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"

Does HandeldARBP in UE4.19 support Vertical Planes and 2D Image Detection?

As per title, the new ARKit has some cool features like vertical plane detection and 2D images recognition. Are these features supported by the new HandHeldBP in UE4.19?

I checked the D_ARSession Config, and Plane Detection Mode only shows Horizontal Plane Detection, so this is a bit concerning, but I figured to ask the community since I'm at the beginning of my project and want to know if I should go either with Unreal or just swift+Xcode.

My app needs to distinguish things (windows, refrigerators, air conditioners, switches, etc.) and show messages in AR based on the thing being recognised, can I achieve that with Unreal? I thought about using 2d image recognition after a "training session"where I let the user take pictures of whatever he needs, but I am not sure if this is the best way to do this and if unreal can help.

That's a very important question I want to find answer to. Google ARCore doesn't support vertical planes, but ARKit 1.5 does. Is there any estimate for this feature to be added?

Same here, I need to detect some patern and get their positions in the world, apparently it is doable with unity ( https://blogs.unity3d.com/2018/02/16/developing-for-arkit-1-5-update-using-unity-arkit-plugin/ ), but I'm looking for a solution within Unreal Engine

ARCore 1.2 supports vertical plane detection. You need to download their custom fork for now but I'm guessing it will be implemented in the main engine version soon.

No, only horizontal planes supported. The Handheld AR template debug mode gives a good indication of what is supported.

I saw vertical plane detection working in UE4.20preview 3 with this same template but have not been able to get it working on iOS with the newer previews (app built with p4 & p5 crashes on start on device)
