_styling

Immutable default render-kwargs dictionaries for each pyvisual render type.

Every constant in this module is a MappingProxyType (read-only view of a dict), preventing accidental mutation of package-level defaults at runtime. Caller-supplied keyword arguments are merged on top of these defaults using the | operator, so any key can be overridden without modifying the originals.

The constants fall into two groups:

Coloring defaults — merged before geometry kwargs when data arrays are present or absent:

• SOLID_COLOR_KWARGS — used when no scalar data is supplied (solid color).

• COLORMAP_KWARGS — used when scalar data is supplied (colormap render).

Geometry defaults — merged after the coloring defaults to fix render-style flags that depend on the geometry type (points, splines, slices):

• PLOT1D_KWARGS, PLOT2D_KWARGS

• POINTS_KWARGS, SPLINES_KWARGS, SLICES_KWARGS

Fieldline-specific defaults:

• FIELDLINE_KWARGS — baseline colormap limits for fieldline scalars.

• FL_POLARITY_COLORING_DEFAULTS — five-category polarity colormap.

• RANDOM_COLORING_DEFAULTS — random per-fieldline hue assignment.

Attributes

COLORMAP_KWARGS	Base PyVista kwargs applied when rendering geometry with scalar data.
FIELDLINE_KWARGS	Default colormap discretisation and limits for fieldline scalar data.
FL_POLARITY_COLORING_DEFAULTS	Full PyVista kwargs for polarity-colored fieldline rendering.
FL_STATE_ANNOTATIONS	Scalar-bar annotations for the five magnetic fieldline polarity states.
PLOT1D_KWARGS	Default render-style kwargs for 1-D line geometry (tube rendering).
PLOT2D_KWARGS	Default render-style kwargs for 2-D surface geometry (flat surface rendering).
POINTS_KWARGS	Default render-style kwargs for point-cloud geometry (sphere glyphs at each point).
RANDOM_COLORING_DEFAULTS	PyVista kwargs for randomly hue-assigned fieldline rendering.
SLICES_KWARGS	Default render-style kwargs for 2-D slice geometry (flat surface, no tube/sphere glyphs).
SOLID_COLOR_KWARGS	Base PyVista kwargs applied when rendering geometry without scalar data.
SPLINES_KWARGS	Default render-style kwargs for spline/line geometry (tube rendering).
