How to enable ES 3.0 in ANGLE

[Rishi Ranjan]

Hi,

    I have successfully compiled ANGLE and am able to play with samples but when I query the GL_VERSION, it returns 'OpenGL ES 2.0 (ANGLE 2.1.b'')'. I understand that 3.0 support is not complete but most of the features are working so I want to force the ANGLE in ES 3.0 mode. I will make sure not to use ETC2. 

Is there a simple config parameter which can force it to ES 3.0? I did check the code and client version is being checked against 2.0 and 3.0 so there should be a way to do this. 

Also I am trying to use ANGLE to test Instanced rendering in Android Emulator. In code, it's marked as not supported. Can I reuse GL_ANGLE_instanced_arrays to implement OpenGL ES 3.0 instanced rendering. In code I see that DrawElementsInstanced has a UNIMPLEMENTED();

Thanks,
Rishi

Hi Rishi,

Two questions: 

  * How are you obtaining your GLES context? A ES 3.0 context should be requestable via eglCreateContext by using an EGL_CONTEXT_CLIENT_VERSION of 3 in the attrib list.

  * Are you running ANGLE on a D3D10+ capable system? ES 3.0 support is not available in ANGLE on our D3D9 backend.

Hi Shannon,

                 I was trying to change simple_instancing example first to see if OpenGL ES support is returned in GL_STRING and get the Instancing working with this example before trying this with Android emulator. I will change the code to request ES 3.0 . 

using eglCreateContext. 

My PC has DirectX 11. 

Can you please provide your input on adding Instancing support in ANGLE. I am copying the question from my last mail:

Worth noting: we recently (just today) had an external contributor add DrawElementsInstanced support in this CL:

(That CL also includes DrawArraysInstanced, I think.)

The one remaining bit of instancing support for ES 3.0 still missing from ANGLE, after that CL, is VertexID/InstanceID built-ins in the shading language, so be aware that if your application uses those, they are not yet supported

Thanks for pointing me to this CL. I will merge these changes and use it for now. My application is not using VertexID/InstanceID in vertex shader so this should be good enough for me. 

Thanks,

Rishi
