Create 3-D perspective image or surface mesh from a grid.
Reads a 2-D grid file and produces a 3-D perspective plot by drawing a mesh, painting a colored/gray-shaded surface made up of polygons, or by scanline conversion of these polygons to a raster image. Options include draping a data set on top of a surface, plotting of contours on top of the surface, and apply artificial illumination based on intensities provided in a separate grid file.

cmap (str) – The name of the color palette table to use.
drapegrid (str or xarray.DataArray) – The file name or a DataArray of the image grid to be draped on top of the relief provided by grid. [Default determines colors from grid]. Note that -Jz and -N always refers to the grid. The drapegrid only provides the information pertaining to colors, which (if drapegrid is a grid) will be looked-up via the CPT (see -C).
plane (float or str) –
level[+gfill]. Draws a plane at this z-level. If the optional color is provided via the +g modifier, and the projection is not oblique, the frontal facade between the plane and the data perimeter is colored.
surftype (str) – Specifies cover type of the grid. Select one of following settings: 1. ‘m’ for mesh plot [Default]. 2. ‘mx’ or ‘my’ for waterfall plots (row or column profiles). 3. ‘s’ for surface plot. 4. ‘i’ for image plot. 5. ‘c’. Same as ‘i’ but will make nodes with z = NaN transparent. For any of these choices, you may force a monochrome image by appending the modifier +m.
contourpen (str) – Draw contour lines on top of surface or mesh (not image). Append pen attributes used for the contours.
meshpen (str) – Sets the pen attributes used for the mesh. You must also select -Qm or -Qsm for meshlines to be drawn.
facadepen (str) – Sets the pen attributes used for the facade. You must also select -N for the facade outline to be drawn.
