OpenGL ES hardware database and CapsViewer

[Sascha Willems]

Some of you might know (and already use) my online OpenGL hardware database that I've set up sometime ago and which is approaching 500 different OpenGL implementations.

And as my first ever mobile project (or "app" as they're called today) I released an OpenGL ES hardware database and caps viewer to the public. This is the mobile equivalent to the desktop OpenGL hardware database and is planned as a tool for the mobile OpenGL ES programmer that wants to check out the OpenGL ES hardware capabilities of different mobile Devices.

The project itself was NOT made with Delphi (sorry guys, but I wouldn't touch FireMonkey from 500 feet afar with a stick ), but with google's excellent and free developement tools. Though the database may be of use for some Delphi (or at least Free Pascal) OpenGL ES developers out there, at least if there's some way of getting to the OpenGL ES context usually hidden by FireMonkey.

The database is filled with the OpenGL ES CapsViewer (you can grab it on the playstore), and is currently available for android (dunno if iOS makes sense due to the limited variety in hardware configurations).

The tool will work with Android 3.0 and up (though if there's demand I may add in older versions too) and supports all OpenGL ES versions available on Android (1.0~3.0)

Features of the OpenGL ES Capsviewer :
Information for the OpenGL ES implementation of the device :
- Versions
- Extensions
- Compressed formats
- Shader and program binary formats
- OpenGL ES 2.0 and 3.0 caps
- EGL implementation

It also gathers device information (no personal data!) that may be of use for developers :
- Operating system, screen size and CPU info
- Hardware sensors (including range and resolution)
- Android features

Note that this is the very first public version, and also my very first mobile application, so I guess it won't work on all devices. If it crashes for you, i'd be kind if you could submit the crash report to google and tell me about it so I can fix it.

The database itself is very similar to the OpenGL one, allowing you to check up on single devices, compare up to 8 devices, check out which device supports what extension, hardware feature or compressed texture format and so on.

Please note that I'm still working on the hardware database, so new features will be added over the coming days and weeks.

So if you've got an android device feel free to download the OpenGL ES capsviewer and submit your reports to the development community

Awesome. Tried it on my Nexus S (crashes at start, made a report), and my Xperia S (works).

Thanks a lot, especially for the crash report on the Nexus S. It looks like a problem with the config chooser for the render context :

java.lang.RuntimeException: createContext failed: EGL_SUCCESS
at android.opengl.GLSurfaceView$EglHelper.throwEglException(GLSurfaceView.java:1195)
at android.opengl.GLSurfaceView$EglHelper.throwEglException(GLSurfaceView.java:1186)
at android.opengl.GLSurfaceView$EglHelper.start(GLSurfaceView.java:1036)
at android.opengl.GLSurfaceView$GLThread.guardedRun(GLSurfaceView.java:1403)
at android.opengl.GLSurfaceView$GLThread.run(GLSurfaceView.java:1242)

Pretty funny first line. Returning success, but failing. I'll have a look into this and will release an update as soon as I found the cause for the crash.

Your new version shows information properly on the Nexus S now. Meant to post about that, but seems you got it fixed without me needing to tell you One thing that is incorrect, is the CPU frequency, which is shown as 1400 MHz (maximum for the CPU that the kernel can allow, since it is cyanogenmod). The actual frequency is 1000 MHz. Not a big deal, but thought you should know.

It seemed that the code for selecting a context with the highest possible OpenGL ES version wasn't working on several devices, so I changed it and well, it seems to work

And thanks for resubmitting the Nexus S with the correct OpenGL ES information version. As with the CPU Frequency, it's from the device information structure of android, so I don't know if I could easily detect wether the frequency is overclocked or not.

Nice project! Works great on my Galaxy SIII mini. Didnt even know this device supported OGL ES2
