Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Skeletal animation of objects made only of vertices

I was wondering if someone already managed to do skeletal animation of objects that do not have a single poly.

I have a cloud of point that I wish to deform in real time, it's for some data visualization stuff.

Importing it as an FBX is not possible because it crashes UE.

But maybe someone managed it via scripting?

Thanks for any hints.

Instead of only 'importing' vertices, you could try importing it as a connected mesh using polygons, and then writing a shader to display only the vertices.

I realize this is Unity, but it might be useful for reference: http://forum.unity3d.com/threads/pointcloud-shader-shader-that-renders-a-single-pixel-per-vertex-possible.113473/

Thanks for the answer. Google did not return anything, so maybe it's how I phrased it...

The links give interesting ideas. I will be looking at how I can apply them to my problem.
