Science

Description:

K3DSurf is a program to visualize and manipulate Multidimensional surfaces by using Mathematical equations. It's also a "Modeler" for POV-Ray in the area of parametric/iso surfaces.

Features :
* 3D, 4D, 5D and 6D HyperObjects visualization.
* Animation and Morph effect.
* Povscript and OBJ Mesh file export.
* More than 100 examples.

Very useful program.
But what should I do if I want to generate mesh 1000x1000x1000 ? The fact that all parameters are changed with sliders makes this program very slow. Why cant I directly input grid resolution ?

virtualmeet

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

Hmmm... The maximum resolution is 100x100x100. I cant enable 500x500x500.

virtualmeet

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.

Works.

I just want to generate a file for POV Ray, but it makes me view the full resolution surface. Because of it allocates the whole free memory, it's very slow.

virtualmeet

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.

Hello!

Can you tell me the specific steps to do that? I try several times but I don't know which is the menu / field that I have to set up with file.obj

Thank you for this wonderfull program!

Hi. K3DSurf (0.6.1) now build successfully under win2000sp4, Thanks!
It took more than 75 minutes
(Intel 2.4GH/256M).

virtualmeet

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/

This program is very good,it goes
smoothly on the windows 2000. but in
operating the 3d graph Projection,add
the functions:Orthographic Projection,
Perspective Projection,the application
will be better in showing 3d plots.

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.

Hi. Since K3DSurf (0.6.0) now build successfully under Arch, I've already uploaded my PKGBUILD in AUR. I hope you could put a link here. Thanks!

http://aur.archlinux.org/packages.php?do_Details=1&ID=7658

By the way, there's some minor "bug" (well, it's not technically a bug) that I've noticed. You forgot to update the version in the caption string "K3DSurf v0.5.6 : Math for Fun" in src/k3dsurf.ui

virtualmeet

It's corrected and Arch Linux Added in the package list. Thanks for your contribution.

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

I don't think that a QT4 installation would be a problem. In my case, QT3 profile is sourced before the build process. To verify this, I've temporarily uninstalled QT4, then retried the build process. I also don't see why it can't link to the QT3 libs.

virtualmeet

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.
