Material-effect folding: classifying what operations removed.

Assemblers emit MaterialEffects alongside their Ops — a unified description of the material they remove, for CNC and laser alike. fold_effects() aggregates the effects of many operations against one stock into an immutable MaterialState snapshot: through-cut voids, the burn surface map, provenance, and escalation signals for geometry the current profiles cannot represent exactly.

RasterEffect​

A raster material effect: an R8 power map plus its grid placement.

cut_power_threshold​

cut_power_threshold: Optional[int]

Raster power at or above which the material is cut through.

origin_mm​

origin_mm: tuple[float, float]

World-mm origin of the grid's (0, 0) pixel corner.

power​

power: compressed_array.CompressedArray

The power map as a compressed R8 array.

px_per_mm​

px_per_mm: tuple[float, float]

Grid density in pixels per millimetre (x, y).

VectorEffect​

A vector material effect: polygons removed over a Z interval.

Z values use the toolpath convention (stock surface at z = 0, bottom at z = -thickness): z_from=None means open to the surface, z_to=None means through the bottom.

polygons​

polygons: list[list[tuple[float, float]]]

Footprint polygons in workpiece-local mm.

z_from​

z_from: Optional[float]

Top of the removed interval; None = open to the surface.

z_to​

z_to: Optional[float]

Bottom of the removed interval; None = through the bottom.

VolumeEffect​

A volume material effect: closed solids to be removed.

No assembler emits these yet; the variant exists so future 3D assemblers join the same fold without a wire-format change.

positions​

positions: list[tuple[float, float, float]]

Vertex positions of the first solid (world mm).

triangles​

triangles: list[tuple[int, int, int]]

Triangle indices of the first solid.
