DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support pip 21.0 will remove support for this functionality.

[Matthias B. <mat...@gm...>]

Hi Gary,

thanks for the clarification.

Just out of curiosity, which functionality of the package are you
planning on using?
I was actually thinking of dusting off the package and also get rid of
some parts that I think are less useful anyway (such as that entire
scene part and some library bindings).
I would then also try to move from Boost.Python to Pybind11 and rely on
a compiler that supports at least C++11. This would eliminate the
dependency on Boost and make the build process more lightweight. There
would then be no runtime dependency on a binding library anymore and the
above problem would go away.

Cheers,

Matthias

Hi Mickael and Matthias,

Upon building and installing cgkit 2.0.0 (non-light) for Python 2.7 on an Ubuntu 16.04 platform I encountered a similar import error when attempting to run cgkit programs since I had only installed the libboost-python-dev package.

The libboost-all-dev package also needs to be installed.

[Matthias B. <mat...@gm...>]

Hi Mickael,

sorry for the delay. That symbol looks like it's from Boost Python, so
you have to make sure you link against the correct libraries. Could it
be that there are several versions of Boost installed and there has been
a mixup between headers and libs?

Hi,

I've been trying to get cgkit working for the past couple days. I've
followed all the instruction and tried on both Ubuntu and Fedora. There
doesn't seem to be any problems during setup but I always get the following
error when trying to run a program that worked for others. Here's the error:

Re: [cgkit-user] viewer.py simplescene.py error Python3.3.5

Hi,

sorry for the delay.

Someone has already provided a patch that changed the PIL imports so
that Pillow can be used as well. So far, this was only in the py2k
branch (and it wasn't released anyway), but I have merged it into the
py3k branch and pushed the changes.
If you want you could get the Python files from the git repository and
check if it works for you. I have also applied the other changes you
posted earlier. Thanks for that!

Is that OpenGL Boost error you are getting also related to PIL/Pillow?
Did the error go away once you changed the imports?

Cheers,

Matthias

I think the problem rather is that in Python 3, the dict object doesn't
have a has_key() method anymore. That should be written as:

  if interface in interfaces:

Could you try changing that line and see if it then works again?
Let me know if that fixes it.

I don't have pygame for Python 3 on OSX (unfortunately, on pygame.org
there is no version for OSX), so I think I never tried this out myself.
On the Python 2 branch I'm actually using "e.unicode" instead of "e.str"
and I can't remember anymore when/why I changed this.
You could try changing it do e.unicode and see if that works again. If
it's not working, you could try printing dir(e) to see what attributes
are defined on the Event object. I'm not sure if maybe something changed
between pygame 1.9.1 and 1.9.2? (there is not much information about
1.9.2 on the website)

Hello,
I think this problem is Shift_JIS ("cp932").

it works.

Re: [cgkit-user] Cursor mask for two tablets simultaneously?

[Matthias B. <mat...@gm...>]

Hi Ryan,

I have never worked with two tablets at the same time, so I'm not sure
what the correct way of doing this is.
But if you already have two separate contexts that each is connected to
a different device, isn't that enough to differentiate the events?
Why would you still need the movemask? (I'm actually not sure if the
movemask is used to distinguish between devices)

I'm afraid if you need more details about the individual fields of the
context or packet object you'll have to check the actual wintab
documentation (see section 7.3, for example):

http://www.wacomeng.com/windows/docs/Wintab_v140.htm

Cheers,

Matthias

[cgkit-user] Cursor mask for two tablets simultaneously?

[Ryan M. <rya...@gm...>]

Hello,

I'm trying to use two Intuos 5 tablets (simultaneous input from each) to
move two cursors at once in pygame.

I thought that I would be able to do this by initializing two separate
contexts and using the context.movemask to specify which cursors could
create move events for each.

I haven't been able to get movemask to work in the way I thought it would.
Specifically, the first tablet's stylus is identified as cursor 2 using the
info commands, and the second tablet's cursor is 7.

I'm not exactly clear on how to use the cursor mask command, but when I set
it to movemask = 2, it doesn't have any effect.

I am, however, able to specify which device can create movement events in
the context.

It occurs to me that the way I'm trying to do this is entirely incorrect,
but either way I could use some help.

Below is the code for each context.

class Tablet1(object):
    def __init__(self, screen, hwnd=None):
        self.hwnd = pygame.display.get_wm_info()["window"]
        self.context = wintab.Context()
        self.context.pktdata = (PK_X | PK_Y | PK_CURSOR)
        self.context.movemask = 2
        self.context.device = 0
        self.context.open(self.hwnd, True)

class Tablet2(object):
    def __init__(self, screen, hwnd=None):
        self.hwnd = pygame.display.get_wm_info()["window"]
        self.context = wintab.Context()
        self.context.pktdata = (PK_X | PK_Y | PK_CURSOR)
        self.context.device = 1
        self.context.movemask = 7
        self.context.open(self.hwnd, True)

Thanks,

Ryan

The cgkit installers only work with the Python version from
www.python.org. So if you want to use the installers, you have to get
Python from there and install that one instead of the one from homebrew.

The alternative is to get the cgkit sources and build your own version
against the version of Python you want to use. See the docs for
instructions how to build the package (depending on what functionality
you need, you may even get away with a pure Python build which doesn't
need any external libraries).

Cheers,

Matthias

[cgkit-user] Installing on OSX Mavericks

[π <sun...@gm...>]

Hello CGKit people,

I've recently discovered Python from having to generate my own Blender export scripts, and I have instantly taken to the language.

I'm very keen to get CGKit up and running on my OSX Mavericks MacBook Air.

First I try to see if I can install using pip, and I cannot.  Then I learn that I need python 3.3, so I install it using Homebrew:

piBookAir:pi_hrtf_23feb pi$ brew install python3

==> Pouring sqlite-3.8.3.mavericks.bottle.1.tar.gz
==> Caveats
This formula is keg-only, so it was not symlinked into /usr/local.

Mac OS X already provides this software and installing another version in
parallel can cause all kinds of trouble.

OS X provides an older sqlite3.

Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:

    CPPFLAGS: -I/usr/local/opt/sqlite/include

Could it be finding the Python3 hiding in Blender? I don't see how; that is not in the path.

Now I run the installer from http://sourceforge.net/projects/cgkit/

But it fails saying Python 3 is not installed.

http://imagebin.org/index.php?mode=image&id=297981

I don't know how to proceed now.

Is there any chance that CGKit could be revised so that it can be installed with pip3?  It is so smooth when all necessary packages can be installed with pip!

Re: [cgkit-user] cgkit with ubuntu 13.04

[Baptiste L. <bap...@gm...>]

Yes, thanks, I managed to build it, that was the right option. I had a
small problem linking to lib3ds, but I eventually found the right line in
setup.py (LIB3DS_AVAILABLE = True). Sorry for asking kind of beginner
question, and thanks for this piece of software and fast answer. I have now
a nice 3D display of a kite simulator.

Where did you get the cgkit binary from? It looks like it was simply
built against a different version of boost than what you have on your
system. So you either have to build cgkit yourself with the version of
boost you have or you have to get boost 1.46.1 from somewhere.
