Demo html/js not working

Question

Demo html/js not working

markstroeve opened this issue 13 years ago · comments

I've got the Chrome plugin working on my mac,I can use gestures.
Next i wanted to check out the basic JS demo which is included in the repository.

But this demo doesn't seem te be working. I keeps giving the default text (Kinect not connected).
And there seems to be no XHR or websocket traffic/connection .

Is the current demo broken?

Officially right now we only support the Safari plugin.

We are making efforts to port the Safari plugin to Chrome & Firefox (NPAPI).

Are you up for it?

I used the Chrome version. Because i couldn't get the Safari plugin/extension working.
I followed the instructions but when i want to build i get a lot of errors most of them are about missing includes/requires.
Do i need to add paths to NITE/OpenNi somewhere?

Indeed you do.
What are the errors that you get?

This is obviously a problem where the compiler can't find the OpenNI
includes.

Please download the binaries of Openni and Nite from the urls in the readme.
Run their installation scripts.
Then set Xcode to find the includes (the install puts them usually in
/usr/..).

I've installed the chrome extension and am getting the same error:

DepthJS Console

No Kinect / DepthJS detected

Is the chrome extension not supported?

I did receive several warnings when I compiled :

depthjs.cc:162: warning: ‘bool setupDevice()’ defined but not used
ocv_freenect.cpp: In function ‘void* ocvFreenectThread(void*)’:

Are these the problem? or is the chrome extension not supported as mentioned above?

@mairead
Please remove ocv_freenect.cpp and bg_fg_blobs.cpp from the build. They are
deprecated...
The errors should not bug you now :)

As for the missing Kinect, well.. make sure everything is connected.
I usually test everything by running an OpenNI already-compiled example...

@royshil

Thanks, will remove the deprecated libs. For clarification when I am trying to run the demo app I have already connected the kinnect and successfully run both the glview app and the chrome extension that displays the first and second blob views. These are all working. It is only the demo page in the developers API I can't see. I was going to try building the safari extension, to see if I had more luck with that instead unless you have a different suggestion?

I'm not sure what you mean when you say an already-compiled example of OpenNi

Roy Shilkrot · Answer 9 · Mon Jan 09 2012 21:18:15 GMT+0800 (China Standard Time)

@mairead
The demo app will actually not show anything on screen.. it's just an
example of the API.
You should be able to see stuff in the Javascript console though.

The OpenNI examples are indeed "glview" and the likes of that.
