<p>The Trail POP captures and retains all the points of the input for the most recent N frames or N "slices", being a time-history of the input's points. It then optionally creates primitives that connects the points in various ways.
</p><p>If the number of points of the input is the same for all the slices, then it can easily skin points together using the Connectivity menu, such as maling a line strip for each point over time.
</p><p>If the number of points is changing per-frame, as it would with a particle system, it can still connect time-related dots by using an <code>Id</code> attribute on the points, and making sure the Id of a particle stays the same through its life. You can select which attribute it co-relates to using the Match by Attribute parameter.
</p><p>It ignores and does not use the connectivity (primitives) of the input.
</p><p>If the number of points of the input is the same for all the slices, it adds one new <a href="/Dimension" title="Dimension">Dimension</a> whose size is the number of slices.
</p><p>Trail Length can be expressed in Seconds or Frames. Seconds is preferable as it will remain the same if you move the Trail POP to another project with a different frame rate. Trail Increment lets you skip frames - capture a slice every Mth frame.
</p><p>Reset clears and restarts the trail. Oldest <span class="mw-lingo-term" data-lingo-term-id="2a3cd5946cfd317eb99c3d32e35e2d4c">Point</span> First reverses the order of the slices.
</p><p>The Trail POP deals with frame drops elegantly by (optionally) filling in data for missing frames and creating stand-in slices, and (optionally) tagging each slice with an <code>Age</code> attribute. This can give smoother frame-drop-resistant trail curves.
