@ karim: I’m not involved in pigment and elisa (now called moovida) in over two years now. You are much better off trying to contact the upstream developers on the official pigment- and moovida-mailing-lists (https://lists.moovida.com/mailman/listinfo)

Hey,
I am a new pigment user and I am developing a plug in for Elisa media centre and I am having problems in writing widgets code ,
I have wrote a code that creates only a SectionMenuControl and a decorator that draw a link in it ,that’s all

I want to use the widgets in the pigment toolkit but i don’t seem to get can any one help me ,i have searched for a tutorials on how to do it and nothing came on.

For the record Pigment is now under LGPL (since last summer).

@ mallum: Yeah, that licence-issue is a big one. I forgot that in my comparison-list. And that’s why I would currently not consider using pigment for my own personal stuff or stuff that’s meant to be used "outside" of a Fluendo-project. I told that a few people at Fluendo. We’ll see if they reconsider it. I hope so. The 3D-capabilites of pigment and clutter don’t really satisfy my needs (or better… wishes). But I know that both libraries are work-in-progress so that’s ok. The bindings I don’t care for that much personally (I really still don’t like Python :). I just stated them for people who might be interested in something different than C or C++. Since I will meet you at GUADEC (hopefully) anyway we should continue talking about these kind of things - and clutter in particular - there. There’s a lot of topics I would like to bring up.

Arg, I just stumbled on this post and comments, and theres actually a few things wrong and important things missing from your feature by feature comment. Namely;

- Both are O/S but Clutter is LGPL and Pigment is GPL (https://core.fluendo.com/pigment/trac/browser/trunk/LICENSE.GPL?)
- Clutter is in no way strict 2D, its always done 3D!!
- Clutter also has Perl and Mono bindings (as well as python)

I could go on but I wont

@ Stojance: Most of my stuff is available. Check Projects or my page at fdo. The sources of my python/pigment learning-exercises are everything but helpful. They are mostly embarrassing, because I'm still learning python and know nothing of python's best practices yet. If you want to get into python-coding with pigment just go and grab a recent pigment-release from here.

Hey MacSlow!

It wouldn’t be a bad idea to release the code on these programs that you make. I really like to learn how these things go, OpenGL, Cairo and stuff. There aren’t much examples laying around, you know.

@Macslow: That’s quite interesting, actually - I didn’t realize they were even more similar than I imagined. Guess I now have to take a closer look at pigment too. I echo your sentiments that it would be nice if they’d join forces, but I do realize this takes a lot of effort from both projects - I’ll be the last to judge them for it.

Thank you for the comparison.

@ obi: That’s true. clutter and pigment kind of cover the same use-cases for such a library of that kind. Also feature-wise they are very similar. But I’m not very experienced yet with clutter. Also my experience with pigment is still very young. pigment is actually written in ANSI C using gobject. Furthermore it provides a python-binding, which is used by Elisa, as does clutter. Here’s a rough feature-by-feature comparison:

- both implemented in C
- both leverage gobject, gstreamer, OpenGL
- both offer bindings for Python
- clutter already interfaces with cairo/pango, pigment will also start to do so in the next weeks
- placement/rotation-wise clutter is strict 2D only at the moment (that might change), pigment is 3D
- both heavily developed, commercially funded and OpenSource
- clutter there’s already a gtk-widget, for pigment this is planned
- both will be able to support gtk-widgets on surfaces/drawables once gtk offers offscreen-rendering
- both have a pluggable rendering-backend (e.g. OpenGL, OpenGL|ES, directfb…)
- both offer keyframed animation
- clutter offers path-based animation, pigment will soon too
- elisa (not pigment) will offer integration of backends like Ogre3D, OpenSceneGraph or the like
- pigment will offer fragment/vertex-shader and GLSL support, clutter will perhaps too

To my current knowledge this list is quite complete. But I’m always glad for corrections/additions.

It’s a bit sad to see these two efforts pulling in the same direction, but not joining forces. Maybe this will change in the future… please note that this is pure speculation/wishing from my side.
