WebFigure 5 shows a parameter (polygon) and illustrates the Finding Parameter Settings sub-themes. We can imagine an algorithm that evaluates the roundness of the shape as our model. With Manual/Unconstrained, the parameter may be edited at will, thus taking any setting. As a result, any shape is possible. WebDetails.
