Zhu3D 2.9.8

Version: 2.9.8
Type: Scientific

Description:
 With Zhu3D you interactively can view and animate
functions, isosurfaces and a further independent
parametric system. Numerical solutions of equation
systems can be found with a precise and reliable
adaptive random search. The OpenGL-viewer supports
zooming, scaling, rotating and translating as well
as filed lightning or surface properties. Special
effects are transparency, textures, fog and motion
blur.

Besides the built in functions and constants you
can define your own ones. These user defined
functions can have an arbitrary amount of
parameters, can be nested or even be recursive.
For special purposes the function parsers support
if-conditions and boolean operators.

You have up to eight independent lights or
spotlights, background settings, miscellaneous
wire-modes or global illumination models. Pictures
are rendered as PNG, JPG, PDF or PostScript and
can be of arbitrary size. For textures Zhu3D
recognizes nine common formats. Isosurfaces can be
visualized with different volume-based algorithms.

Zhu3D runs under Linux/Unix, Windows 98/XP/Vista
and Mac OS X and is localized for English, German,
Spanish, French and Chinese. It supports different
CPU's as well as different API's like KDE, Motiv,
Gnome or Windows. All settings can be changed
dynamically at runtime. The application comes with
extended help files and a lot of examples.

COMPILING:

All you need is Qt >=4.1 and support for OpenGL
>=1.2. The latter can be a software implementation
like Mesa. The qmake easily can be taylored for
special needs, what supports packagers.

HW-REQUIREMENTS:

For basic viewings even an old and slow PC without
hardware accelerated OpenGL is sufficient.
However, enabling goddies like animation, big
textures and especially motion blur is a challenge
for every GPU out there. On the other hand
isosurfaces with dense meshes need a lot of
CPU-power.

VERSIONS:

Whatever ends with an odd number, is considered as
"pre". Those versions are not intended to be
unfinished or buggy, but my testing capabilities
are limited to my own HW/SW-configurations. So
especially packagers may wait for an even number.
A complete Windows version is available - special
thanks to Victor Fernandez, who is hosting this!


Have fun, Heinz van Saanen

Changelog:
 What is new in 2.9.8

- Executing a File/New-command command during a
running animation of a parametric system resulted
in a slightly incorrect screen. Fixed
- Axes legends for x,y,z where a bit too big when
compiling with Qt 4.3. Shrinked them for nicer
proportions
- Raised the maximum number of user-defined
functions to 32
- Some rather cosmetic changes in the source
- Polishing some examples, readmes, ...
- Switched license to GPLv3

What was new in 2.9.6

- A comment with # can appear anywhere in a
function input now instead of just at the
beginning
- Added missing hyperbolic area functions (asinh,
acosh, ...) to the parsers. The hyperbolic example
works now as expected
- The solver showed a wait cursor, when it was not
successfull. Corrected

NOTE: The packages below may be behind the
original src.tar.gz of course. There are some more
packages outside. But these are not mentioned
here, as they are hopelessly outdated.
