Re: [osg-users] [vpb] Any way to build terrain complex with DEM data and then add different textures after?

This works great when I have relatively low resolution. I am now running into scenarios where I am using 1 meter lidar elevation data and want the maximum number of levels. This takes hours to generate, but I may be looking at the same area over and over. However, the texture that I wrap onto that same are will be changing. Do I need to run osgdem for each texture? As far as I can see in the documentation there isn't any way to add texture to an existing osgdem-generated terrain complex; am I wrong? I know that for each level, osgdem is breaking up the original texture and doing level of detail wrappings for it, so maybe it is impossible. I may end up digging into the source code for osgdem to see what can be done but wanted to pose this question to the forum to see if anyone has any ideas about whether this can be done already or how feasible it is to do this by changing the existing source code. Thanks! One word: osgEarth. http://osgearth.org/ It can drape new imagery onto VPB-built terrain models, or can just build the terrain models on the fly with whatever imagery you want.

I have read that SDL only allows one audio channel, so I think I have to start using something else. I want also to play other audio files (mp3, ogg, wav, whatever). So, which is the best option right now? I have read about osgAL and openAL. I don’t know which one is better with the version I am using (OSG 3.0.1) or if there is a better solution to these two. Another thing to consider is that I would like to work with LGPL (or similar) licenses if possible. I think those libraries are LGPL, but as they depend on additional libraries I am not sure if I can use them as LGPL or not. 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.

[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.

On 12/14/2011 7:26 AM, Jesper D. Thomsen wrote: I have a question regarding exporting to SVG from OpenSceneGraph. In our software product we use OpenSceneGraph for both a model view window and for a charting component. So far we have exported images from the charting component as bitmap images (by just rendering them to an offscreen pixelbuffer in the required resolution). We have however had some requests for exports from our charting component in a vector format compatible with the Microsoft Office software package (which pretty much means EMF files). Since EMF is very Microsoft-specific, I was thinking of using SVG as an intermediate format, and then using some converter package to create the EMF output. I saw SVG mentioned on the OSG mailing list earlier, but my question is whether there is any way to render to vector SVG from OpenSceneGraph (I kind of expect a hard “no” here)? The graph contents can be both 2D and 3D graphs and the 3D graphs can contain shaded, but non-textured, 3D-surfaces. 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_3dpage=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.

For example if I know that my object's internal coordinate system specifies that positive x is north and positive y is west and I place that object on an arbitrary WGS84, geocentric terrain, how will I know how to rotate the object to line up the north orientation? 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, 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. But it is up to you to design the scene graph structure to store, and utilize this data. I was considering to store collision geometry there as well, but this is not the strict requirement. You could store this geometry there too, masked so that it does not render but can be accessed during intersection testing.

I like using FBOs as they are kind of the newer cleaner way of doing things, especially if the work stays on GPU. I don't know if FBO GPU-CPU read speed is any faster than PBuffer, I suspect they'd be the same. Having many viewers means that you have a copy of all scene elements per agent. I cannot share the same scene graph with multiple viewers (i.e. give each viewer a pointer to the same graph)? They have to be separate copies? You can share the graph, but each viewer will create its own graphics context. You can't share OpenGL objects between them then. I'm not sure if you can share contexts between viewers. I know you can share them between views in a composite viewer, or between cameras in the scene. As JP says, you can share the graph(s) or portions of them. Ok, how do I control each camera? Can I put on the scenegraph under a transform node so that I can use a callback function to control each camera motion?

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.

I really don't know how well this would work out having not tried to migrate services other than mailman across to them. If we do have to move existing services across quickly this might be strong contender. I've used Dreamhost for a long time (2002) and they're pretty good. 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. We'll need the engineers to help our with coordinating and undertaking this work. Once we've got a basic plan and the people in place we start migrating bit by bit. 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.

Of course that has been touted as very inefficient and I agree with that. I had looked at inheriting from osg::Drawable::UpdateCallback but figure that I'd have to make the varience DYNAMIC anyhow so it wouldn't matter. So, my question is, would there be a better way to make this thread safe other than setting the root node to DYNAMIC to avoid crashing when adding another node to the root? Well, it's somewhat inefficient if you run the viewer multithreaded, but the way that it's inefficient is kind of irrelevant in your situation since it seems like you'll have to incur that inefficiency no matter what because your graph is potentially dynamic on every frame. Basically, in my mind, no trick will ever avoid the fact that you have to wait for rendering to completely finish before modifying the graph. There might be some devious trick that could allow otherwise (maybe two copies of the graph and you stagger the accesses and the visibility of them?) but premature optimization is the root of lots of bad things. Just do it the proper way now, and see if the performance is really a problem or not, and deal with it then if it is. And just in case you're wondering, I'm replacing the viewer first because it crashes the most of all of the other systems. Wise choice.

I think (I may be wrong) that placement this way will not be successful for UTM-based terrain. While I think PROJ4 can be convinced to reproject your UTM for you, it's probably easier to use GIS tools to reproject it yourself up front and then feed that to VPB.

The linking error is the same regardless of the GDAL dependency that I am using, so I think that the problem lies in the Visual Studio bug pointed out by Mattias.
