Basically, you need to have a reference in your main code to some data or code object in the desired plugin code, so the linker doesn't optimize out the plugin during linking. The USE_OSGPLUGIN() macro does this for you, but it probably uses some magic that isn't right for the osgText plugin. I'd look at the macro and see what it's doing, and then go look at the text plugin and see what you have to do manually (without the macro) to get approximately the same result. -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Digital Imaging.

These changes involve modifying all external references in the loaded graph to each have a .modifyterrain suffix, to ensure the modifyterrain pseudoloader is always in control of the final say when new branches are loaded.

First question would be -- what exactly do you define "Night Vision Effect" as? Infrared? Image intensifier? IR requires emissive properties on your models and a shader to utilize them.

My DH site is not high-traffic, but they've been fairly reliable. More reliable than Valencia (though I don't know the reasons for Valencia's downtime). If you go with Git (and there's a lot of discussion about Git vs Hg -- I've used Hg more recently), I'd just use GitHub. They seem to have this stuff figured out. No sense badly reinventing git hosting. I do NOT think OSG should run our own repository at this stage of the game, even if we _CAN_. > github also now have their own wiki, Gollum: > https://github.com/features/projects/wikis Chances are, it's adequate to do the things that TRAC's Wiki already does. In that case, it's good enough for me. I could also possibly offer to host the website myself. I have a colo box in a datacenter in Denver that hosts all my website and my OSG binary downloads. I don't pay for metered bandwidth, I only pay a flat monthly cost. My current server might be adequate for the task, but it might be pushing it too. I could figure out what it would cost for a newer machine (I'm budgeting a new rackmount server right now for another project) and the monthly monetary costs. I'd volunteer to install and keep the machine running if the community could assist with the hardware and recurring expense. I've done this for some other not-for-profit organizations I work with. The bandwidth is not guaranteed throughput, but we can pay for a 10Mb or 100Mb pipe and get quite a bit of utilization out of them. > Finally once we've decided upon hosts for our needs, and the > technologies that we migrate too we'll need to do the migration of our > present wiki and version control systems.

I'm probably not a good person to step forward for this. I especially know nothing about Wiki migrating, but even if we have to do that by hard, that's something non-sysadmin types could help with -- copying and reformatting a page and adding it to the new site.

[osg-users] osgEarth binary builds now available.
I just wanted to mention that we've now added osgEarth binary builds to the automated build system and now have them available in 32 and 64-bit flavors for Linux, Mac and Windows (VC++ 2008 and 2010). It was quite labor intensive to produce and maintain these, given the number of complex dependencies. Since we don't really ever get any donations to help run the build and distribution system, for the time being the osgEarth binaries (and future osg-ecosystem packages like osgWorks, osgAudio, osgOcean, etc) will be available for download by paid monthly subscription.

OpenGL really wants to focus only on a single thread, and you have to associate the context with a thread.

Well, generally the only paged formats OSG supports (excepting specialized formats like TerraPage) are its own .OSG/.IVE/.OSGT/.OSGB. .OSG and .IVE are deprecated. .OSGT is text and is slower, which leaves .OSGB as the primary contender. > The special requirement is that it should be possible to store non-standard > data like reflective color (not present in OpenGL), for instance as a "user > data". Well, given that this can be stored in the scene graph, it can be stored in the .OSGB format as well.

Ok, manually adding OPENGL_INCLUDE_DIR works. We've configured for egl, but at link time, it still appears to be referring to wgl functions.

Just try it. Make an object that points out the X Y and Z local axes graphically and stick it in using the EllispoidModel to orient it to the local ground's upvector and such. It will show you what the orientation ended up like, and then you can see what additional rotations might be needed to get what you expect.

Well, OSG can save to a few formats. Explore which ones support saving, and then if you can convert from one of those, through a modeling or conversion tool, into SVG or another 2D vector format. Alternately, if you used a 3D capture tool: http://www.planetpdf.com/creative/article.asp?ContentID=review_adobe_acrobat_3d&page=1 http://www.3d-test.com/interviews/OGLE_1.htm http://www.deep-shadows.com/hax/3DRipperDX.htm you might be able to convert from one of its formats to something you can use. -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Digital Imaging.

To do your own mailing list software, you typically need a static IP on a VPS (Virtual Private Server). Similarly, you can't run SVN on most shared instances, but a VPS can. Dreamhost, while inexpensive (I have an account with them to run some legacy sites) can be kind of skimpy on the memory and CPU. Large CMSes can have trouble running on the resources they provide.

[osg-users] OSG Texture1D and GL_UNSIGNED_SHORT
Just wanted to log a peculiar error I just dodged. Ive been using a 1D texture to do contour lines on terrain, a common technique. I had some trouble where it appeared that OSG was turning my GL_RGB UBYTE texture into GL_UNSIGNED_SHORT as it was uploading. I'm not sure why this was. I also tried adapting the very code from the osg osgtexture1D.cpp, create1DTextureStateToDecorate() and it seemed to do the same. I didn't debug it all the way into OSG, but I verified with gDebugger that glTexImage1D was being called with GL_UNSIGNED_SHORT for some reason. I switched to Texture2D, which seems to have no downside, and it works properly. I don't have a fix, I'm just recording my experience in case someone else runs into the same situation. Just switch to Texture2D with an n*1 texture unless you have a good reason not to. -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Digital Imaging. OpenGL.

As the creator of osgAudio, I can answer this. osgAudio is the literal and philosophical child of osgAL. We started osgAudio using the osgAL source, fixed a number of design and implementation issues, added compile-time selection of audio backend (openAL or FMOD) and polished it up. Thus, osgAudio. Even openAL's creator agrees that you should probably use osgAudio now, since it has newer fixes. OpenAL was LGPL, now proprietary (Creative Labs): http://en.wikipedia.org/wiki/OpenAL You'll have to interpret their licensing yourself. There is also OpenAL Soft: http://en.wikipedia.org/wiki/OpenAL#OpenAL_Soft "OpenAL Soft is an LGPL-licensed, cross-platform, software implementation" FMOD is proprietary but has a non-commercial license: http://en.wikipedia.org/wiki/FMOD "FMOD is available under multiple license schemes: FMOD Non-Commercial License, which allows software not intended for commercial distribution to use FMOD for free." You could fairly easily add support for other backends to osgAudio if you wished, but I'm not aware of too many other 3d spatial audio toolkits. -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Digital Imaging.

Have you tested the 3.0.1 binaries from AlphaPixel? http://openscenegraph.alphapixel.com/osg/downloads/free-openscenegraph-binary-downloads If they work, you know it's a build error compiling OSG on your end.

The "low" level examples just test openAL++/openAL, and have zero to do with OSG, so they're a good place to start. If that's not working, do you have other openAL tools you could test with?

You'll need to use a gridding tool to transform this into a regularly sampled surface. GDAL offers tools to do this. You can then query this grid directly, without using OSG, or if you need to visualize the terrain too, use VPB to build an OSG terrain database and use osgSim's Height Above Terrain tools to query it at various locations. -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Digital Imaging.

Yes, it's quite a poor test. I was actually only seeking to quantify the low end of the error, which is plainly visible as the thick band down in the <5 region. My code averages errors out down in this range, and throws errors out that are outside this range.
