Re: [osg-users] Compressed texture
HI Yefei, The OSG has support for removing duplicate state on an already loaded scene graph, but at present there isn't any support in the .ive format for pooling imagery/texture between sets of .ive files. The later feature would be very useful though... so please feel free to dive in and implement it :-) The next question is... how would one go about it. Perhaps a custom state pool Node that does nothing more than hold a map of names/ID to StateAttribute. Then you could save this node out to it's own .ive file, then each of the other .ive files could include this StatePool node as an external file reference. Then use the Registry cache to make sure that each of the separate .ive then reuse the same StatePool. Finally the .ive plugin would need to have some kinda of ID system to pull the apprpriate attribute from the current StatePool(s). Robert.

Reading through the source code, it seems to indicate that the internal texture format is preserved by the dds loader as compressed texture, and passed on to the osg core. So I assume it works. I have thought of converting the flt files that uses compressed textures to ive files with built-in texture and with one of the compressed texture options. But in my set up I use multiple flt files that share textures, and I'm not sure if with built-in textures in ive files, I will have multiple instances of the same texture loaded into memory, so instead of one uncompressed texture in memory, I may end up with 20 compressed texture of identical content in memory. Is this what's going to happen with ive files with built-in textures?

Re: [osg-users] Import Large Meshes
Hi Brian, I'm afraid VirtualPlanetBuilder is based around processing heightfiels + imagery, not irregular polygonal meshes so won't be of any help. The osgUtil::Simplifier might be able to help though, although you'll probably need to break up the model into chunks first. One thing it would be worth doing is when loading you models is to disable the tri-stripping of the models. Robert.

Re: [osg-users] DatabasePager Stats
Hi Mike, 2009/3/31 michael.schm...@l-3com.com I apologize in advance if this has already been answered, but I didn’t find anything. One of the stats views shows “DatabasePager time to merge new tiles”. What is the meaning of the different values, especially the “requests” value? What would cause it to spike on a flt file? Each external file reference that has to get paged in will be a single file request. The external file requests are instigated by either PagedLOD or ProxyNode, with .flt it'll have to be the ProxyNode as it doesn't have support for PagedLOD. The OpenFlight plugin uses ProxyNode for external file references. You can pass different options into the OpenFlight plugin to get it to loaded the the external file references up front.

[osg-users] Object oriented coding
Hi, I have done some small test projects for fun in OSG, without really learning it correctly. Now I have a very general question: How do I structure my code to make it more object oriented together with OSG? Let's say I want to visualise an airport with planes coming and leaving. I would like to write this program in an object oriented manner, where the airport has a number of planes, where each plane has a number of parts etc. A plane should of course have properties such speed and engine thrust. Same thing goes for parts of a plane. For instance a wing should have a number that represents the drag, and also a number for its weight. It should also have visual information (shape, position, material etc). How do I combine this visual information with non-visual information in an object oriented manner? I guess visual information should go into the scene graph where as the rest does not. Yet, I want all the information about the wing to go into the same C++ wing object. Is there any good example showing how to manage this? I would love to see simple code examples showing these principles as they are easier to understand.

Re: [osg-users] problem using overlay node
Hi Rahul and osg-users,
I've recently tried to use overlaynode with blending and i didn't achieve to
make it work...
Is there someone who has a simple sample file with data to show the
community how overlay node works when it comes to set some blending between
overlay and overlay subgraph ??
Kind regards,
2008/8/7 Rahul Jain rah...@darshan3d.com
Hi all,
I am trying to overlay a shape file on a terrain using overlay node. But
the two textures are not blending, instead the overlay texture has replaced
the terrain texture. I am attaching the final rendered image for you to
ponder upon. I am using the code of osgsimulation example which goes like
this for my case.
// Get coordinate system node
osg::CoordinateSystemNode* csn =
dynamic_castosg::CoordinateSystemNode*(terrain.get());
// Set overlay technique
osgSim::OverlayNode::OverlayTechnique technique =
osgSim::OverlayNode::OBJECT_DEPENDENT_WITH_ORTHOGRAPHIC_OVERLAY;
// Create overlay node
osgSim::OverlayNode* overlayNode = new osgSim::OverlayNode(technique);
// Set blending parameters
overlayNode-getOrCreateStateSet()-setRenderingHint(osg::StateSet::TRANSPARENT_BIN);
overlayNode-getOrCreateStateSet()-setMode(GL_BLEND,
osg::StateAttribute::ON);
overlayNode-getOrCreateStateSet()-setTextureAttribute(1, new
osg::TexEnv(osg::TexEnv::BLEND));
overlayNode-setOverlaySubgraph(shapefile.get());
overlayNode-setOverlayTextureSizeHint(1024);
overlayNode-setOverlayTextureUnit(1);
// Set clear color
overlayNode-setOverlayClearColor(osg::Vec4(0.0, 0.0, 0.0, 0.0));
// insert the OverlayNode between the coordinate system node and its
children.
for(unsigned int i=0; icsn-getNumChildren(); ++i)
{
overlayNode-addChild( csn-getChild(i) );
}
csn-removeChildren(0, csn-getNumChildren());
csn-addChild(overlayNode);
// Set scene data
viewer.setSceneData(csn);

Re: [osg-users] Object oriented coding
Hi Tomas, This is a software design question, not really an OpenSceneGraph one. I'd recommend reading articles/books on game/object oriented design. The design of your classes will depend on your application requirements, taking into account money/time/etc. constraints. I'd recommend that your design abstract out rendering such that your OSG code is in separate rendering components. We do this in our visualization applications to allow us to switch renderers. We do this using a component based object management design (see http://cowboyprogramming.com/2007/01/05/evolve-your-heirachy/) and it has worked out really well.

Re: [osg-users] Object oriented coding
Thanks for the reply. That's an interesting article. It does make sense when thinking about it, although the object oriented stucture is deeply rooted in many programmers' heads (mine included) :) Anyway, I think my question applies to objects and components alike... How does adding data to the scene graph (and drawing it) fit in to objects and components? Staying with object thinking for a while, do people generally create an AddToSceneGraph() member function for sub objects that are to be rendered? With this approach I suppose there is no Draw() member function in sub objects, as this does not go along with drawing the entire scene graph once every frame. Am I right? I know I should probably read some good literature on this, but for now I just want to test the concept and get a not-in-depth general understanding. Is there any small example out there using an object oriented approach together with real OSG code? I know this must sound like a real newbie question, but when it comes to games and scene graphs I'm still a newbie :) By the way, is there a way for me to not publish name and email in this forum?

Re: [osg-users] Compressed texture
Hi, Robert, Thanks for your reply. Yes, I agree it will take quite some effort and possibly format change to implement texture sharing between ive files with built-in textures. That's why I would like a quicker way out:) -- using ive files without built-in texture but refer to compressed texture in dds format. Is my assumption correct that compressed texture in dds format remains compressed when loaded into memory and passed on to the osg core and GL layer without being decompressed, as opposed to say jpeg images which are decompressed during loading and then passed on to osg core in uncompressed bitmap format?

The later feature would be very useful though... so please feel free to dive in and implement it :-) The next question is... how would one go about it. Perhaps a custom state pool Node that does nothing more than hold a map of names/ID to StateAttribute. Then you could save this node out to it's own .ive file, then each of the other .ive files could include this StatePool node as an external file reference. Then use the Registry cache to make sure that each of the separate .ive then reuse the same StatePool. Finally the .ive plugin would need to have some kinda of ID system to pull the apprpriate attribute from the current StatePool(s).

[osg-users] ObjectType querry...
Hi All, Can anyone tell me whether there is a way (call) in OSG to say what type of object a plugin will produce ? i.e. if I have a file A.jpg and I call osgDB::Registry::instance()-getReaderWriterForExtension passing in the file extension, I get the readerwriter. What I would like to know is what ObjectType that readerwrite would return. The reason for the question is I'm updating the ReaderWriterZip plugin to handle in-memory zip extraction, and I want to be able to give it a zip file that contains many files of varying format. Rippling through the zip file I can get the individual files, and their content, and unzip them in memory, but the issue I have is that I don't really want to have a big If statement in the plugin to look at the known file extensions and to say whether I should be calling ReadNode or ReadImage. I would like to be able to enquire the type of Object that the reader would produce, and then have a simple switch statement like the Curl plugin. One route I thought of would be to add to extend each plugin to have a function based that returns the type of object, and I guess this would be fairly straight forward, but before delving in, I just wanted to check if there is a method already available. Many thanks for any help. Neil. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Object oriented coding
Tomas, Check out the osgcatch example.

That's an interesting article. It does make sense when thinking about it, although the object oriented stucture is deeply rooted in many programmers' heads (mine included) :) Anyway, I think my question applies to objects and components alike... How does adding data to the scene graph (and drawing it) fit in to objects and components? Staying with object thinking for a while, do people generally create an AddToSceneGraph() member function for sub objects that are to be rendered? With this approach I suppose there is no Draw() member function in sub objects, as this does not go along with drawing the entire scene graph once every frame. Am I right? I know I should probably read some good literature on this, but for now I just want to test the concept and get a not-in-depth general understanding. Is there any small example out there using an object oriented approach together with real OSG code? I know this must sound like a real newbie question, but when it comes to games and scene graphs I'm still a newbie :) By the way, is there a way for me to not publish name and email in this forum?

Re: [osg-users] Compressed texture
As I' m also interested in texture compression my question is: when using .osg files or ive files without texture inside (those obtained by osgconv -O noTexturesInIVEFile useOriginalExternalReferences foo.osg soo.ive) if there is a chain of pagedlod files that refer to the same texture (for example the same material texture is used for different files at different lods) does it get readed or loaded in txture memory several times? I though it does not happen... but willing to be sure. Instead, if it is embedded in ive, it is replicated. Am I wrong? Another question: could be feasible to store jpeg as S3TC_DXT* instead of uncompressed? I know it is not happening now... would it be hard to implement? are there technical limitations? it seem to me that other web enabled sw like Google Earth are transmitting jpeg texture I experimented once trying to call the same compression code in osgconv inside the jpeg plugin after the read... but the code got unstable and slow.

[osg-users] testing for multisampling capability
I'm trying to enable 4x multisampling in my application. When running on systems with decent video drivers this is a simple matter of setting traits-sampleBuffers when I create the graphics window and it just works. Unfortunately in testing I've run into a system with an integrated Intel graphics driver that appears to not support multisampling -- I get pixel format error when I try to create the graphics context. I need to fall back and disable multisampling in this case, but presently in our application this requires that the user edit an external xml configuration file. Ideally it should be able to probe the driver features to determine if multisampling is available. What is the best way to do this in Open Scene Graph? I tried creating the graphics window, testing for failure, and if so disabling multisampling and trying again. Unfortunately, in testing this approach on a different system I ran into a problem -- it seems that once you've requested a graphics context with one multisampling setting, you can't ask for a different setting? I created a multisample graphics context, forced the initialization to be considered to fail, deleted the context, then asked for a non-multisample context (with all the same settings), then reports an invalid pixel format on trying to change the multisample settings. It's very weird. I'm sort of out in the weeds, here. It would be nice if there was some way to use OSG to ask the driver what it supports rather than having to play guessing games with graphics context initialization. Does anyone have any ideas?

Re: [osg-users] Node to Geode
If the top level node isn't a Geode (which it isn't except for the very simplest of scene graphs), you'll need to walk the scene graph to find the Geode of interest. In OSG this is done with a NodeVisitor. I suggest you get the OSG Quick Start Guide and read through it (search at www.lulu.com).

Re: [osg-users] default coordinate system and camera - newbie
The CameraManipulator (like TrackballManipulator, for example) determines the default orientation. You can change this default by setting the up vector in the TrackballManipulator. By default, the TrackballManipulator uses positive Z up, so if your code is getting positive Y up, either you have a bug or you are not using the TrackballManipulator or you have changed its default. The default view position is also determined by the CameraManipulator. The TrackballManipulator, for example, has a home position that you can set. By default, it considers the scene bounding volume and tries to position the view so that the entire scene fits within a 50 degree FOV (I think it's 50, not sure).

the key press event.
I already have that implemented in OpenGL program where i can roll, pitch
yaw and slide with user key press event.
I want to map that in the scene graph system.
I have the following information predefined
*n* = eye - look;
*u* = *up* * *n*;
*v* = *n* * *u*;
To move the camera in an ineractive way i have to have the access to there
values .
there is a function in the Camera Class called getViewMatrix() , i hope that
it is one to access these values.
Any more reference would be of great help.

MAK has been involved in visual simulation for over 16 years now, and over the years, we've talked to a lot of people who have expressed frustration about the state of the 3D visualization market: Commercial image generators (IGs) always have great features out of the box, but they are usually closed systems - often tied to a vendor’s content-generation toolchain, and often without a toolkit API for user customization or extension. On the other end of the spectrum are scene graph toolkits like OSG - which offer unlimited flexibility, but require lots of application development and content integration work just to get to the point where you can really start adding your project-specific capabilities. What's really been missing is a product that provides full-featured out-of-the-box applications, *and* the ability to extend, customize or embed any of that application-level functionality into custom applications. Missing...until now! What we are offering with VR-Vantage is the ability to turbo-charge your OSG-based development project. A typical OSG user (particularly in the visual simulation domain) spends lots of money incorporating content, and lots of software development time implementing or integrating application-level functionality, such as: • Game-like or virtual-globe-like navigation interfaces • Human character animation • Real-time trees and vegetation • Graphical User Interface • A sky/lighting/environment model • An entity management layer • Full-featured DIS/HLA support • Top-quality 3D vehicle and cultural feature models • Run-time configuration system • Informational overlays about simulated objects • Fully-integrated Distributed Rendering for multi-channel displays • Streaming terrain elevation and imagery from web-mapping services • Heads-up-displays or interactive cockpit displays With VR-Vantage, we've built all of this content and capability into an inexpensive off-the-shelf product. We've licensed all the necessary 3rd-party technology, and spent the past two years integrating and developing a powerful application-level OSG-based toolkit - so that you don't have to do it yourself! The VR-Vantage applications, which include the MAK Stealth viewer, and a new desktop IG called Vantage IG, already incorporate all of the following as standard features: IDV's SpeedTree vegetation, BDI's DI-Guy human characters, DiSTI's GL Studio cockpit displays, SunDog Software's SilverLining clouds and environment, Pelican Mapping's osgEarth streaming elevation and imagery, a customizable Qt-based GUI, native HLA/DIS support based on MAK's own VR-Link toolkit, multi-channel distributed rendering, and a library of high-quality 3D models from companies like Simthetiq and RealDB. And no 3rd-party run-time licenses are required to use any of these capabilities! But you still retain the same level of extensibility you’d have with OpenSceneGraph. VR-Vantage offers a higher-level API above the scene graph, to provide as much power as possible. But you always have direct access to the OSG layer as well, so that you can easily incorporate existing OSG nodekits and file loaders, and can continue working with the API you're comfortable with. Plus, you’ll have MAK to support you, so you can stay focused on your project-specific tasks. Start with the VR-Vantage Toolkit, and you can immediately begin working on your application-specific functionality, giving you a leg up on your competition, and allowing you to execute your projects with much lower risk. VR-Vantage was previewed at I/ITSEC 2008, and version 1.0 shipped today, March 31, 2009. For more information about VR-Vantage, please see http:\\ www.VR-Vantage.com, or visit http:\\www.mak.com.

Re: [osg-users] Return of the DepthPartitionNode
Hi Ravi, Last week I asked something about DPN with no response, but maybe you are the man to refer to, so here I quote myself again: Hi, Several days ago I asked about depthpartition, but now I've a more complex situation that I want to figure out. It begins with depth partition but ends up with how cameras do work. I tried to combine the depth partition with the osgdistortion code. The idea was to try to put cameras above and under the depth partition node and see the effect. I have DPN node, Scene node (which is a group for the scene) and Distortion node (which is two pass cameras, one renders to RTT and the second use the texture, distort it and renders to screen). I got pretty much confused. First I tried to put the DPN above the distorted scene (that means DPN-DISTORTION-SCENE). It did not render correctly. Only the closer depth interval of the two intervals was rendered. So I tried to put the DPN above the scene and under the distortion node. (DISTORTION-DPN-SCENE). Then NOTHING was rendered. I tried to change the DPN camera render order to PRE_RENDER. Again, nothing. Then when I changed it to NESTED_RENDER, all was rendered but not in the correct order. So I tried to change the RenderOrderNUM of the cameras of the DPN to ensure that the far intervals will be rendered first (lower RenderOrderNUM) but it did not help... I tried to reverse the RenderNUM (higher for farther intervals) with no difference. So it brings up questions: Why does the RenderOrderNUM didn't have effect? Where is the correct place to put the DPN? Why when the DPN was above the distortion node the closer interval was rendered, and when there is no DPN at all, the farther interval is rendered? Why when the cameras of the DPN were not NESTED_RENDER nothing was rendered? Would it be more correct to add Slave cameras to the scene instead of using these cameras only in the culling traverse? I guess that's it for now...
