glError 1282

[pranavkotecha88]

Hi guys, I am trying the arcore in one of my apps, and I get stuck at this point, where it gives me a glError 1282.

E/HelloArActivity: Exception on the OpenGL thread java.lang.RuntimeException: Setting up to draw planes: glError 1282 at ar.rendering.ShaderUtil.checkGLError(ShaderUtil.java:71) at ar.rendering.PlaneRenderer.drawPlanes(PlaneRenderer.java:359) at ar.HelloArActivity.onDrawFrame(HelloArActivity.java:291) at android.opengl.GLSurfaceView$GLThread.guardedRun(GLSurfaceView.java:1562) at android.opengl.GLSurfaceView$GLThread.run(GLSurfaceView.java:1262)

Any one faced this issue? I am using s8, and have installed the arcore-preview apk. Strangely the app works independently (HelloAr Java), but when I integrated the app in my custom app, it gives me this exception.

Hi, I am getting this exception while surface detection in ShareUtility Class throw new RuntimeException(label + ": glError " + GLES20.GL_NO_ERROR);

@imknown that's a different error. It's coming from ObjectRenderer.java:128 while the previous ones were from PlaneRenderer.java:359

@741g @tpsiaki Any clue what's going on in @imknown's post?

[741g]

We'd have to know the user's GPU model here. Seems like a GPU driver issue. Please provide emulator -verbose command line output and logcat from device startup so we see the configuration.

[imknown]

@inio @741g @tpsiaki Thank you all~

Here's my avd boot cmd:

#!/bin/bash
emulator -avd API-27 -http-proxy http://127.0.0.1:1081 -debug-proxy -dns-server 8.8.8.8 -use-system-libs -verbose

Logs below, and thank you all~

What hardware GPU do you have? It looks like you're using Mesa, which is definitely behind Swiftshader in terms of ES 3.0 conformance and behind many modern hardware GPU drivers as well:

03-01 08:40:50.999 1399-1399/? I/SurfaceFlinger: vendor : Google (X.Org) 03-01 08:40:50.999 1399-1399/? I/SurfaceFlinger: renderer : Android Emulator OpenGL ES Translator (AMD OLAND (DRM 2.50.0 / 4.13.0-36-generic, LLVM 5.0.0)) 03-01 08:40:50.999 1399-1399/? I/SurfaceFlinger: version : OpenGL ES 3.1 (4.5 (Core Profile) Mesa 17.2.8)

Can you tell us more about your hardware setup? glxinfo on command line can help.

Also, try to launch the emulator with -gpu swiftshader_indirect; that will use the Swiftshader software renderer which is more conformant with ES 3.0.

edit: another way to get to that setting is to go to the extended settings panel > Advanced > OpenGL ES renderer (requires restart)

@inio Also, can I get more background on

02-26 14:31:33.624 6113-6129/com.google.ar.core.examples.java.helloar E/ObjectRenderer: Texture loading: glError 1282

and

java.lang.RuntimeException: Setting up to draw planes: glError 1282

in terms of the sequence of GL calls? It's possible that we could trace down the exact driver bug that is affecting Mesa and Samsung, and de-risk the implementation so that it can work even with those drivers.

@741g

The Setting up to draw planes error shows up on select Samsung S7 devices (we haven't been able to repro).

E/ObjectRenderer: Texture loading is here.

@inio @741g Iam using: VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Oland XT [Radeon HD 8670 / R7 250/350] (rev 83).

No available drivers to be installed in the ubuntu Additional Drivers.

Totally i found that hello_arcore_c works fine with ndk-bundle.

However... The XFCE Window cannot get the focus to use alt to move around in the VirtualScene. Gnome is ok. Perhaps this is caused by the Press Alt to move camera. dialog?

[741g]

@imknown I see, that seems to be an older AMD GPU that can have issues with OpenGL ES conformance.

For the hello_arcore_c, do you mean that hello_arcore_c works while the Java version throws the 1282 error? That is a very important clue!

The XFCE Window problem is unexpected, hmm. Could explicitly clicking back in the emulator window to regain focus help things?

[imknown]

Thank you~

@741g Yes, the Demo Java raises the gl error 1282, and the Demo C does not throw any exceptions.

Explicitly clicking the window multiply times works for AVD normal screen and it regains before i use VitrualScene.

But the new VitrualScene in System Camera App and ARCore Demo lost focus immediately after the main avd window focus regained. I find that the Press Alt to move camera. dialog blinks when i quickly continuously press alt.

Already tried: https://stackoverflow.com/a/42720450/2782426

I tried the arcore on Windows moments ago. All things work like a charm, hahah~

@imknown For the 1282 error, you can work around it by modifying HelloAR Java's ObjectRenderer.createOnGlThread, moving the shader loading code to the top of the function:

    final int vertexShader =
        ShaderUtil.loadGLShader(TAG, context, GLES20.GL_VERTEX_SHADER, R.raw.object_vertex);
    final int fragmentShader =
        ShaderUtil.loadGLShader(TAG, context, GLES20.GL_FRAGMENT_SHADER, R.raw.object_fragment);

    program = GLES20.glCreateProgram();
    GLES20.glAttachShader(program, vertexShader);
    GLES20.glAttachShader(program, fragmentShader);
    GLES20.glLinkProgram(program);
    GLES20.glUseProgram(program);

    ShaderUtil.checkGLError(TAG, "Program creation");

The error occurs when calling glGenerateMipmap before glUseProgram. We're still investigating the root cause.

For the VirtualScene focus bug, I'm investigating and will follow up when I have more information.

@jwmcglynn Thanks, and it works~ Now the Demo Java does not crash nay more.

@imknown Here's a private build of the emulator on linux that should resolve your VirtualScene focus bug: https://drive.google.com/file/d/1tLRZbEimaC9V9TJpP5EhQlzk-xLkRtwN/view?usp=sharing

[imknown]

@jwmcglynn WOW, Thanks! The VitualScene focus bug is gone. Now I can move and look around when pressing the Alt. :laughing: :laughing: :laughing:

P.S.: Other normal window focus bug is still there. So I cannot use the Ctrl and mouse to simulate the double fingers actions. The mouse wheel works fine. :laughing: :laughing: :laughing:
