Description
sp.contour_map3d() is the 3D twin of sp.contour_map(): all 3 contour-map variants share the same 3D form, selected with the same variant keyword. The scattered lats/lons/field samples are interpolated onto a regular grid (the same inverse-distance-weighted interpolation the 2D chart itself uses) and drawn as one column per cell, height and tone following the interpolated value there — a real density surface, not a scatter of points. extrema adds a tall marker at every local high and low the grid contains.
Variants
| Variant | Aliases | Uses | 3D form |
|---|---|---|---|
filled | bands, heat, basic, default | lats, lons, field | A full grid surface, one column per cell. |
isolines | lines, contour_lines, iso | lats, lons, field | The same grid surface as filled; the 2D chart’s stroked-line styling has no separate 3D form. |
extrema | highs_lows, hl, pressure_centers | lats, lons, field | The same grid surface plus a tall marker at every local high and low. |
Data
lats/lons position each sample and field gives its value; all three are interpolated onto the same regular grid regardless of variant.
3D planes
The viewpoint is independent from the variant: orientation3d picks the initial camera plane and applies to every variant; the view always stays draggable.
orientation3d="iso" — Isometric three-quarter view (default).orientation3d="horizontal" — Side-on view, almost at floor level.orientation3d="vertical" — Top-down view from above.orientation3d="front" — Front elevation, nearly flat.3D scenes
scene swaps the environment the columns are drawn in and applies to every variant and every plane.
scene="default" — Each series keeps its own categorical palette color, rendered as shaded 3D bars on a flat grid.scene="terrain" — The data is resampled onto a dense grid and rendered as hundreds of thin colormap-colored columns, forming a continuous mountain-of-bars terrain.scene="tower" — The data is resampled onto a dense field of round skyscraper-like towers instead of boxes, for a city-skyline reading of magnitude.scene="radial" — The data is resampled onto a dense polar grid of rings and wedges radiating from the center, like a 3D radar/sonar sweep of the value field.scene="podium" — The data is resampled onto a dense grid and quantized into stepped terrace levels, like a rice-terrace contour map, to read value bands at a glance.Themes
theme restyles the whole canvas (colour grade and glow) and applies to every variant, scene and plane.

The 3D zone (floor, walls, axes and camera) scales to the elements: its length, width and height follow the extents of the drawn blocks, a minimum floor depth keeps single rows readable, wide scenes are drawn flatter and the camera frames the whole box. The axis ticks read the real data range. Pass zone=[x, y, z] to force the proportions of the box instead; the longest side is normalised to 1.
