I have added the new Find Shortest Path Node in the Animation Nodes + Extra Nodes for Blender. This node is based on Dijkstra's algorithm which is a single source. However, I have implemented it in such a way that it can not only handle the multiple-sources and a mesh that has multiple-islands. It can be used in many areas of CGI. Project files are available in the video description.
Happy Noding :)

Hello And thank you for the clear tutorial!
I'll download this version of Blender and try the new node!
Onde question about this video 0:05-0:11 sec. How did you do the glowing dot effect on the growing lines?
Kind regards,
Erik
You're welcome :)
I use curve's "Use UV for mapping" option in the Texture Space. Then in the shader, you separate the UVs into RGB, use one of the color(R) with the Color Ramp node to limit the emission to a point.
Thank you! I'll try this trick!
Hmmm not there yet.
I used 'Use for UV mapping' and seperated UV's into rgb..
Should I UV unwrap?
I tried it with ivy gen and a build modifier to animate growth.
The ivy grows in 100 frames and the final object has glowing tips. But the glowing effect doesn't move along the path's created by the Ivy Generator...
Or does this only work with the 'trim spline' node that you use?

It only works when you Trim the spline with Animation nodes or use option Curve Properties --> Geometry --> Bevel Start or End.
There is another way to achieve this with Animation Nodes is to put a custom object (e.g., Sphere) at the end of every curve (splines).
ps I'll try Animation Nodes too!
Thank you for the replies! I'll dive into this some more.
And thanks for the Animation nodes plugin! It seems daunting, but i'll take small steps.....
Mograph galore!
pps
I'll try the effect with Ivy Gen... Seems lie a nice challenge!
Do you think this should/could work? Ivy as an inout object, split btranches to individual curves and then trim... Or would all curves then start growing at the same time?...

I did not understand your question properly. In AN, you can split the branches into individual curves.
Thank you so much. May I ask how you archieve the effect of that point growing along the spline on one of your examples?
You're very welcome :)
