Description:

Zhu3D is an interactive OpenGL-based mathematical function viewer. You can visualize explicite functions, parametric systems and isosurfaces. The viewer supports zooming, scaling and rotating as well as filed lighting or surface properties. Special effects are animation, morphing, transparency, textures, fog and motion blur. Equation systems can be solved with a fast adaptive random search.

You have up to 8 lights, background settings, wire-modes or different illumination models. For picture rendering and textures all common pic-formats are recognized. You can define your own customized functions to any desired complexity level, nested or even recursive functions inclusively. For special purposes if-clauses and boolean operators are supported. Isosurfaces can use different volume-based algorithms.

Zhu3D is originally designed for *nix-systems, but runs as well under Mac OS X or Windows 2000-Vista in all 32/64 bit-flavours. It is fully localized for English, German, Spanish, French and Chinese and partially for Czech (Gui only). API's like KDE, Gnome, Motif, Mac OS or Windows XP/Vista are supported natively. All these settings as well as most others can be changed dynamically at runtime. The application comes with extended help files and a lot of examples. A precompiled and ready-to-go Windows version is available.

HARDWARE:

For basic tasks even a really slow and ancient PC without HW-OpenGL may be sufficient. However, neat things like motion blur, morphing or isosorfaces are a challenge for every GPU/CPU out there. Zhu3D automatically utilizes up to 16 highly optimized parallel threads therefore. When compiling by yourself, you easely can enable vectorizing with SSE3 as an additional boost-option.

COMPILING:

All unnecessary dependencies are strictly avoided. So compiling is a mere child's play at your fingertips. Everything you need is Qt >=4.3 and OpenGL >=1.4 whereas OpenGL may even be a pure software implementation like Mesa. The qmake easily can be taylored for special needs, what supports packagers.


Have fun, Heinz van Saanen




Changelog:

What is new in 4.2.6

What was new in 4.2.4

- Fixed a very unlikely but possible memory-bug in the XML-file saving/loading-part
- Fixed a very unlikely but possible memory-leak in speedit.cpp
- Fixes for the timestamp-counter on newer platforms
- Slightly optimized some default window positions after the 1.st start ever
- Made settings-stuff more elegant throughout the code what shrinks the executable size too

 Qt 4.x or qt 4.1.4 ?

 
 by trisz on: Aug 1 2006
 
Score 50%

I installed the qt 4.0.0 downloaded from trhe Trolltech's site on the folowing systems:
Suse (SLED 10)
Debian testing (2006. January)

Both of them give the following error message:

/usr/bin/uic-qt4 src/maincontrol.ui -o ui_maincontrol.h
/usr/bin/uic-qt4 src/light.ui -o ui_light.h
/usr/bin/uic-qt4 src/material.ui -o ui_material.h

/usr/bin/uic-qt4 src/animat.ui -o ui_animat.h

./ui_animat.h: In member function 'void Ui_aniUI::setupUi(QWidget*)':
./ui_animat.h:85: error: 'class QProgressBar' has no member named 'setOrientation'
make: *** [main.o] Error 1

Then, I istalled the qt 4.1.4 version downloaded from trhe Trolltech's site.

Zhu3d can be compiled only with this version. If I were you, I reinstalled the qt 4.0.0 version, otherwise Zhu3d could be compiled only on unstable linux versions.

There is another problem present:
The characters in the menus are too small to read it (4-5 pixels), so I can navigate only seeing your screenshots.
Why does not Zhu3d use the system settings?
I use Nvidia's driver. I suppose you have another card. After installing the Nvidia's driver, the character sizes must be heavily enlarged for the system.

Add Qt4.0) This was the initial release and is one year old. So an update will not harm:-) Quite sure it works from 4.01 or so.

Ad Fonts) I tried this out now. Indeed Qt is quite unimpressed, when changing font-sizes. I will consider this in a future release. For now, add this in main.cpp (after the initialisation!) and change the pixelsize to your needs:

// Set fontsize
QFont sysFont=QApplication::font();
sysFont.setPixelSize(14);
QApplication::setFont(sysFont);

"Quite sure it works from 4.01 or so."

QGLPixelBuffer (i guess you're using this now for rendering) requires afaik Qt4.1, so compiling on Qt4.01 will probably fail

No. For rendering I used a QPixmap, which should work fine in older verions too.

 packages for Suse

Hi,
first i want thank you for great program. I use a lot Grapher (http://en.wikipedia.org/wiki/Grapher) and IMHO zhu3d is only program for linux which can match this program.

I created packages for SuSE. Packages are available here:
http://repos.opensuse.org/science/
It is link to repository which can be added to yast.
Or you can click for a while to find rpm packages :)
You will need QT4 which can be found here:
http://repos.opensuse.org/KDE:/Qt/

openSuSE packages updated to 2.7.4 They are for 10.0 10.1(SLE{S,D}) and 10.2

I have some ... enhancements.
Examples. Your program is quite capable, it will be worth to show this by examples. It could be bunch of zhu saved files. I can create some of them if you like. Examples will need some menu for easy access though (no file browsing for show them)

Keep great work

 Runs on amd64

Nice program! I just compiled Zhu3D on Gentoo from the Sunrise overlay on my amd64 computer and it worked fine - any chance you (or whoever the maintainer is) could add ~amd64 to the package keywords?

A amd64-keyword has to be added by the Gentoo-packagers. I somehow wonder that this build is still running, because it is based on a "ancient" 2.3 version. If anything should be odd, compile it by yourself, where you can add the flags easily too. Regards, Heinz

Just a thought... Maybe you two could work together to produce a super killer app. I know, I know, Zhu3D is based on QT4 and K3DSurf is based on QT3. But it would be nice if both of you could share ideas and skills to develop a KDE4-based app. I believe the APIs are stable now. Just my two cents.

hi guys i have been solved the problem with the qt4 debian unstable package with this:

$sudo mv /etc/alternatives/qmake /etc/alternatives/qmake-qt3

$sudo ln -s /usr/bin/qmake-qt4 /etc/alternatives/qmake

when u install qt4 he don't change the simbolic link in 'alternatives' and when you try to run qmake, you create the Makefile with a qt3 version

Only one clue. Maybe you are using the "wrong" qmake for Qt 3.x. You can check this with:

qmake -query "QT_INSTALL_PREFIX"

Do you like or dislike Ubuntu Unity?
 Yes, unity is alien technology!
 It is less confusing than Gnome 3 default, shell.
 Granny thinks it is much more usable than Gnome 2
 Canonical is embarrasing itself with this split project
 Gnome 3 default shell is much better
 I dislike Unity, Gnome 3 default shell is alien technology!
 None of the above, I like the 2Gb for free and Apple alike behavior. Will post a comment instead
