   * counterClockwise - given three points (defining a triangle), the winding is determined. 1 if counter-clockwise, -1 if clockwise and 0 if the points define a line.
   * pointInsideTriangle - calculates if a point is inside a triangle.
  -* sphericalToCartesian - converts a point from link:http://en.wikipedia.org/wiki/spherical coordinates[spherical coordinates] to link:http://en.wikipedia.org/wiki/cartesian coordinates[cartesian coordinates].

  === Usage
  
  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.
  
  
  === Example 1 - Creating a Triangle
  
negative.code: 
  jME defines the Plane as ax + by + cz = -d. Therefore, during creation of the plane, the normal of the plane (a,b,c) and the constant d is supplied.
  
  The most common usage of Plane is <<jme3/advanced/camera#,Camera>> frustum planes. Therefore, the primary purpose of Plane is to determine if a point is on the positive side, negative side, or intersecting a plane.
  
  Plane defines the constants:
