The FindFaceVertexConnectedToVertex method in the PolygonMesh class is used to find a half-edge that connects a given vertex to a specified face. This method is useful when you need to determine the specific edge that links a vertex to a face within a half-edge mesh structure.
To use the FindFaceVertexConnectedToVertex method, you need to provide two parameters:
hVertex: A HalfEdgeMesh.VertexHandle representing the vertex you are interested in.hFace: A HalfEdgeMesh.FaceHandle representing the face you want to check for a connection to the vertex.The method returns a HalfEdgeMesh.HalfEdgeHandle that represents the half-edge connecting the specified vertex to the face. If no such connection exists, the method may return a default or invalid handle, depending on the implementation.
// Example usage of FindFaceVertexConnectedToVertex
PolygonMesh mesh = new PolygonMesh();
HalfEdgeMesh.VertexHandle vertexHandle = ...; // Obtain a vertex handle
HalfEdgeMesh.FaceHandle faceHandle = ...; // Obtain a face handle
HalfEdgeMesh.HalfEdgeHandle edgeHandle = mesh.FindFaceVertexConnectedToVertex(vertexHandle, faceHandle);
if (edgeHandle.IsValid())
{
// The edgeHandle is valid, meaning there is a connection
// between the vertex and the face.
}
else
{
// No connection exists between the vertex and the face.
}
