virocore's Issues

I am calculating X,Y,Z by using Latitude and Longitude

Hi, I am calculating [X, Y, Z]by using Latitude and Longitude. I want to place text node in that position now. But when I place the object in those positions, I am not able to view the text node.

Should I need to reset my current position using the same method used for objects? How to reset current position of the camera to specific XYZ position?

Link used to calculate XYZ by lat and long: https://github.com/mattholl/geo-to-cartesian/blob/master/index.js

Note: I convert link code into Java.

Fill node with texture with repeating

Hi there. I need to apply some bitmap texture to the node but do not stretch my bitmap to fill node's width and height. I want to place few such images to fill all node's surface with this texture. How can i achieve this?

Crash when running the new arcore demo

I write some test code based on the original demo, sometimes the app crashes when onRendererStart() get called, please help me figure out the problem.

Here is my code:

public void onRendererStart() {
        mScene = new ARScene();
        mScene.displayPointCloud(true);
        Node node = new Node();
        Surface surface = new Surface(1,1);
        Material material = new Material();
        material.setDiffuseColor(Color.parseColor("#BF000000"));
        surface.setMaterials(Arrays.asList(material));
        node.setPosition(new Vector(0, 0, -1));
        node.setGeometry(surface);
        mScene.getRootNode().addChildNode(node);
        mViroView.setScene(mScene);
    }

The logcat messages are as follows:

ViroViewAR rotation everytime we re-enter AR

What happens when the camera occasionally turns sideways and then goes back to the vertical?

Question: Creating surface between virtual objects

I'm new in 3d development so sorry if I'll tell something stupid :)

The question is: Can i create surface between four (or if its possible more than 4) virtual objects (by getting their vectors). For example I will place 4 objects on floor, using ViroViewARCore.performARHitTestWithRay() after that i will have 4 vectors of these objects. Then I want to fill area between these objects (in our case it is square) with some texture. I think that I need to create a surface and then add texture to the surface, but maybe there is another way.

Any comments will be helpful.
Thanks.

video record

Is there a way to record video without sound? I'm going to record video with my own audio file.

VideoTexture issue

I have played with your sample app for android ARCore and I have troubles with the VideoTexture.

I would like to play simple mp4 from url: https://media.giphy.com/media/WB0ZxnwTNOOBy/giphy.mp4

See code below:

final VideoTexture videoTexture = new VideoTexture(mViroView.getViroContext(), Uri.parse("https://media.giphy.com/media/WB0ZxnwTNOOBy/giphy.mp4"));
final Material material = new Material();
material.setDiffuseTexture(videoTexture);

final Surface surface = new Surface(10, 10);
surface.setMaterials(Arrays.asList(material));

videoTexture.play();

final Node node = new Node();
node.setPosition(position);
node.setGeometry(surface);

mScene.getRootNode().addChildNode(node);

but the app crashes after line fina VideoTexture videoTexture = ....

GIF support

Do you have any plans to support GIFs?

Is this possible to detect vertical object such as wall?

Hello,

Is this possible to detecting vertical plane such as walls and put an object on it. Currently using this SDK we detect horizontal surface but what about the vertical surface?

Is it possible to use only sceneKit (or somehow desrease lib size)?

I don't need the part with AR, I only need a scene API.
I ask this because compiled library size is 22MB if I understand everything right and this is just way too much.

For example, jpct-ae size only 3mb.

Weird rendering of the Text

I'm trying to render a 3D text ("Hello"), but getting this weird output when I run it:

Interestingly, the size of the letters match to the Hello text, but the pixels are all looking like 5s.

The code is:

        Text text = new Text(mViroView.getViroContext(), "Hello", 2, 1);
        text.setHorizontalAlignment(Text.HorizontalAlignment.CENTER);

        // Create a Node, position it, and attach the Text geometry to it
        Node textNode = new Node();
        textNode.setPosition(new Vector(0, 0, -1));
        textNode.setGeometry(text);

        Scene scene = new Scene();
        Node rootNode = scene.getRootNode();
        rootNode.addChildNode(textNode);

        mViroView.setScene(scene);

Any ideas on what might be causing this?

ViroSample-scene fails on Samsung Galaxy A5 (2016)

Hi guys!

The app crashes on Galaxy A5 2016 in scene demo, I know it doesn't support ARCore, but it looks like scene features must be supported.

How can I help you debug it? here is my logcat:

Provide Bounding Box For nodes

I couldn’t find boundingBox or boundingSphere for Viro3DObject, so can you recommend a way I could get the dimensions (width, height, depth) of my Viro3DObject node?

Use case: I have a bunch of 3D models, and a want them to fit inside a 0.2 x 0.2 x 0.2 box. So I basically want to calculate the scale amount I need to scale them to fit.

Need Help with Loading PBR Model and Materials

I am trying to render simple obj model in with PBR asset.zip

another assets https://poly.google.com/view/5vbJ5vildOq
PBR enabled:

 RendererConfiguration config = new RendererConfiguration();
        config.setShadowsEnabled(true);
        config.setBloomEnabled(true);
        config.setHDREnabled(true);
        config.setPBREnabled(true);

        mViroView = new ViroViewARCore(this, this, config);

When model is loaded :

   @Override
    public void onObject3DLoaded(Object3D object3D, Object3D.Type type) {
        Log.e("Stand", "onObject3DLoaded");
        final List<Material> materials = object3D.getMaterials();
        for (Material material : materials) {
            material.setMetalness(0.6f);
            material.setRoughness(0.1f);
            material.setLightingModel(Material.LightingModel.PHYSICALLY_BASED);
            material.setTransparencyMode(Material.TransparencyMode.RGB_ZERO);
        }
    }

Environment:

   Texture environment = Texture.loadRadianceHDRTexture(Helper.getUri(ASSET_PATH));
        mArScene.setLightingEnvironment(environment);
        mArScene.setBackgroundTexture(environment);

Result:

Something wrong with material? Any help will be appreciated!

Add Support for GLTF 3D Format

PBR dosen't work properly

I used PBR on viro 1.03
but I think it dosn't work properly on 1.04 even sample code at https://virocore.viromedia.com/v1.4.0/docs/physically-based-rendering

Am I wrong? or 1.04 has some bug?

Access to raw camera data in ARCore session?

Hi there, thanks for this project!

Is it possible to get access to the raw camera data during an ARCore session? I created an issue with the arcore team for the same functionality, and they suggest using a separate surface, and reading the data from there. They even provide an example TextureReader that could be used, as long as you have the textureId.

If ViroCore doesn't provide this functionality, does (or can it) provide a reference to the background texture, so that I can use the TextureReader above?

Add support for Autofocus once ARCore enables it

Virocore seems to miss autofocus on camera. Focus is fixed. Can I set autofocus just like on android camera app?

The color is very dark for the recording video.

The color is very dark for the recording video, however the color of the screen shot is fine.
Tested on Google pixel 2 with ViroViewARCore api.

How to load .mtl file of Object

Hello,

When I have to create 3D model, I have got .mtl file related to the 3D model. So how to load a .mtl file in virocore ?

Add overlays for video

Hello Dear Viro support team,

Lets imagine I left an object on scene, and also above the scene I'm showing some frame, for example photo frame as ImageView above Surface view.
Now I want capture video, is there any way add overlay to the video?
Should it be added as object on scene or there is another way?

Many thanks, kind regards, Ivan

Make "Bitmap" screenshot without saving to file

Hello Dear Viro team,
is there any way to make screenshot without save to file chain?
I just found only ViroMediaRecorder and recorder.takeScreenShotAsync method.
I need to have a bitmap. Is there any another public API or plans to provide it?

object persistency in AR

I want to create an application that store the position,rotation and scale of multiple object and when i close application and reopen than all the stored object must be at there respective position.

I am able to place object with the stored position but issue is that i can't place than at correct position as earlier.
the object are overlapping with each other.

Do you have any solution around that.I am looking for android app side.

Nested portalscene content is shown outside of portalscene?

I have a portal (portal 1) (a rectangle with a transparent cover in the middle, which shows the portalscene) at -0.5f in front of me.

I have a portal (portal 2) (same rectangle shape) inside the portalscene of the first portal, located at +0.5f behind me.

If I look around in the ''real world'' I only see portal 1. If I look around inside portal 1 I can find portal 2.

However, if I position myself so that portal 2 is behind portal 1 while I'm in the portal 1 portalscene, I can see portal2 inside the real world. (It does not get cropped out of the view into the ''real world'')

I will add images and code later to expand if necessary. It may be due to user error, but as the documentation is kind of lacking for Portals I've been trying to figure it out on my own. :p

ProductARActivity is not needed

https://github.com/viromedia/virocore/tree/master/ARRetail/app/src/main/java/com/example/virosample

Hi.
I would like to propose two modifications.

• Delete ProductARActivity
• Rename ProductARActivityComplete to ProductARActivity.

First, ProductARActivity does the same thing as ProductARActivityComplete (INTENT_PRODUCT_KEY also exists in ProductARActivityComplete).
Next, ProductARActivity's name is easily and simply than ProductARActivityComplete.

I fixed it, so please give me permission if necessary.

ViroCore is so cool. Thanks.

Camera resolution

Now what resolution do we support? I think the resolution is a little bit low right now?

Set camera lookat to a fixed point

I am trying to set lookat of my camera to a fixed point of my model and then rotating my camera to view it from different angles. But the lookat doesn’t seems to be fixed and my model goes out of window when I move my camera. I am using below code to achieve this:

final Scene scene = new Scene();
    obj = new Object3D();
    Vector position = new Vector(0, -1, 0);
    obj.setPosition(position);

    obj.loadModel(Uri.parse("file:///android_asset/truck.obj"), Object3D.Type.OBJ, new AsyncObject3DListener() {
        public void onObject3DFailed(String error) {
            Log.w(TAG, "Failed to load the model");
        }

        public void onObject3DLoaded(Object3D object, Object3D.Type type) {
            Log.i(TAG, "Successfully loaded the model!");
            object.setScale(new Vector(0.2f, 0.2f, 0.2f));
        }
    });

    AmbientLight ambient = new AmbientLight(Color.WHITE, 1000.0f);
    scene.getRootNode().addLight(ambient);

    cameraNode = new Node();

    camera = new Camera();
    camera.setRotationType(Camera.RotationType.ORBIT);
    camera.setPosition(new Vector(0, 50, 3));
    cameraNode.setRotation(new Vector((float) 0, -Math.PI / 2.0f, 0));
    camera.setOrbitFocalPoint(new Vector(0, -1, 0));
    cameraNode.setCamera(camera);

    scene.getRootNode().addChildNode(cameraNode);
    scene.getRootNode().addChildNode(obj);
    mViroView.setPointOfView(cameraNode);

    mViroView.setScene(scene);

Now when I move my camera to a position like camera.setPosition(new Vector(0, 50, 40), my object moves somewhere out of the screen.

Please let me know if I am missing something.

Not proper description for portal scene.

There is not a single example related to the portal scene in virocore sdk. Can you explain how to use portal scene using this SDK ?

I have read a document of virocore sdk but there is no proper description found for a portal scene in android.

Referred URL: https://virocore.viromedia.com/docs/augmented-reality-ar

Change min sdk from 21 or remove constraint

Currently right now developers have to change their min sdk to 21 to use Viro. While it makes sense, this seems really short sighted as it hardly takes into account an app that is not primarily AR or already existing with users that are not on 21.
Using tools:overrideLibrary="com.viro.renderer" allows for compilation but of course, still breaks when trying to use. It would seem that ideally users should be able to integrate or start with Viro fairly easily, especially to avoid having to split their project to support two apks on the play store. The current Android SDK just crashes when code is referring to features that are not supported. It allows for the developer to be able to do things like check the sdk and choose whether or not to allow the user to access that feature.

Perhaps it is something to consider.

updated time

arcore updated, virocore will update soon, is it right ?

Question about rotate

How can i rotate object? I was thinking it will works like dragging, just add DragListener, but i was wrong. Thanks.

Change materials of loaded .obj file at runtime

Github Issue to track a developer feature request.

"I am trying to change parts of a loaded .obj file at runtime. The textures are loaded first via an .mtl file. Whenever I try to get a reference to the materials to change them at runtime the materials are null.

What I would like to achieve:I would like to only change one texture of the loaded 3dObject, not the diffuseColor or the diffuseTexture. How can this be achieved?"

Camera button doesn't work

Hi.

CameraButton doesn't work in ARRetail.
Error message in Logcat is below.

E/Viro: onTaskFailed NO_PERMISSIONS

Camera button does work when I set permission in settings.
Maybe, I think that ARRatail is caused by not setting Runtime permission about Storage.

Thanks.

Enviroment

- Pixel XL
- Android 8.1(API:27)

flash

Do virocore support camera flash?

Difference warnings look very suspiciously....

After that I have loaded vrx model as usual :

    Object3D model = new Object3D();
        model.setPosition(new Vector(0, 0, -2));
        model.setTag("bb8 model");
        model.loadModel(getUri("bb8_v.vrx"), Object3D.Type.FBX, new AsyncObject3DListener() {
            @Override
            public void onObject3DLoaded(Object3D object3D, Object3D.Type type) {
                Log.e(LOG_TAG, "loaded success tag " + object3D.getTag());
                Log.e(LOG_TAG, "geometry " + object3D.getGeometry());
                
                mArScene.getRootNode().addChildNode(object3D);
            }

            @Override
            public void onObject3DFailed(String s) {
                Log.e(LOG_TAG, s);
            }
        });

I got next log:

I have received message "load success" but 3d Objects geometry was always null, and of course nothing appears on the screen (AmbientLight is added).
After that I have tried to do the same with 5 difference FBX models from difference sources - I had almost the same result...
Link to described above asset https://free3d.com/3d-model/bb8-35865.html

UPDATED
The best result I could get, was the white 3d model (without texture), and geometry was null as well.

Asset for Audi R8 https://free3d.com/3d-model/audi-r8-14024.html
converting log for Audi is warningless, so iI think the issue with BB8 is in fbx model itself.
The question with white texture in vrx mode is open .

Sample not running

Hey, thanks for all your efforts in creating this sample for ARRetail, I'm facing a problem though that I can't run the sample project, whenever I run it a popup appears saying that:

This feature requires the latest version of ARCore with two buttons continue and cancel when I click continue another pop-up appears and says item not found with a retry button. Anybody knows how I can solve this issue?

Thanks.

Hit test bug in v1.3

After migrating to version v1.3 I noticed that ViroViewARCore.performARHitTestWithRay() stopped working as before. Now vector position from ARHitTestResult is not camera center position. Reproduced in sample app ViroARObjectPlacementActivity.

v1.2

v1.3

when happend SURFACE_NOT_FOUND

Whether virocore can identify the current scene without light.

It is possible to combine the library with location services ?

Hello. I am wondering is there any options for combining the library and static gps coordinates. I need to spawn objects in real world coordinates. I found many examples on Unity. but for android I can't find some useful information. Virocore has good API but I can't find any options too

Framework doesn't render simple texture described in mtl

Hi guys.
I went through this #2 and I didn't manage to render simple texture described in mtl ...

what I do:

 Object3D object3D = new Object3D();
        object3D.setPosition(new Vector(0, 0, -2));
        object3D.loadModel(getUri("model.obj"), Object3D.Type.OBJ, new AsyncObject3DListener() {
            @Override
            public void onObject3DLoaded(Object3D object3D, Object3D.Type type) {
                Log.e(LOG_TAG, "loaded success");
                mArScene.getRootNode().addChildNode(object3D);
            }

            @Override
            public void onObject3DFailed(String s) {
                Log.e(LOG_TAG, s);
            }
        });

what I got:
