Description
A computational design approach to sagitta. The sagitta is the height of an arc — it is the perpendicular from the midpoint of the arc's chord to the arc itself.
The first step is to define the circle and the equation in a code block. The second step is to project the point determined by the sagitta height onto the circle.
Now that we have the arc determined, we can choose to move it to the center point of the circle. That way we can more easily control any derivation geometry.
Finally, the logic can be packaged into a custom node for reuse across Dynamo graphs.
