This is the error that I am getting when I use multiple(~30 images) high resolution(4096 X 2048) textures with each image being around 5 MB on Nexus 5 android version 4.4.4.
E/Adreno-GSL﹕ <ioctl_kgsl_sharedmem_alloc:1532>: ioctl_kgsl_sharedmem_alloc: FATAL ERROR : (null)

I have several Images stored in my android app locally in the drawable-nodpi folder. And I change the texture of my sphere very often by calling the following function in VR app:-

public void changeImage(int imageResourceId) {

    Texture t = new Texture("sphereTexture", imageResourceId);
    t.shouldRecycle(true);
    ArrayList<Object3D> objectList = getCurrentScene().getChildrenCopy(); // Get reference to sphere

    Material material = objectList.get(0).getMaterial(); // get material of sphere
    for (ATexture texture : material.getTextureList()) {// remove previous texture on material
        material.removeTexture(texture);
        texture = null;
    }


    try {
        material.addTexture(t); // add new texture to material
    } catch (Exception e) {
        e.printStackTrace();
    }
}

So my question is, is it possible to get rid of this error? Is there any recommendation for using image textures like what is the right resolution for image textures etc.

Hello! We are developing an app using RajawaliVR. We implemented a first person camera, and we can also freely move in the scene (like fly or walk).

We would like to add to our first person camera a cursor (like in other VR apps), so we could interact with objects in our scene. The idea is that our cursor would look like a target and do a little animation when we look at an object, and after a short time it would trigger an action.

So the question is: is there currently an implemented cursor for RajawaliVR or is there a way to implement something like that?

Thanks in advance.

The RajawaliVRExample application provokes a crash within the Rajawali library when being resumed after a screen off pause. Here's the stack trace I experience on my Nexus5 on the L Developer Preview.

I've worked through the difficulties of this particular transition on another project, so I'm familiar with the trickery of the OpenGL Context being destroyed after screen off even when it's requested to be preserved. Perhaps that's the root issue here?

Love your work!

Accessing the SurfaceTexture in Java from MediaPlayer is not possible without using the new low level MediaCodec (API16). These are in flux and restrict deployment options. I also do not want to "go native".

A shader could handle rendering the left/right eye areas of the video to the left/right eye areas of the VR renderer.

From my research, it seems that the video surfacetexture can be passed to a fragment shader attached to the VideoTexture. SurfaceTexture even provides the transformationMatrix:

public void getTransformMatrix(float[] mtx)

I think I could do this with a raw (glsl) shader, but the new Rajawali shader framework should allow me to write the shader in java, yes? The framework generates and compiles the glsl?

Would this be the recommended way to VR render a 3D SBS video to a VideoTexture?

I downloaded the RajawaliVR project and it gives me two compile time errors in the class HotspotFragmentShader. Please fix it as soon as possible. Thank you :)

Hi.

I am trying to play a 3D video with RajawaliVR. To do that i need an already stereoscopic video and then split it in two and render them for each eye separately. However with the current implementation of the RajawaliCardboardRenderer, i cannot do that. I have tried to implement the CardboardView.Renderer, instead of the CardboardView.StereoRenderer in order to deal with the stereoscopic details, but i am getting nowhere. Can you help me? Are this kind of enhancements in your work list?

Thanks,
rbrilhante

I have extended RajawaliVRActivity and RajaWaliRenderer. Problem is that it is giving me a filenotfoundexception.
Does this library require a physical cardboard to work?

According to the Readme.txt RajiwaliVR is a combination of Rajiwali and Google Cardboard Toolkit.

While Rajiwali is licensed under Apache 2.0, Vuforia is not a free to use License and thus my question is:
Is the Vuforia License reference in the License.txt file just a mistake (maybe oversight from porting from Rajiwali + Vuforia) or is it required to buy the Vuforia license if I want to use RajiwaliVR?

Hello folks. I'd like to know if is possible to detect the touch event using the Cardboard in RajawaliVR. I tried some snippets how to handle the TouchEvent but I have no success.

The events are not fired when I touched the screen when I override the onTouchEvent on RajawaliCardboardRenderer class.

@Override public void onTouchEvent(MotionEvent me) { //The MotionEvent "me" has all of the data you need to make animation based on touch if (me.getAction() == MotionEvent.ACTION_DOWN) { //Called once at the start of the touch System.out.println(me.getAction() + " -- " + me.getX() + ", " + me.getY()); } if (me.getAction() == MotionEvent.ACTION_MOVE) { //Called repeatedly as touch point moves System.out.println(me.getAction() + " -- " + me.getX() + ", " + me.getY()); } if (me.getAction() == MotionEvent.ACTION_UP) { //Called once at the end of the touch System.out.println(me.getAction() + " -- " + me.getX() + ", " + me.getY()); } try { Thread.sleep(15); //Small delay to keep touch events from overflowing and decreasing performance } catch (Exception e) { } }

Hi,

I tested the new RajawaliVR with Cardboard 0.6.0 on a Samsung Galaxy S4 and a Samsung Galaxy S5 and I'm getting an odd behaviour when shaking the phone, I've captured videos using both the previous RajawaliVR + Cardboard version and the new version:

https://youtu.be/YQMWDoeJD8w
https://youtu.be/wZLf1zjzXqU

I've included the information I thought relevant in the video description, but basically both phones have Android 5.* stock official Samsung firmwares.

I'm guessing that Carboard 0.6.0 must have changed something in terms of sensor readings perhaps, is this something that can be fixed on Rajawali's side or would it just be a matter of waiting for Cardboard to eventually fix itself up?

I'm available to help on fixing this as well, I'll be trying to do it but if anyone has any insights on what the problem might be and eventually on how to fix it, please let me know as well.

Thank you!

I would like to know if its possible to say Sweet 3D Home software, which is to create kitchen, house.. designs, which you can export the design to OBJ, the use this file to to display it in the Cardboard With a static position, not actually moving inside the virtual world. So you can see your kitchen space with CardBoard :)

It looks like Rajawali Framework can recognise OBJ format , can someone give me some hints if this is possible to do and how can that be achieved?

I render an plane with size(1,1) right on the screen like: mPlane.setZ(-4);
how to tell whether I am looking at the object?
how to get the camera matrix, model matrix, head matrix? Do I have to calculate the picth and yaw by my self?

I check the code and find private member
private Quaternion mCameraOrientation;
which returns value from -1 to 1 (360). it's this possible to use this to tell whether I am looking at the plane?

Thanks!

Hi,
I was not able to get this working - seems like the current Rajawali dev env has changed (Android Studio support?) so I cannot compile it, the required imports cannot be found...
Any ideas?

Thanks,
yakobom

I'm a bit inexperienced with Maven/Gradle. Do I run ./RajawaliVR/RajawaliVR/gradlew clean assembleRelease uploadArchives from anywhere special? Because running the task (or even ./RajawaliVR/RajawaliVR/gradlew tasks) gives the error code:

SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.

Thanks for your help.
