Re: [osg-users] In readNode, find the parent node that will be merged into
Hi Craig, Could you not do the update as a lazy operation, i.e. what for an update traversal to traverse the scene graph and then update it then as the update traversal NodeVisitor will have the whole parental path. The osgTerrain::TerrainTile::traverse() implementation found in src/osgTerrain/TerrainTile.cpp does something similar to this for finding the Terrain node that it's enclosed within.

Re: [osg-users] manual camera view matrix update
Hi,
Thanks for your reply!
Well, I've tried with the osg_ uniforms instead of the typical gl_ uniforms.
Still not good. My model appears but the camera matrix uniform just doesn't
update by using
Code:
_viewer-getCamera()-setViewMatrix(osgMat);
The shader I am using is:
Code:
static const char gVertexShader[] =
varying vec4 color;\n
const vec3 lightPos =vec3(100.0, 100.0, 100.0); \n
const vec4 cessnaColor =vec4(0.8, 0.0, 0.0, 1.0);\n

Re: [osg-users] manual camera view matrix update
Hi Rubén,
Have a look at osg::State::_useModelViewAndProjectionUniforms to see
if it's set to true. For builds the set the CMAke option
OSG_GL_FIXED_FUNCTION_AVAILABLE to OFF this variable should be set to
true by default. This member variable tells osg::State to pass the
projection and modelview matrices setting to the associated uniforms.
Robert.

Re: [osg-users] Skipping nodes in serialization
I was pondering this the other day and it occurred to me that the problem
boiled down to the fact that some (if not all) serializers do not write via a
subclass of NodeVisitor, and hence are unaffected by nodemasks.
I wondered if you could simply make your node so it is ONLY visible to
NodeVisitor traversal by subclassing the node and overriding the traverse
function. e.g.
Code:
class NonSerializedGroup : public osg::Group
{
public:
UnserializedGroup(osg::Group* unserializedGroup)
: _unserializedGroup(unserializedGroup) { }
void traverse(osg::NodeVisitor nv)
{
_unserializedGroup-traverse(nv);
}
osg::ref_ptrosg::Group _unserializedGroup;
}
graffy wrote:
Hi,
I have a graph that I serialize with a simple call to osgDB::writeNodeFile(),
but it contains a node that is auto-generated when the application starts.
Is there a way to exclude that node from serialization? I'm familiar with
the setNodeMask() / setTraversalMask() mechanism used in visitor classes, but
wasn't finding something similiar for serialization - nothing jumped out at
me in the ReaderWriter docs, anyway.
...
Thank you!

Re: [osg-users] [osgPlugins] VRML plugin: help in compiling
Hi Paolo, The openvrml loader is basic right now and cannot handle any VRML file. I suspect that this is what you are running into. If you look at the function convertFromVRML (ReaderWriterVRML2.cpp:~247) you will find that the loader can only handle Group, Transform, and Shape nodes, a subset of openvrml. There have been dynamic casts in there in the past that didn't test for null (failed) results which in turn would cause a crash. If you want to test whether this is the cause of your problem, you should probably start by monitoring entry to the above function and checking the openvrml node type by looking at obj-type().id() (returns a string with node type). You could also look through your vrml file and see whether it uses tags other than the ones mentioned above. -Keith On Wed, 7 Sep 2011, Paolo Piazzi wrote: rmilh wrote: I don't have VS2010.

Hi Laurent, Under Linux there is a valid context returned from glXGetCurrentContext() in LightModel::apply(), so it is unnecessary to create another context as you have done. The depth buffer is set to 8 bits which is unusual. What happens if you set it to 24?

Hi, I'm working with Windows Xp. Before I worked with osg2.8.3 and wxwidgets 2.9.1 with a compatibilty 2.8.0. Hence It was a wxWidgets 2.8.0 for wxGLCanvas.

[osg-users] Stack around the variable 'viewer' was corrupted..?
Hi there, I have spent today implementing a class to handle a Wii remote in a basic console application. When I got that working, I imported the code into an openscenegraph project and everything still works lovely. The problem comes when the program ends. Even if I comment out all of the code associated with my WiiHandler class and just have a skeleton OSG app, the error still appears. Here is my Main.cpp code, just opening a blank OSG scene: pastebin. com/1ASYrpip (remove space, i cannot post links yet :( ) Has anyone else ever had a problem like this? My WiiHandler class is not yet linked up to any form of osg callback, the only way it has to update is by the getScreenPos() function. The fact that it breaks as it is executing the final bracket tells me that it is something to do with OSG's stack cleanup. I take it the dynamic memory is taken care of by the scenegraph (no tutorials i have seen say 'delete root')? Even if that is the case, my heap shouldn't be hitting my stack with a program as simple as this! Can anyone shed some light on the subject?

Re: [osg-users] [vpb] Is the VPB 1.0.0 available?
Hi, I grabbed the svn root of VPB yesterday and have been trying to build it from source using CMake and Visual Studio 2010. I am using precompiled OpenSceneGraph 3.0.0 binaries and dependencies (which include gdal) I was able to configure and generate a Visual Studio 2010 project using CMake and the latest VPB src without any errors or warnings, but when I try to build the project in Visual Studio 2010, I get the following error: Error 1 error LNK2005: public: void __thiscall std::basic_ofstreamchar,struct std::char_traitschar ::`vbase destructor'(void) (??_D?$basic_ofstream@DU?$char_traits@D@std@@@std@@QAEXXZ) already defined in SpatialProperties.obj C:\Users\efahy\AER\GEMS\Scene\VirtualPlanetBuilder\build\src\vpb\osgDBd.lib(osg80-osgDBd.dll) vpb The file osgDBd.lib does not exist at the path in the error. It does appear in my OSG3.0.0 installation directory. This library is found in its correct place by CMake before generating the VS2010 project. I am pretty new to developing for Windows and this is only my second Visual Studio/CMake project so I could be making an obvious error but I thought I'd post this just to see if anyone had successfully build the latest VPB that is in svn/root that supposedly OSG3.0.0 compatible? I'd hate to spend a ton of time spinning my wheels on this if I would be better off waiting for the official VSP1.0.0 release. Any advice or thoughts are most appreciated. Thank you!

Re: [osg-users] Question on decreasing latency for database pagers...
Hi Boon, On Wed, Sep 7, 2011 at 7:04 PM, Boon Wah boon...@gmail.com wrote: After some thought, I want to try to make the paging become more aggressive and load tiles further away from those in view. As my fly-pass is very fast, the paging mechanism must also 'cache' new tiles earlier. I am unfamiliar with OSG and require some help in doing so. Does modifying the setRange for the PagedLOD object help in achieving my objective? You can use Camera::setLODScale() to adjust the range used for PagedLOD child selection, this can be done at the viewer level rather than at the individual node level so it much more manageable . However, selecting high res children will result in a higher load on the CPU and GPU making it more likely that you'll drop frames. If you want to load tiles in quickly then best way is to use a solid state disk. You can also up the number of threads that are doing the database paging, see the DatabasePager API do details.

Re: [osg-users] [vpb] Is the VPB 1.0.0 available?
Hello Ethan
I wonder if you have hit a problem reported earlier. see:
http://lists.openscenegraph.org/pipermail/osg-users-openscenegraph.org/2010-August/044528.html
It is reported as a bug in msvc, and I haven't tracked it for a while.
Try and set /FORCE:MULTIPLE in the linker param section for the vpd
library
A more long lasting solution is to set this in a CMakeLists.txt:
if(MSVC)
if(${MSVC_VERSION} STREQUAL 1600)
message(msvc2010 build fix /FORCE:MULTIPLE)
set(CMAKE_SHARED_LINKER_FLAGS ${CMAKE_SHARED_LINKER_FLAGS} /FORCE:MULTIPLE)
endif()
endif()
I don't have the sp1 for my msvc2010 so I don't know if it fixes this issue
cheers

Re: [osg-users] Intersection of two lines
I am not aware of a function in OSG to do this, however, you can do it yourself. If you have a starting point and direction for each line, you can define each line parametrically as Line 1: P + rA Line 2: Q + sB where P,Q are the starting points and A,B are the unit direction vectors. The scalars r,s are what we want to solve for. This can be done by equating the two lines P + rA = Q + sB or rA - sB = Q - P For 2D, this is a simple 2x2 linear system. The scalars r,s can be uniquely solved for by using Cramer's rule (stable for small systems). Of course, this assumes that the lines are not parallel or on top of each other (check for this first). Once the scalars r,s are solved for, plug them back into Line 1 or Line 2 to get the point of intersection in your coordinate system. For 3D, the system above turns into an overdetermined system of equations (i.e. 3 equations and 2 unknowns) which does not have a solution except when the system contains linearly dependent equations. For the case where there is no solution, you can solve for a point of intersection in a least squares sense using the method of normal equations. This method is numerically stable for small systems. To do this, write the system above as Cx = d where C is a 3x2 matrix, x is a 2x1 column vector containing the scalars r,s we want to solve for, and d is 3x1 column vector. Using the method of normal equations, we can rewrite the system to be CtCx = Ctd where Ct is the transpose of C. This new system now becomes a 2x2 linear system which can be solved like the 2D case above. Hope this helps... -Shayne -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=42509#42509 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
