[vtk-developers] IRC Chat (9/3/2002)

Tue Sep 3 10:54:48 EDT 2002

Hi All, 

Unfortunately I missed first 10 minutes of the chat.
Here it is the rest:

Sep 03 10:09:36 -->	You are now talking on #vtk
Sep 03 10:09:36 ---	Topic for #vtk is VTK devel meeting at 1400 GMT
Sep 03 10:09:36 ---	Topic for #vtk set by burp at Tue Sep  3 07:52:08
Sep 03 10:09:39 <burp>	It's probably not interesting for anybody but
Andy.
Sep 03 10:09:41 <legoandy>	Hello
Sep 03 10:09:46 <burp>	legoandy: Hallo Andy.
Sep 03 10:09:53 <legoandy>	Sorry I'm late but I am still on Monday
time...
Sep 03 10:10:25 <legoandy>	burp: what are you talking about?
Sep 03 10:11:28 <prabhu>	hi!
Sep 03 10:11:46 <legoandy>	Looks like latency today really high...
Sep 03 10:11:59 <prabhu>	I also have a couple of questions.
Sep 03 10:12:05 <prabhu>	sorry I'm late too.
Sep 03 10:12:16 <prabhu>	Sorry also about the delayed announcement
Sep 03 10:13:10 <burp>	legoandy: Your posting on vtk-devel... I just
wanted to note that python 2.1.3 compiled with SGI (MIPSPro) C and VTK
compiled with MIPSPro C++ work fine on office-mate's Octane with Irix
6.5.
Sep 03 10:13:50 <prabhu>	burp: i.e. vtkpython (the interpreter) works?
Sep 03 10:14:11 <legoandy>	burp: Can you run vtkpython and import vtk?
Sep 03 10:14:56 <prabhu>	and also use the Tkwidgets?
Sep 03 10:15:06 <prabhu>	hello?
Sep 03 10:15:19 <legoandy>	prabhu: your solution for TkWidget does not
work on Apple
Sep 03 10:15:48 <legoandy>	For some reason I am getting the same problem
on Apple but the solution might not be as easy
Sep 03 10:15:53 <burp>	prabhu: Sorry, doing many things at once.
Sep 03 10:16:21 <legoandy>	maybe we could link both
libvtkCommonPython.so and libvtkCommonPython.dylib
Sep 03 10:16:24 <prabhu>	legoandy: yes, I saw your post but what if the
libvtkRenderingTkWidgets thing were compiled to be a .dylib?
Sep 03 10:16:59 <prabhu>	yes so we'd need some if APPLE kind of thing in
CMakeList.txt ...
Sep 03 10:17:04 <burp>	prabhu: Hmmm, office-mate is not using vtkpython,
but just python with all paths appropriately set...
Sep 03 10:17:26 <prabhu>	burp: but then do the tKwidget work then/
Sep 03 10:17:39 <burp>	prabhu: That's untested.
Sep 03 10:17:49 <burp>	prabhu: I misread the "vtkpython" bit.
Sep 03 10:17:55 <prabhu>	i.e. what happens when he runs
vtkTkRenderWidget.
Sep 03 10:18:26 <burp>	prabhu: It seems he doesn't even build the tcl
bits... only python.
Sep 03 10:18:35 <burp>	prabhu: Sorry. :(
Sep 03 10:19:00 <legoandy>	prabhu: I think you need to have .so for
python to work but I am not an apple person anyway
Sep 03 10:19:21 <legoandy>	prabhu: I just want to setup VTK built with
everything on Apple
Sep 03 10:20:17 <prabhu>	I believe andy's original problem occured only
when Tk was involved.  Right Andy?
Sep 03 10:20:56 <prabhu>	hmm, Starreveld is the expert on that.
Sep 03 10:21:01 <legoandy>	prabhu: No. I am not able to even do "import
vtk"
Sep 03 10:21:17 <legoandy>	prabhu: David had similar problem
Sep 03 10:21:25 <prabhu>	on apple?
Sep 03 10:21:35 <prabhu>	Is this recent -- did it work earlier?
Sep 03 10:21:35 <legoandy>	prabhu: Looks like interpreter does not get
initialized properly (On SGI)
Sep 03 10:21:46 <legoandy>	On apple it just does not compile
Sep 03 10:22:07 <prabhu>	even if you use vtkpython?
Sep 03 10:22:51 <prabhu>	I think I'm lost having no experience on apple
and sgi. :(
Sep 03 10:23:10 <legoandy>	Ok, one more time
Sep 03 10:24:16 <legoandy>	On SGI using Sgi's compiler for python and
VTK, everything compiles but when I do "import vtk" in vtkpython I get
"Fatal Python error: Interpreter not initialized (version mismatch?)"
Sep 03 10:25:08 <legoandy>	On Apple, during compiling I get something
about missing vtkPythonUnmanglePointer
Sep 03 10:25:09 <prabhu>	Ok.
Sep 03 10:25:09 <prabhu>	I thought you got around this by creating
vtkpython
Sep 03 10:25:09 <prabhu>	that was a special interpreter built with c++
and linked to all the vtk libs?
Sep 03 10:25:24 <prabhu>	I get that on linux too.
Sep 03 10:25:45 <prabhu>	so I added the libvtkCommonPython to the
CMakeLists and it fixed everything.
Sep 03 10:25:56 <legoandy>	prabhu: Yes, but that solved problem on Sun
and HP
Sep 03 10:26:09 <legoandy>	prabhu: Looks like Sgi has a problem in
Python 
Sep 03 10:26:17 <prabhu>	You mentioned about the .dylib so maybe we
should link with the .dylib also.
Sep 03 10:26:31 <prabhu>	ahh
Sep 03 10:26:46 <legoandy>	prabhu: libvtkCommonPython only exists as .so
Sep 03 10:27:00 <legoandy>	prabhu: maybe we could generate both .dylib
and .so
Sep 03 10:27:09 <legoandy>	prabhu: oh apples...
Sep 03 10:28:08 <legoandy>	burp: Could you test it and let me know?
Sep 03 10:28:35 <prabhu>	IIRC David said that he too needed to create
something like vtkpython to get things working on SGI.
Sep 03 10:28:36 <prabhu>	oh.
Sep 03 10:28:36 <prabhu>	IIRC this vtkPythonUnmangle stuff came up after
the recent addition by Dan.
Sep 03 10:28:38 <prabhu>	legoandy: Is that easy to do?
Sep 03 10:28:42 <prabhu>	legoandy: generating .so and .dylib?
Sep 03 10:29:03 <legoandy>	prabhu: maybe, I will try
Sep 03 10:29:12 <KenMartin>	OK Folks, are other issues?
Sep 03 10:29:26 <prabhu>	yes
Sep 03 10:29:29 <prabhu>	testing for python
Sep 03 10:29:34 <KenMartin>	go ahead
Sep 03 10:29:38 <prabhu>	I think this week  I;ll be able to manage
something
Sep 03 10:29:44 <prabhu>	I want to know a couple of things
Sep 03 10:29:44 <legoandy>	Can we take the vtkImageDataToTkPhoto out,
because it does not compile?
Sep 03 10:29:56 <legoandy>	Oh... sorry
Sep 03 10:29:59 <prabhu>	legoandy: YOu should really ask Dan. :)
Sep 03 10:30:07 <legoandy>	Looks like it is fixed...
Sep 03 10:30:21 <prabhu>	(1) I plan to add the testing interface to
Wrapping/Python/vtk/test
Sep 03 10:30:33 <prabhu>	Now where do I stick the tests in?
Sep 03 10:30:47 <legoandy>	Why not in Common/Testing/Python?
Sep 03 10:30:53 <KenMartin>	Are the tests organized by toolkit or is the
same test used for all tookits?
Sep 03 10:30:58 <prabhu>	I'd like to start adding simple tests for the
widgets 
Sep 03 10:31:09 <prabhu>	There are few tests for the vtkTkRenderWidget
etc.
Sep 03 10:31:27 <KenMartin>	I'd put those in
VTK/Rendering/Testing/Python
Sep 03 10:31:29 <prabhu>	hmm each toolkit will need to be tested 
Sep 03 10:31:58 <KenMartin>	We put gloabl tests (such as PrintSelf) in
VTK/COmmon/Testing/Lang
Sep 03 10:32:23 <KenMartin>	Toolkit specific tests we put in the
VTK/Foo/Testing/Lang directory
Sep 03 10:34:19 <KenMartin>	Other issues?
Sep 03 10:35:15 <KenMartin>	OK, Going...
Sep 03 10:35:35 <KenMartin>	Going...
Sep 03 10:35:56 <KenMartin>	Gone...
Sep 03 10:36:06 <KenMartin>	Thanks Folks
Sep 03 10:36:18 <prabhu>	separately
Sep 03 10:36:18 <prabhu>	besides everyone will not have every toolkit
Sep 03 10:36:18 <prabhu>	so maybe just a Tk test for now will be run
Sep 03 10:36:18 <prabhu>	the rest should be there but not run.
Sep 03 10:36:20 <prabhu>	If you need to run all the toolkit tests you;d
need to have Wx, Tk, Gtk, and Qt.
Sep 03 10:36:22 <prabhu>	which might be a big pain.
Sep 03 10:36:26 <prabhu>	So I'm thinking of a tk test alone (and Tk
seems the most problematic anyway)
Sep 03 10:36:28 <prabhu>	questiuon is where do i put it?
Sep 03 10:36:30 <prabhu>	rendering/testing
Sep 03 10:36:32 <prabhu>	ahh
Sep 03 10:36:34 <prabhu>	ok
Sep 03 10:36:36 <prabhu>	sounds good
Sep 03 10:36:40 <prabhu>	I'll work on a first cut
Sep 03 10:36:42 <prabhu>	commit it this week (hopefully)
Sep 03 10:36:44 <prabhu>	and then put in a few tests 
Sep 03 10:36:48 <prabhu>	Sounds ok?
Sep 03 10:36:54 <prabhu>	Toolkit meaning Rendering, Hybrid etc.
Sep 03 10:36:56 <prabhu>	right?
Sep 03 10:36:58 <legoandy>	Yes
Sep 03 10:37:00 <prabhu>	thanks.
Sep 03 10:37:04 <prabhu>	burp: logging?
Sep 03 10:37:08 <prabhu>	thanks ken!
Sep 03 10:37:15 <KenMartin>	Bad Lag
Sep 03 10:38:24 <KenMartin>	Thanks Prabhu, hopefully next time the lag
will be better.
Sep 03 10:38:37 <--	KenMartin (~ken at tripoint.kitware.com) has left #vtk
