### Greg Bernhardt

Using Latex on PF has now never been easier! Thanks to the hard work of member https://www.physicsforums.com/member.php?u=40201". For the meantime I am interested in any performance issues you may have related to the feature.

Could this possibly be the best news of the year?

(I don't think so. The best news will of course be Latex preview.)

Good job, -Job-, and the rest of the PF team!

I'm not sure if this is a bug... under 'Common Snippets' I see Distance Equation and Euler's Constant, but clicking either displays the word 'something' within tex tags.

Wow, this is awesome. I haven't tested thoroughly as I would like, but when I expand a category, I find that I cannot suppress it by clicking the minus sign. [Using firefox].

But its a nicely integrated feature. Thanks -Job-!

Edit: thats Sigma Greg.

Now i just need to figure out how to use latex

Great work!

$$\alpha\beta\chi\delta\epsilon\phi\varphi\gamma$$
$$ABX\Delta E\Phi\Gamma$$
looks Greek to me... but not Greek-alphabetic order.
It looks more like English-first-letter-alphabetic order...
\alpha\beta\chi\delta\epsilon\phi\varphi\gamma

What's a \varphi ?

$$\varphi$$

Oh, got it.

This is very cool. Thanks Job!!!

This looks just like MS's equation editor that I use in Word. Is it related somehow?

10. Jun 27, 2007

### Staff: Mentor

I hadn't heard about that Fred. Is it a standard part of Word, or is it an add-in package?

11. Jun 27, 2007

### -Job-

I would remove the common snippets group until it has some useful commands. I left it as pasting "something" because i couldn't remember the distance equation.

Also, you might find that some commands don't work in this forum, i'm thinking of the formatting commands, let me test that:
$$\LARGE hello, this doesn't work \footnotesizeor does it?$$

The reason for that would be because PF processes all LaTeX as if in a math region (am i right?), and the formatting commands don't work within a math region from my experience.

Also you might find that the reference is missing some LaTeX commands. I copied the list of commands used in TeXniCenter. If you come across some that are missing let me know so i can create icons for them and include them in the next release.

$$d\ =\ \sqrt{(x_{2}\ -\ x_{1})^{2}\ + \ (y_{2}\ -\ y_{1})^{2}}$$

I can't say that it is standard, but it has been part of every version I have owned.

If you go to INSERT and then OBJECT, you will see in the list MICROSOFT EQUATION 3.0 (or similar). Insert it and the tool bar will pop up automatically.

It is an option available at installation for Office [including Word and Powerpoint], but it's not selected by default [at least in Office 97, 2000, and 2003]. With the installation media available, it could be installed when requested for first use. (So, those who make images for computer-cluster machines [for universities], please make sure you select it.)

Wow, thanks -Job- !!!

Maybe -Job- has some ideas about how to fix the Latex preview... :!!)

18. Jun 27, 2007

### ranger

I think Greg mentioned that having latex preview would create the burden of extra/wasted bandwidth.

19. Jun 27, 2007

### Staff: Mentor

That's too bad. But why would previewing Latex be any more of a bandwidth hog that actually posting the Latex? And the previewing is only temporary. Of course, I have no idea how preview works anyway! Guess I'll have to add that to the already large and growing list of things I don't understand.

20. Jun 27, 2007

### Greg Bernhardt

Chroot thought of an idea to resolve this problem, so it's just up to him to start it :)

21. Jun 27, 2007

### -Job-

So why doesn't latex render on the post preview again? I thought this was intentional by Greg and chroot.

I'm starting to develop another plugin for doing pretty much what chroot did for PF, which might take me another couple of months.

I have http://www.latexlab.org [Broken] under development which can be used for previewing i guess, but in-site preview would be much better.

Yeah, sorry guys, I can fix the latex preview. I'm just swamped with school and work and all and haven't gotten around to it. Now that I know there's a huge demand for it still, I will try to get on top of it.

Does any know how it worked before?
And, possibly, where specifically it is broken?
Otherwise, it seems it's not asking for a fix but for a new solution.

[edit... I see that some replies have snuck in while composing]

In my opinion, $$\LaTeX$$ support is very important. It is a feature that attracted me to PF.

I think that $$\LaTeX$$ support while composing replies is also important... especially when it was feature that was available before. These days, I am less likely to post a reply to a post which could benefit from the use of $$\LaTeX$$ because of the broken preview. If I am so compelled to compose an answer, I'll write it locally on my computer, then recode the tags for posting to PF.... but that's sometimes proves too much trouble.

(While I'm on my soap box, I'd like to suggest support for SVG and for something like LiveGraphics3D (a .jar file from http://www.vis.uni-stuttgart.de/~kraus/LiveGraphics3D/ which could be hosted on the PF server)... as seen on MathWorld, e.g. http://mathworld.wolfram.com/Hyperboloid.html ) or possibly JavaViewLib for Maple http://www.javaview.de/maple/index.html )

Pictures are worth a thousand words.
Interactive animations or visualizations in 3D... are worth a lot more.

Okay, okay, I'll fix the preview. The 'problem' is that the hooks that vBulletin provides are not quite in the right places to make the preview easy to implement. I will work on it.

But...but you belong to PF. I honestly can't see how anything else is more important
