public interface ITopology

Properties

ConstrainedEdges

IEnumerable<(int, int)> ConstrainedEdges { get; }

Property Value

IEnumerable<(int, int)>

EdgeHitTestDistance

float EdgeHitTestDistance { get; set; }

Property Value

float

Faces

IEnumerable<TopologyFace> Faces { get; }

Property Value

IEnumerable<TopologyFace>

FacesWithInfo

We need private information in Tangerine in order to show them to end user. In any other application there is no need to know inner information about topology.

IEnumerable<(TopologyFace, TopologyFace.FaceInfo)> FacesWithInfo { get; }

Property Value

IEnumerable<(TopologyFace, TopologyFace.FaceInfo)>

VertexHitTestRadius

float VertexHitTestRadius { get; set; }

Property Value

float

Vertices

List<Vector2> Vertices { get; }

Property Value

List<Vector2>
