If you can't find a fix please raise the topic again once I've got the OpenGL ES 2.0 port done as I'll then have a bit of time to put into VPB.

[osg-users] Solved Re: VPB: How to get and convert model coordinates?
Hi:
The solution was in the same example code I am using (osgpick), but
Glenn Waldron from osggis told me the hint.
Quotiong: {
1) Find the osg::CoordinateSystemNode (CSN) atop your VPB database scene graph;
2) Get the EllipsoidModel from the CSN
3) call EllipsoidModel::convertXYZToLatLongHeight().
}
Tha's exactly what osgpick does to get the current elevation.

In VPB the vector (build and forest outlines imported from shape files) support is limited to databases build that use polygonal meshes rather than osgTerrain::TerrainTile. VPB now defaults to generating databases with osgTerrain::TerrainTile's as they are more compact and more flexible as they allow runtime decimation of data as well as terrain modifications, but it doesn't yet have support for handling vector data. To use the polygonal build you'll need to use --polygonal. I would like to see support added to osgTerrain::TerrainTile to allow us to provide polygonal outlines and fixed points of interest that the tesselation will honour, once this is in place we'll be able to get the shapefile support in VPB rolled out to all combinations.

PERTHSHIRE, Scotland - 12th February 2009 - OpenSceneGraph Professional Services announces the release of OpenSceneGraph 2.8, the industry's leading open-source scene graph technology, designed to accelerate application development and improve 3D graphics performance. OpenSceneGraph 2.8 written entirely in Standard C++ and built upon OpenGL, offers developers working in the visual simulation, game development, virtual reality, scientific visualization and modeling markets - a real-time visualization tool which eclipses commercial scene graph toolkits in functionality, stability and performance. OpenSceneGraph 2.8 runs on all Microsoft Windows platforms, Apple OS/X, GNU/Linux, IRIX, Solaris, HP-UX, AIX and FreeBSD operating systems. Open-source development delivers industry-leading features and performance ¶ The OpenSceneGraph 2.8 release is the culmination of 10 years of work by the lead developers and the open-source community that has grown up around the project. The real-time graphics industry and academia embraced it from the very beginning, deploying it in real-world applications, and actively participating in its development, testing and refinement. The end result is a high-quality library with a feature set relevant to application developers' needs. Updates include: ¶ * New osgVolume library for volume rendering, with support for: o High quality GPU based Ray tracing o Transfer functions o Per pixel lighting o Iso surface rendering o Maximum Intensity Projection rendering o Non-power-of-two 3D textures, and 3D texture compression o DICOM loading for reading dicom medical data * New osgAnimation library for character and scene animation. * New plugin for reading Biovision hierarchical files (.BVH) to generate character motion animations. * New osgShadow support for Light Space Perspective Shadow Maps. * Three new scene graph widgets for placing traditional 2D capability into fully interactive 3D scenes: o PDF widget (based on libPoppler) o VNC client widget (based on libVNCServer) o Internet browser client widget (based on Gecko/UBrowser) * New plugins for loading Half-Life 2 maps and models. * New plugin for loaded EXR, high dynamic range imagery * Improvements to DatabasePager, tailored for low latency paging. * Improved run-time stats collection and on screen reporting. * Performance improvements through optimization of matrix operations. * Support for the OpenGL draw instanced extension. * Support for zlib compressed native .ive and .gz files * Improvements to COLLADA support. * Build reporting using CDash * New packaging support using CPack * A wide range of build and bug fixes Downloads and Licensing ¶ OpenSceneGraph is open-source, so full source code is provided, and can be copied, modified and used free of charge for commercial and non-commercial use.

Re: [osg-users] LOD: discrete or continuous?
Hi Robert, ChunkLOD is not CLOD, it's a static paged database, which really is far less use than what the OSG provides natively with its DatabasePager with VirtualPlanetBuilder generating the databases. Exactly, your current implementation is much better than the old OSG ready ones you can find at VTP. As for CLOD implementations, most don't scale well, don't handle geocentric databases, and most don't perform particular well in comparison to static paged databases. Personally I think CLOD is not as useful as it once was, the balance between GPU power and bandwidth/CPU power has drastically altered in the last five years, what made sense five years ago really doesn't these days. Ok. But by all means go spend time on stuff that isn't really useful... I rather would like to contribute vpb with useful stuff. IMHO there is yet room for improvement, and I would be more than happy to contribute.

[osg-users] How to pass a fixed possition to a vertex shader?
Hi Umit, You have used same texture unit for 2 texture so your last initilazed texture on unit 1 active. I mean, EarthCloudGloss active on unit 1. so you should texture EarthCloudGloss to the unit 2. That's what I thought but it was not working. There was a silly mistake in my osg code, I was reusing texture2 instead of texture3 in the last image assignment (as you can see in my first message). That's fixed now. My problem is tha I have a fixed possition in world coordinates (LightPosition) as a Uniform parameter. At the time of passing it to the vertex shader, apparently it is seen as fixed in screen coordinates. If I move the view, the scene moves but not the effect of the shader. How should I convert the vertex coordinate? I know this is maybe a faq but as I told, it's my first shader experiment, and I can't make it work. I will highly appreciate any help.

[osg-users] Shaders and multitextures
Hello:
I built a terrain with two textures to test osgmultitexturecontrol. It
fade between both textures. Now, for the effect I am looking for in
another scene, the use of shaders would be convenient. I want to
reproduce in osg the example from chapter 10.3 of the orange book
(Multitexturing Example). The shaders are available in the book's site
http://3dshaders.com/home/index.php?page=shop.product_detailsflypage=shop.flypageproduct_id=12category_id=1manufacturer_id=0option=com_virtuemartItemid=3
The reason this shader is suitable is that it uses a daytime or a
nightime image of Earth, and uses on the sphere the corresponding
texture to the position of the sun. Actually I want to control not two
but four areas on the sphere (also the polar circles). Perhaps this
can be done with subtextures, but the shaders seems to be good for the
job.
The problem, as usual, is the lack of documentation. Currently I am
able to texture the daytime image and the clouds cover, but not the
nightime image. What is the purpouse of the second parameter (int) of
the Uniform constructor. A reference for the texture unit or something
else?
osg::Uniform* terrainTextureSampler = new osg::Uniform(EarthDay, 0);
This is the first time I use shaders with osg, so please be patient. I
am pasting the shaders and texture functions. I will appreciate any
hint.
Best regards,
-- A.

The osgTerrain::TerrainTile class supports multiple osgTerrain::Layer(s) so you can attach multiple images as multiple layers and these in turn map to multiple texture units. You can then manage the blending between them using osgFX::MultiTextureControl node decorating the whole terrain. The osgmultitexturecontrol example shows this in action. Robert.

Re: [osg-users] vpb: Spherical terrains?
Hi Robert: It's not my intention to jump into a new scheme, but using current vpb algorithms, it should be possible to do a few adaptations to better deal with spherical terrains, that's all. Ok I will wait until there is a minimal set of documents about vpb at the wiki, next month. Regards, -- A.

Using a substantially different terrain division algorithm would require a major rewrite of VirtualPlanetBuilder, and it's not just a little bit of code that is straight forward to learn and easy to tinker with. The papers you might come across we just scratch the surfaces on the actual details required for implementation of highly scalable terrain generation. VPB can handle terrabytes of source and output data, there's only a few pieces software in the world that currently does this for terrain, and VPB is the only open sourced one I'm aware of. Handling terrabytes of moziaced multi-resolution data is the hard part that few bits of software handle. So... jumping to a new scheme is not easy at all, and the papers won't help you, and rather than look for grand all encompassing solutions look for smaller solutions, and there are some such as changing the sample dimensions on polar tiles that will actually solve most of the problem with massive changes or long learning curves.

[osg-users] vpb: Spherical terrains?
Hello: As recommended in this forum, I installed both osg and vpb from svn and I was able to reproduce the example with the Punget terrain. Now I want to try it with planets, starting with the moon. I started trying with these parameters --geocentric --spherical --radius-equator 1735000 but I get this error: ERROR 1: Unable to compute a transformation between pixel/line and georeferenced coordinates for moon_heigth.tif. There is no affine transformation and no GCPs. I assume I could add that transformation in a world file or creating a geotiff file, but I am not sure how to do that. I also assume that the bluemarble options only works at Earth scale, as in this example: http://www.andesengineering.com/BlueMarbleViewer/ Sorry if these are faqs, I am a newvbie and there is not much documentation about this subject. I will appreciate any advice. Regards, -- Alejandro Sierra ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
