Loops in pipeline

Hello,
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:
http://www.k-3d.org/wiki/Visualization_Pipeline_Loops
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.

Hello Hibou,
I saw you did a fair number of posts to the forum a few months ago. K-3D currently is in a "slow" period, and I lost track of the forums, but if you're still interested, drop me a line and I'll reply to your posts in detail.

Hi Bart,
Yes, I am interested in K-3D as an alternative to something which disappointed me.
I had a look at K-3D some time ago, due to its relation with RenderMan (I am in favor of standards, and RenderMan is a standard). I may be have a deeper look at it now for some other reasons (to see if wither or not this can fulfill some kind of expectation I have).
If you are interested in some kind help, I may be yours; for French translation, as an example, if you are interested in… can't really tell right now about developing, as I did not even had a single look at the source so far (for developing, I would optionally welcome any sponsoring from users, as I am jobless).
Well, I have to go for a deeper look-back at K3-D now (and eventually, if possible, reply to an interesting question a user recently posted here).
P.S. Are you the main developer of K-3D ? (seems you are, but better ask to be sure).
P.P.S. You Mug video tutorial was very cool, looks very professional :)

As you may have noticed, development has been slow for the past year or so, due to Tim and me having other stuff on our hands. Tim has even gone as far as making a clean break from the project, leaving me as admin.
Basically, I want to make sure the project survives, so if you want to help, you are free to choose whatever is most interesting to you. If you give some more details on what you'd like to do, I might be able to point you in the right direction.
I don't know what version of K-3D you are using, I've just submitted a few compilation fixes for the latest ubuntu to the main repository.
Cheers,
Bart

As I said, I cannot assert/promise anything. I will just have a quick look at the source, and for a start, at least build one from source (cheese). I wanted to post something to help integration into Ubuntu Gnome, but I revised my mind to first check what's the state of the latest version in that regard (there was no *.desktop file with the 0.8 I installed, while it seems there is one in the source I get from both Mercurial repositories yesterday).
Please, I have to pending questions :
What should I mainly look to : your repository at GoogleCode or the official one at SourceForge ?
As K-3D is GPL, does it implies any plug-in have to be GPL too ? (probably depends on the technical way plug-ins are plugged into K-3D).
About you saying “make sure the project survives” : I agree too, this would be sad to leave it as dead (and forgive me if I believed it was, and I only saw your reply here due to a hope during a moment of sadness). There is surely provision for a place for a K-3D along Houdini, Maya and Blender (can be interesting if that does not simply copy any of the latter). But please, keep in mind I can't promise anything, the only one thing I can assert right now, is that I will have look at it (I am currently on the way to).

Best is to look at the sourceforge repository. At this time, both are the same, but if I start experimenting with things again it will be using the google repo, with "production" changes going to the sf repository.
Plugins are loaded using dlopen, which means they have to be GPL as well if released. Currently, all plugins are in the K-3D source tree, and if you will develop plugins that are of general interest, I'd recommend doing the same and share your repository somewhere, so I can pull changes when ready.
This is open source, so no promises are needed - do what you want if and when you feel like it, the main thing is that you have fun ;)

Okay,
I may not talk in this forum for some time, before I have anything interesting to tell, may be months… this will not mean I have dropped any interest in K-3D. About the license matter, will have a deeper look at the technical side (would be nice if it was LGPL, this could open more opportunities, while I am neither sure of this finally).
Also thanks for your version of the mug in another thread, the perspective is nice, I will study yours.
