### Example 


To add a polygon in mesh:

```python
from aspose.threed.entities import Mesh

mesh = Mesh()
indices = [0, 1, 2]
mesh.create_polygon(indices)

```

Travel through all polygons in mesh:

```python
from aspose.threed.entities import Mesh

mesh = Mesh()
for polygon in mesh:
    pass

```
