0.9.4
- Ported to Qt 4
- Two new languages: Italian and Portugese
- Cleanup autotools files
0.9.3

- fixed crashing on floating-point errors (we just ignore these qt-originating
errors)
- fixed translation detection in windows

0.9.1
- code cleanups

- spilling foxes
- different user mechanism for rotating cubes with pointer help
(idea from Marek Wieckowski)

- fixed detection of image location during execution
- added translations: spanish, polish, danish
0.9.0 (Cube it! --- see http://www.vandenoever.info/software/cubetest)
- Rewrote question generator: all questions are now answerable without rotating the cubes.
- added different levels of difficulty
- added 'magic angle' for better animation
- added 'restore question' button for easy revision
- added possibility for different styles (.png, .jpg or .svg images) (see docs)

0.6.1
- English translation of documentation
- small fixes
0.6.0
- Improved animation of rotating cubes significantly.
- Added translation to English
0.5.0
- Added automatic generation of questions. Some cubes need to be rotated to
tell the difference.
- Added the KDE make files for easier (?) compilation.
- Allow the cubes to be rotated after the answer has been given.

Nice game!

Though, couple of suggestions,

QT4 has anti-aliasing support. Try
painter.setRenderHints(QPainter::Antialiasing);

The $QTDIR/include directory has to be included, not just $QTDIR/include/Qt

It is not quite obvious when the direction of movement toggles between horizontal and vertical. Perhaps, you can rotate the cube, when the mouse is dragged, in the direction of mouse movement.

Thanks for your suggestions!

Anti-aliassing is nice, but make rotation much slower on old computers. Therefore, I've not enabled it. I might add an algorithm that determines anti-aliasing feasibility in the future. I don't want to make it an option, because I want to keep the user interface simple.

Moving the cubes intuitively is hard. I've played with several concepts to do this. An important aspact for the rotation in this game, is that it should be very controlled. One must be able to rotate only around defined axes. You suggestion might fit with that idea though. I admit that especially in the middle of the cubes the direction can change easily. That's why the mouse cursor changes. If i let the direction depend on the drag direction, then I cannot use the mouse arrow indication anymore. But I need that because dragging can only differentiate between 2 directions and we need 3 (x,y,z).

By the way, if you're reading this and would like to contribute a translation to cubetest, I'd be very pleased.

Well, I know Hindi, but don't have Hindi fonts on my system. Plus I have never done a translation before. Anyway, I will give it a try, and mail you if I get anywhere.

About navigation, you can perhaps look at how 3D modeling programs do it. For eg, Wings-3D.

About anti-aliasing, I truly appreciate your concern for older hardware, though I don't know what exactly you mean by old. And I don't know how efficient QT4 is, but I remember spinning a cube, with images mapped on its faces, on a 60Mhz 486, at about 40 FPS (without anti-aliasing), back in my college days :)

Right ho,
Harshad

As of version 0.9.2, a windows version is available. Qt makes it very easy to port this application to other supported platforms. On my (rarely used) Windows XP, the app runs fine. However, some people without the capacity of provinding debug info have told me the app crashes when one manipulates the cubes.
I've enabled floating point exceptions under Linux to track the bug, but sofar without result. If anybody has the same problem, please try to help me with this problem. You can download the free Turbo Debugger from Borland to do this. If you need a version of the app with source code compiled in, please let me know.

I'm glad you like it!

Of course all comments for improvements and of course translations are welcome!

CubeTest is now converging towards 1.0 and hopefully into distributions. I already spotted it in gentoo.
