Shader link failure when running JME Tests

Troubleshooting General Help
1

Hi,

hopefully this is not too stupid, I have just started to use JME…

Anyway, I am using svn with Eclipse and checked out yesterday (revision 7941 for “engine”).

Build runs just fine.

But when I try to run e.g. “TestHoverTank.java” (revision 6955) I get following output:

I already checked my graphics card and it supports OpenGL 2.1 (ATI Radeon XPress 1200).
I tried many other of the JME examples and they do not work either.
Any hints?
Any additional info that I would need to provide?
Thanks in advance,
Hans

Obviously your system is fubard, what can we do about it? Insall the latest drivers, if that fails go to the guys where you bought it and slap it around their head.

Wow, is there really nobody able to give me hint what could be wrong in my system?



Of course I checked that I have the most recent driver. And of course I already re-installed the driver after having the old one removed and even used driver sweeper just to make sure.

Still the same problem.



Also I checked with OpenGL Extension Viewer. All info about my graphics is dispayed correctly, but when I try the rendering I get following error:







Unfortunately it is in German :smiley: but it says something about access to some alternative memory location which normally only happens if the planned memory is damaged.

So of course I already checked my memory (memtest86+) which revealed no problems and I would not know that it would be possible to check the graphic card’s memory itself.



After that I also ran FurMark test and that worked without any error messages! The score is “71” which is very low I believe, but I do not know whether that is already a sign that something is broken.



GPU-Z also revealed nothing unusual.



PLEASE, I am starting to get desperate. I would really like to start using jME but I can’t :cry: :cry:

After some further investigation I understand that shader only starts shading once a light source is added. So I tried to remove the light source from one example (I used the HelloAsset from the introductionary tutorials) and the code works (except of course you do not see the ninja since there is no light for it…).

So it seems my shading does not work at all.

:?:?:?

5

So now I installed the jME SDK and I get this error message when I start the IDE:



What is wrong here?

:cry:



Here the first lines of the output window of the jMP:

Thanks for your answer, normen!



Well, my system can not really be called fubar. Everything works…except jME and the rendering in OpenGL Extension Viewer.



Even Java3D works without any problems!!!



Also I do not expect any of you to do anything about my system :wink:

I am just seaching for some clever hints, so maybe I can rest this case and accept that my Laptop (Dell Latitude XP) does not support some 3D features. I am just so confused because Java3D works and OpenGL test programms all confirm that OpenGL is supported up to version 2.1. How can that be?



The only remarkable (low level) difference between Java3D and jME is that jME uses LWJGL and I believe Java3D uses JOGL. Can LWJGL cause problems while JOGL does not?

7

Can you try running TestSimpleLighting and see what the result is?

Hi Momoko Fan,



since jME SDK throws the above given error message already when started, I tried TestSimpleLighting in Eclipse.

Here is the result:

SCHWERWIEGEND: Uncaught exception thrown in Thread[LWJGL Renderer Thread,5,main]

If I comment out the lines of code where light sources are added to the scene like so:



[java] pl = new PointLight();

pl.setColor(ColorRGBA.White);

pl.setRadius(4f);

// rootNode.addLight(pl);



DirectionalLight dl = new DirectionalLight();

dl.setDirection(new Vector3f(-1, -1, -1).normalizeLocal());

dl.setColor(ColorRGBA.Green);

// rootNode.addLight(dl);

[/java]





then the program runs…but of course without light sources:

Unfortunately, my wonderful, if not brand new, notebook computer that I love and does everything wonderfully, a toshiba satellite P205D-S7802, has an ati radeon x1200 which does not support the kind of shading that JME uses and simply does not have the capability and likely never will.

Oh my.. the piles of shit we have to read through.. xD If you want to support low-level OpenGL just enable OpenGL1, obviously theres no support for shaders in OpenGL1 so you'll have to live without some post effects. And yes, card manufacturers only fix their drivers for the big games and not for jMonkeyEngine, just buy a mac if you want working software and hardware and not prototypes :P Anyway I am happy you decided not to hang out here xD

What he is saying is that the free engine you and all the core team spend hours of your life working on, and then give away for free, for others to make money from if they so choose, is not good enough. And he is going to find a better free engine rather than attempt to contribute to jMonkeyEngine and make it better.



Really, the thing is that the level of technical skill required to make anything from jMonkeyEngine is quite high. This isnt a failing of the SDK or the engine - 3D programming is just difficult by nature. Even with something like jMonkeyEngine where (most) of the hard work is done for you, you are still required to have good knowledge of the 3d pipeline and 3d maths. And 3d hardware. And even then, the problems I have to solve during game development that are not related to 3D graphics - ie which data structure to use or how to generate a random level - are an order of magnitude more difficult to solve than the problems I deal with in business application programming. Thats why its fun!

Godspeed then ;)

Thank you for your replies and your support. I just see all of the hard work and hours going into this project, but then I feel that some of the other people that may not be highly experienced computer programmers or that might not have the best equipment are sometimes a little bit ignored. The only problem with this is that for JME and other open source software to gain greater acceptance and become respected by major developers, it needs to work on older computers and be very stable across a majority of platforms.

Yes, I was a little bit of a jerk. But I saw other people being nice and being ignored. I got some attention to the problem. In the long run, if you want to make a better product for many people to use, you have to spend some time making it work with older equipment. I want JME to be good enough. That’s why I said what I said. Normen is probably right about using an older OpenGL version. That is one good workaround. I also found that simply replacing the ninja object with a teapot object in HelloAssets gets the example running. In general, developers that want JME-based apps to work well with a wider variety of equipment can dumb-down the app with simpler mesh models when running on older equipment.



My apologies for being a jerk. I realize that many people have indeed put many hours into making this excellent product. I just wanted to encourage you to pay a little more attention to stability and wider compatibility. I realize that I insulted a fine group of professionals who, it turns out, are willing to put in the effort to make a very good product. I didn’t mean to put you down personally. Really, I have become so accustomed to dealing with stuck up people that won’t give me the time of day that here i’ve become one myself.

@kaiservadar: Glad you see this in a similar way :slight_smile: The issue simply is that theres an unsurmountable amount of work to be done if we really wanted to fix some of these kinds of issues. If every second driver is broken somehow its very hard to code around all issues. We test the shaders to be 100% compatible to the GLSL specs but theres always gonna be some issue popping up. For low-tier graphics, use the OpenGL1 support layer. jME3 isn’t really meant to be compatible to low-level graphics, its designed for GPU’s that properly support GLSL, think Crysis instead of FarmVille :wink:
