Hello,

Please find the Unity API documentation for the pre-10.0 Engine release (v9.8) here:

Thanks,

I am trying to a create a Unity app for Microsoft Hololens that allows users to view a printed circuit board and detect certain components (chips and capacitors) within the board and determine if they were installed with the proper orientation.

I am having trouble detecting any portions of the board smaller than the entire board (16 x 14.5 cm).  The chips and capacitors themselves have dimensions ranging from 1.5 x 2.5 cm to 0.7 x 0.3 cm respectively with small features like small circles or bands on the component that tell its orientation.

Hi, I need to load dataset from obb file because of the large dimension of my Android app (300 Mb).

With Vuforia 9.8, all was allright .... but with the new version (10.1) I receive this error: DATABASE_LOAD_ERROR. On Ios everything is fine.

Any help??

When tracking successfully, Vuforia would set camera and image target's gameobject position.

I want to merge them to one model view so that I can set camera position and rotation with zero and only modify position and rotation of gameObject.   

I get camera matrix that transforms from camera space to world space and another is gameObject matrix hat transforms from world space to local space.

my calculation like that:

I am writing a script for action due to Virtual button as below, but i am getting following error "VirtualButtonBehaviour' does not contain a definition for 'RegisterOnButtonPressed* and no accessible CS1061 extension method 'RegisterOnButtonPressed* accepting a first argument of type VirtualButtonBehaviour' Assembly-CSharp could be found (are you missing a using directive or an assembly reference?".

I have seen all articles and queries but i am not able to solve it. Please help

Hi,



I am trying to upgrade my Unity AR project to SDK10.0. I saw that many class are now deprecated. 

I used to use

VuforiaRenderer.Instance.Pause(true);

to pause the camera and view the AR object stably.

Since the method is no longer existed, I wonder if there are any alternative?



Thank you for reading the question, have a nice day.

We have a target image, its an A3 size piece of paper with a big image of the inside of a computer. We have a virtual computer model pop up. However with the image on the floor, the model seems to be too close to the arcamera. We have played with Near, Far and Field of View but none of these seem to help. 

Any ideas?

Hi!

We are currently in the process of updating an old unity project from unity 2019.4.13/vuforia  8.5.9 to unity 2020.3.17/vuforia 10.1.4.

Our app has different functions: one of them uses the normal phone front/back cameras, another uses the vuforia AR camera. We used to be able to disable the AR camera by disabling the VuforiaBehaviour:

Vuforia.VuforiaBehaviour.Instance.enabled = false;

Using Vuforia 10 however, does not seem to release the camera like it used to, making it unavailable to us.

Hello!

I have A4 format paper sheet with the image on it but it has a white blank rectangle to be filled with a sticker in future to complete the picture like a puzzle game.

Vuforia should detect this paper only once it's completed and should not if it has not filled yet zone.

Very basic solution is to track only that quad sticker so it will work only if it is already attached to the sheet. The problem is that this piece has too few feature points and has 1-2 stars as an augmentable rating.

Hello,

I use Unity 2021.1.16f and Vurforia 9.8.8.

My app works on Unity as well as 2 tablets (build and run, not distribution test on playstore yet) using Android 10 (Samsung Tab A7) and Android 7 (Samsung Galaxy Tab A 2016). But I have a black screen using my Oppo find x2 Neo having Android 11.

I checked the camera clipping and the change of Scripting Backend from "Mono" to "IL2CPP" but it's still black screen for the AR Camera...

Is there any other case of black screen on Android 11?

How can I make it work on Android 11?
