• On the left: the midpoint approximation quadratic - shared the ends and the midpoint with the original cubic Bezier
• On he right: the quadratic defined by the q₀, q₁ and q₂ expressed as a linear combination of the points defining the original cubic Bezier. Modify the values for the coeficients in the form above and press the "Apply" button.
  The midpoint approximation quadratic is defined by the {1, 0, 0, 0}, {-1/4, 3/4, 3/4, -1/4} and {0, 0, 0, 1} coefficients.

Both approximation shows the chart of the defect distance.
