There is one example actually using 2 ids, OSGTextureObjRefChunk.
This one has a oglGlId and an osgGlId if the OSG id is set the normal
OSG validation/mapping is done. If the oglGlId is set only the GL calls
are made. If both are set, the OpenSG id wins ;)
If there is a need to reference OpenSG internal properties this might be
the way to go.

The reason behind that is that on Linux (where I spend most of my time) I can directly build against OpenGL 4.x libraries. OSGGLFuncProtos.h is build in a way that I can switch between the window based extension mechanism and direct linking. What I usually do if I need newer functionality which is not inside either OSGGLExt.h or OSGGLFuncProtos.h depends on the system I'm on. On Linux I just define GL_GLEXT_PROTOTYPES before anything else and am done with it. On Windows I use glew (set OSG_ENABLE_GL_INCLUDE_GLEW to TRUE and make sure glew is available). The only trick is that one has to intialize glew at the right time. Once I'm done testing I pull the required things over to OSGGLExt and OSGGLFuncProtos.

Re: [Opensg-users] OpenSG 2: Setting up the depth buffer
Hello, I added a new OSGFBOBackground which takes a FramebufferObject and on clear tries to blit all color, depth and stencil buffers, either to the active FBO or to the window framebuffer. I only came around to do some quick testing, but it gives you something to start with (and ideally it already does what you need). I will do some further testing, especially on robustness. kind regards gerrit -- ___ Opensg-users mailing list Opensg-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/opensg-users

It boils down to shaders being cached during the traversal and remapped to a different object. So the frontend objects does not do any actual OpenGL calls. The easiest way around this is to use a SimpleSHLChunk instead if one wants to activate the shader directly. kind regards gerrit -- Full-scale, agent-less Infrastructure Monitoring from a single dashboard Integrate with 40+ ManageEngine ITSM Solutions for complete visibility Physical-Virtual-Cloud Infrastructure monitoring from one console Real user monitoring with APM Insights and performance trend reports Learn More http://pubads.g.doubleclick.net/gampad/clk?id=247754911=/4140 ___ Opensg-users mailing list Opensg-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/opensg-users

I have a look, currently all the file information is collected and
temporarily stored. I would probably add a OSG_ADD_GLOBAL_EXE_SRC to
have a distinction between libs and executables.

Your patch looks ok, though I'm still not sure where the subtle difference is ;). Is it easy to dump a dot file for this case. No it is not :-( The model with which I have worked on the issue was rather big and I did have a complicated procedure list to reproduce the error. I was able to find a way to get imho to the cause of the problem in function 'void ShaderCacheTreeV3ObjectT, LevelBits::sub(UInt32 uiIdx)' but can't remember the steps which have taken me to this place in detail. The problem is the missing '0x != (i uiCurrBits) ' part in the second 'if' statement. This leads to remaining entries in the cache which do pop up later on. ok, I see, that was the bit I missed ;(. I do have some dot files and logging of instrumented code of the original case. But I'm not sure that this information is of any help for you. Attached you find what I do have. The session goes from program start to crash. I did have the code somehow instrumented by adding member '_oDbg_store' in the ShaderCache. I fill this set in the 'updateRemoveCallback()' function for each 'addDestroyedFunctor' call. The crash happens since this set is not empty in the ShaderCache destructor: ss ShaderCache::dtor = std::hex this still in _oDbg_store = *iter; For this reason, the living objects carrying the callback 'ShaderCache::removeShaderVar' due to the 'addDestroyedFunctor' calls, might execute the callback in the already destroyed ShaderCache object. After inspection of the code I have found that the 'removeShaderVar' function do not remove all entries in the '_oVarTree.sub(uiVarId);' call. I hope I could give you enough information to tackle the issue. thanks, I committed the patch as it looks fine.

Re: [Opensg-users] How to use StereoBufferViewport
Hi,
you have to replicate what you did for the camera decorators for the
viewports as well. So you need StereoBufferViewports, one for the left
eye with
svpleft-setLeftBuffer(true);
svpleft-setRightBuffer(false);
svpleft-setCamera(cameraDecoratorLeft);
and one for the right eye, with
svpright-setLeftBuffer(false);
svpright-setRightBuffer(true);
svpleft-setCamera(cameraDecoratorRight);
than add both viewports to the Window.
Source/System/Window/testStereoDecor.cpp has some examples for
reference.

I have uploaded the files to

thanks, with shaders I'm seeing a the same flat appearance on ATI
cards and correct shading on NVidia card.
ok, beware, we are entering the murky waters of vertex attribute
aliasing. Which IMHO causes the main problems between NVidia and ATI
hardware/drivers in your case, and in general. As far as I understand
it, when using vertex attributes with shaders in an any kind of
compatibility profile (I'm counting #version 120 as one) only
gl_Vertex/location 0 is guaranteed to alias correctly. All the others
might (NVidia) or might not (ATI), were should not is correct according
to the spec. Also, in compat mode you can't bind anything explicitly to
location=0 in your shaders, so here comes the 'ugly' mix.
Could you try the following vertex shader for your setup, which
makes use of gl_Vertex being aliased and the normal being explicit
specified.
//#version 150 compatibility
//#extension GL_ARB_explicit_attrib_location : enable
// or
#version 330 compatibility
out vec3 vTranfNormal;
out vec4 vPosition;
layout(location = 2) in vec3 glNormal;
//
// Compute the normal
//
vec3 fnormal(void)
{
vec3 normal = gl_NormalMatrix * glNormal;
normal = normalize(normal);
return normal;
}
void main()
{
gl_Position = ftransform();
gl_ClipVertex = gl_ModelViewMatrix * gl_Vertex;
vTranfNormal = fnormal();
vPosition = gl_Vertex;
}
Could you try this one and let me know if it solves your display
problems. If you need more attributes (colors/tex coords) you have
to provide the corresponding layout statements in your shader.
Coming back to another point in the thread:
OSG_ENABLE_NEW_GEOHANDLER=ON
I finally fixed to OSB loader problems (a while ago), so this option
will disappear rather soon and the =ON case will become the only
available option.

Re: [Opensg-users] Using per-instance Vertex Attributes
Hi,

Hi all,
for instanced rendering I want to give the instanced Geometry core an
attribute that represents a per-instance position offset. I know how to
set the usual indices and positions, but how do I add custom vertex
attributes?
I tried setting the property to binding location 1 using Snippet
geo-setProperty(offsets, 1) but this causes the following warning:
Snippet
WARNING: GeoVectorProperty::activate: Non-Generic attribute nr. 1 unknown!
and this approach does not work (the instances are not rendered with an
offset).
I also tried misusing the colors property, but even though I set its
divisor to 1 it seemed to be advancing per vertex, not per instance.
Am I even on the right track here?
yes, this should work.
Or do I have to set some properties in the GeoInstancer?
no, just the base geometry and the number of instances.
e.g. from the CSM example
core GeoInstancer
{
numInstances 4
baseGeometry USE BaseGeometry
}
first quick one (and sorry if you have), have you looked at/tried
Examples/CSM/Instancing/SimpleDivisor ?
If yes, there is something weird going on with the example. Using
vec4 vVertex = gl_Vertex + vec4(
gl_MultiTexCoord7);
results in wrongly scaled/projected instances. This can be fixed by
changing the vertex position computation to
vec4 vVertex = gl_Vertex + vec4(
gl_MultiTexCoord7.xwz, 0.);
The example uses attribut 15, but I quickly tried 1 and 3 and it works
as expected.
If you can, could also send me a .osg dump of the subgraph containing
the instancing (off-list is fine) and I can have a further look.
kind regards

I have applied a simple phong shader with removed ambient light. All is correct here. 13_Shader.png Now, I create new additional geometry the same way as I did before. The shading is completely lost. However, I tested that the shader is still working properly. 14_NoShader.png == Now, I disable the shader usage. See that the increase of brightness due to the additional ambient contribution. But, the lastly added geometry still does not render correctly! 15_NoShader.png == Creation of new geometry work now as expected. Rendering of first and third geometry is correct. Second geometry is incorrect. 16_Shader.png Shader activated again, first and third geometry correct, third geometry incorrect. 17_Shader.png New geometry, which renders incorrect. Etc... In order to get a little more information, I did modify my phong shader so that the diffuse contribution is equal to the normal direction. I.e. I used Diffuse = (n + vec3(1,1,1)) * 0.5; // += Kd * n_dot_l; The result of this can be seen in the second group of images: 21_NoShader.png == Start of app with disabled shader support and create some geom. 22_Shader.png Activated shader usage.

For that icon rendering everything works as expected. The main rendering then creates in SimpleSHLChunk::handleGL() the shader, programs but does not update the uniform variables as they are not marked as changed.

The compute shader should modify the texture of a plane, but it never gets activated. do you mean there is no OpenGL call to launch the compute shader or is the texture simply unchanged? My current setup is as follows: I load the OSGContribComputeBase Library using OSG::preloadSharedObject(OSGContribComputeBase) Snippet before I call osgInit(argc, argv). Then I set up my scene. The root has two children: a node with a geometry core which consists of a plane with a texture (ChunkMaterial with MaterialChunk, TextureObjectChunk and TextureEnvChunk) and node with an AlgorithmComputeElement core which holds the compute shader. The compute shader setup looks as follows Snippet NodeRecPtr computeNode = Node::create(); AlgorithmComputeElementRecPtr computeElement = AlgorithmComputeElement::create(); ComputeShaderAlgorithmRecPtr computeAlgorithm = ComputeShaderAlgorithm::create(); _comp = OSG::ComputeShaderChunk::create(); _comp-addUniformVariable(destTex, (int) bottom_tex-getGLId()); This looks suspect. I haven't used compute shaders (through OpenSG or otherwise), but normally texture uniforms are set to the texture unit the texture is bound to, not the OpenGL id. Shouldn't bottom_tex be added to MFTextureImages of computeAlgorithm (this makes sure the texture is activated before executing the shader)? The id returned by getGLId() is _not_ an OpenGL object name, it is simply an id OpenSG uses to access the actual OpenGL object on different contexts. You can use that id together with a context (i.e. OSG::Window) to get the real OpenGL object name (Window::getGLObjectId()). Carsten is right, it should be the texture image unit, I would guess 0 in this case, the MFTextureImages index in general. One further note, as the compute node is part of the tree you have to make sure it is not culled away. Either put the compute node as a group above the plane / element you want to render (this is what Examples/CSM/NewShader/Compute does) or set the compute nodes BBox to inifite and static. kind regards gerrit -- Is your legacy SCM system holding you back?

I'm writing this on my phone so I can't look at the code, but it should not be able to do anything with the actual OpenGL context, so I'm not sure which connects it sets to NULL. it's a bug, it runs through a code path that does not check the passive flag before deactivating. I'll have a look. kind regards gerrit-- Start Your Social Network Today - Download eXo Platform Build your Enterprise Intranet with eXo Platform Software Java Based Open Source Intranet - Social, Extensible, Cloud Ready Get Started Now And Turn Your Intranet Into A Collaboration Platform http://p.sf.net/sfu/ExoPlatform___ Opensg-users mailing list Opensg-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/opensg-users

Re: [Opensg-users] Bug in OSGShaderProgram.cpp
Hi thanks for the detailed report, I'll have a look. kind regards gerrit On Thu, 2014-04-10 at 18:20 +0200, Marcel Weiler wrote: Hi, I have found a bug in OSGShaderProgram.cpp: If you set a shader source of a (Simple)SHLChunk to an invalid source code, ShaderProgram::handleGL(...) will delete the shader in line Snippet 769 and uiShader will be set to 0. If you then set the shader source to a valid source again, uiShader will still be 0 and no new shader is created. Because there is no shader object to compile, the compilation of the new shader source will fail (line 723). OpenSG then tries to get the error log. In line 732 it queries GL_INFO_LOG_LENGTH, but uiShader is still 0 and so the returned value in iDebugLength is invalid. In my case iDebugLength was negative, which when OpenSG tries to reserve a buffer, is cast into a very large unsigned number and causes a Snippet std::bad_alloc. Possible solution: Line 645 is a commented if-condition which once checked if uiShader equals 0. The condition was replaced with if(mode == Window::initialize), but after initialization this condition always evaluates to false. When by using the debugger I make the program go into the new if-block a new shader object is created and everything works well again. I think both if-conditions should be combined with a logical OR ( if (uiShader==0 || mode == Window::initialize) ). This should remove the bug. The modified example file I attached to this mail causes the problem I described. Initially a valid shader is active. If you press 'x', an invalid vertex-shader source will be passed to the SimpleSHLChunk. Until then nothing bad happens. If you press 'x' again, the original, valid shader source is passed to the SimpleSHLChunk again and the program crashes. I hope the information I provided helps to solve the problem.

good news number one, I could reproduce it for the Windows and ATI

If I disable the display lists at the startup of your test
int main(int argc, char **argv)
{
OSG::osgInit(argc,argv);
OSG::FieldContainer *pProto =
OSG::Geometry::getClassType().getPrototype();
if(pProto != NULL)
{
OSG::Geometry *pGeo = dynamic_castOSG::Geometry *(pProto);
pGeo-setDlistCache(false);
}
I get the correct rendering for the Windows ATI combination.

Hi, On 30 Jan, 2014, at 16:28, Johannes jbru...@datasolid.de wrote: Hi Gerrit, are you listening? yes, only it's new year over here, so I'm at home. Therefore: 祝大家新年快乐 ;) I would like to try/use the new instancing geometry. After regeneration of the documentation I could not find anything about the files residing in folder Source/System/NodeCores/Drawables/Geometry/Instancing. A little search showed that flag OSG_ENABLE_NEW_GEOHANDLER is necessary for these files to be part of the build. However, I can't overlook the implications if turning that flag to true. if there are any negative implications these are bugs. There is still one with the osb loader as one combination of vbo/vao crashes, at least on linux. But I plan to fix this one very soon. This one is actually the reason why I haven't removed the old drawing/gl handling code from the geomety. After rereading the options again I realized that I likewise have problems to explain some of the other options properly. Could you shed some light on it? I'll try, but I traveled home without my laptop, so some I might have to defer until I'm back on Tuesday. Typing a lot on an IPad is not much fun. What are the current limitation of the provided instancing infrastructure with respect to ARB_draw_instanced, ARB_instanced_arrays, ARB_draw_indirect, ARB_base_instance and ARB_transform_feedback_instanced? currently I only implemented instancing based on glDrawElementsInstanced and glDrawArraysInstanced, but the base vertex, base instance variants could be implemeted the same way. Indirect drawing hasn't made its way into OpenSG. Into the tranform feedback variant I haven't looked yet, but that might take some time before I can squeeze it in. The instancing information itself is not part of the geometr core, but is stored in a different core (geoinstancer). That one references a base geometry for drawing. Do you have any example how to use the new instancing properly? Only with CSM (Examples/CSM/Instancing). What I haven't put in yet is reading the instance parameter from a texture, this is work in progress. Similar, I'm interested to know about VAO (ARB_vertex_array_object) and VBO and their connection to display lists in the context of OpenSG. VAO/VBO are a platform dependent nightmare. In general the Vao part can not be inside a diaplay list, so you are left with only the draw calls inside the list. I would tend not to use display list with vao's. For the csm I build a test for all geometry index and vbo/vao/display list variants (Examples/CSM/Models/IndexVariants), but this one runs of a script (which I haven't ported to windows), but it is a place to check if in doubt. Note some combination won't render. Currently I haven't tried to put in code that falls back to something that actually renders an invalid combination. Inside the sh scripts is a table with expectd results (no pos, no fallback means nothing is rendered). The same set exists in the instancing example dir. Additionally, I would like to play with the complex scene manager. Are there any options which must be properly set in order to run the examples? the easiest is just to pass the directory of the example (one with a params.csm file) as the only parameter. The param.csm is actually just a shortcut to store the appCSM parameters in a file (I'm just lazy) I hope that my questions are not to blunt, but I would like to dive more into modern OpenGL by means of OpenSG. no problem, ask away, usually you learn something while explaining ;) Best, Johannes On 29.01.2014 19:40, Carsten Neumann wrote: On 01/29/2014 10:21 AM, Johannes Brunen wrote: I would like to ask for some background information about the following OpenSG build options: OSG_ENABLE_OGL_VERTEXATTRIB_FUNCS that one I have to check after returning home.

It came to me like this, as the result of the DAE/FBX exporter from exporting a node named _entity_balken01, into a file named _entity_balken01.dae ;-) So really a special case, but to please Maya .. hmm, does the scene name depend on the file name or the node name ?. I'll have to check if one can resolve it by doing local library searches if the internal collada lookup fails. In your case it finds the node first and fails on the following downcast to scene. For the general loading problem I committed a fixed. Now the loader checks for invalid indices (have to check all for primitive types though) and removes any index with -1 in it. As this leaves you without any texture coordinates I added one option to the collada loader (tryMergeInvalidIndices). In this case the loader checks if it can merge multiple invalid indices into a valid one if the -1 blocks do not overlap, e.g. for something like: index1: 1 2 3 4 -1 -1 -1 5 6 7 8 index2: -1 -1 -1 -1 11 12 13 -1 -1 -1 -1 the loader will merge: index1: 1 2 3 4 11 12 13 5 6 7 8 index2: reuse index1 As this is the case for your file you at least are able to get a geometry with texture coordinates out of the loader. kind regards gerrit -- October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.

I tried to enable combineblend and also attached a DepthClearBackground to the viewport, but that didn’t helped. Does anybody knows why? My layout is the following: ShadowStage - CustomHDRStage - VisitRenderTree my guess would be that the buffer gets cleared when generating the shadow maps - for which ideally you'd want the HDRStage to be a no-op. However, the HDRStage does not really have a good (any?) way of knowing that it is being visited as part of a pass that renders shadow maps, so I'm not sure what to suggest :( ok, I'm looking into it right now as Christoph still has the same problem. For the case with only shadow and hdr stage the setup should actually be the other way round, e.g. HDRStage - ShadowStage - Scene as the HDR stage is a simple postprocessor. I would expect it to run last in all cases. I'm nearly done so that the shadow stage respects the target buffer format set by a parent stage. I hope to commit this later today (latest tomorrow). Once this is done I will add our SSAO implementation and see how this best fits into it. Let me run some basic tests with this setup first so I get all the implication of the g-buffer part.

However, the _mfChunks of the parent is never changed and that is actually what is evaluated in the MaterialChunkOverrideGroup renderEnter() function. Maybe the implementation of this function does make wrong assumptions about the chunks container content? hmm, it seems to me MaterialChunkOverrideGroup should iterate over the chunks of the State returned by PrimeMaterial::getState(). That would also make it work with materials not derived from ChunkMaterial. This is made a bit tricky by the fact that State does not allow easy iteration over it's contained chunks. looking at the code it might actually make more sense to let the material do the work instead of the other way around.

Unfortunately I don't know that part, sorry. It is the incomplete beginning of doing more complicated rendering algorithms. Usually the RenderProperties are meant to be set for the action by the corresponding stage. For example we are currently finishing an SSAO and LPV stage for better lighting. As both of them are deferred shading algorithms the primary rendering has to produce the buffers required by the post processing. So the stage sets the action RenderProperties do indicate that the rendering should create the deferred buffers. Of course the material currently have to be manually setup to support this. To some extend I hope to automate this later on. kind regards gerrit -- Free Next-Gen Firewall Hardware Offer Buy your Sophos next-gen firewall before the end March 2013 and get the hardware for free!

Re: [Opensg-users] OpenSG 2: ShadowStage with PassiveBackround

The least invasive solution I can come up is to have the ShadowStage leave a correct Z-Buffer (which currently is not happening) and draw the additional elements after the OpenSG rendering finishes. This seems to get rid of the artefacts for my example. Would this change in order be possible for your situation, e.g. on the way in through the passive windows you only clear the buffers, than call passiveWindow-render(); and than call the functions that draw the additional elements (e.g. the box with the greenish floor) before swapping the buffers ? kind regards, gerrit -- Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.

Hi,
i am trying to get OpenSG 2.0 running with CUDA 5.0 and Windows 7.
Compilation of the OSGContribCompute project worked fine (after i
uncommented the line
SET(${PROJECT_NAME}_DEP_TEST_INCDIR OSG_GLUT_INC_DIR)
in the CMakeLists.Lib.OSGContribCompute.txt, otherwise the GLUT functions
would not be found).
The testSimpleCudaComputeOSG can be started but as soon as the CUDA
execution branch is triggered, the application crashes at the call to
'cudaGLRegisterBufferObject' within the function
'updateGeoOSGCudaCallback' (Unhandled Access violation exception).
The CUDA programming guide specifies that before any CUDA interop call,
'cudaGLSetGLDevice' has to be called. So i added
cudaGLSetGLDevice(0);
after GLUT was initialized. I also replaced the function with
'cudaGraphicsGLRegisterBuffer' since 'cudaGLRegisterBufferObject' is
deprecated, but to no effect.
I set up a simple stand-alone CUDA application in Visual Studio 2010 that
calls this function without problems.
Any idea? Does anyone use CUDA and OpenSG?
I'm just coming back to this. I just managed to get the cuda part
compiling against cuda 5.0, but I haven't had time to look at it
further. Give me a little time, I'll update you once I get it running
again.

For a more structured approach I added some simple geometry variants
(Examples/CSM/Models/IndexVariants/{Multi|Single|NoIndex}) to the
examples, could you use testWindowGLUT to run through them and let me
know the result for each of the runs. Just renders quat or does not
render quat is fine. Note some examples contain invalid combinations
and won't render something anyway.
There are three scripts in there to run through the examples but you
might need to tweak the path settings.
Could you also send me your CMakeCache.txt from the build dir so I have
a better idea of your settings.

Hi, On Fri, 2012-11-23 at 21:48 +0100, Alexander Lang wrote: Hello, i would like the client application to remain responsive after the connection to the render servers has been initialized. The MultiDisplayWindow::init() function blocks until all render servers have connected, therefore i would like to call init or initAsync on the MultiDisplayWindow instance in another thread. I changed the code of the testDynamicClusterClient.cpp file (attached) such that on connection request a thread is created that operates on aspect 1. After that, the function in the main thread returns. The MultiDisplayWindow pointer is changed to a MTRecPtr such that it will be available in the connection thread. After the thread is synced to the main thread, initAsync is called. Once a server connected, the thread waits on a barrier. The main thread continuously polls if the thread is waiting on the barrier and if so, pulls the changes from the connection thread to the main thread. The connection thread then finishes. This works until i want to disconnect. Setting the MultiDisplayWindowMTRecPtr to NULL does not free the object, the connection is lost but the server window is not closed. At this point only the main thread exists, therefore i am puzzled what could keep the window from being destroyed. Any ideas? P.S. How about an explicit ClusterWindow::disconnect() that would set any pointers that refer to the window instance to NULL, like the WeakPtr? hmm, this has nothing directly to do with the clustering. It is more related to the multi-threading in general. I'll have a look. kind regards gerrit -- Monitor your physical, virtual and cloud infrastructure from a single web console.

What is happening goes as follows: After creation of my scene manager and the embedded ShadowStage object, my composite viewer (managing the viewports and the RenderAction) calls redraw which comes around in the ShadowStage::renderEnter method. This method then calls this-setData(pData, ..., ract), with a just created ShadowStageData object. Inside of this call a connection between the RenderAction and this StageData instance is established. Now on destruction of my composite viewer the render action is destroyed. This leads, by the established connection, to the destruction of the ShadowStageData instance. But, the setData(...) call also establish a change handler between the ShadowStage and the ShadowStageData instances. Now on destruction of my scene manager instance the embedded ShadowStage object is destroyed. This, however, yields to a change message to the already destroyed ShadowStageData instance. I think that this is not a destruction order problem since the my scene manager does have an idependent lifetime from the composite viewer.

I (partially) see the point of calling QT4Window::init from initializeGL, my worry is how to prevent other OpenGL calls as they might crash the application.

Is it possible to move all of the INSTALL_xxx, OSGAllXXX and DocXXX targets into an extra folders for convenience? What do you and other think? I move the INSTALLXXX targets into a folder. For Doc I currently only have one, so I left this at the top level. 3. The simplePluginApp target could also be moved from the top level? same as 1, for me it sits in the Tests folder. 4. The OSGAll target could be moved into the CMaklePredifinedTargets folder as well? I would tend to leave the OSGAllXXX targets at the top level as these are the once I use cross system. To make the toplevel less crowded I moved the regular libs to folders (OSGCoreLibs, OSGContribLibs) as I only use them once something goes wrong and the OSGAllLibs target fails.

Re: [Opensg-users] Evaluation of OpenSG as scene graph library for embedded devices
Hello, sorry for the delay. On Tue, 2012-08-21 at 05:56 -0700, Mirko Oertle wrote: Hello, thanks for your answer. When we have the worst case, than all numbers happen :-). Performance and memory foot print are major issues on embedded devices. hmm, unfortunately OpenSG definitely has some overhead here, some of which we have to address also for the desktop version but I haven't had time to do a thorough profiling so far. You cant compare it to any desktop environments. So the memory and performance overhead of the library is important. It seems that we have to look deeper into it with a test app. What do you think how difficult a port of the library to EC7 or CE 6 could be? Recently I only tried IOS and and least a simple model came out ok. As for embedded Windows, I haven't looked at the latest version and the quick glance left me more confused trying to make sense of all the variants ;(. It also looks like the SDKs are not as freely available as before, so a quick test seems to be not as straight forward as with earlier ce versions. I'll see if I can get access to one of the SDKs. The main issue (which is still unsolved for OpenSG in general) is handling GLES2, so far what exists is more a quite basic approximation. I never had time do completely implement support for it. The good thing is this is something I can look at independent of the platform, and something I wanted to for quite some time now, so I can give support on these parts. The other part is boost as this is the only external library OpenSG requires to build, all others are optional. If this is not readily available porting will be painful. kind regards gerrit -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

I hesitated to upgrade my MacPro because of this issue, but I will do so, as soon as possible, because what you suggested actually makes a difference, even if it is not quite as you suspected. I deactivated the dynamic switching and chose between the internal and discrete setting. The internal setting, referring to the Intel Graphics Card results in a nice torus drawn in 01hello. The discrete setting, referring to the NVidia Graphics Cards, results in an empty window, when 01hello is called. I am relying here on what the application (gfxCardStatus 2.1.1) told me, because 'internal' and 'external' are the only options I can choose, and pop-up notifications then tell me, which graphics card is in use. I'll check of there is the possibility to save a trace from the debugger. I'll also see if I can get access to a 10.8 machine. On monday, I will upgrade my MacPro to 10.8.1, which has a NVidia graphics card only, and let you know, if the issue still occurs. So far, thanks for the tip! short update, I upgraded ours and 01hello seems to work (the torus comes up), the only difference is, that one has an ATI card, but from my experience hardware behaves more uniformly under OS X, so that should hopefully not matter that much. Only for some tests (csm) I lost the mouse input, not sure why ;(. One thought, could you try testWindowCocoa on the discrete nvidia card, not that glut has an influence. kind regards gerrit -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

However, if your application calls OSG::commitChangesAndClear() after rendering, all changes that were done as part of rendering are lost - the only safe time to clear the changelist is immediately after transmitting it, but the ClusterWindow lumps the transmit together with rendering so that it is difficult for the app to clear the CL at the right time. It seems ClusterWindow should have an option (default: true) that controls if it clears the changelist after transmitting it. small comment, changes during local rendering should never be needed to get the clustering right. Usually they should not even be transmitted. Because, rendering locally on the master while clustering is optional, for example on our main cluster the application is started remotely, without anybody being even being logged into the master, so no rendering will happen in this setup. kind regards gerrit -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
