[osg-users] Node Callback never called

[osg-users] [osgPlugins] statically linking osgPlugins for Android
I managed to get OSG compiled without issue for Android and incorporate it into my application. However, the models I would like to use are .3DS and I'm trying to get the 3ds plugin used. It was disabled in the build process, but was reenable without much issue. However, I don't know how to tie it into my application. Currently the Android toolchain builds OSG statically but when I enable debugging messages the code is still looking for .so plugins. This is also an issue for the texture files (osgdb_imageio.so). So I have two questions for possible solutions: 1) is there a way to make things that currently use plugins use statically linked code? Like an alternative registration to permanently register those plugins at init and make sure the code gets linked in? 2) if not, can anyone suggest how to make the plugins build as a .so and the core code to build as a static library (for Android).

Re: [osg-users] Problem with GUIEventAdapter mouse wheel event in Qt
Hi Michael, I'm rather cold on this topic as I'm no Qt expert but from a general perspective of how osgGA::EventQueue::mouseScroll() and osgGA::GUIEventAdapter work together one should expect the X,Y values return for a scroll event to be of the previous mouse x,y position and the mouse coordinates previous set up in EventQueue. The X,Y values won't be directly related to the mouse scroll event itself, the values for the scroll event are encoded in the GUIEventAdaopter::ScrollingMotion value. Robert.

I noticed that for SCROLL events, the x and y min/max were always -1 / +1, which caused GUIEventAdapter::getX/Ynormalized() to return the wrong values. So, I figured I would just use getX/Y() instead and use inverse viewport matrix to get the normalized device coordinates. But, then I noticed I was still getting inconsistent values for the Y coordinate. For a RELEASE event, the GUIEventAdapter has Y_INCREASING_DOWNWARDS for the y orientation, and getY() returns 0 in the top left corner of the window. For a SCROLL event, it has Y_INCREASING_UPWARDS and getY() returns 0 in the bott om left corner. Why are the two event types inconsistent? Is there some attribute I am forgetting to set somewhere?

Re: [osg-users] HUD disappeared
Hi wh? xiexin? Which human name would you like to be addressed as? There isn't any way we'll be able to pinpoint the problem you are seeing from just this code extract, there are simply too many unknowns about the rest of your application to pass judgement. The best I can do is provide a general comment. For on HUD compass I would recommend using a viewer slave Camera rather than a Camera in the main scene graph - this keeps the various components of the application behaviour nice and separate both conceptually and implementation wise. It might even solve the bug you are seeing as for all we know it might simply be that you are replacing the main scene graph with your new model and discarding the compass subgraph. Robert.

Re: [osg-users] Evaluation of OpenSceneGraph as scene graph library for embedded devices
Hi Frank, The OSG is capable of providing all these features on the desktop with fixed function pipe and embedded systems with the appropriate shaders. Performance wise the OSG will help you in your quest as it provides are wide range of features are written specifically for maximizing performance - i.e. culling, LOD's, state sorting, fast paths etc. Doing all what you require on embedded systems is not exceptional compared to what others are using the OSG for, and the OSG itself won't limit you. What will limit you is the hardware that you are deploying on and as this is a moving target and what exactly you'll have on screen on any time, and how well you build for scene graph are all variables that none of us can predict, so to yes or no would be simply irrational. The best we can advise is that OSG itself will help you in your quest as that's it's job. Any more or less than other API's? Again one can't really say yes or no, it depends upon what features the other API's support. I would however say that open source API's that are backed by active communities is a huge asset no matter what middle-ware you choose to use, and would say that on an evolving target like embedded systems this is far more critical as the community can pull together to keep track of new developments.

Each geometrical object is an extruded profile. It's first tessellated by osgUtil::Tessellator, and then I extrude the triangulated faces out a certain height. The result is two primitive sets, a GL_TRIANGLE_FAN from the tessellator and a bunch of GL_TRIANGLES that I manually create for the extrusion. I add these both as primitive sets with osg::DrawArrays. I doubt any of these geometries have more than 100 triangles -- most probably have less than a quarter of that. I'd like some advice regarding how I can improve rendering speed in this situation. I think that the two calls to DrawArrays per geometry is part of the problem. It might help if I could merge both parts in the geometry as one set of indexed triangles but I'm not really sure that would make a huge difference. Should I be using DrawArrays or DrawElements? Should I be using VBOs?

Hi Martin, On 21 July 2012 11:08, GeeKer Wang wwthu...@gmail.com wrote: In GLUT, there is a function glutGetWindow to get the current context ID. As far as I know, OSG get contextID for osg::RenderInfo in application. Are there other ways to get cureent GraphicContext ID in a thread? All rendering code in the OSG gets passed either a RenderInfo object which has the osg::State object for the current context or gets passed the osg::State object directly, the osg::State has a getContextID() method. For none rendering code there isn't a current context so there isn't a single ContextID that is appropriate, rather you have to decide which active GraphicsContext in the viewer is appropriate, so just get the windows from the viewer and then examine then for their osg::State object and ContextID. However, one must ask what your want the ContextID for, it's also nothing to do with any context ID that GLUT might want to manage, the osg::State::ContextID only has meaning with the OSG.

There isn't any way we'll be able to pinpoint the problem you are seeing from just this code extract, there are simply too many unknowns about the rest of your application to pass judgement. The best I can do is provide a general comment. For on HUD compass I would recommend using a viewer slave Camera rather than a Camera in the main scene graph - this keeps the various components of the application behaviour nice and separate both conceptually and implementation wise. It might even solve the bug you are seeing as for all we know it might simply be that you are replacing the main scene graph with your new model and discarding the compass subgraph. Robert.

Re: [osg-users] Question for understanding the way OSG internally works
Hi Werner, The type of problem you are working to solve is very domain specific so you'll need to write your custom shaders to support it, what you are looking requires relatively advanced knowledge of OpenGL and various associated rendering techniques. If the material is translucent then you will need to handle the issue of depth sorting or depth pealing to make sure that the correct blending can be achieved, if you require depth sorting then you'll need to segment up the cloth so it can be rendered from distant to near regions of the overall cloth. If the material is opaque then you want need to worry about depth sorting and could just render it as a single geometry. For the placement of the vertices I would use a vertex shader with the flat geometry as input as well as various other parameter per vertex which are required to compute the final position, normals and texture coordinates. You could also encode some of this informative via textures that are read in the vertex shader. A fragment shader then could be used to get the most appropriate lighting model to render your cloth.

Actually I'm using both kind of self written shaders already and the parallax displacement shader gives excellent results on yarn surface calculation. Also the problem is not just a displacement problem. Imagine some shine through curtains. The lower end has many bows. This means that the position of the vertexes has to be moved in 3D space. Through the holes of the curtain you even see the backside of some other part of the curtain. I know how to create a function for calculating the positions of the moved vertexes but I don't know where to apply it. unfortunately I see no possibility to implement this in shader code.

Re: [osg-users] Add user data to Node_readLocalData Node_writeLocalData
Hi Tamar,
While the .osg ASCI format is officially deprecated I don't have any
plans to remove it's support from the OSG right now so you are safe,
and even if I did remove it from the core OSG you'll be able to use
the .osg support via an external plugin/NodeKit.
The replacement for .osg is the new generic osgDB serializers, these
make it much easier to extend the serialization with support for you
own custom classes. The src/osgWrappers/serializers/* modules all
contain plenty of examples of how one wraps classes to support the new
serialization - just pick an OSG class and look it up in appropriate
serialize directory to see how it's done. The advanage of the new
serializers is they automatically support ascii, XML and binary
versions of the file format.

Re: [osg-users] [osgPlugins] OpenFlight crash reading files with lightPoints - fix patch
Hi Ulises,
I'm curious how a maxPixelSize of zero would be meant to be
interpreted in OpenFlight files. My guess is that a max pixel size of
0 would indicate that you should never see a light point, so in fact
one should simply disable rendering for LightPointNode's where this is
set.
I do wonder if the maxPixelSize of zero might be a bug in the
database, as why would you create a light point that can't be seen...

osgviewer doesn't make it with this files.
After debuging a little, I've found out that the method
IndexedLightPoint::readRecord (RecordInputStream in, Document document) was
setting the osgSim::LightPointNode's maxPixelSize to zero. This is causing
a index out of range exception afterwards in the draw traversal...
I've solved this problem by simply adding a check for zero before setting the
maxPixelSize read from the file.

Re: [osg-users] fire and smoke don't MOVE WITH the model in ??????
Hi Mca Mca?? If you are human I'd guess you have a name that other
humans can use to communicate with you... so it'd be nice is you could
sign with you name.
As for particle systems, ones that have dynamically moving emitters
need to have the emitter under the transform that moves the model and
the particle system that renders it under the root node in world
coordinates. The osgparticleeffects example illustrates this in
action so have a look at this example so see how it manages it.

Re: [osg-users] Full screen with resolution change problem, resources lost
Hi Michael, One doesn't normally need to create a new context when resizing a window. Why do you need to in your case? If you do close a context and assign a new one then you'll need to make sure that you clean up all the OpenGL object handles that the scene graph maintains when disposing of the one scene graph so when you assign the new one it properly recreates all the OpenGL objects. osgViewer has code to do automatically but it sounds like you are doing stuff at a lower level so you'll need to recreate this. See the include/osg/Node for the osg::Node::releaseGLObjects(State*) method that releases all the OpenGL objects for a given context, and include/osg/GLObjects helper functions for cleaning up delete OpenGL objects once they have been released from the scene graph.

Re: [osg-users] How to prepare LOD dataset from a large model file?
Hi Martin, How long are you talking about here? What length of time are you aiming for? What format is the file in? What type of model? What hardware and OS are you working on? Personally I'd try to get the model loading quicker before venturing into more complex tasks like trying to build automatically LOD's and paging. The OSG has great support for database paging but creating the models for efficient paging is far from trivial so it's not something I'd recommend someone does without first exploring the alternatives.

Re: [osg-users] PagedLOD - How to not page a specific node ?
Hi Aurelien, 100Mb of texture and 20Mb of vertex data isn't really that large relative to what modern hardware is capable of handling. There is lots you can do to optimize databases to reduce their footprint, for instance OpenGL compressed textures are an easy solution that can be done with a small amount of pre-processing. You could go to the trouble of creating lots of LOD's or PagedLOD's but unless it's absolutely necessary I wouldn't recommend going down this route as it significantly complicates the creation of the databases. So I'd take a step back and work out what the performance bottlenecks are then solve these. Robert.

Robert, Attached are two screen shots. 'shadow_before' is the base state with a box casting a perfectly fine shadow. 'shadow_after' is where I have rotated the camera such that the box has moved out of view to the right. In this image you can see another clipping edge beginning at the bottom of the shadow that moves relatively vertically as the box continues to rotate to the right of the viewing window. As with the LiSPSM implementation, if I comment out the clipping section (here in adjustPerspectiveShadowMapCameraSettings(..) function), it looks fine but of course is then not clipped at all.

[osg-users] [ANN] osgRecipes: Integrate OSG with almost everything, the second wave
Hi all, I wish someone here still remember the osgRecipes project I've created and announced here some months ago. It included 9 different examples at that time, introducing how to integrate OSG with other 3rdparty libraries and APIs like Awesomium, Micorsoft Kinect, TUIO, AssImp, etc. Now I'm glad to tell you that there are another 9 examples out, with 9 completely new integration examples. They are: * Box2D: a nice 2D physics engine for games * Bullet: A professional multiphysics library, this example is very simple and completely different from the osgBullet project. * libGizmo: gizmo control library for 3D object manipulation, much lightweight than osgManipulator and really easy to use! * MicroPather: a path finder and A* solver, already included in the source code. Consider add AI to your OSG based games now? * MyGUI: a fast, flexible and simple GUI, as good as CEGUI, I think. * ngPlant: a plant modeling software, good for creating trees! * OpenNI: natural interaction devices middleware, another way to use Kinect! * OTL: ODBC template library, for DATABASE I/O with only a plugin! Only tested with Sqllite3 at present * RVO2: Reciprocal collision avoidance for multi-agent simulation. Thanks Christian Buchner for the original osgrvo2 example on osg-submissions All the examples are tested on Windows 7. Hope someone could help me test them on other platforms. You may download the project source code in public domain at: https://github.com/xarray/osgRecipes which is also the code repo of the book OpenSceneGraph 3.0 Cookbook. And see how these examples perform at: https://github.com/xarray/osgRecipes/wiki The TODO list of the third wave (still 9 eamples, I think) of osgRecipes is also listed here for someone who have interests: Berkelium, Microsoft DirectWrite, GUIChan, MathGL, OIS, Recastnavigation, ROBOOP, Sundog Silverlining Triton Call for more integration ideas now. :-) And glad to see some of the examples merged into the core OSG trunk, for example, the OTL database plugin (no dependency), and the AssImp and FreeImage plugins.
