Polyface

A Polyface is a mesh structure with arrays of points that are shared among multiple incident facets.

Classes

Name Description  
AuxChannel Represents a single PolyfaceAuxData channel.  
AuxChannelData Represents the AuxChannel data at a single input value.  
ClippedPolyfaceBuilders A pair of PolyfaceBuilder objects, for use by clippers that emit inside and outside parts.  
ConvexFacetLocationDetail Implementation of FacetLocationDetail for a convex facet.  
FacetFaceData Data for a face in a polyface containing facets.  
FacetIntersectOptions Options for computing and processing facet intersection methods.  
FacetLocationDetailPair A pair of FacetLocationDetail.  
FacetOffsetProperties  
FacetOrientationFixup  
IndexedEdgeMatcher An IndexedEdgeMatcher carries an array (edges) of edges start & end indices for sorting and subsequent analyses (such as testing for closed mesh)  
IndexedPolyface An IndexedPolyface is a set of facets which can have normal, param, and color arrays with independent point,  
IndexedPolyfaceSubsetVisitor An IndexedPolyfaceSubsetVisitor is an IndexedPolyfaceVisitor which only visits a subset of facets in the polyface.  
IndexedPolyfaceVisitor An IndexedPolyfaceVisitor is an iterator-like object that "visits" facets of a mesh.  
NonConvexFacetLocationDetail Implementation of FacetLocationDetail for a general facet, which may or may not be convex.  
OffsetMeshContext  
OffsetMeshOptions Options carrier for cloneOffset.  
Polyface A Polyface is an abstract mesh structure (of unspecified implementation) that provides a PolyfaceVisitor  
PolyfaceAuxData The PolyfaceAuxData structure contains one or more analytical data channels for each vertex of a Polyface, allowing the polyface to be styled  
PolyfaceBuilder * Simple construction for strongly typed GeometryQuery objects:  
PolyfaceClip PolyfaceClip is a static class gathering operations using Polyfaces and clippers.  
PolyfaceData PolyfaceData carries data arrays for point, normal, uv-parameters, and color, and index arrays for each.  
PolyfaceQuery PolyfaceQuery is a static class whose methods implement queries on a Polyface or PolyfaceVisitor provided as a  
SectorOffsetProperties Sector properties during offset.  
SortableEdge * For boundary sorting, an edge is a (packed!) Float64Array.  
SweepLineStringToFacetContext  
SweepLineStringToFacetsOptions Options carrier for sweeping linework onto meshes.  
TaggedNumericData Structure with 2 integer tags and optional arrays of integers, doubles, points, vectors, and geometry.  
TriangularFacetLocationDetail Implementation of FacetLocationDetail for a triangular facet.
