What it models, and when not to use it

No hand-written part: this entry’s source has not been written (the docs walk counts it).

Settings

Setting	Type	Default	Dimension	Role	Default’s kind
radius	Annotated[mime.units.Quantity, Dimension(exponents=(1, 0, 0, 0, 0, 0, 0))]	{"required": true}	length (m)	physical	none

Each role and default’s kind is the entry’s setting_roles (mime.registry.SettingRole); a setting that declares none is required.

Capabilities

Generated from which of the optional methods of mime.registry.Geometry the kind implements; a consumer that needs one it lacks is refused when it plans, naming both.

Capability	What it gives	Used by	This kind
samples	surface samples by named patch, at a resolution the consumer chooses	the MRS; immersed-boundary markers	yes
area	the area of each patch	the samples’ weights	yes
mass_properties	volume and inertia at a density	the part resolver	yes
radial_reach	the hull’s radial reach about its axis	a body’s extent; contact on the hull	yes
family_parameters	the parameters of the family it is	a surrogate trained on one family	no
tangent	a tangent it declares at a surface point	a law anisotropic along it	no
native	its native form, one of USD’s own primitives	the stage writer	no
drawing	a drawing, tessellated at the writer’s resolution	the stage writer, for a kind with no native form	no
region_primitive	its regions as OpenMaterica’s primitives: exactly, or (a region with no end along an axis) clipped at the kind’s own length, or refused	OpenMaterica’s manifest and stage	no
reach	reach	not stated	yes
sampling	sampling	not stated	yes
support	support	not stated	no

native: none, so the stage writes it in MIME’s schema with its drawing.

placement: none: its own frame is the frame its settings are written in.

Run-time capabilities (signed distance, outward normal, nearest point) are its regions’ and surfaces’ shapes, listed below.

Nodes it builds

Builds no node of its own.

Gradient status

The derivative through this entry is piecewise_jump: not the exact derivative of what it computes everywhere.
