问题 I have a node that the user can rotate via a pan gesture. The user can select either X, Y, or Z axis and pan, and the node will rotate around that axis. The Issue : The node's front is facing the camera. Let's say the user pans to the right and rotates the node around the Y axis. The node's front is now facing the right. If the user switches to the X axis and pans down, the node's front will rotate downward (or clockwise from the user's perspective) from it's initial right-facing orientation.

问题 I calculate the camera position of a SCNScene that is rendered in Vuforia. However the object is not staying fixed on the marker but jumping around when moving. The cube in the scene appears only orthographically, no matter how the device is moved around the sides cannot be seen. The camera position is calculated with every frame: // Get model view matrix Vuforia::Matrix44F modelViewMatrix = Vuforia::Tool::convertPose2GLMatrix(result->getPose()); // Convert to extrinsic matrix SCNMatrix4

问题 I had image detection working properly in ARKit 1.5, but in ARKit 2.0 whenever I launch my application it freezes after what looks like 1 frame of the camera.

I am using the Unity plugin and every time I change the fields under Image Tracking in the Unity AR Camera Manager script I seem to have this problem. Has anyone else experienced this? 回答1: This bug is occurred on below

问题 I have a Windows server 2016 vm on Azure and I am trying to do some work in Augmented Reality using Vuforia and Unity. An essential part of this is being able to use my webcam but once I am inside the VM it doesnt recognise my integrated webcam. I tried to connect a webcam through USB as well but this doesn't work either. Is this an impossible task...getting a server instance to recognise webcams on my laptop or is it actually possible? Any help would be appreciated. 回答1: You could achieve it

问题 I have a question about the way how to show simple 2d image on top of detected marker. I have followed some tutorial to show 3d model and it works fine. there is no problem with 3d. The problem starts when I want to add normal 2d object->sprite .

The original image on editor is placed then so far that it's difficult to find it. I would be

问题 I am done with 3d object scanning and detection with ARKit 2.0. I have scanned 3d object from all sides of object. Once 100% scanning is done then had given name to that object and then save that ARReference Object and image in document directory. Then on button click I am going to detect scanned object and display it’s name and image from document directory. Object get detected but it’s taking too much time to detect an object. I have gone through Apple document for best practices and
