The GetFacesConnectedToVertex method retrieves all the faces that are connected to a specified vertex in a polygon mesh. This method is useful for understanding the topology of the mesh and for operations that require knowledge of the faces surrounding a vertex.
To use this method, you need to provide a vertex handle, which identifies the vertex in the mesh, and an output list that will be populated with the face handles connected to that vertex. The method returns a boolean indicating whether the operation was successful.
// Example usage of GetFacesConnectedToVertex
PolygonMesh mesh = new PolygonMesh();
HalfEdgeMesh.VertexHandle vertexHandle = ...; // Obtain a vertex handle from the mesh
List<HalfEdgeMesh.FaceHandle> connectedFaces = new List<HalfEdgeMesh.FaceHandle>();
bool success = mesh.GetFacesConnectedToVertex(vertexHandle, out connectedFaces);
if (success)
{
foreach (var face in connectedFaces)
{
// Process each connected face
}
}
else
{
// Handle the case where no faces are connected or an error occurred
}
