This issue appears to be fixed in version 10.1

While this works fine in version 9, in version 10.0 the Antialiasing setting has no visible effect any more

enter image description here

I'm here on Ubuntu 12.04 64-bit with Gnome 3.4.2 and an NVidia GeForce GTX 590 with NVidia driver.

Do others experience this and is there any known solution to the problem?

  • There is a visible change for me when I move the slider. Bodhi 2.4.0 x64, Radeon HD 3650. – mfvonh Jul 20 '14 at 01:24
  • Given the flashing problem you also reported: which graphics card driver version are you using, and is it the latest? – Oleksandr R. Jul 20 '14 at 02:17
  • @OleksandrR. Currently updating to the latest. I wasn't thinking of this because in all other Mathematica versions and in the beta it worked. – halirutan Jul 20 '14 at 02:25
  • Perhaps they linked against a different library version in the final build that introduced this problem. But this is sheer guesswork. If the problem persists despite the update I suppose you'll have to report it as a bug. – Oleksandr R. Jul 20 '14 at 02:28
  • @OleksandrR. No, nothing changed with the latest driver. I have reported this to wolfram, but I always dislike sending them screencasts, images etc. Therefore, I regularly post the issue here and link in my bugreport to this site. Btw, do I have to mention that all the issues were introduced in the final release version of 10? – halirutan Jul 20 '14 at 08:22
  • I have the same behavior (i.e. no visible change) under also under Linux with a NVidia card. – sebhofer Jul 21 '14 at 09:32
  • @sebhofer Would you consider upvoting the question then to indicate your interest in the issue? – halirutan Jul 21 '14 at 10:40
  • Same issue on my end (nothing changes). I'm using internal Intel graphics (HD4000). – gst Aug 29 '14 at 22:24
  • Same here with Xubuntu 15.04 and NVidia GeForce 7600 GS. – shrx May 16 '15 at 08:15
  • @shrx In 10.1 this is fixed for me. – halirutan May 16 '15 at 08:23
  • @halirutan thanks, unfortunately we don't have a licence for 1.0.1 at work. – shrx May 16 '15 at 10:33

I had to modify the /usr/local/bin/mathematica script to fix 3D antialiasing. It seems that the GLTest script fails and as a consequence Mathematica disables advanced 3D rendering. The fix is to replace the line

GLTestResult=`${GLTest} 1 1 1 2 ${userDisplay}  2> /dev/null | grep "GLTest_OK"`

with

GLTestResult="GLTest_OK"

and now antialiasing works. Seems like a bug or improper test procedure to me. Tested with Mathematica 10.3.0 on Xubuntu 15.10 with Nvidia GeForce GT 730. Note that I did not have to export MATHEMATICA_GL_FBO=1 to enable antialiasing.

  • I was wondering, do you have libglu1-mesa installed? – ilian Dec 03 '15 at 14:22
  • @ilian Yes: libglu1-mesa: Installed: 9.0.0-2 – shrx Dec 03 '15 at 14:32
  • @shrx This is an awesome answer, because on my new machine, I swiched to XUbuntu and I have the same problem. Until now, I had no time to investigate further. It seems you did all the work for me :-) +1 of course – halirutan Dec 03 '15 at 21:51
  • @ilian The missing dependency on XUbuntu 14.04 is libMesaGL.so.1 for the gltest program. The library cannot be found although libglu1-mesa is installed. A quick google search gave me no real information why this library isn't there or whether it should be there. Does this help? – halirutan Dec 04 '15 at 02:49
  • @shrx Would you mind to repost your answer here. This is clearly a different bug and we should make an extra question for it. Please don't delete this answer until ilian has seen that we moved the topic. – halirutan Dec 04 '15 at 03:16
  • @halirutan libMesaGL.so.1 isn't missing, it's included with Mathematica and is on LD_LIBRARY_PATH at runtime. The problem is not that gltest is missing a dependency, but that it runs and returns GLTest_Fail for some reason. This is being looked into. – ilian Dec 04 '15 at 04:03
  • @ilian Right. I saw now that this lib is given in the install-path of Mathematica and that gltest just fails. I have updated the new question here. It would be nice if you report back and in case you need further information from my machine, just drop me a mail: Uncompress["1:eJxTTMoPChZhYGAoSCwpykzOdshIzMksKi1JzNNLSQUAgX0JmQ=="] – halirutan Dec 04 '15 at 05:04

This appears fixed as of Mathematica 10.1.0, at least on my 32 bit Linux with NVidia Geforce GTX 750 Ti and binary driver 340.46, where the bug does reproduce with Mathematica 10.0.0.
