Attributes

`animation_manager`	This mob's scene-owned animation manager.
`basis`	The Mob's orientation and scale, as a flattened 3x3 matrix of shape `(*, 9)`.
`casts_shadows`	Whether this Mob's geometry blocks light on its way from a light source to another surface -- whether it casts a shadow.
`children`	The Mobs attached below this one, in attachment order.
`closed_shell`	Whether this Mob's triangles form a CLOSED shell -- every camera ray that enters the geometry crosses a second time on its way out.
`draws_descendants`	Whether `get_render_primitives` returns geometry belonging to this Mob's DESCENDANTS as well as its own.
`forward`	Get the direction the Mob is facing.
`lifespan`	This mob's [spawn, despawn) interval on its Scene timeline (a `Lifespan`).
`location`	The Mob's position in world space, shape `(*, 3)`.
`normalized_basis`	The Mob's orientation with scale divided out, shape `(*, 9)`.
`parents`	The Mobs this one is attached to, in attachment order.
`receives_shadows`	Whether this Mob's surfaces are darkened by shadows cast onto them.
`right`	Get the Mob's own rightward direction.
`scale_coefficient`	The Mob's scale along its own right, up and forward axes, shape `(*, 3)`.
`two_sided`	Whether this Mob's geometry should be lit from whichever side the ray arrives on.
`up`	Get the Mob's own upward direction.
`x`	The Mob's x coordinate in world units, shape `(*, 1)`.
`xy`	The Mob's x and y coordinates in world units, shape `(*, 2)`.
`y`	The Mob's y coordinate in world units, shape `(*, 1)`.
`z`	The Mob's z coordinate in world units, shape `(*, 1)`.

Parameters:: stroke_width (int)

draws_descendants = True¶: Whether get_render_primitives returns geometry belonging to this Mob’s DESCENDANTS as well as its own. Almost nothing does: a BezierCircuitCubic or a Surface draws its own rows and leaves its children to draw themselves. Polyhedron is the exception – it gathers every face under one _mesh_key – and the difference decides two things for become(): whether the Mob is one morph unit or several, and whether a descendant may be published to the Scene in its own right (doing so under an aggregator draws it twice, and draws geometry the aggregator deliberately omits, such as a Polyhedron’s vertex-and-edge graph).

get_render_primitives()[source]¶: Build the native sphere primitives representing this point cloud.
