Enabling OpenGL ES 2.0

[John Villar]

Hi all, first time in this group. I have recently bought a chinese tablet which has some pretty decent horsepower (PowerVR SGX 530, dual core CPU, 4 GB Internal memory plus 512 MB RAM, and 4-6 hours battery with game use) and it did come with Froyo. However, whenever i try to run an application that uses OpenGL ES 2 it fails telling me that my device doesn't support it.

I checked the binaries and they all are there on /system/lib and the  OGLES 1 extensions indicate the existance of some OGLES 2 characteristics (like ETC1_RGB8 compression and VBOs) but i can't seem to figure out how to enable it on the low level to make it work.

I would be very grateful if anyone can point me in the right direction to enable it system-wide.

Nice porting everyone :)

Hi John,

PowerVR SGX 530 does support OpenGL ES-2.0

Some of the Android applications use Android APIs to query the OpenGL ES version(s) supported by the target platform. As far as I know, this information is mainly present as a system property in /system/build.prop file. If this is the case with your application then add this property "ro.opengles.version=131072" in /system/build.prop file and see if that application can detect OpenGL ES 2.0 profile.

Hope that helps. Let us know how it goes.

Thanks for your answer Amit, will try that tonight and will report back.

The SGX 530 does support OGL ES 2.0 (it is the GPU on the Motorola Droid/Milestone and a less powerful variation of the iPhone 3GS GPU) check these:

• http://en.wikipedia.org/wiki/PowerVR
  
• http://www.imgtec.com/powervr/sgx_series5.asp
  

That's why i was surprised that my tablet didn't support it although it has the power to do so.

Sorry about my last post, misread Amit's comment and i tought he was saying that the SGX doesn't support OGL ES 2.0

Sorry, my bad :(

Worked like a charm!! Now i have my proper OGL ES 2.0 development platform :) thank you Amit.
