Module feature 

Sub-object (face/edge) topology for direct modeling.

CSG trees have no persistent face/edge identity: meshes are regenerated wholesale and carry no provenance. This module derives that identity analytically from the tree itself — faces are named per-primitive (FaceTag), leaves are addressed by structural LeafPaths, and geom evaluates rays/membership against the tree exactly, independent of the active render backend (mesh or SDF ray-march).

Modules

edge

Analytic edge resolution: turn a pair of leaf faces into a verified edge curve on the final solid, or a typed rejection.

geom

Analytic ray/membership evaluation of a DynamicObject tree.

lower

Lower an EdgeFeatureData into pure-CSG masks against its child.

Structs

EdgeFeatureData

Payload of an EdgeFeature node: which edges to feature and how. Edges are re-resolved against the current child geometry every evaluation, so the feature follows parameter edits; unresolvable edges are skipped.

EdgeSel

An edge, identified as the intersection curve of two faces. Stored in canonical (sorted) order so the same edge always compares equal.

FaceRef

A face of a specific leaf, addressed structurally (survives node-id churn and scene save/load).

LeafPath

Structural address of a leaf inside a subtree, independent of node ids.

Enums

EdgeFeatureKind

Which feature an EdgeFeature node applies to its edges.

FaceTag

A face of a supported primitive, named in the primitive’s local frame.
