qbot2640 on "Rendering"

I have just installed k-3d (, and so far I am impressed, but how do you render? I keep getting a message about choosing a render engine, or something like that, but no information appears to exist about how to do that.

I'm using the program in ubuntu 12.04

Also, while I'm at it... I have changed my view to a 2D side view...how do I go back to the north east corner view that it starts with?

Sting_Chameleon on "K3D Viewport Problem - Windows 7 64-bit"

I have a problem when viewing the viewport after opening up the program.

I open it up, and I had a message pop-up to tell me this must disable desktop composition to run it. I click 'OK', and this messed the viewport up badly. Everything that's buffered in it is instead copied from what was last in that general area except the mouse, and this is with the 'Disable Desktop Composition' check-box enabled. It looked fine and looked like it'd work without it enabled, but the program keeps forcing the 'Disable Desktop Composition' to be enabled after I close/click 'OK' the first update pop-up on start-up, which takes up that weird effect right after.

I can't work with this, and I even tried to set it to work in 256 colors, but it took out most of my navigation inside the program. It fixed the buffer problem in the viewpoint, but everything else is far too hard to work around.

If this helps any, the graphics card I currently have is "Intel GMA 3100", but when checking the statistics, it meets the display requirements needed for the program. No matter where I look, I cannot find any answers on this matter. I don't know if it's the graphics card or if it's the program's force in disabling the desktop composition. How can I fix this?

The current version of K3D I currently have is Thanks in advance!

PS - I did look in the wiki for the answer, but that didn't help at all. In fact, it's the opposite of what I wanted to happen.

Hibou57 on "Scripted nodes: a basic question"

Hi people out there (except spammer bots)

I wanted to have a try with scripted nodes. I created a DoubleSourceScript node, and gave it a script whose content is this:

import k3d
context.output = k3d.time

Unfortunately, whatever the time I move to, Output Double always diplays 0. What's the proper way to do this?

admin on "How do I configure K3D?"

Wanted to know how to solve an issue I get after I've installed K3D 0.8 on Ubuntu Precise, via Synaptic. Whenever I hit an help button, it complains there is no application configured for the URL, while I have two browsers installed. I could not find any K3D configuration menu to tell K3D a browser is installed and which one to use.

Similarly, I was looking for a configuration option to tell K3D to save the UI layout. Each time I restart K3D, the UI layout is restored in its default state, and does not seems to be save globally nor on a file basis.


Normally, this used to respect the desktop settings for Gnome and KDE. My guess is that whatever we did is deprecated now and this is a bug I need to fix.

I'll have to experiment a little with the GUI myself to see what's the problem there, I'll keep you posted.

I've created these as the first issues on our github page:

CheRepara on "irc; (free-as-in-freedom) community support"

why dont u create IRC Chat rooms?
for a pity its a main lack of the 90% of "free-as-in-freedom" software after incompleteness and bugs - poor support :)
i think it could b quite HELPFUL 4 EVERY1, if there r 2 irc channel groups - for users and for developers
for example at least #k-3d and #k-3d.dev at FreeNode, even better would b with locale rooms like #k-3d.de or #k-3d.ru or #k-3d.cn etc, achieving some MORE BILLIONS of people around the world

im an artist and a hobby-programmer, and i ve been looking for a "free-as-in-freedom" alternative for 3ds max
as i ve seen screenshots of K-3D, i was quite EXCITED, it looked much better simpler and much more logically/intuitively than blender
but almost nothing worked(win xp + knoppix), and soon i was totally desperated running in a circle from link to link in the project's wiki, the "native laguage support" page isnt really understandable

for a pity, it happens too often: starters of such projects, having BEAUTIFUL IDEA, dont realize, that MANY PEOPLE not really advanced but ENTHUSIASTIC could INVEST their TIME and BRING the project FORTH, writing small pieces here and there, if it would b really free-as-in-freedom of this "linuxoid" complicated antinatural git svn rtfm wtf asd qwe go-googl crap and if there would b more alive natural conversation possibilities with at least nice&knowing other community members

best wishes for u and ur project, its a BEAUTIFUL IDEA, it would be quite a pity if it dies because of absent FREEDOM of the most stupid of linuxoid traditions
i SINCERELY hope that ur project survives and grows to 1.0 and further

P.S. i would b really quite glad to help u, for example with localization (for example of this wiki), best of all i speak german & russian but can help u also with some other languages - for free-as-in-freedom ;)

Ianaconi on "Urgent - Beginner"

Hello guys!

I am doing a paper for university about K-3D.

I need you help asap please.

How can I make "union", "difference" and "intersection" with K-3D?

I need to show that.

For example, placing a cylinder and a sphere inside... And make it so just the part that both solids have to show (intersection). http://upload.wikimedia.org/wikipedia/commons/thumb/4/45/Set_intersection.png/180px-Set_intersection.png

And difference: http://www.povray.org/documentation/images/reference/diffobj.png

F4LLCON on "Deleted one part of the polygonal cylinder? HOW?"

Hello there,
I'm new to K3D. I tried out lots of 3D software, by far K3D is the easiest one to work with. I never really build something in 3D so this is in other words my first time really using 3D software.

So my question is, how can I delete one side of a polygonal cylinder? When I select it and then delete it, everything is deleted. I also used 'unparent'. Did not work either.

StevenD on "How do I get RenderMan engine installed"

I'm new to this K-3D app so I have lots of questions but the first one has to do with seeing a preview and rendering. When I select Preview from the Render menu I get a dialog saying "Choose a render engine to be used for preview image rendering".

"RenderMan Engine" is what shows. When I click OK I get another dialog that says "You must choose the specific RenderMan implementation to use with this render engine".

What am I supposed to do to get this up and running? I have been looking for directions from the web site on what to do but can't see anything.

I am working with on Ubuntu 11.01. I just installed K-3D last Thursday. I am an artist/designer and not an engineer. I have been looking for something usable to help with some sculpture model ideas and this one looked like it might be the easiest to work with. That is it for starters.

yopyop on "How to import older K3D models ?"

as I am looking into archives (circa 2005) of datasets, I ran into .k3d files. I downloaded k3d software, only to find out that those files are not supported by the current version of the modeler.
What I want to do is to convert those files in an open standard format - COLLADA - so I can archive the files in a format that I will always be able to open in the future.
I seems that K3D has a COLLADA export features, so how do I get those older files into K3D modeler?

Note: this is a serious business need, so I will consider offers to do the conversion for a fee.

pablob on "Spiral cross-section"


I'm quite new to K-3D and 3D modeling in general. I can deal with polygons and straight edges more or less fine by now, but I want to make a pipe with a spiral cross-section. I guess I could try to make a spiral NURBS and extrude it, however I don't always get lucky with NURBSExtrudeCurve and I don't think I can draw a good looking spiral by hand. Any ideas?

Thanks a lot!

Hi. I'm using K-3D (Version to view 3D models created by others.

I've managed to import .DAE files just fine, but haven't figured out how to import .OBJ files.

I'm also not sure how to add textures to the models. The texture files are all .PNG, and there is also a .MTL file included.

I'm very new to all of this, and feel quite overwhelmed by how complex it all is! Any help would be very appreciated! Thank you. =)

micron_rt on "building under Windows using VS"

I've made an attempt to gather the dependencies for k-3D and I got stuck at building gtkmm. It seems that they don't have any more the support for building gtkmm under Windows with Visual Studio (docs aren't consistent with the actual package). I suppose that for Windows release you're using Mingw. Or is there another way?

Hibou57 on "Loops in pipeline"


To see what will happens, I tried to create a loop in a pipeline. I expected an error notification from K-3D, but did not get one (there no crash too, an that was good).

Then later I saw the page:

Ok, now I know why I did not get a message from K-3D. I understand the rational behind this (no crash), but I believe raising an alert box and refusing to apply an accidental loop, could be a better option. Better an alert so that the user know he/she did something wrong, than silently doing something else which the user will not predict.

Note aside: this pipeline oriented design is clean, that's nice.

It appears at least version, does not duplicate the camera any more. So the “should probably” is not meaningful anymore here, and the whole sentence should be removed.

jonny on "Additional Cameras and 3D"

Hi there,

I am new to using KD-3D and I am currently following the tutorials to increase my knowledge of using this beautify piece of software. However I am posting as I have a question I wish to ask. I am hoping to start making a short animated movie within the next couple of months. I would also like to make this a 3D movie like you get at the cinema either encoding it as an analglyph or stereoscopic video.

I have the additional software to do this however it requires a left and right video file to encode it into a meshed single video file. Does KD-3D have the capability of rendering a sequence into a 3D movie file or can you add an extra camera and render the output of this camera as either the left or right channel.

Any help would be great,
