# Module Reference
|
|
|
|
This file provides a mapping of modules to their primary responsibilities and key symbols.
|
|
|
|
## Root
|
|
|
|
- `__init__.py`:
|
|
- **Entry Point**: Extension registration (`register`, `unregister`).
|
|
- **Node Tree**: `SLICETREE_NodeTree` class.
|
|
- **Sockets**: Definitions for all `SLICESOCK_*` classes.
|
|
- **Nodes**: Definitions for all `SLICENODE_*` classes.
|
|
- **Evaluation Engine**:
|
|
- `resolve_input()`: Recursively evaluates linked sockets.
|
|
- `_resolve_output()`: Computes node outputs with a caching system (`_EvalCache`) to avoid redundant calculations.
|
|
- `_follow_reroute()`: Handles Blender's Reroute nodes during evaluation.
|
|
|
|
- `registry.py`:
|
|
- **Auto-Registration**: Utility to track classes decorated with `@register_class`.
|
|
|
|
- `blender_manifest.toml`:
|
|
- Metadata for the Blender Extension platform.
|
|
|
|
- `pyproject.toml`:
|
|
- Standard Python project configuration.
|
|
|
|
## `/core` (Geometry & Slicing)
|
|
|
|
- `slice.py`:
|
|
- `slice_at_range()`: Top-level slicing function that iterates through Z-heights.
|
|
- `slice_at_z()`: Vectorized plane-mesh intersection using NumPy.
|
|
- `align_path_seam_sharpest()`: High-performance vectorized heuristic that positions the start vertex (seam) of closed polygon loops at the sharpest concave angle (inner corner), with fallback to sharpest angle overall.
|
|
- `SlicePaths.align_seams()`: Method on `SlicePaths` to align path seams to sharpest concave angles while preserving per-vertex attributes and metadata.
|
|
- `Pather`: Class that converts toolpaths into G-code strings. Supports per-segment extrusion rates, feedrates, and custom extra attributes.
|
|
- `segments_to_slice()`: Utility to convert raw intersection segments into continuous paths (closed polygons are processed via Pyclipper, open paths remain open).
|
|
- `link_segments()`: Logic for joining loose segments into continuous paths.
|
|
- `buffer_slice()`: Offset utility using PyclipperOffset. Supports rotated offsetting.
|
|
- `infill_slice()`: Generates rotated grid or rectilinear infill patterns, ensuring layer-to-layer consistency.
|
|
- `boolean_slice()`: Performs 2D boolean operations (Union, Intersection, etc.) on slice sets.
|
|
|
|
- `geometry.py`:
|
|
- Geometry utility functions.
|
|
|
|
## `/infra` (Blender Integration)
|
|
|
|
- `blender_mesh_capture.py`:
|
|
- `SlicingObject`: Represents a single mesh as a NumPy triangle array.
|
|
- `capture_mesh_edges()`: Extracts edges from a Blender mesh for path-based workflows. Supports capturing extra per-vertex attributes.
|
|
|
|
- `blender_slice_nodes_generic.py`:
|
|
- Base classes for NodeSlicer nodes (`SliceNode`) and sockets (`SliceNodeSocket`).
|
|
- Core evaluation logic (`resolve_input`).
