The IsValid property of the HalfEdgeMesh.VertexHandle class is a boolean property that indicates whether the vertex handle is valid. This property is useful for checking the integrity of a vertex handle within a half-edge mesh structure, ensuring that operations on the mesh are performed on valid vertices.
Use the IsValid property to verify if a VertexHandle instance is valid before performing operations that require a valid vertex. This can help prevent errors and ensure the stability of mesh operations.
// Example of using the IsValid property
HalfEdgeMesh.VertexHandle vertexHandle = new HalfEdgeMesh.VertexHandle();
if (vertexHandle.IsValid)
{
// Perform operations on the valid vertex handle
// Example: Accessing the edge associated with the vertex
HalfEdgeMesh.HalfEdgeHandle edge = vertexHandle.Edge;
// Further operations...
}
else
{
// Handle the invalid vertex case
// Example: Log an error or attempt to correct the mesh
}
