There is a work arround:
1)Try to "Run" povray: this will generate two files: Mesh.inc and tesr.pov without having to view them.
2) You have to stop Povray when it starts (close the xwindow).
For the OBJ files, yon have an area in the corresponding menu for choosing the name on the OBJ file: if it's filed, K3DSurf will generate the OBJ file without loading it in the small editor.

To change the maximum resolution go to:
"Options:Export/Resolution/Optimisation" --> "Resolution" --> "MaxGrid ="
Also, you can use the "Config" option in the menu to enable K3DSurf to have your Maximum grid on the startup. - May 26 2009

Hi,
You can set the grid resolution before generating the mesh:
1) deactivate the button "xyz"
2) move the slider to your resolution of choice
3) activate the button "xyz"
BTW, the maximum grid allowed is 500x500x500 which already need a huge amount of RAM...not to mention the size of the generated Mesh - May 26 2009

You're welcome :)
The next update will require Qt version above of 3.3.4 since I experienced some crashs under windows (it works under Linux with 3.3.4).
Also, suggestions and bugs should be reported here: http://k3dsurf.s4.bizhat.com/

The time compilation under Windows is quite long (45minutes for an Athlon 2GH/256M/WinXP) !
This message is just a warning from GCC and you have to be "very" patient when compiling K3DSurf under windows.

Anyway, Png file format was dropped in Qt4 and K3DSurf will not use this feature in the future to make it compatible with Qt4. Perhaps in the next release I'll make some changes to the code. - Oct 07 2006

The only reason I can see for that is that gcc is using the wrong library to construct the final binary. Do you have Qt4 installed in your system? Perhaps gcc is trying to link this one instead of Qt3.
If Qt3 is installed, then you have only to specify the right path to Qt3 in the last command :
g++ -o ../bin/k3dsurf main.o panel.o Matrix3D.o IsoMatrix3D.o Model3D.o fparser.o edit.o Matrix4D.o Matrix5D.o videoplayer.o Matrix6D.o Iso3D.o IsoPanel.o k3dsurf.o newwindow2.o IsoWindow.o moc_panel.o moc_edit.o moc_videoplayer.o moc_IsoPanel.o moc_k3dsurf.o moc_newwindow2.o moc_IsoWindow.o -L/opt/qt/lib(you have to specify here the right path to Qt3) -L/usr/X11R6/lib -lqt-mt -lXext -lX11 -lm -lpthread - Oct 07 2006

I think I got it. you don't have to change directory to "src" after the "qmake" commande. Just run :
cd k3dsurf-0.5.4; qmake; make;
That all. If it doesn't work, please make a ".zip" or ".tar.gz" file frome your k3dsurf-0.5.4 directory. I have to look at some of the generated files by your Qt configutaion.

Hi,
1)I've made a new Thread on Nvidea forums :

2) use your "nvidia-bug-report.sh" tool and send the report to "linux-bugs@nvidia.com",
maybe they can help us to resolve this prob (for more infos : http://www.nvidia.com/object/linux_display_ia32_1.0-7676.html )
3) I'm not sure but it seems that nvidea released a new linux driver a week ago ( http://www.nvidia.com/object/linux_display_ia32_1.0-7676.html) - Sep 17 2005

Science by virtualmeet 138 comments

It looks like the problem come from Qt multithreading use along with nvidea driver...I'll try to find out a solution but it'll be difficult since no one has reported that prob before and that it depends on specific hardware. Qt forums don't help so much for this (I take a look at Qt Forums but the only advise for such problem was : Qt is not safe when using multithreading along with it's GUI)

K3DSurf v0.5.3 is now available. if it's too slow, try to :
1) set latency to 5ms (More Options-->latency)
2) Activate HSR and reduice it's quality to 1.
Hope this can help.
see you - Sep 15 2005

K3DSurf

Science by virtualmeet 138 comments

My machine is an Athlon 2GH with only 256M RAM and linux versin of K3DSurf use less than 40%CPU at (30x30)... You can accelerate animations by reduicing the "latency" to 5ms (MoreOptions-->Latency).
It's strange that Windows version is slow too (in my config, animation use almost 65% at 25x25). Windows version is 2 times slower than Linux version du to Qt multithread limitations (it wasn't easy to make it work there and sources code are not totally compatibles). K3DSurf 0.5.3 for windows is under work since, like I said before, it needs some tweaks to make it run (you can compile source code provided here for windows but animation and Morph will not work properly). Mac version don't need theses changes. I'm prety sure that the probleme is from an incompatibility between Qt and Nvidea drivers...So, right now, I'm afraid but you have to use parts of K3DSurf that works fine for you(povray mesh generation, view examples...) .
Also, you can can try K3DSurf in another machine (friends ?) to compare behaviors.
Let me know if things get better for you. - Sep 13 2005

K3DSurf

Science by virtualmeet 138 comments

I think that your nvidea driver is not useful for K3DSurf (mine don't have OpenGl acceleration) and anim take less than 30% CPU (grid 25x25). Don't use height grid unless you need to export to POV or other file format. By the way, OpenGl is useful but I don't like the rendering (it's almost impossible to have an accurate rendering for the mesh). OpenGl is almost done but I prefer to concentrate right now on other features.
What grid are you using? - Sep 13 2005

1)You gcc is up to date but only in 3.3 branch...which mean that it use an old stdlib (version 5). There is another branch of gcc, the version 3.4 that use libstd (version 6). I'm not sure this will resolve your problem but I urge you to upgrade your gcc to the 3.4 branch (from Gentoo packages).
2) It seems that your nvidea opengl driver use heavely hadware acceleration even for non opengl programs. try, if you can, disable opengl acceleration to see if the drawing is ok (in general, this option is provided by a prorgam provided with the driver) - Sep 12 2005

Hi,
The screenshoot was made under windows because it works there too. K3DSurf need only Qt, this is whay it works under windows and Mac.
K3DSurf don't need OpenGL since it use only Qt's 2D drawind...
I don't have any idea whay the drawing show only in Mesh...no one has pointed that probleme before...
Please try the Linux binary before to see if it resolve the probleme. If it works, then something is wrong with your compile framework. let me kow what happen - Sep 11 2005

Hi,
Seems this one is different from the Qthread compilation problem...can't tell exactly what happen but the problem seems to be the location of Qt. One solution of this is to remove the Makefiles .There are two: one in the root of k3dsurf directory, the other in src directory (to be sure that qmake will create new ones) and reexecute: qmake; make; command.

Science by virtualmeet 138 comments

Hi,
Thanks for reporting this to me but it's a bit strange because Qthread support is already declared in k3dsurf.pro file and it should be sufficient. Also, the right commande to compile the source code is simply by typing in k3dsurf directory:
qmake; make;
if someone else have the same problem please repoted to me.

You're right, there is a problem with the "^" function because it's equivalent in povscript is "pow". I'm going to fix that soon or completely delete this option since using the parametric description isn't so accurate because the main idea behind K3DSurf is to use a mesh description(for better performance).

Hi,
You can now download Linux binary of K3DSurf compiled with Qt 3.3.3
Let me know if this worked for you. What Linux version do you have?
I think it's too early to install Qt4 alone because the majority of applications don't use it right now and it will take time to do that. I'm working on the translation to Qt4 but it will take from 2 to 3 weeks to do that and it's likely that I will continue to support Qt3.x for at least 2 months. see you - Jun 30 2005
