Re: [osg-users] osg 2.8.3 : applyAndIncrement of BIND_PER_VERTEX attributeMaps
Hmm, I think I can answer my own question. Code ended up in the drawImplementation "slowpath" which is not well supported. The workaround is to make sure it never ends there. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=44006#44006 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] osg 2.8.3 : applyAndIncrement of BIND_PER_VERTEX attributeMaps
Hi,
I am not sure if I am missing something obvious here , but in the 2.8.3
implementation of Geometry::drawImplementation
There is a loop over primitive types as abridged below
Code:
for(DrawElementsUInt::const_iterator primItr=drawElements->begin();
primItr!=drawElements->end();
++primCount,++primItr)
{
if ( extensions->isVertexProgramSupported() )
{
DrawVertexAttribList &list =
drawVertexAttribMap[BIND_PER_VERTEX];
for( unsigned int i = 0; i < list.size(); ++i )
{
list[i]->applyAndIncrement();
}
}
}
What this suggests to me ( and what I am seeing ) is that in the body of the
loop over primitives , then for each [BIND_PER_VERTEX] attribute list,
applyAndIncrement will be called - this increments the index_ member of the
DrawVertexAttribList .
BIND_PER_VERTEX attribute arrays will have a size to the number of vertices.
If the number of primitives is greater than the number of vertices, then a
vector[] out of bounds exception on the vertex attribute array will happen when
the primCount exceeds the vertex count.
Thank you!
Cheers,
Andrew

Maybe I just don't understand how the renderbins work. Am I correct in assuming that for example the root node would have several numbered bins, each with the ability to have a depth sorted bin, a traversal bin, and a state sorted bin inside them? It seems that no matter what I do, the last sort order I set in the hierarchy is the only one that does anything.

Re: [osg-users] Problem loading IVE files
Hi and thank you again,
what you are saying is logical for me, but I am pretty sure that I didn't
rename that folder. In which step is defined that folder? As far as I
remember, I put the dependencies in the 3rdparty folder and run the cmake. I
have checked the cmake options, but I have not found where this plugin
folder is defined. How can I check that I am using the right dependencies?
The dependencies listed here are the right ones for osg 3.0.0 or for any
other version?:
http://www.openscenegraph.org/projects/osg/wiki/Downloads/Dependencies
Anyway, it is strange that the rest of the plugins are properly working. I
thought that IVE should be easier to be working than DAE, for example, which
is working for me.
Cheers!

Hi,
The plugin folders name does correlate to the version of the OSG that was
used to create the plugins. This is done to avoid loading plugins from a
different version of OSG.
This looks like your problem.

Hi,
thank you for your reply and sorry for the delay in my answer (I was on a
trip). Yes, I am using 3.0.0. What you can see in:
LoadLibraryA("(.)\osgPlugins-3.1.0\osgdb_ived.dll")
is not the OSG version. This is just the name of the plugins folder that,
for some reason, has been called 3.1.0, but I think that it is not related
with the actual version of OSG. If I am wrong, please let me know. :)
Anyway, I am still at the same point. I can load 3ds, dae or osg files, for
example, but still not possible to load IVE files.
Cheers!

Hi,
Just checking you don't have multiple version of OSG in your path. You said
bellow that you are using version 3.0.0 of OSG yet the output you posted
from dependency walker lists OSG version 3.1.0.
If you do have both version on your path, this could be your issue.

Re: [osg-users] where is libosgQt in osg2.9.16?
Hi Lv, libosgQt should be built as long as you have Qt installed, check that cmake has found Qt. I would recommend moving to 3.0.1 as this is a stable release, I can't see a reason why one would move to 2.9.16 rather than 3.0.1. Robert.
