		points -- [page:Array] of [page:Vector3]s 
		i0 -- [page:Integer] index 
		i1 -- [page:Integer] index 
		i2 -- [page:Integer] index
		
		
		Sets the triangle's vectors to the vectors in the array.
		
		[method:Triangle set]([page:Vector3 a], [page:Vector3 b], [page:Vector3 c]) [page:Triangle this]
		
		a -- [page:Vector3] 
		b -- [page:Vector3] 
		c -- [page:Vector3]
		
		
		Sets the triangle's vectors to the passed vectors.
		
		[method:Vector3 normal]([page:Vector3 optionalTarget])
		
		optionalTarget -- Optional [page:Vector3] target to set the result.
		
		
		Return the calculated normal of the triangle.
		
		[method:Vector3 barycoordFromPoint]([page:Vector3 point], [page:Vector3 optionalTarget])

		Return the area of the triangle.
		
		[method:Vector3 midpoint]([page:Vector3 optionalTarget])
		
		optionalTarget -- Optional [page:Vector3] target to set the result.
		
		
		Return the midpoint of the triangle. Optionally sets a target vector.
		
		[method:Boolean equals]([page:Triangle triangle])
		
		triangle -- [page:Triangle]
		
		
		Checks to see if two triangles are equal (share the same vectors).
		
		[method:Plane plane]([page:Plane optionalTarget])
		
		optionalTarget -- Optional [page:Plane] target to set the result.
		
		
		Return a [page:Plane plane] based on the triangle. Optionally sets a target plane. 
		
		[method:Boolean containsPoint]([page:Vector3 point])
		
		point -- [page:Vector3]
		
		
		Checks to see if the passed vector is within the triangle.
		
		[method:Triangle copy]([page:Triangle triangle])
		
		triangle -- [page:Triangle]
		
		
		Copies the values of the vertices of the passed triangle to this triangle.
