ATTRIBUTES

• 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

  Has an effect only if `color` is set to a numerical array. 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

  Has an effect only if `color` is set to a numerical array and `cmin`, `cmax` are set by the user. In this case, it controls whether the range of colors in `colorscale` is mapped to the range of values in the `color` array (`cauto: true`), or the `cmin`/`cmax` values (`cauto: false`). Defaults to `false` when `cmin`, `cmax` are set by the user.

• cmax

  Has an effect only if `color` is set to a numerical array. Sets the upper bound of the color domain. Value should be associated to the `color` array index, and if set, `cmin` must be set as well.

• cmin

  Has an effect only if `color` is set to a numerical array. Sets the lower bound of the color domain. Value should be associated to the `color` array index, and if set, `cmax` must be set as well.

• color

  Sets the color of the whole mesh

• colorbar

• colorscale

  Sets the colorscale and only has an effect if `color` is set to a numerical array. The colorscale must be an array containing arrays mapping a normalized value to an rgb, rgba, hex, hsl, hsv, or named color string. At minimum, a mapping for the lowest (0) and highest (1) values are required. For example, `[[0, 'rgb(0,0,255)', [1, 'rgb(255,0,0)']]`. To control the bounds of the colorscale in color space, use `cmin` and `cmax`. Alternatively, `colorscale` may be a palette name string of the following list: Greys, YlGnBu, Greens, YlOrRd, Bluered, RdBu, Reds, Blues, Picnic, Rainbow, Portland, Jet, Hot, Blackbody, Earth, Electric, Viridis, Cividis

• contour

• customdata

  Assigns extra data each datum. This may be useful when listening to hover, click and selection events. Note that, *scatter* traces also appends customdata items in the markers DOM elements

• customdatasrc

  Sets the source reference on plot.ly for customdata .

• delaunayaxis

  Sets the Delaunay axis, which is the axis that is perpendicular to the surface of the Delaunay triangulation. It has an effect if `i`, `j`, `k` are not provided and `alphahull` is set to indicate Delaunay triangulation.

• facecolor

  Sets the color of each face Overrides *color* and *vertexcolor*.

• facecolorsrc

  Sets the source reference on plot.ly for facecolor .

• flatshading

  Determines whether or not normal smoothing is applied to the meshes, creating meshes with an angular, low-poly look via flat reflections.

• hoverinfo

  Determines which trace information appear on hover. If `none` or `skip` are set, no information is displayed upon hovering. But, if `none` is set, click and hover events are still fired.

• hoverinfosrc

  Sets the source reference on plot.ly for hoverinfo .

• hoverlabel

• i

  A vector of vertex indices, i.e. integer values between 0 and the length of the vertex vectors, representing the *first* vertex of a triangle. For example, `{i[m], j[m], k[m]}` together represent face m (triangle m) in the mesh, where `i[m] = n` points to the triplet `{x[n], y[n], z[n]}` in the vertex arrays. Therefore, each element in `i` represents a point in space, which is the first vertex of a triangle.

• ids

  Assigns id labels to each datum. These ids for object constancy of data points during animation. Should be an array of strings, not numbers or any other type.

• idssrc

  Sets the source reference on plot.ly for ids .

• intensity

  Sets the vertex intensity values, used for plotting fields on meshes

• intensitysrc

  Sets the source reference on plot.ly for intensity .

• isrc

  Sets the source reference on plot.ly for i .

• j

  A vector of vertex indices, i.e. integer values between 0 and the length of the vertex vectors, representing the *second* vertex of a triangle. For example, `{i[m], j[m], k[m]}` together represent face m (triangle m) in the mesh, where `j[m] = n` points to the triplet `{x[n], y[n], z[n]}` in the vertex arrays. Therefore, each element in `j` represents a point in space, which is the second vertex of a triangle.

• jsrc

  Sets the source reference on plot.ly for j .

• k

  A vector of vertex indices, i.e. integer values between 0 and the length of the vertex vectors, representing the *third* vertex of a triangle. For example, `{i[m], j[m], k[m]}` together represent face m (triangle m) in the mesh, where `k[m] = n` points to the triplet `{x[n], y[n], z[n]}` in the vertex arrays. Therefore, each element in `k` represents a point in space, which is the third vertex of a triangle.

• ksrc

  Sets the source reference on plot.ly for k .

• legendgroup

  Sets the legend group for this trace. Traces part of the same legend group hide/show at the same time when toggling legend items.

• lighting

• lightposition

• name

  Sets the trace name. The trace name appear as the legend item and on hover.

• opacity

  Sets the opacity of the surface.

• reversescale

  Has an effect only if `color` is set to a numerical array. Reverses the color mapping 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

• 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 .

• transforms

• 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.
