New Find Shortest Path node in Animation Nodes in Blender - Tutorial

12

3DSinghVFX writes:

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 :)

I've been using Blender since 2018 and have acquired substantial knowledge in Blender as well as other software like Gimp and Blackmagic Fusion. My areas of interest and expertise lie in Procedural Art, Motion Graphics, VFX, and Node-based effects, particularly with tools like Geometry Nodes, Shader Nodes and Animation Nodes.

  1. 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.

  2. Thank you so much. May I ask how you archieve the effect of that point growing along the spline on one of your examples?

      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).
