Antialias Support in Irrlicht opengles2.0 ?

[vivekSivamRP]

Does irrlicht opengles2.0 supports antialiasing ? While creating the device (creatdevice(Param)) i have tested with the param.AntiAlias values, did't find any change in the aliasing issue. Can anyone suggest the right way to achieve this in irrlicht opengles 2.0 ?

I never tested this feature on ES2 (on mobiles it's not a popular feature), but I'll try to find and fix this issue.

Thanks Nadro. Any clues on fixing this issue ?

[Nadro]

On which platform did you test it? I think that it may be problem with EGL configuration, but I didn't check that yet.

[vivekSivamRP]

Yes For IOS platform.

No!! Don't give Nadro more things to do, we wont get cubemaps until 2019.

I checked EGL config and it seems fine (on Android it should works fine). On iOS AA is missing, however you can check how to modify Irrlicht to enable multisampling:
https://developer.apple.com/library/ios ... -CH103-SW4
You should apply these changes to COGLES2Driver constructor. I'll apply it to a repo, when I'll find some free time.

Thanks nadro, I followed the steps which is given in the link exactly, but did't find any change in rendering quality. Even tried various sampling values but no use, i might've missed something. Will produce the code after fixing the issue.

You can try to add a following line:

Code: Select all

glEnable(GL_MULTISAMPLE);

[vivekSivamRP]

GL_MULTISAMPLE is not enabled for opengles2.0, so it is throwing error. Any other way ?

[Nadro]

Which device do you use for a tests?

[vivekSivamRP]

iPad4 (Retina) and simulators for iPhone6+,iPhone6.

[Nadro]

On iPad all should works, on simulator probably too. Currently I'm busy by other task, so I'll check that in the future. Anyway on Retina devices you don't need AA in most cases. High PPI solve this issue.

Ok. I will try it once again and report the result.
