<h2>Static smooth curves</h2>
|
|
<div style="width:700px; font-size:14px; text-align: justify;">
|
|
All the smooth curves in the examples so far have been using dynamic smooth curves. This means that each curve has a
|
|
support node which takes part in the physics simulation. For large networks or dense clusters, this may not be the ideal
|
|
solution. To solve this, static smooth curves have been added. The static smooth curves are based only on the positions of the connected
|
|
nodes. There are multiple ways to determine the way this curve is drawn. This example shows the effect of the different
|
|
types. <br /> <br />
|
|
Drag the nodes around each other to see how the smooth curves are drawn for each setting. For animated system, we
|
|
recommend only the continuous mode. In the next example you can see the effect of these methods on a large network. Keep in mind
|
|
that the direction (the from and to) of the curve matters.
