Interface LineOptions<M>

Initial Renderable.castShadow; defaults to true (§69).

Initial Node.clip; defaults to false (§67).

Here rather than on a Node options record because a clip is only meaningful on a node that draws — the mask is the node's own geometry — and this is the options record every drawable funnels through. It is also what gives the §79 readers one spelling for the field beside the three §49 flags above.

Initial Renderable.frustumCulled; defaults to true (§87).

Surface appearance (§57). Required unless a §58 object paint derives one — a shape without either draws nothing, and that mistake is refused at construction (§85) rather than hidden behind an invisible node.

The two states are exclusive, both ways (§85, refused loudly):

• material, no object paint — R-16's tier: solid paints travel as per-vertex colour through this material, which must multiply them (vertexColors: true).
• object paint, no material — the paint-object tier: the shape derives a §60 NodeMaterial from its paints and wears it as Renderable.material (typed by M, which stays at its default — the derived material is the one place the family's parameter is wider than its type; see Paint). Passing a material and an object paint is refused: the material would be silently ignored, which is "accepted and ignored" wearing a disguise.

§50's example writes fill: "#4466ff" instead of a material, and at the solid tier that stays unsupported for R-16's recorded reasons (an invented material is an undisclosed §83 liability and §79 has no key for it). At the object tier both objections dissolve — the derived material owns nothing the application must dispose, and §79 writes the paint itself — which is exactly why the object tier is spelled without a material.

Initial Renderable.receiveShadow; defaults to true (§69).

Initial Renderable.renderLayer; defaults to 0.

Initial Renderable.renderOrder; defaults to 0.

Initial Renderable.scissor; defaults to null (§67).

A per-draw axis-aligned rectangle in drawing-buffer pixels. null (the default) leaves the view scissor alone, so existing scenes stay transcript-identical. See scissor.ts.

Initial Shape2D.tolerance in world units; defaults to §51's DEFAULT_FLATTEN_TOLERANCE.
