Hi al!! I’am using the last PowerVR SDK 4.1, I need of support some extensions:

GL\_EXT\_draw\_instanced, GL\_EXT\_instanced\_arrays, GL\_OES\_vertex\_array\_object

PowerVR SGX 543/544 supports these extensions:

[https://developer.apple.com/library/ios/documentation/DeviceInformation/Reference/iOSDeviceCompatibility/OpenGLESPlatforms/OpenGLESPlatforms.html](https://developer.apple.com/library/ios/documentation/DeviceInformation/Reference/iOSDeviceCompatibility/OpenGLESPlatforms/OpenGLESPlatforms.html)

Can you add it for OpenGL ES 2.0 Emulator ?

Also, i found the support of extensions GL\_IMG\_uniform\_buffer\_object and GL\_IMG\_vertex\_array\_object  
where is documenation for it?

Thanks!

Hi Andrey,  
GL\_IMG\_vertex\_array\_object  
Not exposed, as was superceded by GL\_OES\_vertex\_array\_object.  
You can find it here:  
[https://www.khronos.org/registry/gles/extensions/OES/OES\_vertex\_array\_object.txt](https://www.khronos.org/registry/gles/extensions/OES/OES_vertex_array_object.txt)

GL\_IMG\_uniform\_buffer\_object  
No extension spec, don’t want to continue supporting it.

We will add those extensions in PVRVFrame in future release.

Thanks,  
Kevin

Thanks! Now, The OpenGL ES emulator supports these extensions!
