I am using a Oculus DK2 (v0.8) and OSVR SDK. I'm having a problem getting the HMD to run/display anything.
The Oculus samples and the OSVR samples do work however, so the osvr_server seems to run fine.
My application itself renders a test scene just fine when not using a HMD.
I tried two approaches:
First, just creating a osvr context and creating a DisplayConfig object. This seems to work, but DisplayConfig::checkStartup() fails (I do this in a loop, calling update on the context when the checkStartup call is failing). I used the OpenGLSample.cpp as a guide for this
Second, I tried using a RenderManager, but the call to createRenderManager results in a crash within the RenderManager.dll. I get the same crash wether I create the graphics lib object myself or if I let the library create it.
I am quite stuck now, since the demos and examples do work, I have no idea where to look for the error on my side. Creating the context works, querying interfaces as well, but the crash with createRenderManager is beyond me.
Does anyone have any hints or ideas what the problem could possibly be?
Regards and thanks in advance

RenderManager should not crash during open. There have been a couple of bug fixes recently to avoid that happening, and the latest RenderManager binaries, libraries and header files are available with the SDK download from http://osvr.github.io/using/ along with updated copies of the example programs.
When something goes wrong in RenderManager, it usually reports that to standard error. We're moving that to a logging interface, but for now it should show up on the console. Posting an output of that as an issue at https://github.com/sensics/OSVR-RenderManager/issues is a good way to let the developers know that there is a problem. Of course, providing the same sort of information you provided here will be helpful as well.

Thanks in advance.
We have to use HERE map's Turn by turn navigation feature in one of our Flutter application, we have added billing in the developer account and have created the necessary keys.
When we try HERE map examples they have provided, we get everything except maneuver instructions that shows the user when to turn right/left/go straight for some distance etc.
I'm new to this and I have no idea how to get this, we never get events on the listener and it only shows updating there, am I missing something ?
this is how it looks right now, Updating...
I think we should be getting the progress here, but we are not getting it here...
_visualNavigator.routeProgressListener = Navigation.RouteProgressListener((routeProgress) { }
Please look into the provided example app. It shows here how to get the maneuver actions.
Your screenshot shows a different app, so make sure everything works with the example app, at first. The app offers to run a simulation mode. This should work. If you run the example app with real GPS updates, you may need to go outside and move to get location updates. This should also work.
If this still does not work, it could either mean that your device has an issue with getting GPS locations. Some iPads, for example, lack support. Or that you have disabled getting location updates. You can cross-check this when trying the positioning_app example from the same repository that shows how to get location updates.
A last point may be to clarify what events you get and what you miss: There are multiple event listeners providing real-time information during guidance - if you have only an issue with maneuvers, then most likely you can solve your issue by following strictly the code of the example app.
Note that previous HERE SDK versions, prior to HERE SDK 4.13.0, only provided empty maneuver instruction texts during guidance when they have been taken from the route instance. Make sure to take this information from the VisualNavigator instead.
I'm new here, so feel free to give tips where needed. I am running into trouble using the Unreal engine combined with the HoloLens 2.
I would like to access the special black/white cameras of the HoloLens, for tracking purposes. These are normally not accessible. However, they can be activated by using the “perceptionSensorsExperimental” capability. This should be possible, since it also works with Unity: https://github.com/doughtmw/HoloLensForCV-Unity
I have tried to add the capability in the Unreal Project Settings: Config\HoloLens\HoloLensEngine.ini” -> “+RescapCapabilityList=perceptionSensorsExperimental”. The project still builds as expected, but I noticed that it doesn’t matter what I add here. Even something random like “+abcd=efgh” doesn’t break the build.
However, if I add “+CapabilityList=perceptionSensorsExperimental”, I get “Packaging (HoloLens): ERROR: The 'Name' attribute is invalid - The value 'perceptionSensorsExperimental' is invalid according to its datatype 'http://schemas.microsoft.com/appx/manifest/types:ST_Capability_Foundation' - The Enumeration constraint failed.”. I conclude: 1.) I’m making the changes in the right file. 2.) The right scheme needs to be configured in order for “+RescapCapabilityList=perceptionSensorsExperimental” to work as expected.
My question is how do I add the right schema to my Unreal project? (like in the Unity example referenced above, which uses “http://schemas.microsoft.com/appx/manifest/foundation/windows10/restrictedcapabilities”), I cannot find any example and I cannot find any proper place to put it. Not in the settings, not in the xml/ini files. Clearly, I am missing something.
Any thoughts are much appreciated!
Updated. We released HoloLens-ResearchMode-Unreal plugin
I get SOAP_EMPTY using gsoap, I have searched for a long time and had no answer,SOAP_EMPTY is newly added to gsoap,and it seems I'm the unlucky guy to meet this problem.
Here is where my code come from:https://github.com/miibotree/ONVIF/blob/master/main.c
Now soap_call___tds__GetCapabilities will return code SOAP_EMPTY,I'm now using gdb to track this problem it seems that I need to set a valid soap->id to avoid this problem,but I'm a fresh guy with onvif and don't know how to set a valid soap->id,and now I'm reading various docs about onvif and trying to solve it.
Hope any guys could help me, sinch searching so many docs makes my eyes pain and I still haven't found the answer,thanks.
SOAP_EMPTY is a validation failure. This error indicates than an element/attribute is empty but is supposed to have content. For example an integer value should not be an empty string. The old error generated by older gSOAP releases in this case was SOAP_TYPE which was less informative. In either case, validation fails. The best way to find out is to use soap_print_fault() and soap_print_fault_location()` where the latter call shows the location in XML where the problem is. Our ONVIF testing with gSOAP did not reveal such an issue.
basically the title says it all. I'm working on a model that needs (there is no way around it) to load data from a website, parse it and pass it onto another block. I thought I could use an S-Function written in C++, which didn't properly work, then I tried to use webread()
which also didn't work in Simulink because I can't use extrinsic functions on the device this will run on.
I thought I could work around it by downloading the file externally and then reading it through fscanfbut it turned out that Matlab CODER doesn't support that as well.
After putting 2 1/2 days into this now, I'm asking myself whether it is even possible to do something like an HTTP Request through a Simulink block. That's why I went here to ask that question. Thanks for every answer!
I figured out a way to do it with a C++ S-Function by now.
I also created a GitHub Repo for it. If you're stuck with the same problem as I was, try to take a look at this. I'm pretty sure it will help you.
I am developing an android app where I have to train my app to recognize two images and four objects.I created one single database where I added all the images and objects target in vuforia developer site and created the unity package. Now neither image nor object is getting recognized.
Probably the problem is the same for objects and images.
I think you should share some more info about what your doing as well as some meaningful code implementing it.
W/O that, I would suggest:
verify that the database and trackables are loaded and active # runtime
if so, see in console that the trackables are tracked by Vuforia
if so, verify the code enabling your augmentations
Please confirm whether have run trough these steps already and what results you got. I can share some code and further tips once the issue is a little but more specific.
Regards
