Re: [osg-users] Load balancing on multiple cores
Hi Jesse, Jesse Stimpson wrote: I feel that we're diverging from what I think is most perplexing about what I'm seeing. When I restrict the process to use less cores, I get increased rendering performance. This is what leads me to believe there are some load-balancing issues. yes, and it would be difficult to see what causes it. Is it OSG, the OpenGL driver or your OS? Unfortunately there is no magic way to get the balance right on all hardware combos. You'll just have to experiment and use what works best in your situation. Also, if I have the OSG process set to both cores and I run another single-threaded process in the background, the other process gets assigned to one core, and OSG rendering speeds up, presumably because it is being processed mainly on a single core. you might find this interesting: http://igoro.com/archive/gallery-of-processor-cache-effects/ I've been playing with the OSG threading models as well. In debug, SingleThreaded mode seems to run the best on my machine. Is there documentation on the implications of the threading models? Not explicitly that I know of. A search in the archives for the long names should get you some discussions. If I understand correctly, SingleThreaded means only the rendering is single threaded, and the database pager is still a separate thread. Is this right? Are reasons we shouldn't consider using SingleThreaded mode? No, use whatever works best for you. We are using SingleThreaded for some of our apps, because they are just a small part of a larger application and we can't use all the resources in the machine for rendering.

Re: [osg-users] Increase image-quality - increase 'Draw' time
Thank you both for your replies. I think this little bit from Robert might be the issue: robertosfield wrote: However, if OpenGL FIFO fills up because the rate at which you are pushing data into it exceeds the rate at which it's been emptied then the application thread will stall and the draw dispatch times will go up. Sometimes you can see some rather no linear draw dispatch times due to small changes in load on the GPU suddenly causing the app to stall. Even when this happens there is still a bit of leeway before you start dropping frames. The workload on the GPU has increased, and I can only assume that it's now not processing the commands as fast as it used to. So since the output is taking longer, and the input is equal, the driver will need to wait for the queue to empty a bit every now and then. We're not changing the amount of data read back from the GPU (I doubt we even read back anything), I'm not changing anything in the program. Brian, if I'm locked to VSync (which I'm not in my test case), and the GPU has more work to do than the CPU, I do NOT expect the command submissions to take longer if I enable these quality options. I'm sending the exact same amount of data and commands, so why would the driver suddenly take longer to queue those commands? The GPU will of course need more time to execute those commands, but I wasn't expecting that to show up under the 'Draw' time, since that time is the 'GPU' time. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=25852#25852 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] MetaFlight loader
Hi Karl, I ended up with DART from Presagis and converted the metaflight into terrapage. Now I can have huge database runing on solid 60 Hz that Vega was not able to even display it. I wrote couple of OpenFlight processing tools to support this conversion though, and from what I experienced, there are some precision problems with connecting tiles where the projection is stored in the db header in the openflight. I used proj4 lib and looks like only Presagis Creator and Creator Terrain Studio can match these correctly, TerraVista and proj4 can not match the tiles correctly. So my approach to have huge metaflight database running in osg is half automated with custom openflight processing tools, half manual with Creator to prepare the data for DART.

[osg-users] light multi-parenting
Hi, I reached some difficulties with handling of lights when I was considering some improvements to osgShadow, like multiple light sources: 1. single light source object can be placed two times to the scene. Because of multi-parenting, the light may have two different transformations. Although one object and one unique pointer, it identifies two light sources, thus it is not unique light identification. When current implementation of ShadowMap::setLight(light) sets the light for shadows, which one of the two should cast the shadows? Definitely, not both of them, at least not with the current light implementation. Options: - The most robust approach is to use paths, identifying the node path down in the scene graph to the light. This would allow proper identity of multiple-parented objects and position of the light would be given by the transformations on the path. - Another approach may use just the first or the last light occurence in the scene graph. - cull-time approach may use first or last occurence of the light in the RenderStage::PositionalAttributeList. - any other options? The first most robust approach is used by Open Inventor and it works pretty good, although it may be considered overkill by some people. My current preference is to use the first position of the light in the scene graph (retrieved from RenderStage::PositionalAttributeList, because it is used in cull-time), and to silently keep all the remaining light occurrences in the scene graph on the same position. When an user will need lights on different positions, he will just create copies of the same light. 2. LightSource question: I was always wondering why there are two light classes - osg::Light and osg::LightSource - and not just one. Is the only purpose for having both osg::Light and osg::LightSource the ability of LightSource to specify ReferenceFrame? Apparently, osg::Light as Attribute can not have reference frame. Any other reasons, or am I missing something? Thanks, John ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] [osgOcean] Problems with Transparent Ocean
Hi Kim, Chris, I have a feeling that it might be to do with the number of variables in the shader rather than the MRT though as I think Umit had the same problem a while back. That's probably the case, the 7 series cards support less uniform variables per shader, and if I remember well we were at the limit already in the ocean_scene shader, so perhaps the recent modifications (transparent ocean surface) put us over the limit. As I said I don't have access to a 7 series card anymore (well I do but I'd have to swap it into a machine) so someone with one of those cards should really debug this.

How do you give a single light source two different OpenGL light IDs? Or do you manage that all in shaders, thus without the restrictions of light IDs? As I understand it, if we're on the fixed pipeline then multi-parenting lights wouldn't make sense because the light would still have only one ID, and the traversal would just use the last (first?) transformation when sending that light's state each frame. How would you handle this? I think you're concentrating on an edge case. It's much easier to concentrate on the general case, which is that you'll have multiple unique lights in the scene, each with only one parent and one OpenGL light ID. Just curious.

I'm hoping that someone can help me with a weird problem I'm having with an
openflight terrain I have.
It seems that when I mesh my terrain (with Multigen Creator 2.5.1) I can't
see it anyore. Note that the problem only occurs when I disable lighting (i.e
GL_LIGHTING). However, when I un-mesh the terrain (seperate faces) then it
works correctly, regarless of the lighting state.
I converted the *.FLT to *.OSG so that I can look at the different between
the meshed and un-meshed version. What I discovered was that the color array
in the meshed version contained invalid RGBA components - they do not
correspond to the color set within Creator. The color should be (1,1,1,1) but
I'm getting (1,0,1,0). So it's normal that I don't see the terrain because
the alpha is 0. The green component also 0, which I can't understand as well.
For example:
Code:
ColorBinding PER_VERTEX
ColorArray Vec4Array 9
{
1 0 1 0
1 0 1 0
1 0 1 0
1 0 1 0
1 0 1 0
1 0 1 0
1 0 1 0
1 0 1 0
1 0 1 0
}
The reason why I want to use the meshed version of the terrain is to improve
rendering performance.
We've isolated the problem in the LocalVertexPool::readRecord() function in
the openflight plugin. It seems that the alphaIndex value extracted from
the FLT is incorrect (see snipit below).
Code:
virtual void readRecord(RecordInputStream in, Document document)
{
[...]
if (mask HAS_COLOR_INDEX)
{
uint32 alphaIndex = in.readUInt32(); [b]// Bad
alphaIndex.[/b]
int index = alphaIndex 0x00ff;
uint8 alpha = alphaIndex 24;
osg::Vec4 color = document.getColorPool()-getColor(index);
color.a() = (float)alpha/255;
vertex.setColor(color);
if (!color.valid())
{
osg::notify(osg::NOTICE)Warning: data error detected in
LocalVertexPool::readRecord color=color.r() color.g()
color.b() color.a()std::endl;
}
}
[...]
}
Obviously, the meshed FLT file could ne invalid, right? So I used a
different application (an old 3D Explorer app) to load the meshed version and
it works correctly.
I can't exaplin it.
I've attached a snipit of the terrain for you to look at. It contains the
following files:
.\gr01.rgb
.\gr01.rgb .attr
.\small_faces.flt : unmeshed version
.\small_faces.osg
.\small_mesh.flt : meshed version
.\small_mesh.osg
Can anyone shed some light of this problem?

Although one object and one unique pointer, it identifies two light sources, thus it is not unique light identification. How do you give a single light source two different OpenGL light IDs? Or do you manage that all in shaders, thus without the restrictions of light IDs? No, because it is one light source, it has one OpenGL ID. As I understand it, if we're on the fixed pipeline then multi-parenting lights wouldn't make sense because the light would still have only one ID, and the traversal would just use the last (first?) transformation when sending that light's state each frame. How would you handle this? Let's expect a large train station model with many trains, each composed of many wagons. The wagons are for passangers and because it is night, there are light sources in the wagons. The wagon model is definitely loaded from file only once and reused, say hundred times throughout the large train station for each wagon (let's expect just one type of wagons). And because the light is stored in the wagon model, each wagon will use the same light for lighting the interior of the wagon (not exterior). The camera can be on any place and I always see through the windows of wagons their lit interiors. The same light is instanced using multiparenting in all the wagons in the train station, still using the same OpenGL ID. This works perfectly in OSG until I start to think about shadows... :-) Maybe, it is a border case, but I wish OSG can handle any scene If I am designing something, I want to do it in a way to handle most possible situations to avoid people having issues. Hope, there is a solution for it. Thanks for your recent comment.

If I were to make a shader, I would access light 0's position/direction with gl_LightSource[0].position. I thought the light's position was global to the whole scene, but in your case, light 0 will have multiple positions... Does that mean that the position is changed for each subgraph in which the light is placed? Do you put any children under the light source, or how do you determine for which subgraph a given light position applies? I'm really surprised this works. And I agree that getting it to work for shadow techniques will be interesting.

Probable Spam] Re: [osg-users] Render to Texture with independent framerate(Solution) Hi folks, I would like to post my solution to the problem of rendering to a texture independently on the framerate of the viewer, the code is attached. My solution is to derived a Viewer from osgViewer::Viewer, added a custom offScreenRender() function mimicking frame() and (offScreen)renderTraversal() function without statistics and swapbuffer. In the offScreenRender() function I exchange the child of the main camera by the off screen rendering node containing only the RTT cameras and switch it back afterwards. This works great except that the shadows do not work correctly in the RTT camera. It seems that the light position is wrongly detected, which is done in the cull traversal as far as I could understand from looking at the code. How do I perform this properly in the offScreenRenderTraversal() function?

Re: [osg-users] Mac Serializer Compile Error
I have attempted to add a ADD_GLINT_SERIALIZER for the cases where I got
errors. I did as Robert suggested and just blindly cast to int.
Figured I'd post here first instead of to submissions since I have no
idea if this will break other builds, but it allows the serializers to
compile for me under the 10.4 SDK.

Hi Martins,
I have no experience in Mac. But it seems that type definition of
GLint changes to some other types in your system. In most other cases,
we have:
typedef int GLint;
in the gl.h header. And an ADD_INT_SERIALIZER is workable with it.
Maybe we should have more tests on 64bit systems and try to find out
if an independent ADD_GLINT_SERIALIZER was required to keep compatible
on different platforms.
An ADD_GLINT_SERIALIZER may well be required. We'd need to
static_cast the GLint to int for portability of the data format.

[osg-users] ANGLE - a possible helper under Windows?
Hi All, I just came across this article that talks about a google project called ANGLE that is developing a wrapper that maps GLES 2.0 calls to Direct3D 9.0. GLES 2.0 being a pretty small subset of full OpenGL makes the task rather more straight forward that wrapper GL 1.x/GL 2.x/GL 3.x, still not trivial but should be make it more likely to succeed. The article is: http://www.theregister.co.uk/2010/03/19/google_webgl_windows_fix/ It's an interesting development as it's well established that some hardware vendors don't support OpenGL well under Windows, so it might make a possible workaround for members of the OSG community. It does mean you'll need to have a GLES 2.0 target in your app to take advantage of this, but this isn't too difficult now that the OSG has GLES 2.0 support. Once we get more mature fixed function to shader pipeline setup this should become even more seamless. I'm no windows hack so I'll have to leave it to members of the OSG community to investigate further, but potentially we could adds support for linking against ANGLE if this project takes off.

Re: [osg-users] MultiThreaded Culling
Yep, got it thanks. It just seemed weird since I'm not a multithreader understander, how you could start the graphics thread before getting to the main frame loop, but at the same time be sure that the culling happens before the draw of the graphics thread. But I guess it just works. Thanks.

I can't seem to trace it in the code. It seems like it should happen in the runOperations function of GraphicsContext when it goes through the camera list, but it seems like that just calls the draw method. My guess would be that it happens in the same thread as the event and update traversals. But one sure way to find out would be to set a breakpoint in one of the CullVisitor apply methods and look at the call stack and thread ID. -Paul ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] How to programmatically clear trackball manipulator's mouse queue
I have some source code where I use a trackballmanipulator to rotate a terrain. If I drag the mouse I can set the terrain spinning. How do I programatically stop this (i.e., without clicking the mouse again)? I tried setting Manipulator-setRotation(last_saved_angles), which does reset it , but it looks like the previous dragging motion queues up lots of mouse events that then continue to rotate the terrain on subsequent render loops.

I don't think it is necessary for directional lights (they are infinitely far away, so don't have a position), but say you want a spotlight attached to a train locomotive. You could update osg::Light's position every time the locomotive moves, or you could attach a LightSource to the locomotive's scene graph and have the light placed correctly automatically.
