How to increase Trail POP behaivor

POPs

Hey there!

I am currently working on a project, where I am trying to visualize real ocean current data. To achieve this, I created a CSV file containing latitude and longitude coordinates that describe the ocean current trajectories. These points are then imported into TouchDesigner and visualized using a Trail POP. By combining a simple expression with a time attribute, each point moves along its predefined path across the globe, following the direction and movement of the real ocean currents.

Now to my problem: the file contains currently 2500 columns, as I had to reduce it down because otherwise the programm would crash. I am a bit unhappy with the look of it, as it is rather shorn. I want the trails of the currents to be longer and for there to be more mass generally.

Is there a way to create more points, that follow the same path from the given ones, without having to expand the CSV File?

Atttached a screenshot from my current setup.

I appreciate any help, thanks!

Hello @KRISANDERS

One thing you could try is to use a Particle POP to create points randomly over the surface, and use a Neighbor POP to get an average of the “current direction” a particle should take. In the Neighbor POP’s second input, you would feed all the points with their direction coming from your CSV file.

You should be able to get longer trails if you set a Life Expectancy and a Trail Length long enough on the Particle POP and the Trail POP.

Hey thank you so much for the response! Unfortunatly this doesnt seem to work, without the programm crashing :frowning:

If you’re willing to share your project or a simplified version that replicates the issue, I can check what’s happening.
