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"

Performant network graphs in UE4


I am going to develop network graph tool for VR based on UE.

This tool is something like Gephi + Maltego -- it should give good visualizations also allowing selecting nodes/edges and performing through context menu some operations on them like collapsing/expanding nodes.

So, the problem is that I don't know how to implement graphs in UE efficiently. First of all, I suppose Blueprints aren't enough for this, C++ is needed with some properties and etc for editor.

As far as I know, the best way is to create mesh model: solid lines for edges and spheres or turned to camera sprites for vertices. After operations like collapsing nodes I should "hide" part of graph and remove it physically from the models. Is this performant enough? What are good ways to implement this in UE?

Also, how should I organize UI? Should I place some Unreal UI elements between camera and node? Or can I somehow detect that mouse/VR pointer is pointing to some node? How can it be done in UE?

Hola, llegaste a solucionar el problema. Me encuentro en la misma situación. Ya sea en UR4 o algun otro motor de Realidad Virtual
