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.

***************************************




Changelog:

MathMod is a new project that is a complete rewrite of K3DSurf, with many new features and optimizations.
Please visit the new project home page at: http://kde-apps.org/content/show.php/MathMod?content=163992

 hyper objects

Score 50%

Any chance of adding support for hyper objects with more than 3 dimensions.

You can use either animation as if taking slices through an object, or shadow techniques where the shadow has three dimensions instead of two.

This would be really cool for helping people visualise object with more than three dimensions.

yes...this is one of my purpose because the shapes from 4D are the beautiful ones..."Klein Bottle" is an example of 4D object who was "projected" in 3D space. In other hand, such delicate object aren't so easy to manipulate. I'm working on it and for any adea or article in the internet that discuss this manipulation, please leave a message. Thanks

What method are you using to generate the images?

Is it not possible to have a 4d object and then transform the functions be a view vector to create a 3d projection.

Other methods you can use are root solving (the povray source is a good place to start looking).

You find one point that has a non-imaganiry solution, then you start walking unit boxes, projecting a ray and seeing if you have a solution along each edge of the box.

this is mainly useful for polynomials but can be used for other objects such as blobs.

Hi,
I'm not using the "Ray tracing" method like povray to visualise 3D shapes because it's as slow as perfect. I'm using the same method like OpenGL ( Matrix transformation of the points that describe the shapes) for it's efficiency and rapidity. What I'm doing now is just projecting 3D points in 2D plan (window):

1)Construct 3D shapes from parametric equations (3 param equations).
2) Project this shape to 2D plan (window).
3) Visualise using 2D drawing functions.


What I'm traying to do is:
1) Construct 4D shapes from parametrics equations (4 param equations).
2) Project this shape to 3D world (our world).
3) Project this shape to 2D plan (window).
4) Visualise using 2D drawing functions.


The projection from 4D-->3D has the same principle than projection from 3D-->2D..the only probleme is HOW to choose the right "3D world" where the 4D shapes can give the best view when projected on it...
Th method you describe is the perfect one but it's not useful for animation (the day where quntum computer will be sold in Supermarket, sure I will review my code ;-) )
see you

You said:
"there still some incompatibilities between windows version and linux QT version . Hope the next QT4 will fix that"
Now you can ! QT4.0 is out !! :-))
I'll try K3DSurf when compiling QT4.0 will be done ;-)

Ooops..yeh, I see that. Thanks for the notice ;-). I'll begin portage to Qt4 in the next days. It's good news for Windows and Mac users because we (Linux users) can now share our Linux application. So thanks to Qt team (from Trolltech).
see you soon

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

Thank you for the linux binaries. The 3D preview is very sweet, accurate and fast, I love it. The parametric export for povray is very usefull !! Great work :-)

 Export to pov

 
 by LightBeam on: Jul 6 2005

Something to change when exporting a parametric:
for example :
1.2^v
must be exported as :
pow(1.2, v)

Povray synthax has changed since v3.5 (or above ?)

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).

How do you like Plasma 5?
 The best KDE Desktop ever.
 Definitely a nice improvement.
 Not decided yet. Haven't tried it yet.
 I do not like some of the changes.
 KDE is taking the wrong way.
 I am still sticking with KDE 3.5.
 I have no opinion, but wanted to vote anyway.
