Computer Graphics

Implementing functions to draw:

• Lines (Using Bresenham algorithm)
• Circles (Using Bresenham algorithm)
• Bezier Curves using the following steps:

  1. Receiving 4 points.

  2. Create 2 seperate vectors: first vector is from the points X's and second vector is from the points Y's.

  3. Multiply the vectors separately in bezier matrix to calculate a,b,c,d equation constants.

  4. Calculate a new point on the curve using the following polynomials:

        t values is between 0 and 1 (Taking smaller steps equals smoother bezier curve)
     

  5. Draw a line between the previous point and the new point.

  6. Increment t by the step size.

     Repeate steps iv ~ vi until t >= 1
