Syntax
public sealed class PolylineF : LicensedBaseConstructors
| Name | Description |
|---|---|
| PolylineF() | Creates an empty polyline. (Invalid) |
| PolylineF(Vector3[]) | Creates a polyline and automatically checks if it is closed. |
| PolylineF(Vector3[], bool) | Creates a polyline with the given vertices and explicit closedness. |
| PolylineF(ReadOnlySpan<Vector3>) | Creates a polyline and automatically checks if it is closed. |
| PolylineF(ReadOnlySpan<Vector3>, bool) | Creates a polyline with the given vertices and explicit closedness. |
Fields
| Name | Description |
|---|---|
| ClosedEpsilon | Tolerance for determining if the polyline is closed (distance between first and last vertex). |
Properties
| Name | Description |
|---|---|
| Count | Number of vertices. |
| First | First vertex of the polyline. |
| IsClosed | Indicates if the polyline is closed (the last vertex connects to the first). |
| IsValid | Valid if there are at least two vertices. |
| this[int] | Indexing into the polyline vertices. |
| Last | Last vertex of the polyline. |
| Length | Total length (perimeter if closed). |
| Vertices | Read-only view of the vertices. |
Methods
| Name | Description |
|---|---|
| Add(in Vector3) | Appends a vertex to the end of the polyline, updating length and closedness. |
| AddRange(ReadOnlySpan<Vector3>) | Appends multiple vertices to the end of the polyline, updating length and closedness. |
| AsReadOnlySpan() | Returns the vertices as a ReadOnlySpan<T> for efficient access without allocations. |
| AsSpan() | Returns the vertices as a Span<T> for efficient access without allocations. |
| Clear() | Clears all vertices, resetting the polyline to an empty state. |
| GetBounds() | Computes the axis-aligned bounding box (AABB) of the polyline. |
| InsertAt(int, in Vector3) | Inserts a vertex at the specified index, updating length and closedness. |
| Recompute() | Recomputes the length and closedness of the polyline from its vertices. |
| RemoveAt(int) | Removes the vertex at the specified index, updating length and closedness. |
| ToArray() | Returns a copy of the vertices as a new array. |
