@gordon
Yes, thanks, I updated the code so that it uses < ?php ?> instead of < ? ?>

I also got rid of “echoText()” so now you just echo out the results of “getText()”, which makes more sense
Also, if you’re interested i would recommend making a function that accepts an array of textID’s, and makes a SINGLE SQL call that returns an Array of text to prevent multiple SQL calls. (I will update later)

As to your passing the variable around from page to page. Either store it in a SESSION variable or load it from stored User information.

Hey, could someone give me an idea on how to pass this ?lang=jp value when the user switches the page? Would apreciate that very much

Hey, Jorrit. I got the same problem and found a simple explanation to it. For those who receive output of the index.php in the browser like this
echoText(’LANG_EN’, $lang); ?>|echoText(’LANG_JP’, $lang); ?>|echoText(’LANG_ZH’, $lang); ?>
and so on….

the problem is with the short_open_tags used in the code

so simply replace all the short tags with full (NB: this conserns only open, not closing tags)
OR
enable short_open_tag in the php.ini file of your server.

P.S. Sorry if my English is bad somewhere, cause I’m not a native english speaker

can you print out the error?
in case it’s a DB error just change
mysql_query($sql);
to
mysql_query($sql) or die(mysql_error());

You said created the Database, are you sure that you inserted the appropriate text_id’s?

Thanks Ken! I try to use your script for a school assignment. I created the MySQL database. When I try to run the script, there is something wrong with the echoText. In each line i get this mistake. What could be the problem? Thanks in advance

In terms of performance. For a small website, there probably won’t be much performance issues. However,On a page where there are many text fields being displayed + lots of users, you would not want to make a million different SQL calls. Instead you would want to modify the code to query ALL the text fields on the page in a SINGLE QUERY, load them into an associative array, then display them.
I think this would be more efficient.
Thanks for your input, I will make a more “efficient” version of this later. what do you think?

What´s better performance?, gettext or a db solution like? i appreciate any help.

It seems that the code is of high quality, although I can’t judge because I’ve just started learning PHP and MySQL, and I’d say you’re using object oriented programming which I don’t have a clue about, at least for now. Also the code seems to allow for additional features later if needed.

Anyway, thank you very much for this tutorial—it’s been stored in my bookmarks to reference it when I’ve learned the above mentioned language/database management system to the point where I’m able to understand the code completely.

Comment on 4D Rotation Matrix - Graph 4D by NeuroFuzzy

NeuroFuzzy — Wed, 09 Dec 2009 04:40:54 +0000

I’m planning to have a 3d-to-2d camera, which the user views through a standard camera, controlled by the movement of the mouse. The 3d world will be given by a 4d-to-3d camera, IE 4D lines intersecting a 3d cube, as opposed to 3d lines intersecting a 2d plane.

If things get too complicated, doe to the nature of euler angles (problems like gimbal lock, and odd rotation patterns), i might limit the program to rotation on the YU axis, for now.

Besides that, i’ll definitely take a look at all the source code, it might be really helpful

No problem. and yes these rotation matrices only describe the rotation around a specific Axis. You would need to derive a rotation matrix for rotations around any given vector (which is possible, though I honestly am not sure how to do this off the top of my head),

Refer to my 3D rotation matrices page and note that I use quaternions to define a rotation around any arbitrary axis as it is simpler. I’m going to guess that there exists a similar method for mapping 4D rotations.

As for a 4 dimension object viewer, I will be uploading various 3D function and 4D function/object viewing software I recently flung together in C++. They have correspondingly contain a Vector3D.h and Vector4D.h file with some useful rotation functions. and getUnitVector() functions.

Also, about a 4D viewer, since 4D is not directly viewable you will have to come up with some “creative” way to represent it. for example, taking a “slice” of the 4D object, which is 3D and displaying it. So in a sense draw multiple slices. Or do something like change the color of the dot depending on it’s 4D value. so High 4D values represent a White pixel and fade to Blue or Black as the values go more negative. Etc.

Also dig through the source files (included in the JAR) on this page and you’ll see how it all works.

thank you for the fast reply! I’m trying to make a 4 dimensional object viewer, and I’m wondering how many different user inputs i would need to be able to be able to show all possible rotations of a four dimensional object. Euler’s rotation theorem states that you only need 3 angles to describe an arbitrary rotation, but that only applies to 3 dimensions. I guess that i’ll start out using the result of six rotation matrices… but i really don’t want to if i can use fewer.

>NeuroFuzzy
No. It just means that there are 6 different elementary ways to rotate a 4D Vector (X, Y, Z, U).
Possible rotations in 4D space include:
X vector around the Y
X vector around the Z
X vector around the U

Y vector around the Z
Y vector around the U

Z vector around the U

So this leaves 6 rotations, (of course removing symmetric rotations. i.e. XU = UX, YU = UY, etc)

in 5D space (X, Y, Z, U, W) you would then have

X vector around the Y
X vector around the Z
X vector around the U
X vector around the W

Y vector around the Z
Y vector around the U
Y vector around the W

Z vector around the U
Z vector around the W

U vector around the W

for a total of 10 rotation matrices.

hmm… does this mean that to express any four dimensional rotation, you need 6 angle values?

Thanks a lot! This is the best explanation of this feature I’ve found on the Net. I had to include a PHP script that I wanted to have localised in a WordPress installation that uses qtranslate and this works perfectly fine.

Thanks for this very helpful page.
Please note that formula 2a is erroneous. The numbers on the matrix diagonal should all be squared, i.e. q0^2+q1^2-q2^2-q3^2 etc.
I haven’t used the programming code so I have no idea if the code is okay.
