**Inheritance:**
java.lang.Object
```
public final class PolygonBuilder
```

A helper class to build polygon for [Mesh](../../com.aspose.threed/mesh) **Example:**

```
Mesh mesh = new Mesh();
  PolygonBuilder builder = new PolygonBuilder(mesh);
  builder.begin();
  builder.addVertex(0);
  builder.addVertex(1);
  builder.addVertex(2);
  builder.end();
```

Equals to :

```
Mesh mesh = new Mesh();
  int[] indices = new int[] {0, 1, 2};
  mesh.createPolygon(indices);
```

If all indices are ready to use, [Mesh](../../com.aspose.threed/mesh) is preferred, otherwise [PolygonBuilder](../../com.aspose.threed/polygonbuilder) would be a better choice.
