The IsValid property of the HalfEdgeMesh.HalfEdgeHandle class is a boolean property that indicates whether the current half-edge handle is valid. A valid handle typically means that it references a valid half-edge within the mesh structure, as opposed to an uninitialized or invalid state.
Use the IsValid property to check if a HalfEdgeHandle is valid before performing operations that require a valid handle. This can help prevent errors or exceptions that may occur when attempting to access or manipulate invalid half-edges.
// Example usage of the IsValid property
HalfEdgeMesh.HalfEdgeHandle edgeHandle = someMesh.GetHalfEdgeHandle();
if (edgeHandle.IsValid)
{
// Proceed with operations on the valid half-edge
var vertex = edgeHandle.Vertex;
// Additional operations...
}
else
{
// Handle the invalid state
// Perhaps log an error or attempt recovery
}
