-jME's Triangle class is a simple data class. It contains three <<jme3/vector#,Vector3f>> objects that represent the three points of the triangle. These can be retrieved via the `get` method. The `get` method, obtains the point based on the index provided. Similarly, the values can be set via the `set` method.
