问题 The ARCore AugmentedImage example application that comes with the Unity SDK package places a picture frame around the sample images included in the sample AugmentedImageDatabase. It will place a picture frame around multiple images in the scene if they are found, and only destroy the picture frames once tracking is lost entirely. Suppose you wanted to only display a picture frame around the image most recently recognized - and remove the frame from the previous image? Checking the

问题 I'm hoping to learn and dedicate serious amount of time on building 3D augmented reality apps since they are slowly but surely becoming the future for human and computer interaction. I wish to learn ARCore but it only runs on limited number of brand new phones, it's not possible for me to test with, due to their prices,for now. I have few questions regarding to ARCore How is ARCore performence compared to other popular frameworks? Does it use extensive resources for simple operations such as

问题 When I went through the video for session 805, Creating Great AR Experiences, and they mention using screen space text when displaying text in AR. They use the example of their Measure app that works quite well. I want to achieve similar functionality. But, I am not able to figure it out. 回答1: Screen Space is the 2D pixel coordinate system of your display. It's where you normally do things like laying out UIKit widgets in screen space, etc. The alternative to Screen Space is a 3D coordinate

问题 The company I work is building an android application with vuforia(version 5.x) and Unity3D(version 5.3.5f1 Personal) integration. In newest android devices the camera is opening ok but We're facing problem in older devices like Samsung Galaxy S2(4.1.2). When the device open the camera via vuforia the screen is black and if we try to take a picture the image is obviously black as well. My activity is only instantiating the unity player and it is like code below: public class MainActivity

问题 I am creating a cylinder object using Reality Composer. My requirement is to wrap the cylinder with custom image. Image is dynamically created by the app. I have tried following approach and so far it's not working. After loading the anchor from Experience. Fetch model entity from anchor. Fetch model component from model entity. Add or edit material. Code: // Load the "anchor" scene from the "Experience" Reality File let anchor = try! Experience.loadAnchor() // Add the anchor to the scene

问题 I am creating a hybrid mobile application using jQueryMobile and phonegap. Now I need to implement the augmented reality in camera view to the application. I got wikitude for this purpose. Can I do the functionality mentioned in the following link using hybrid mobile application? http://www.wikitude.com/showcases/active-website-augments-real-estate/ I got some sample application here https://github.com/Wikitude/wikitude-phonegap/tree/master/Android But I am confused whether I can use this for

问题 Let's say I have a set of 5 markers. I am trying to find the relative distances between each marker using an augmented reality framework such as ARToolkit. In my camera feed thee first 20 frames show me the first 2 markers only so I can work out the transformation between the 2 markers. The second 20 frames show me the 2nd and 3rd markers only and so on. The last 20 frames show me the 5th and 1st markers. I want to build up a 3D map of the marker positions of all 5 markers. My question is,
