. If "none", it appears as
                    1,000,000,000. If "e", 1e+9. If "E", 1E+9. If
                    "power", 1x10^9 (with 9 in a super script). If
                    "SI", 1G. If "B", 1B.
                len
                    Sets the length of the color bar This measure
                    excludes the padding of both ends. That is, the
                    color bar length is this length minus the
                    padding on both ends.
                lenmode
                    Determines whether this color bar's length
                    (i.e. the measure in the color variation
                    direction) is set in units of plot "fraction"
                    or in *pixels. Use `len` to set the value.
                nticks
                    Specifies the maximum number of ticks for the
                    particular axis. The actual number of ticks
                    will be chosen automatically to be less than or
                    equal to `nticks`. Has an effect only if
                    `tickmode` is set to "auto".
                outlinecolor
                    Sets the axis line color.
                outlinewidth
                    Sets the width (in px) of the axis line.
                separatethousands
                    If "true", even 4-digit integers are separated
                showexponent
                    If "all", all exponents are shown besides their
                    significands. If "first", only the exponent of
                    the first tick is shown. If "last", only the
                    exponent of the last tick is shown. If "none",
                    no exponents appear.
                showticklabels
                    Determines whether or not the tick labels are
                    drawn.
                showtickprefix
                    If "all", all tick labels are displayed with a
                    prefix. If "first", only the first tick is
                    displayed with a prefix. If "last", only the
                    last tick is displayed with a suffix. If
                    "none", tick prefixes are hidden.
                showticksuffix
                    Same as `showtickprefix` but for tick suffixes.
                thickness
                    Sets the thickness of the color bar This
                    measure excludes the size of the padding, ticks
                    and labels.
                thicknessmode
                    Determines whether this color bar's thickness
                    (i.e. the measure in the constant color
                    direction) is set in units of plot "fraction"
                    or in "pixels". Use `thickness` to set the
                    value.
                tick0
                    Sets the placement of the first tick on this
                    axis. Use with `dtick`. If the axis `type` is
                    "log", then you must take the log of your
                    starting tick (e.g. to set the starting tick to
                    100, set the `tick0` to 2) except when
                    `dtick`=*L<f>* (see `dtick` for more info). If
                    the axis `type` is "date", it should be a date
                    string, like date data. If the axis `type` is
                    "category", it should be a number, using the
                    scale where each category is assigned a serial
                    number from zero in the order it appears.
                tickangle
                    Sets the angle of the tick labels with respect
                    to the horizontal. For example, a `tickangle`
                    of -90 draws the tick labels vertically.
                tickcolor
                    Sets the tick color.
                tickfont
                    Sets the color bar's tick label font
                tickformat
                    Sets the tick label formatting rule using d3
                    formatting mini-languages which are very
                    similar to those in Python. For numbers, see: h

                ticklen
                    Sets the tick length (in px).
                tickmode
                    Sets the tick mode for this axis. If "auto",
                    the number of ticks is set via `nticks`. If
                    "linear", the placement of the ticks is
                    determined by a starting position `tick0` and a
                    tick step `dtick` ("linear" is the default
                    value if `tick0` and `dtick` are provided). If
                    "array", the placement of the ticks is set via
                    `tickvals` and the tick text is `ticktext`.
                    ("array" is the default value if `tickvals` is
                    provided).
                tickprefix
                    Sets a tick label prefix.
                ticks
                    Determines whether ticks are drawn or not. If
                    "", this axis' ticks are not drawn. If
                    "outside" ("inside"), this axis' are drawn
                    outside (inside) the axis lines.
                ticksuffix
                    Sets a tick label suffix.
                ticktext
                    Sets the text displayed at the ticks position
                    via `tickvals`. Only has an effect if
                    `tickmode` is set to "array". Used with

                ambient
                    Ambient light increases overall color
                    visibility but can wash out the image.
                diffuse
                    Represents the extent that incident rays are
                    reflected in a range of angles.
                facenormalsepsilon
                    Epsilon for face normals calculation avoids
                    math issues arising from degenerate geometry.
                fresnel
                    Represents the reflectance as a dependency of
                    the viewing angle; e.g. paper is reflective
                    when viewing it from the edge of the paper
                    (almost 90 degrees), causing shine.
                roughness
                    Alters specular reflection; the rougher the
                    surface, the wider and less contrasty the
                    shine.
                specular
                    Represents the level that incident rays are
                    reflected in a single direction, causing shine.
                vertexnormalsepsilon
                    Epsilon for vertex normals calculation avoids
                    math issues arising from degenerate geometry.

            positive `alphahull` value signals the use of the
            alpha-shape algorithm, _and_ its value acts as the
            parameter for the mesh fitting. If 0,  the convex-hull
            algorithm is used. It is suitable for convex bodies or

            Determines whether the colorscale is a default palette

            array are all positive, all negative or mixed.

            Determines whether or not the color domain is computed

        Construct a new Mesh3d object
        
        Draws sets of triangles with coordinates given by three
        1-dimensional arrays in `x`, `y`, `z` and (1) a sets of `i`,
        `j`, `k` indices (2) Delaunay triangulation or (3) the Alpha-
        shape algorithm or (4) the Convex-hull algorithm

        Parameters
        ----------
        arg
            dict of properties compatible with this constructor or
            an instance of plotly.graph_objs.Mesh3d
        alphahull
            Determines how the mesh surface triangles are derived
            from the set of vertices (points) represented by the
            `x`, `y` and `z` arrays, if the `i`, `j`, `k` arrays
            are not supplied. For general use of `mesh3d` it is
            preferred that `i`, `j`, `k` are supplied. If "-1",
            Delaunay triangulation is used, which is mainly
            suitable if the mesh is a single, more or less layer
            surface that is perpendicular to `delaunayaxis`. In
            case the `delaunayaxis` intersects the mesh surface at
            more than one point it will result triangles that are
            very long in the dimension of `delaunayaxis`. If ">0",
            the alpha-shape algorithm is used. In this case, the
            positive `alphahull` value signals the use of the
            alpha-shape algorithm, _and_ its value acts as the
            parameter for the mesh fitting. If 0,  the convex-hull
            algorithm is used. It is suitable for convex bodies or
            if the intention is to enclose the `x`, `y` and `z`
            point set into a convex hull.
        autocolorscale
            Determines whether the colorscale is a default palette
            (`autocolorscale: true`) or the palette determined by
            `colorscale`. In case `colorscale` is unspecified or
            `autocolorscale` is true, the default  palette will be
            chosen according to whether numbers in the `color`
            array are all positive, all negative or mixed.
        cauto
            Determines whether or not the color domain is computed
            with respect to the input data (here `intensity`) or
            the bounds set in `cmin` and `cmax`  Defaults to
            `false` when `cmin` and `cmax` are set by the user.
        cmax
            Sets the upper bound of the color domain. Value should

            plotly.graph_objs.mesh3d.Lightposition instance or dict
            with compatible properties
        name
            Sets the trace name. The trace name appear as the
            legend item and on hover.
        opacity
            Sets the opacity of the surface.
        reversescale
            Reverses the color mapping if true. If true, `cmin`
            will correspond to the last color in the array and
            `cmax` will correspond to the first color.
        scene
            Sets a reference between this trace's 3D coordinate
            system and a 3D scene. If "scene" (the default value),
            the (x,y,z) coordinates refer to `layout.scene`. If
            "scene2", the (x,y,z) coordinates refer to
            `layout.scene2`, and so on.
        selectedpoints
            Array containing integer indices of selected points.
            Has an effect only for traces that support selections.
            Note that an empty array means an empty selection where
            the `unselected` are turned on for all points, whereas,
            any other non-array values means no selection all where
            the `selected` and `unselected` styles have no effect.
        showlegend
            Determines whether or not an item corresponding to this
            trace is shown in the legend.
        showscale
            Determines whether or not a colorbar is displayed for
            this trace.
        stream
            plotly.graph_objs.mesh3d.Stream instance or dict with
            compatible properties
        text
            Sets the text elements associated with the vertices. If
            trace `hoverinfo` contains a "text" flag and
            "hovertext" is not set, these elements will be seen in
            the hover labels.
        textsrc
            Sets the source reference on plot.ly for  text .
        uid

        vertexcolor
            Sets the color of each vertex Overrides "color".
        vertexcolorsrc
            Sets the source reference on plot.ly for  vertexcolor .
        visible
            Determines whether or not this trace is visible. If
            "legendonly", the trace is not drawn, but can appear as
            a legend item (provided that the legend itself is
            visible).
        x
            Sets the X coordinates of the vertices. The nth element
            of vectors `x`, `y` and `z` jointly represent the X, Y
            and Z coordinates of the nth vertex.
        xcalendar
            Sets the calendar system to use with `x` date data.
        xsrc
            Sets the source reference on plot.ly for  x .
        y
            Sets the Y coordinates of the vertices. The nth element
            of vectors `x`, `y` and `z` jointly represent the X, Y
            and Z coordinates of the nth vertex.
        ycalendar
            Sets the calendar system to use with `y` date data.
        ysrc
            Sets the source reference on plot.ly for  y .
        z
            Sets the Z coordinates of the vertices. The nth element
            of vectors `x`, `y` and `z` jointly represent the X, Y
            and Z coordinates of the nth vertex.
        zcalendar
            Sets the calendar system to use with `z` date data.
        zsrc
            Sets the source reference on plot.ly for  z .
