I looking it over now and wondering of there's a quick and easy way to do this. I see a library called keylib floating around, but it seems a bit old. The upstream way of isolating the keyboard mapping from X is called libxbkcommon: http://cgit.freedesktop.org/xorg/lib/libxkbcommon/ Coupled with lib(g)udev for device discovery/hotplug and evdev devices you have a solid base for input events on Linux. What is the recommended way to handle input for Clutter in this case? I've started a branch to support evdev devices called wip/evdev: http://git.clutter-project.org/clutter/log/?h=wip/evdev The evdev event backend works for keyboards, supports hotplug. Next stop, mice (and possibly other devices exposed by the evdev driver). The branch sits on top of master, but it's possible to use the backend on earlier versions (1.4 / 1.2) with fiddling a bit with the build system.

that code was never in Clutter: it was in one of the toys.
nowadays, two years and a half after that code was written, we have
better ways of accomplishing the same result - even in languages that
are not C. :-)
first of all, ClutterCloneTexture has been replaced by ClutterClone,
which can clone all actors, not just textures.
then you don't need to drop into GL to paint: Cogl, the Clutter OpenGL
abstraction library, can do that for you, and more efficiently.
the whole paint() virtual function implementation can be replaced with
something like this:
static void
clutter_texture_reflection_paint (ClutterActor *actor)
{
ClutterClone *super = CLUTTER_CLONE (actor);
ClutterTextureReflectionPrivate *priv;
ClutterActor *source;
ClutterActorBox *box;

clutter_actor_box_get_size (box, width, height);
/* get the composite opacity of the actor */
opacity = clutter_actor_get_paint_opacity (actor);
/* clamp the size of the reflection */
r_height = priv-reflection_height;
if (r_height 0 || r_height height)
r_height = height;
/* figure out the texel for the reflection */
rty = r_height / height;

* full color and the second is the same, but at 0 opacity
*/

cogl_color_premultiply (color_1);
cogl_color_set_from_4f (color_2, 1.0, 1.0, 1.0, 0.0);
cogl_color_premultiply (color_2);

I'm trying to *not* use the gtk bindings so the app stays DE independent. As Emmanuele indicated, windowing is not platform-agnostic; you will need to use whatever APIs given platform provides to do this, i.e., on an X-based system, you will need to use xlib and follow the ICCM (http://tronche.com/gui/x/icccm/) and the EWMH (http://standards.freedesktop.org/wm-spec/wm-spec-1.4.html) protocols.

Could someone else test video-player perhaps? This happens on both Intel and Nvidia GPUs btw. Robert has basically rewritten the way Materials (The abstraction used to fill geometry) work. While the conformance tests are passing, some bugs still need to be crushed, it's so bleeding edge I did not even have the opportunity to test clutter-gst against it (but knew it was likely to break things). Tracking clutter master can be dangerous at times, but thanks for reporting this, it needs to be fixed indeed. Meanwhile, if you need some stable version, can I suggest to use 1.2.10 instead?

Re: [clutter] RFC: Are toggle references neede for CoglHandle ?
On Tue, 2010-06-08 at 13:41 +0100, Neil Roberts wrote: Recently Cogl in git has gained support for attaching arbitrary user data to any handle using a pointer as a key in much the same way as Cairo does. We could use this to attach the Ruby proxy object to the handle so that it could return the same object every time the handle is seen. However if we do this then we need to resolve the issue that both the proxy object and the GObject will need to reference each other yet we still want them to be garbage collected. Most languages that bind GObject seem to use toggle references to fix this. So my question is, should we add toggle reference support to CoglHandles? This would certainly help someone implementing a Cogl texture cache as well, since it is important to know when textures are no longer used.

Emmanuele:
In addition to the notes below I spent the day attempting to get my application

(moblin-2.1-PR-Final-ivi-201002090924.img). This uses the IEGD v10.3 driver.
To do this I upgraded my target platform with this release.
Running my application as built for clutter v1.0.10 on top of this Moblin

- Executed ldconfig on the folder that contained the above files
- Built my application on my Ubuntu development environment.
- Copied my application to the Moblin target system.

try not destroying the stage and returning TRUE. right now, you're

you should actually use the ::destroy signal instead.

In the same, as far as I remember, while I was trying to check it, I mostly compile mutter/gnome-shell using -afc. Anyway, I will try to rebuild everything as you suggested. I will report that soon. That problem might explain why it doesn't crash in a sensible place. The ABI break could make it jump to an invalid address. Well, the two previous cases I had a weird behaviour with Clutter was due NVIDIA drivers, this is the reason I pointed that. Have you tried with NVIDIA drivers?

Re: [clutter] gnome-shell crashes using clutter git master repository
I could also replicate the problem on an nvidia box and I've pushed the patch below which seems to fix it. test-conformance was also failing on nvidia. I messed up the texcoord array caching patch so it wasn't disabling arrays properly and it would probably end up reading stale memory in glDrawArrays. Presumably we were getting away with this on Mesa. commit 401892af1188073dc3107832b8e2e908c5c0e79e Author: Neil Roberts n...@linux.intel.com Date: Thu May 27 14:51:44 2010 +0100 cogl: Record new enabled arrays in _cogl_disable_other_texcoord_arrays When _cogl_disable_other_texcoord_arrays is called it disables the neccessary texcoord arrays and then removes the bits for the disabled arrays in ctx-texcoord_arrays_enabled. However none of the places that call the function then set any bits in ctx-texcoord_arrays_enabled so the arrays would never get marked and they would never get disabled again. This patch just changes it so that _cogl_disable_other_texcoord_arrays also sets the corresponding bits in ctx-texcoord_arrays_enabled. - Neil -- To unsubscribe send a mail to clutter+unsubscr...@o-hand.com

You should be able to do this with a custom material on a ClutterTexture
using multi-texturing. Assuming you have your alpha mask texture in a
CoglHandle and your base texture in a ClutterTexture you can do
something like this:
ClutterActor *base_texture = ...;
CoglHandle alpha_mask_texture = ...;
CoglHandle material;
/* Get the material from the Clutter texture */
material =
clutter_texture_get_cogl_texture (CLUTTER_TEXTURE (base_texture));
maaterial = clutter_texture_get_cogl_material (CLUTTER_TEXTURE
(base_texture));
that could fix the error, afaik...
/* Add the alpha mask as a second texture layer */
cogl_material_set_layer (material, 1, alpha_mask_texture);
/* Set the combine function so that the base texture is modulated by the
alpha component of the mask texture */
cogl_material_set_layer_combine (material, 1,
RGBA = MODULATE (PREVIOUS, TEXTURE[A]),
NULL);
If you need picking to work as well then you would need to subclass
ClutterTextue and override the pick method so that it draws a solid
rectangle masked by the alpha texture in a similar way.
You may want to take a look at Mutter¹ which does a similar thing to
support shaped windows.

Re: [clutter] Sprite Animations
On Sun, 16 May 2010 14:31:30 -0400, Sam Wilson tecywiz...@hotmail.com wrote:
Hello knowledgeable clutter people,
I created an actor to handle drawing sprite based animations, and I am
wondering if it is the correct way to do it.
The code is written in Vala, but it won't compile with the stock clutter
bindings since I am using cogl_texture_new_from_sub_texture which isn't
bound. There's a patch attached to fix it.
The actor looks pretty neat to me. I just have a couple of points that
might make it slightly better.
- There's no need to override the pick method if the actor has no
children and you are just drawing the color to fill the actor's
allocation. The default implementation in ClutterActor will do this
for you.
- You might want to make a separate material for each frame that is
private to the actor and use that to render the texture rather than
using Cogl.set_source_texture. This will help Cogl optimize the
rendering better because Cogl.set_source_texture effectively ends up
editing a global convenience material which would cause a flush of
Cogl's journal. You should also use this material to implement the
opacity of the actor. So _frames would become an array of
Cogl.Materials and your init function would be something like this
(although I don't really know Vala so I'm just guessing the syntax):
_frames[i] = new Cogl.Material ();
_frames[i].set_layer(0, new Texture.from_sub_texture (...));
and then your paint method would be like this:
guint8 paint_opacity = get_paint_opacity ();
_frames[i].set_color4ub (paint_opacity,
paint_opacity,
paint_opacity,
paint_opacity);
Cogl.set_source (frames[i]);
...
- It's currently much more efficient to use Cogl.rectangle rather than
the path API to draw the texture. Cogl isn't clever enough to
recognise that the path you've created is a simple rectangle and it
ends up having to fill the stencil buffer to render the texture into
the path. Using Cogl.rectangle instead means it can just directly
submit a quad to OpenGL.
- You might want to implement the setter for the 'frame' property so
that it queues a redraw. Otherwise it would probably be difficult to
use ClutterActor.animate to animate the property. I don't know what's
the right way to do that in Vala.
Hope that helps.
- Neil

Re: [clutter] Strategies for composing a stage with many small actors
Hello, You can try to animate the anchor-x and anchor-y properties for scrolling. These properties affect only the paint phase, their animation should not retrigger allocation. This will avoid some python virtual method calls. HTH, Julien 2010/4/30 Martin Wilz martin.w...@gmail.com Hello, While not getting any further with my previous post, I tried to draw something with clutter/COGL, which comes pretty near to the use case I have in mind. The stage consists mostly of rounded rectangles as implemented on http://www.themacaque.com/?p=565 and labels, both of them put together in groups. Lots of them. Then I tried to animate it (scrolling ) and my CPU hit the limit and it was nowhere near being smooth. I first thought, that maybe the hardware acceleration is not working (I'm still not sure). I did some debugging and came to conclusion, that there is first an issue with the do_paint method in the rounded rectangle. It gets unnecessarily called, when each actor is moved, as verified by print-debugging. I'm using group.animate(clutter.EASE_IN_OUT_SINE, 1, y, 500) to animate, which I'm not sure is the right way to animate optimally. Are there other ways of moving actors, which are less well documented (e.g anchor points), but don't trigger an redraw of the actors, but work more in the spirit of a transformation of actors rather than redrawing them ? As I did not find such a transformation, I tried to use texture_new_from_actor with my group, as these groups will change slowly and one at a time in the use case. Unfortunately texture_new_from_actor returns None on my system, even for simple objects such as Rectangles. I read something about the system needing the feature to render textures offscreen and checked the feature flags. import clutter f = clutter.FeatureFlags.__flags_values__ for (i,v) in f.iteritems(): ... print %s:%s % (str(v), clutter.feature_available(i)) ... flags CLUTTER_FEATURE_STAGE_USER_RESIZE of type ClutterFeatureFlags:True flags CLUTTER_FEATURE_STAGE_STATIC of type ClutterFeatureFlags:False flags CLUTTER_FEATURE_SWAP_EVENTS of type ClutterFeatureFlags:False flags CLUTTER_FEATURE_TEXTURE_NPOT of type ClutterFeatureFlags:True flags CLUTTER_FEATURE_OFFSCREEN of type ClutterFeatureFlags:True flags CLUTTER_FEATURE_TEXTURE_READ_PIXELS of type ClutterFeatureFlags:True flags CLUTTER_FEATURE_SYNC_TO_VBLANK of type ClutterFeatureFlags:True flags CLUTTER_FEATURE_STAGE_CURSOR of type ClutterFeatureFlags:True flags CLUTTER_FEATURE_TEXTURE_YUV of type ClutterFeatureFlags:False flags CLUTTER_FEATURE_SHADERS_GLSL of type ClutterFeatureFlags:True flags CLUTTER_FEATURE_STAGE_MULTIPLE of type ClutterFeatureFlags:True As I interpret it, my (ATI 4550 with fglrx driver) system should be capable to use texture_new_from_actor. I already made sure the actor is not attached to another actor/stage and to show the actor before. Am I missing something else ? Oh yes, I saw that you are able to draw to textures directly with Cairo, which seems to be the currently recommended way to generate textures. Are there any caveats when using this approach other than having to look at just another drawing API ? Martin

(I think just CLAMP_TO_EDGE) The texture_rectangle extension also doesn't support mipmapping and has limited repeat modes. The big difference with texture rectangle that might explain why they added the extension is that you don't use normalized texture coordinates to sample from them. Normal TEXTURE_2D textures have coordinates in the range [0,1] but TEXTURE_RECTANGLE textures use coordinates in the range [0,texture_width/height]. It can sometimes be convenient to use TEXTURE_RECTANGLE textures in shaders since it's simpler to use them as lookup tables. Using TEXTURE_2D textures involves calculating a floating point delta to allow indexing of specific texels in your texture. Is it a mistake that our GPU vendor is supporting texture_rectangle on GLES? Should we ask them to support OES_texture_npot instead or in addition? (It looks like texture_npot has fewer restrictions than texture_rectangle, anyway, which is nice.) Or is it normal and accepted to sometimes see texture_rectangle on GLES implementations? I don't know if it's a mistake; but unless you want a texture that doesn't use normalized texture coordinates I don't think it buys you anything over the basic support for NPOT textures that GLES 2 already comes with. The Cogl OpenGL backend doesn't really support texture_rectangle it just allows you to use cogl_texture_new_from_foreign with TEXTURE_RECTANGLE and it understands that they don't have normalized coordinates. I would expect for GLES 2.0 you could also use cogl_texture_new_from_foreign to create NPOT TEXTURE_2D textures and avoid having to use texture_rectangle. The problems would be that you can't enable mipmaping for such textures or use anything but the CLAMP_TO_EDGE repeat mode. (Note: if you aren't using Clutter master though you don't have explicit control over the repeat modes so you would need to patch Cogl to work around this.) Getting the same level of support for texture_rectangle as we have for OpenGL should be easy if you want to experiment with it, since most of the CoglTexture code is shared between GL and GLES. You can search for #if HAVE_COGL_GL guards in cogl-texture-2d-slice.c; remove them; tweak _cogl_texture_driver_allows_foreign_gl_target to allow the COGL_TEXTURE_RECTANGLE_ARB target and then you'll have to use cogl_texture_new_from_foreign, which means you have to create the texture manually with raw GL calls and you have to be very careful to restore any GL state you modify while creating the texture so you don't confuse any state caching Cogl does internally. The only reason we have texture_rectangle support for OpenGL is to support texture_from_pixmap on some limited GPUs. If possible I would ask the vendor if they can support OES_texture_npot since that would make your life *much* easier. It's very possible though that your hardware can't support the extension though. Adding better support for the limited NPOT textures that GLES 2 exposes to Cogl could be done something like this: * Make the ensure_mipmaps vfunc for all texture backends return a boolean status so it may fail. * Make the set_wrap_mode_parameters vfunc for all texture backends return a boolean status so it may fail. * patch the texture_2d backend with some #ifdef HAVE_COGL_GLES2 guards: * so that it always returns FALSE in the ensure_mipmaps vfunc. * so it returns FALSE in set_wrap_mode_parameters for anything but CLAMP_TO_EDGE. * patch cogl_texture_new_from_bitmap and cogl_texture_new_with_size with some #ifdef HAVE_COGL_GLES2 guards so we never try and create and return a _cogl_texture_2d directly. * Add a cogl-texture-rectangle backend. This should basically be a copy of cogl-texture-2d.c backend except replace occurrences of TEXTURE_2D with TEXTURE_RECTANGLE. * Adapt cogl-texture-2d-sliced.c to be implemented in terms of
Re: [clutter] switched colour channels
Hi Phil, On Phil gut@gmail.com wrote: I have compiled Clutter 1.2.5 with the eglnative/gles backend. The colour channels of textures seem to be switched when the format is not RGBA. This is my fault. Before Clutter 1.2 we would always convert the texture using the Cogl bitmap code when a Cogl texture is created with a different internal format from the image format. However for 1.2 I changed it so that it would just pass the image format and the internal format directly to GL so that the GL driver could do the conversion. The assumption is that the GL driver is likely to be faster (or at least our code isn't at all optimized so it can't be any slower) and support more formats. I didn't realize that GLES doesn't support the format conversions when uploading data so of course it broke for that backend. I've attached a couple of patches to the bug report¹ which should hopefully fix the problem. Furthermore, can anybody tell me where the convertion should be triggered ideally? As far as I have seen, the _cogl_texture_prepare_for_upload () seems to be the right place. There also, the GL pixel format conversion is invoked, which in turn is performed by the gles specific function. However, I am wondering why no conversion is triggered there when the CoglPixelFormat does not match the GL internal format (since the OpenGL ES does not provide the necessary conversion)? Yes, that looks like the right place and it is indeed where I've put the conversion in the patches.

Re: [clutter] [cogl] Texture slices: what is the waste?
Hi Alberto,
Excerpts from Alberto Mardegan's message of Fri Apr 16 20:11:03 +0100 2010:
Hi all,
I'm implementing some optimizations to some cogl texture functions,
since they seem to have a considerable impact on my application
performance, and I've started with _cogl_texture_upload_to_gl() (GLES
backend).
I added some debugging statements in there, and it seems that the
texture is never sliced in my case.
So, I've implemented the optimization suggested by the FIXME comment,
that is avoid copying the bitmap to a temporary one. Things seem to work
fine, and definitely faster.
Excellent, thanks for taking a look at this.
Before submitting this patch for review, though, I'd like to understand
whether the code blocks introduced by the if ({x,y}_span-waste 0)
condition are also relevant in the single slice case, or if they can be
omitted. I left them out and I'm not noticing any problems.
In short; yes a sliced texture with only one slice can have waste...
First this is a multi slice example with waste:
|Slice 0 | Slice 1 | Slice 2 |
| power of two size |-- POT size --|-- POT size --|
| User's texture size -|- waste |
|-|-|
|o||o|xx|
|o||o|xx|
|o||o|xx|
|o||o|xx|
|o||o|xx|
-
o = user data; x = waste data
A slice is an individual OpenGL texture object.
But a single slice example could look like this:
| power of two size |
|-- Usr tex size --|-- waste -|
|-|
|||
|||
|||
|||
|||
---
The waste is basically used to pad the difference between the power of
two texture sizes and the size of the user's texture data.
When the difference would be too large that's when the user's texture
data gets spread between multiple GL textures (slices). It's the
max_waste threshold that determines when we do this.
So for example if you try and load a 190 pixel wide texture then we
first determine that the nearest power of two size to fit that would be
256 and you'd have a waste of 66 pixels wide on the right. If that's
larger than the current max_waste threshold then instead of loading the
users texture into a 256 wide texture we'd consider loading it into
a 128 pixel texture + a 64 pixel texture. This leaves 2 pixels of waste
on the right of the 64 pixel slice which we'd expect to pass the
max_waste threshold.
If the max_waste threshold were greater than 66 though we would simply
load the users texture 190 pixel texture into one 256 pixel wide slice
with 66 pixels of waste.
Note: the above examples only depict waste along the x axis with the
waste on the right, but it's also possible to have waste on the y axis
at the bottom.
Note: platforms fully supporting npot textures don't ever need to slice
unless you upload textures larger than the GPU texture size limits and
even then they never have waste.
It might be worth investigating if your GLES platform supports this
extension:
http://www.khronos.org/registry/gles/extensions/OES/OES_texture_npot.txt
If so it might be worth patching the GLES backend to check for this and
when it's available OR in the COGL_FEATURE_TEXTURE_NPOT flag.
(you could do this in _cogl_features_init in driver/gles/cogl.c)
I hope that helps,
kind regards,
- Robert

Alberto

Re: [clutter] Using cogl without clutter
Excerpts from Oscar Lazzarino's message of Tue Apr 06 10:59:11 +0100 2010: Hi, would it be possibile to use cogl without clutter, on a gl context created with gtkglext? If so, a small example or some hints would be very useful. Hi, The long term goal is for Cogl to become a standalone 3D graphics API and we are incrementally working towards this goal. Cogl will also have a window system abstraction (only as far as framebuffer management is concerned, I don't mean anything relating input events etc) that could make it possible to integrate tightly with GTK in one way or another. Integrating with a GL context not owned by Cogl adds additional complexity but theoretically it would be possible to create a Cogl winsys that allowed this. Sorry that doesn't really help you, but you might be interested to know it may be possible one day. kind regards, - Robert Thanks O. -- Robert Bragg, Intel Open Source Technology Center -- To unsubscribe send a mail to clutter+unsubscr...@o-hand.com

On Tue, 23 Mar 2010 14:00:50 -0500, Uday Verma uday.ka...@gmail.com wrote:
I am trying to animate a sub-actor inside a ClutterActor but I can't
seem to be able to do so.
I have an actor A which contains several Bs, A is not a container but
a regular actor. I have a add method which adds B to A, and in the
process does B.set_parent (A).
1. When I do so, right after the parenting operation I set the
position and dimensions of B. The position and dimension requests are
not being regarded and according to --clutter-flags=paint, the
allocation of actor B is {0,0,0,0}. I wonder why that is when I am
explicitly setting the size and position. The only way I could get
the actor B to appear was by explicitly setting the allocation of
actor B to the desired location.
Setting the size of an actor just replaces the preferred and minimum
sizes that would be returned by get_preferred_with/height. The actor
still needs to be allocated to get an actual size. Any actor that has
children must implement the allocate method to call allocate on its
children. Your allocate method should be something like this (note I
don't know Vala so I'm just guessing):
public override void allocate (Clutter.Actor actor,
Clutter.ActorBox box,
Clutter.AllocationFlags flags)
{
/* Chain up so we still get an allocation (I don't know Vala's syntax
for this so I'll use C++) */
actor.ClutterActor::allocate (actor, box, flags);
/* Allocate all of the children at their natural size and position */
foreach (var a in children.values)
a.allocate_preferred_size ();
}
You also need to implement paint, pick, map and unmap in a similar
way. You can get away without pick if the children don't need to handle
events and it will work without map and unmap if you always add actors
after the container is mapped (but it's cleaner just to implement them).
