3D textures does not render on GW620

[GoogleCodeExporter]

There are problems with textures in 3D games with my Etna. You can try it 
yourself with those apps:
Mistique episode 1 (free)
Neocore benchmark (free)

Just run the game/benchmark and see - in Mistique there are colored lines 
instead of textures, in Neocore only Halos are rendered. Interesting is that 
other 3D stuff (Gallery, Sygic Aura, Tank Hero, ..) works properly.

I heard about that Android 3.0 is able to render real 3D.

Thats not the case. For example, Neocore benchmark WORKS (just a little bit 
slow) on openetna froyo firmware, so this is a real bug in OpenEVE firmware

@schemaker // Nexus also known that necore bench did not work.
so it is not OpenEVE or CM7 bug.

this is compatibility issue i think.
and currently there is no known way to workaround this issue.

and.. Aututu bench or Quardrant standard are well known 3D benchmark app.
these are work perfectly with CM7.

I kinda feel you dont get it. Ive tried Neocore on Froyo release of OpenEtna 
and it worked pretty nice (with 10~15FPS) with no graphic issues. So there 
actually is some problem in OpenEVE GPU driver as Adreno 130 IS featured enough 
to run that benchmark (it's OpenGL ES 1.1). Im not sure about Mistique tho, 
that may be (or may be not) working on our phones, but since it just does 
texture rendering artifacts, im pretty sure it should work as well.

Yeah, i actually misunderstood you (sorry then, im not native English speaker). 
I guess youre right and it may be compatibility issue. Did some research and i 
noticed people having issues with Mistique when Cyanogenmod or Gingerbread is 
used. I guess i just filled invalid bug.

I have found something. It works but no source code found.

we just need only two libs.
 * libEGL.so
 * libGLESv1_CM.so

these are just wrapper libs of to support hardware openGL.

you can copy it manually by following

 adb push libEGL.so /system/lib/
 adb push libGLESv1_CM.so /system/lib/
----
without sound, about ~26.5 fps obtained.

----
it will not be included into OpenEVE GB without source code.

libEGL.so / libGLESv1_CM.so of OpenEtna also works fine.

its more faster than prev libs.
without sound, about ~29 fps.

3d gallery runs a little slow if you open and change of direction that locks 
the screen and exits. Place these files and now the gallery 3d screen changes 
without binding even though it shows a little at a time to move on the screen.

Sorry for my English. I am using a translator  :P

Using the files in the package egl.zip
Because the package etna-egl.zip fails and locks the 3d gallery

OK. I have found solution to work texture correctly with Neocore.

Yup, neocore works fine now (21.9 FPS out here), but Mistique is still messed 
up. Anyways .. good job and really great bugfixing speed - keep a good job.

Neocore is regarded as reference app made by Qualcomm.

and this workaround hack does not guarantee all other openGL apps work 
correctly.

but we can say that
"reference app like as Qualcomm's Neocore works but your app does not work.
please fix it"
