Re: [osg-users] osgviewerwx for wxWidgets 2.9.0+

Re: [osg-users] Two rotations on an object?
1. Put your sun at the origin of world co-ordinates. 2. Put the planet at the origin. Make its axis of rotation the z axis. 3. Use a rotate transform to rotate it around its axis. (You've got this part.) 4. Translate the planet along the x axis, to its orbital radius. 5. Use a rotation around the z to position the planet in the x-y plane. (If the planet's orbit is not in the x-y plane, you will need more transformations.) These techniques are covered in most introductory computer graphics texts--that's where to go to learn about this kind of problem; studying software docs won't get you very far.

Re: [osg-users] OSG debugging tips
Surely these are FAQs? Randolph On Apr 18, 2009, at 10:48 AM, Paul Martz wrote: Hi all -- It seems like there has been a rash of help me debug my code-type questions lately, so I thought I'd post a short list of debugging techniques and other aids to help people out. I hope people find this information to be useful. 1) You are a software engineer and you have the OSG source code. Use it. Step through it in a debugger. (Many of the posts I've seen lately indicate that the poster has not looked inside the OSG code at all. This is a great, free resource; learn to use it. The code doesn't lie.) 2) For simple rendering problems, use a tool like GLIntercept to capture the OpenGL calls. If you know OpenGL, this is a great way to track down why things don't render correctly. If you don't know OpenGL, buy the red book and learn it, otherwise you'll never be effective at coding OSG. 3) Here are a few ways to learn some basic OSG concepts that get covered in this email list very frequently: a) Buy/download the Quick Start Guide http://www.lulu.com/content/paperback-book/openscenegraph-quick-start-guide/ 767629 There is a color version, bw (which is cheaper), PDF (which is free), and a Chinese version. B) Search the mail list archives: http://groups.google.com/group/osg-users?hl=en If you're a beginner, your question has probably been discussed and answered multiple times. C) Get familiar with the OSG wiki: http://www.openscenegraph.org 4) If you really need professional help, consider purchasing a support contract from myself or Robert Osfield, or contracting with someone else on the list for support.

Re: [osg-users] OpenGL 3.1 at GDC
I don't think the OSG is ready for an all out marketing assult on the games market. There are soft targets that will be the easy sell - these are the ones to court first, leave the hard core Windows centric games companies till much later. The desktop market share is changing with Windows loosing market share (i.e. XP + Vista + Windows 7), and the alternatives are gaining, so the desktop gaming landscape is becoming fragmented, and made more fragmented if people want to target different graphics API's for each platform (i..e DX9 for XP, DX10 to Vista + Windows 7, OpenGL for Linux + OSX). OpenGL can help hold back some the impact of this market fragmentation. Perhaps some gaming companies might be willing to offer OSG development grants, though? It's to their advantage to keep the platform open. Randolph ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Dear OSG Community,
first of all a late Happy New Year! The osgSWIG team is happy to
announce osgSWIG/Py 0.9.1 for Python 2.6 which corresponds to the
OpenSceneGraph 2.6.1 version. There is an installer for Win32/Python
2.6 or if you feel funky you can try to compile osgSWIG/Py straight
from the source.
Please note that on Windows we can only support you with Python 2.6
- hence build with Visual Studio 2008. And another note, we decided
to only support stable releases, like 2.6.x or the upcoming 2.8.x
releases as the maintenance of the interface files becomes more
problematic. Be assured we are looking into some alternative ways to
generate them :)
For those users looking for an update of the version including
osgART (http://www.osgart.org) - please be patient, we are working
on the release of osgART 2.x and would like to keep things in sync -
there will be an update but not right now.
Please give the installer a spin - let us know of your problems in
the issue tracker.
Now, head over to http://code.google.com/p/osgswig/
Cheers,

For fixed such salary costs you need a regular income to pay it, which points to a subscriptions model. Support contracts would fit the requirement of regular income. I do have a few clients on professional support, but the number is high enough to employ other engineers, as it only a fraction of my yearly income - the bulk of my income is for bespoke development projects, but these don't directly fund general project admin but they effectively enable me volunteering me time on the unpaid aspect to project work. Such funding doesn't stretch to employing others. One could look to converting more commercial OSG users to pay for support, but we'd have to have a ten fold increase in the number of support contracts to pay for one engineer fulltime. Scaling funding is hard. What is more practical is leveraging a bit of time from a number of different osg users. This is effectively what we do right now, although not always as effectively and consistently as is desirable in terms of getting binaries and dependencies out regularly.

[osg-users] osgswig and wxPython
I've the beginnings of a simple light-fixture modeling component in wxPython and I am trying to use osgswig (2.2.0.1 version) as a base. I've started out by copying the file loading example which uses osgUtil.SceneView(). The code successfully loads the geometry of a lighting fixture (considering that this is done with readNodeFile that's not terribly surprising). Unfortunately, thereafter I can't maneuver the view with the mouse. Sometimes, I can't even find the fixture model. I suspect I'm doing something dumb.

Re: [osg-users] Packaging granularity + platform specific scripts
The remaining problem is: What about Windows? Even the package term doesn't exist! And I currently don't have much ideas (sorry). What *nix calls packages, Windows calls installers. Since XP at least--I think since Windows 2000--there has been some kind of package management on Windows. Package data is kept in the registry. I have a book on writing Windows installers in my office, but I won't be able to consult it until the term ends, and I'm really hoping there's someone on the list who already knows the material better than I, because I'm not going to know very much about it for a while, Randolph On Nov 26, 2008, at 2:23 PM, Sukender wrote: Hi Robert, I'm not an expert in linux packages, but what you described is fine for me: - Core OSG + Animation + Widgets - Images + freetype - Sound - Introspection/Wrappers - Other I think that less than 6-7 packages should be ok.

In particular I want feedback from potential platform maintainers that are up for helping build binaries for each platform. My ideal is for use to use the same granularity and naming of packing for all platforms. One constraint already placed out there is fitting in with existing packaging conventions. For instance if I check Kubuntu 8.10 I get libopenscenegraph7 (OSG-2.4) and libopenscenegraph-dev, openscenegaph, libosgal and libosgcal packages. Without installing these I can't see exactly what parts of the OSG come along with it. I believe a good package layout would be in step with the major dependencies that that bring with it. For instance the core OSG package could just depend upon C++, OpenGL, GLU, X11/Win32/Carbon. Without freetype and the image plugins it isn't that useful though unless you have a very tightly focused vis-sim app. Next set of package(s) would be the main imagery ones like tiff/gif/jpeg/png, or would these be rolled into the base package? Further out still then you have GDAL, COLLADA. Then we have the specialist plugins that depend upon Inventor, libxul/gecko, libVNCServ, Svgr/Cairo, Cairo/Popper, OpenVRML (and an out of date version at that...). Further down the line I would like to see an osgAudio library integrated into the core OSG, this may well directly depend upon OpenGL, and as such would this make OpenAL a core dependency, or just have it made as a none core dependency with a separate package for it. Orthogonal to these dependency based packages, I am think that the osgIntrospection and osgWrappers are probably something that could be its own package, as the osgWrappers are extremely large, larger than the core libraries themselves, so placing them in a separate package that only users that need them would pull in. My expectation is that we probably won't be able to roll out packages for all the different possible major dependencies, and in these cases users will just have to grab the OSG sources and download there own. I don't have a problem with this - as long as we have base packages that most users can grab and use in their applications I'm happy. We might want to make it possible for users to match these extra modules with the standard distributed packages that they plan to build upon, although this might just be more awkward than it's worth... As I mentioned earlier I would like to get a scheme together for 2.8, and get this rolled out soon, I would have like this month, but someone seems to have stole all the days of November so we don't have time left to make 2.8 this month, but we absolutely should get 2.8 out the door before the Christmas break. I'd all like to get next years round of linux distro's using 2.8 rather than out of date versions of the OSG (Kubuntu 8.10 has OSG-2.4 which is stable release behind us). So please engage on this topic. Tell me what packages you'd like to see. Also if you can help out making the packages, what elements to the OSG could be done to make your life easier?

Re: [osg-users] Packaging granularity + platform specific scripts
Different platforms use different levels of granularity. Mac OS bundles libraries into frameworks, which can themselves be placed in application bundles, or installed for systemwide use. This is a very coarse level of granularity. I think OSG would probably best fits what Apple calls an umbrella framework--a framework which contains frameworks. I'm not too clear--yet, anyhow--on how Macs deal with framework dependencies on other frameworks and libraries; I have the impression it's not automatic but instead handled ad-hoc by the installer script or by the app. Randolph On Nov 25, 2008, at 7:09 AM, Robert Osfield wrote: Right now we have the OSG itself has an OpenSceneGraph/packaging/pkconfig directory, and this contains an openthreads.pc and openscenegraph.pc files. Looking at these files they don't lists all the OSG dependencies, and they obviously don't break it down like I'm advocating above. I'm also aware that on debain there are plenty of other configuration files associated with the debian packaging. What I feel would be appropriate would for us to centralise this, and make full use of the existing packing directory, full it out as required. I also feel the granularity needs to be addressed - but what sets of packaging and naming would be appropriate? ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

results to the issue there, but the latest result is no result--I
don't think anything changed.
On a different subject, I've made some small changes to FindOSG.cmake
which make the osgswig build happier with linking to OSG library files
in an Xcode build. I'm not sure of the merits of these, so I'm
putting them out here--what do people who know the Mac environment
better than me think?

[osg-users] osgswig confusion
I've been fiddling with osgswig on Mac OS (Leopard, 10.5.5), and I ran into a version of the vector mixin problem. After some fuddling around, I came up with a patch for it (see http://code.google.com/p/osgswig/issues/detail?id=18 ) and the python bindings built. But now, when I try to use them, I see: $ python simpleosg.py Traceback (most recent call last): File simpleosg.py, line 9, in module import osgDB, osgViewer File /Library/Frameworks/Python.framework/Versions/2.5/lib/ python2.5/site-packages/osgswig-0.9.0/osgDB.py, line 316, in module class AuthenticationDetails(osg.Referenced): NameError: name 'osg' is not defined There seem to be some imports missing from the built code.
