[osg-users] DLL versioned MSVC and NMAKE problem, relative paths are wrong
Dear OSG-Users, I am using commandline build system nmake on windows, since the OSG_MSVC_VERSIONED_DLL hack this does not work anymore, because there are hard-coded paths to move the dll's, but nmake has different locations for the files. There are two solutions, 1: change IF(MSVC) on line 142, 158, 299 and 301 of CMakeList.txt (r7885) to IF(MSVC_IDE) This fixes the problem, but the dll's are now not versioned and in the /lib dir 2: change the macro's in OsgMacroUtils.cmake for the IF(NOT MSVC_IDE) situation. Not sure what needs to be changed, but that way we can keep the versioning and /bin placements I was wondering if this change should be in the repository, if so please instruct me to summit the changes, (i'am still experimenting with the solution 2 suggestions are welcome). I am also trying to build on other platforms (linux, sun, aix, hp) not without problems, where can I sent an overview of my feedback?

[osg-users] shadow occlusion culling
Hi all, I was walking through osg::CullSetting code and there i find SHADOW_OCCLUSION_CULLING as one of the Culling mode. Can some body tell me where it is used. best regards RJ ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] How to modify the array of vertex from a Geometry object
Hi,
At this point, I would recommend to use a debugger and enter into the
OSG code with it. It may not be a bug in the OSG code, but maybe by
looking at what OSG is doing you can find how to fix your own code.
As a hint on where to look. The dirty() call should be forcing a new
compileBuffer() call in the next draw stage, and this should mean a
glBufferSubData call uploading the new vertex data to the GPU. If this
is OK, then I would look at the geometry draw() call, to see if it is
using the VBO path or another one.
Maybe Robert can help you a bit more with this when he is back next
week.
Regards.
Rubén

Hi!
I add the vbo-dirty() but it doesn't change anything. I had a look to
the vbo data and it's fine, it changes, but the render is not
updated any idea??

Hi,
I think that the only thing missing is a vbo-dirty()

Thanks Rubén,
I'm trying to use VBO, but I think something is missing... I added
this to the creation of my geometry:
myGeom-setSupportsDisplayList(false);
myGeom-setUseDisplayList(false);
myVertexBuffer = myGeom-getOrCreateVertexBufferObject();
myVertexBuffer-setArray(0,v);
myVertexBuffer-setUsage(GL_STREAM_DRAW_ARB);
myGeom-setUseVertexBufferObjects(true);
and then inside the callback I'm try to modify the vertex data:
osg::Vec3Array *test = dynamic_castosg::Vec3Array
*(testNx-myVertexBuffer-getArray(0));
for(int i = 0; i numVertex; i++)
{
NxMat34 pose = listShapes.at(i)-shape-getGlobalPose();
osg::Vec3f trans = osg::Vec3(pose.t.x,pose.t.y,pose.t.z);
test-at(i) = trans;
}
but nothing changes in the render the object does not move.
Does
anybody know what is missing??
thanks in advance
Crisalix.

a
Geometry object
Hi,
Some hints:
1. Be sure that test-size() is equal to numVertex
2. I don't know what the at method is, I couldn't find it
either
on
the TemplateArray class or the std::vector class. Try with the
vector []
operator, ie: (*test)[i] = trans
3. If you are updating the vertex data once per frame, don't use
display
lists, it is the worst thing that you can ever do! It is cheaper
even to
use direct mode. Use vertex buffer objects and configure the VBO
(getOrCreateVertexBufferObject) in streaming mode
(GL_STREAM_DRAW).
Hope this helps.
Regards.

Hi Cedric, I am the developer of osgSWIG. You can find scripts in src/Languages/Python 1) run wrap.sh 2) run compile.sh I know this is very much suboptimal and might not even work on your distribution. I am working on a CMake based build system which probably solves quite a lot of problems. There is also one big issue I am facing with one of the headers in core OSG. You might stumble upon the same thing, there are three const variables in osg::Vec3f which use the C++ style of declaration and are not supported by SWIG 1.3.30 /H Cedric Pinson wrote: I have found http://code.google.com/p/osgswig/ to bind osg to python, i did not try yet.

I tried it but i have a problem i can't create vec3array or i dont know how to do that. I imagine it's not so easy because of template ... let me know if it's possible.

Re: [osg-users] osg python binding
I' m also interested in scripting: tried introspection based osgLua and osgPython with not much success. Also tried binary version of osgSwig (version 2.1.11 I presume), was able to run viewer.py but not much more. I did not found many python examples, neither in any of the project above, Is it because the wrapping is not yet stable or like the example are left as an exercise to the reader Any available example scripts would be really appreciated by a novice python user as I am. Iwould also be very intersted in CMake building, and willing to help expecially under Windows platform. Thanks Luigi Hartmut Seichter wrote: Hi Cedric, I am the developer of osgSWIG.

Re: [osg-users] osg python binding
I have worked with the swigged version of osgPython for some time. It works pretty well, I updated the online version (to osg22) and added python style vectors, cmake system and some other extra's It is part of a bigger library, maybe I can seperate it, and share it. It uses the swig system of cmake and works on both windows and linux. As far as I know the swig osgPython is the best solution at this moment for osgPython.

This looks simple enough :) Can I incorporate this into the trunk? I would probably use osg/io_utils for the __str__ wrappers.

Dear osgPython users,
About the problem with vectors,
There is a file in our library, called osgPyExtend, which creates python access
to vectors and mat.
I have attached it.
add %include osgPyExtend.i to osg.i
I have more additions, but this one should be an easy to add.
