Droid OpenGL ES 2.0

---

I have a Nexus One and have successfully gotten OpenGL ES 2.0 up and running. I wanted to see if I could find someone with a rooted Droid who'd be willing to give me some info so I can find out if/how the same thing will work on it.

So far I have what I need. For those of you who have a Droid and want to start working with OpenGL ES 2.0 on it: You can do so through the Android NDK with a little hackery.

-You'll need to pull /system/lib/egl from your phone and put that in the ndk directory at: (ndklocation)/build/platforms/android-4/arch-arm/usr/lib/.
-Then download the opengl es 2.0 headers(you can find that at http://www.khronos.org/registry/gles/) and put gl2.h, gl2ext.2, and gl2platform.h in (ndklocation)/build/platforms/android-4/arch-arm/include/GLES2. Put khrplatform.h in "/"/"/"/"/"/KHR.
-Then setup your application to link to libGLESv2_POWERVR_SGX530_121.so by adding it to LOCAL_LDLIBS in your Android.mk file.
-Then just include gl2.h and you can start using 2.0!

If you want to build for the Nexus One, you'll have to get our libGLESv2_adreno200.so, which I'll make available here when I get hope today. Basically, you'll have to link against that instead.

If you want your app to work on both, you'll have to do some trickery with having two separate libraries so that if it's running on the Nexus One then it'll use it's library. I might work on making an open source library that'll load the right library so everyone can just load that before loading their own, but it'll be time consuming and I do have my own large project I'm working on, so I wouldn't count on that.

Well, us Nexus One folks shouldn't get all the fun, right? You'll now find a .zip containing an apk for an OpenGL ES 2.0 app which should(assuming what everyone here told me before was true) work on the Droid. It's pretty basic, just displays a triangle with some custom fragment shader graphics applied, but it does prove the ES 2.0 is running. Let me know if there's any problems(post it here, I'd rather not get 100000000 PMs/emails). Aside from that, enjoy!

Oh and I threw in the Nexus One ES 2.0 shared object file just in case anyone wants it.

The Droid's 2.1 Rom will go OTA soon with Open GL 2.0 support so roms will probably have this too.

The Nexus One doesn't really have ES2.0 support(despite having android 2.1; I had to hack the crap out of it to get it to work) so I doubt it would have support in the Droid(the SDK still doesn't have support). That aside, that really wasn't what I was asking. I want to know if these libraries already exist in the droid. As far as I can see, nobody has bothered looking yet and I suspect they're already in there.

I thought you meant it was native in nexus sorry.Droid has similar GPu to Iphone so Open Gl 2 should be capable on the droid.

No problem. Ya, I'm fairly sure it is opengl ES 2.0 capable. Just want to know where the libraries are located to see if it's the same as on the N1. On a side note, I know there are plenty of talented devs on the Droid side, so if anyone can find a way to get an app made with the ndk to link with the /system/lib/egl folder, that'd be awesome as well.

If you have root privileges on your Droid please run the following in a terminal emulator and post the results(or you can PM/email me if necessary, but this won't have any personal information in it):

su
cd /system/lib
ls
cd egl
ls

That should let me know what libraries the Droid has, so I can try to match them up with the ones on the Nexus One and see what we're working with. I'm hoping it'll have the identical structure to the N1, which would make development and testing of ES 2.0 apps much easier.

Damn beat me here LOL.

I'm on Motorola Milestone, Android 2.0.

/system/lib/egl includes:
egl.cfg
libEGL_POWERVR_SGX530_121.so
libGLESv1_CM_POWERVR_SGX530_121.so
libGLESv2_POWERVR_SGX530_121.so
libGLES_android.so

Alright, any chance you can post that libGLESv2_POWERVR_SGX530_121.so(or PM/email it to me if you want to do it that way)? We may need it in order to make 2.0 apps for the Droid.

Also, any chance I could recruit you for some eventual testing?

do you rally want to know what is in /system/lib? there are so many files ...

same here, in /system/lib/egl:

egl.cfg
libEGL_POWERVR_SGX530_121.so
libGLESv1_CM_POWERVR_SGX530_121.so
libGLESv2_POWERVR_SGX530_121.so
libGLES_android.so
