mixins

Mixin classes that compose the four functional areas of Plot3d.

All four mixins are defined in this module and are assembled into Plot3d via multiple inheritance.

Mixin responsibilities

ObserverMixin

Camera and observer controls in spherical coordinates — position, focal point, up vector, position angle, line-of-sight FOV, and a live camera-state readout.

GeometryMixin

Solar geometry primitives — Sun sphere, spherical shells, planar discs, longitude/latitude grid lines, and the Thomson sphere.

GridMeshMixin

Structured-grid rendering from independent 1-D or pre-broadcast 3-D coordinate arrays: 1-D line slices, 2-D surface slices, 3-D volume slices, and isosurface contours.

StackMeshMixin

Rendering from stacked N-D coordinate arrays (all axes share the same shape): single points, point clouds, single splines, spline bundles, magnetic fieldlines, and free-form surfaces.

Common patterns

Methods in GridMeshMixin and StackMeshMixin that accept r, t, p positional arguments are decorated with parse_mesh_params(), which promotes scalar inputs to 1-D arrays before the method body runs.

Keyword arguments are passed through to add_mesh() by merging stylistic defaults from pyvisual.core._styling with caller-supplied overrides.
