dear list,<br>
<br>
I spent some time with tkzinc using the python wrapper<br>
and its pretty great...<br>
<br>
see end of this page for a short demo of a zoomable interface (well the
rest is all in french sorry)<br>

<br>
it's a bit of a pain to compile tkzinc on osx though (but it's feasible)<br>
<br>
the developpers of Tkzinc say that they will release another version
soon (which will drop bindings to X11 and will integrate better support
of bitmaps and svg) - and it might be easier to port to osx but <u>that
is not</u> their priority (apparently)<br>
<br>
another possibility which i am investigating is using pyglet:<br>
+ very close to opengl<br>
+ it's pretty active<br>
+ really cross-platform <br>
- does not provide with all the geometrical transformations and gui
power of tkzinc<br>

for it, try it out, and report any experience you might have.

<pre wrap="">hi list,
is somebody still aware of this. i mean like having it on the agenda/
taking care of it. i'm sorry for not doing it. as i so far dont have
experience in programming it might wouldn't be a good idea to let me
do that ;) i wasnt even able to follow the whole discussion. but there
seemed everybody seemed to match there has to been something on that
field.
i just wondered if anybody is doing anything on this. (maybe 2 people
are doing same things on different channels - i dont hope thats the
case...).
thanks for not getting me wrong in advance.
regards

<pre wrap="">yeah that's what i said about two years ago...
the problem is, at the moment tcl/tk is embedded quite deeply into
Pd
itself. this is a focus of the current pd-dev effort: trying to
clear this
up. tcl/tk in itself isn't _necessarily_ slow, it's just that the
way Pd is
using it is not at all optimised (for example, as Hans-Christoph
and i
discovered once, when you click-drag to move an element in a
graphical
table, not just the element you moved but _the entire table_ is
redrawn,
each time).

<pre wrap="">
It's slight worse, even. The entire table is deleted and re-
created
on each change, not even just redrawn. That said, I am guessing
the C+
+ code on the GPU (Live) will always be quite a bit faster than
Tcl/
Tk
on the CPU. One of the ways that Live is able to make things fast
is
by ignoring the native widgets on each platform and coding their
own.
Tcl/Tk is the best GUI toolkit I've seen for making native-feeling
apps while writing cross-platform code.
If Live is really just blasting bitmaps to the screen, that is
something that Tcl/Tk can easily do. But I am not sure that it
would
be the fastest way to implement GUI widgets.
If someone wants to help this situation, I think the best thing to
do
would be to create some GUI objects using TkZinc. Then we'll have
Tcl/
Tk on the GPU and that should make things quite a bit faster.

<pre wrap="">Wow, hadn't heard of TkZinc. That looks incredible. Another cloud
for my Pd heaven : ). As I've been writing, I'd really love to
create
GUIs entirely with Data Structures - I'm not sure how much of a
performance hit that causes but the opportunities for customization
are much richer when it's turtles all the way down (where turtles =
Pd). Is TkZinc feasible for replacing the whole GUI? It seems to
support all the platforms Pd does.

<pre wrap="">That is something to find out. It sounds promising. At least it
would be possible to write a TkZinc canvas which works like data
structures, but uses OpenGL.
