  • Field Details

    • m_pPoints

      public Vector<CAAMPoint> m_pPoints
      The point vector from which the triangle is defined.

    • m_v1

      private int m_v1
      Index to point 1.

    • m_v2

      private int m_v2
      Index to point 2.

    • m_v3

      private int m_v3
      Index to point 3.

    • m_dD

      private double m_dD

  • Constructor Details

    • CAAMTriangle

      public CAAMTriangle(int _v1, int _v2, int _v3, Vector<CAAMPoint> pPoints)
      Constructor
      Parameters:
      _v1 - first point index
      _v2 - second point index
      _v3 - third point index
      pPoints - point vector for triangle

    • CAAMTriangle

      public CAAMTriangle()
      Constructor

  • Method Details

    • assign

      public void assign(CAAMTriangle tri)
      Assignment operator
      Parameters:
      tri - triangle reference.

    • Calc_dD

      public void Calc_dD()
      Cache function.

    • IsInside

      public boolean IsInside(CAAMPoint p)
      Returns true if the point 'p' is inside the triangle.
      Parameters:
      p - The point to test
      Returns:
      True if the point is inside, otherwise false.

    • IsInside

      public boolean IsInside(CAAMPoint p, double[] alpha, double[] beta, double[] gamma)
      Performs a hit test on the point p. If p is inside -- the position of p relative to the triangle is returned. The relative position is: p = alpha*p1 + beta*p2 + gamma*p3 Where p1-3 is the three points of the triangle.
      Parameters:
      p - The point to test alpha Relative x1 position. beta Relative x2 position. gamma Relative x3 position.
      Returns:
      True if the point is inside, otherwise false.

    • CenterPoint

      public CAAMPoint CenterPoint()
      Returns the center point of the triangle.
      Returns:
      center point

    • Area

      public double Area()
      Returns the area.
      Returns:
      The area.

    • V1

      public int V1()
      Returns index to point 1.
      Returns:
      index 1

    • V2

      public int V2()
      Returns index to point 2.
      Returns:
      index 2

    • V3

      public int V3()
      Returns index to point 3.
      Returns:
      index 3
