1  Java Game APIs & Engines / Xith3D Forums / Re: The Getting Started Guide - Go for a split ? on: 2006-05-05 16:21:55
The GSG was intended to be a consistent step-by-step guide such that you can read it like a book. The idea is that new users should have something to start with.

If it helps the GSG in some way you can change the format, but I think it is more important to update its contents and add new sections. The GSG can easily be modified via CVS and Will and I have written a nice ant build file,so if you have LaTeX installed I would just advise you to go ahead. (I guess you can commit new stuff even without having LaTeX, if you just drop someone a note who can compile a new version.) Unfortunately I don't use Xith3D anymore (and haven't used it for a long time), which is probably a reason why the GSG is not in a good state.

I think most questions about ray intersection are not covered in the picking tutorial. In the picking tutorial you have screen coordinates and want to find out, which object is picked given these coordinates. Ray intersection is a more general topic.

Please follow the hints on this page of the guide:

Of course the best thing would be to have LaTeX and especially LaTeX2HTML installed, so you can run the ant build script in the xith-tk CVS and directly update the files in CVS (if you have the permission to do this). Especially if you want to do several tutorials or several small changes this is the preferred way.

However, if this is a real problem I think it is also possible to take an existing tex-file (see link above) and use it as a skeleton. There are just some simple commands (e.g. for including a code block or an image) listed in the link above, which are needed. If you have done a tutorial you can send the tex-file, java-file(s) and images (PNG preferred) to Will or me. (Currently it's probably better to send it to Will as I will have almost no time.)

I use "AI a Modern Aproach from Russel Norvig".

That's a very good book. It is one of the standard references for general AI. However it is not focused on games at all (except maybe some search techniques) and has about 1000 pages, so it is not a quick help. The book has the advantage that it is mostly easy to understand and manages to give you a good overview of most topics without going too much in the details. If you like it, you should go for the second edition, which contains less errors.

IF you try and manually edit exim conf, you discover they have f*cked it up and made their own propriteraty config system for this ONE piece of software.

If you try to use the Debian proprietary config system you find references to lots of variables which are debian specific and undocumented, but have the word "debconf" inside them.

Debconf is supposed to be used to configure all Debian programs. Weird. I'd never used it, never even heard of it. Why? Oh. That's right - there's NO DOCUMENTATION FOR IT.

Well, debconf is the tool, which configures your packages. Were you never asked any question when you installed a package? You can reconfigure your package using "dpkg-reconfigure <package>", where <package> stands for the name of the package you want to reconfigure. If you want to reconfigure debconf itself, then you have to run "dpkg-reconfigure debconf". Debconf only does some basic configuration to make life easier. It does not stop you from editing the config files manually. Actually that's an advantage. If you want real help, then please ask in an appropriate mailing list / newsgroup like linux.debian.user (if the problem is really Debian specific).

The biggest difference between Kerry and Bush is:
Kerry is a thinker; he understands these things are complex. He will take time to find the right solution. Bush is an action guy and that appeals to the less educated portion of our country.  Roll Eyes

I said it once, and I'll say it again. No "international laws" were violated. Bush's decision may not have been popular with certain UN members, (say France, who was profiting quite nicely from Iraq), but it was certainly rational.

The USA did not require UN authorization to attack the Iraq, so your statement is correct. Nevertheless they violated international guidelines and weakened the position of the UN, which is in contrast to the USA an international organization. International organizations are in my opinion better suited to ensure peace in the world than a single country. The USA is the most powerful country of the world, so it's not a surprise that non-US people see it as a threat if they do not behave according to international rules.

No, we haven't found WMD in Iraq. We were working based on the intelligence information we could gather. Since Saddam was playing the fool, we couldn't just go in there and take a look around.

Do you still think there are/were WMDs? (Btw. it's at least strange that the USA is actively developing WMDs.)

Btw, have you ever heard of the Duelfer report? Saddam was conclusively spending the majority of Iraq's budget on the military, while violatiing UN sanctions. Iraq may have been somewhat of a pushover when we hit, but Saddam's intent was to make Iraq a threat - and in very short order.

The Duelfer report states that there are no WMDs in Iraq, but Saddam had plans to strengthen his military force. This was not a direct threat, so there was no urgent need to attack the Iraq. And anyway this report was written long after the war. At the time the USA declared war they did not have this information.

All in all your information is correct, but our interpretations actually differ a lot. Maybe your interpretation is at least partly biased, which is understandable. I do not claim that it was bad to end the regime of Saddam, but I think there were simply better ways to do it (with better investigations, better international cooperation). For me it's a fact that the reasons the US government gave for entering war (WMDs, Iraq works together with Al-Qaida) were wrong. The only good reason was to democratize the Iraq and stabilize the Middle East, but obviously this was not their main goal, because there were no detailed plans for how to do this and the current situation is still far from stable. (I do not know if the oil in Iraq was indeed a major reason for the war, but it is at leat possible.)

There's no question that Saddam wasn't directly responsible for 9/11, but it was Saddam's idiocy which led to Iraq's invasion.

Sorry, but this is naive in my opinion. Bush demanded Saddam and his sons to leave Iraq within two days. It's the first time ever that a president of one country demanded the president of an other country to leave his own country. It was pretty much obvious Saddam wouldn't do this. This really can't justify the mistakes the US government made. (Btw. you can't use actions of a "bad guy" to justify your own faults.)

He refused to submit to our requests by the deadline we gave him, so we went into Iraq to ensure the safety of our country.This was all  "legal" by UN rules, even if certain UN members weren't in favor of the action.

The USA did not cooperate with the UN and other countries and additionally did not have appropriate plans for the time after war. Why does the USA (and only the USA) have the right to violate international guidelines? They clearly acted against the UN.

As it turns out, it was quite a good thing that Saddam acted stupidly. Had you listened to any of the reports delivered in the senate, you would have known that we learned that Saddam was diverting the vast majority of Iraq's income into military funding and expansion. The UN's "food for oil" strategy was a joke. Had we not stopped Saddam immediately, in a few years time, we'd be living in a much scarier world.

In fact no evidence for existing mass destruction weapons has been found and the Iraq was surprisingly weak in this war. There was no urgent need to attack the Iraq.

1.  We believed a war to remove Saddam was right

The US said the reasons for war are that Iraq is a threat to world peace and has mass destruction weapons. Both is actually wrong. They also mentioned something like the Iraq government works together with Al-Qaida, which is obviously also wrong. It's correct that Saddam Hussein is a dictator and there was a need to improve the situation in the Iraq. But in exactly this point the US failed again. They had no concepts and if you watch the news you'll see death and destruction all day in Iraq. Do you really think this was the right way?

2.  Doing it without the support of corrupt UN was right


3.  The fact France didn't like it made it that much sweeter!

That's a non-argument. Btw. Germany was against it, too.

Every industrial nation on this planet has to cooperate with the USA and will certainly do so, but it is indeed difficult.

Whichever way this vote went, it was always going to be a shame that the world's biggest democracy was being run by someone who only just managed to scrape in.  I wonder how it'd feel to live in a country where 50% of people would prefer it if their elected leader wasn't in power?  Must be a very odd atmosphere indeed.

Wasn't it last time that Bush had less than 50% of the direct votes (if people could elect the president directly)? In general it's not a big problem to have only 50% of the voices, but in the case of Bush vs. Kerry the population is split. (Btw. with respect to population India is a bigger democracy than the USA.)

The biggest difference between Kerry and Bush is:
Kerry is a thinker; he understands these things are complex. He will take time to find the right solution. Bush is an action guy and that appeals to the less educated portion of our country.

Most people in the US feel proud if they see their president in army clothes with a real big gun. And that's about all they seem to care about. For me it's very disappointing to see how much votes Bush gets. I have no trust in Bush and the people around him and see them as a threat for the non-US world (in fact most people viewed the US as the biggest threat to world peace even before the Iraq war) . The Iraq war was unjustified, they had no concept for the after-war-time, people all over the world protested against him, his international policy is a nightmare (the relationship to the UN certainly got worse) and he hasn't achieved success in environmental protection and economy. As far as I know the achievements in home policy have also been pretty limited.

I'm quite politically naive about the USA to be honest - I'd sooner see the whole country vanish under a tidal wave and that'd be the end of the problem for the rest of us - but as I understood it, both candidates are pro-war and paranoid about terrorists. So who do you vote for if you're anti-war and not paranoid?

I think with Kerry the chances for unjustified wars is lower. If I understand all these reports Kerry is more rational and less a missionary guided by god to help the world.

There is a resume of Bush's work:  Roll Eyes (SCNR)

In my opinion they are not similar. I hope there will be a change in the foreign policy of the USA towards better cooperation with other countries.

It's interesting to note the importance of the whole military and weapon topic in the USA. There seems to be a lot of fear. In other industrial countries this is usually a non-topic in elections.
22  Discussions / Miscellaneous Topics / Re: Food for thought on: 2004-10-22 15:21:11
By the way, did you know Bush is persuing new WMD's of his own and is currently funding the development of more advanced nuclear weapons?

I don't think the US goverment judges their own country the way they judge others.

That's actually a feature. Grin If you click your overlay at its border it will follow your mouse until you click once more. Long time ago I posted in this forum how this can be disabled. Nevertheless the userinterface package has serious drawbacks (event handling, artefacts in text display, ...).

I really wonder why we haven't started to use an own Forum on an own webpage, so we could have e-mail notification, moderators, etc.
If just I knew more about Internet and network stuff... :-(

In my opinion setting up a forum is technically no problem. If TikiWiki has a forum module it could be directly integrated in (which is the appropriate place for own forums).
26  Java Game APIs & Engines / jMonkeyEngine / Re: Xith vs jME on: 2004-09-19 07:59:58
jME does seem to be more targeted towards first person shooters (at least thats my perception looking at the feature list). Xith was originally attempting to be more generic (a la Java3D).

I'd say Java3D is still more generic than Xith3D. Java3D is targeted towards all kinds of 3D simulations, whereas Xith3D concentrates more on games (it's thread unsafe, uses only floats, doesn't use capabilities, ...), which leads to a better performance.

It would be good to have people using both, Xith3D and jME, so they can provide feedback of the strengths and weaknesses of both APIs. Maybe some kind of official "project goal comparision" would be helpful.
27  Java Game APIs & Engines / Tools Discussion / Re: How do you run eclipse? on: 2004-09-19 05:55:22
Seeing as the following every time creates huge numbers of eclipse threads which grind the system to a halt (even on clean reboot) and eventually kills X and hangs linux (!):

cd /apps/eclipse

and the eclipse executable only works if run from it's directory (sigh; just like DOS). I'd rather like to be able to run eclipse from anywhere on the machine. I'm sure everyone doesn't cd to the directory before running it, surely?

Maybe you called the script above "eclipse" and it is in your $PATH. This would result in the script calling itself over and over again (it doesn't actually hang X or Linux, if you stop it with "Strg+C" and wait some seconds). Replace "eclipse" by "./eclipse".
28  Java Game APIs & Engines / Xith3D Forums / Re: Forum organization ... on: 2004-09-18 16:32:04

This forum gets quite big and it's ever more difficult to locate particular threads. I'm sure there are interesting topics beyond the first 10 thread pages down to page 36 but at least for me it takes too much time to search them all.

What about having another forum called for example "Helpdesk"
where people can post small problems or questions and can check whether their particular problem has already been solved before.

A "HowTo" forum would be helpful to find working solutions to common problems or tutorials.

We discussed about more forums some time ago. With the current activity one forum seems to be sufficient. If we want more forums we can't stay at, because I don't think we'll get another dedicated forum (actually there were proposals to mix 3rd party API forums). Having forums at two places or moving away from is dangerous in the current situation. (If the activity were a lot higher we could do the move.)


My suggestions:
General: To post everything just as it is now.
Helpdesk: small questions and problems
HowTo: solutions to common problems
Demo: People posting their demo and awnser questions on how they did it.

I think is the right place for this. The "Helpdesk" is clearly something like the (maybe "HowTo" fits in there, too). The demos can be presented at the demo section, which is not exactly a forum, but the Wiki is very flexible. For instance you could create one page per demo and put the explanations there. If the demo presents one particular feature, has documented sourcecode and explanations I will happily include it in the Getting Started Guide (see signature).

Your help/interest is very welcome. If you like you could locate some old threads and submit the interesting information to the As far as I know the FAQ can easily be split into Sub-FAQs, if the number of questions increases significantly (currently 17 questions).

The structure is pretty much ready to be filled with more information, but if you have other suggestions just tell them.
29  Java Game APIs & Engines / Xith3D Forums / Re: Xith3D goals on: 2004-09-17 07:36:07
Added paragraph to docs section and edited code conventions page. (I like the Wiki. Smiley)
30  Java Game APIs & Engines / Xith3D Forums / Re: Xith3D goals on: 2004-09-16 12:22:48
Eclipse has the lovely Source->Format option which can do everything for us, but it does make it a bit harder to compare one version of Xith3D to another depending on how many formatting changes this would make.

I like the Source->Format option. Smiley Source -> Add Javadoc Comment is useful, too. Eclipse also has the advantage that the code conventions can be saved in an xml-file. Version comparing can get a bit more difficult, but as the format will only change once per file (depending how much the files differ from the conventions) it isn't such a big problem and makes the code more readable.

I suggest taking the following simple steps:
  • create a simple "(not yet) official code conventions" page at
  • write a paragraph in the docs section linking to this new page
  • create a new thread in this forum where everyone can write down suggestions for exceptions from the Sun code conventions (or more detailed explanations if necessary)
  • after a fixed time span without new suggestions the code conventions become official

Of couse it would also be nice, if people can download code convention files for eclipse (or other IDEs), when they start to differ from Sun conventions for which eclipse has built-in support. Are you happy with this procedure?
