Linux/TDA2PXEVM: DRA76p with Linux -> TDAP2X AVB

Hi Ramesh,

Can you elaborate on the aliasing issues you are seeing. Do you see any artifacts on the output, do you have any pictures/snapshots of the artifacts.

What is the TI baseline release you are using? Are there any modifications on top of it?

On a general note, DRA76P supports OpenGL ES2.0 and you would have to use GLES 2.0 API to configure any anti-aliasing you would need.

Thanks,

Gowtham

The OPenGL functions for anti-aliasing have been added and tested with Ubuntu PC i.e. X11, works fine but on Jacinto the issue pops up.

Checking for snapshots with team...

Do you know what specific API calls are being used. Note that Jacinto
platforms support OpenGL ES2.0 API, a desktop PC can support desktop OpenGL
API as well. If you are looking to see if any specific extension supported do
let us know, we will confirm if that is supported.

Thanks,

PFA code above for enabling anti-aliasing.

Did you check the same yet?

Code is as follows -> 

QSurfaceFormat format;

format.setSamples(8);

format.setDepthBufferSize(24);

QSurfaceFormat::setDefaultFormat(format);

Hi Gowtham,

Thanks for the response.

From the TDA2Px spriuf0b , I see

• Anti-aliasing:
– 4× multisampling
– Programmable sample positions

Could you please indicate which registers in the 3D Graphics accelerator block can be used to set the following

– 4× multisampling
– Programmable sample positions

Hi Ramesh,

You need to setup anti-aliasing through standard OpenGL ES2.0 calls, not through register setting. All graphics state need to be programmed through OpenGL ES2.0 API.

Thanks,
