TConvexHalfEdgeStructureData

Return true if we can support this convex, based on number of features and maximum index size.

Fill an array with plane indices for the specified vertex. Return the number of planes found.

Get a plane for the specified Edge (

edge index, not half-edge index) EdgeIndex must be in range [0, NumEdges()) EdgePlaneIndex must be 0 or 1 return value is in range [0, NumPlanes())

Get a vertex in the specified Edge (

edge index, not half-edge index) EdgeIndex must be in range [0, NumEdges()) EdgeVertexIndex must be 0 or 1 return value is in range [0, NumVertices())

HalfEdgeIndex must be in range [0, NumHalfEdges()) return value is in range [0, NumPlanes())

HalfEdgeIndex must be in range [0, NumHalfEdges()) return value is in range [0, NumVertices())

Get the next half edge on the same plane HalfEdgeIndex must be in range [0, NumHalfEdges()) return value is in range [0, NumHalfEdges())

The edge index of one of the bounding edges of a plane PlaneIndex must be in range [0, NumPlanes()) PlaneEdgeIndex must be in range [0, NumPlaneHalfEdges(PlaneIndex)) return value is in range [0, NumHalfEdges())

Get the index of one of the vertices bounding the specified plane PlaneIndex must be in range [0, NumPlanes()) PlaneVertexIndex must be in [0, NumPlaneVertices(PlaneIndex)) return value is in [0, NumVertices())

Get the previous half edge on the same plane HalfEdgeIndex must be in range [0, NumHalfEdges()) return value is in range [0, NumHalfEdges())

HalfEdgeIndex must be in range [0, NumHalfEdges()) return value is in range [0, NumHalfEdges())

VertexIndex must be in range [0, NumVertices()) return value is in range [0, NumHalfEdges())

Initialize the structure data from the array of vertex indices per plane (in CW or CCW order - it is retained in structure) If this fails for some reason, the structure data will be invalid (check IsValid())

Number of unique half-edges (no half edge's twin is in also the list). Should be NumHalfEdges/2.

The number of edges bounding the specified plane.

The number of vertices that bound the specified plane (same as number of half edges) PlaneIndex must be in range [0, NumPlaneHalfEdges(PlaneIndex))

Initialize the structure data from the set of vertices associated with each plane.

Iterate over the edges associated with a plane.

Iterate over the half-edges associated with a vertex (leading out from the vertex, so all half edges have the vertex as the root).

Every plane is bounded by a sequence of edges, and every edge should be shared by two planes.

A plane of a convex hull.

A vertex of a convex hull.
