 --------------------------------
 
 In this example the arc length (distance to the first point on the line) is calculated in every vertex.
-Between the vertex and fragment shader that value is automatically interpolated for all points that will be visible on the screen.
-In the fragment shader the `sin` of the arc length is calculated.

+In the fragment shader the ``sin`` of the arc length is calculated.
 Based on the result a decision is made on whether the fragment should be drawn or not.
