You are right... i have now implemented fxaa to achieve the desired behaviour.
Thank you!

Hi,
According to
http://www.opengl.org/registry/specs/EXT/framebuffer_multisample.txt all your
attachments need to have the same amount of samples.
Cheers,

Hi Gianni,
If you want to remove and add back StateAttribute to a StateSet you have to
mark the StateSet's DataVariance as DYNAMIC, otherwise the draw thread will
overlap the update traversal and contend on the data structure and crash.
Setting DataVariance to DYNAMIC isn't ideal though as it brea

Thanks Robert for the reply.
I suspected a thread issus but since osgFX::Scribe code does not do anything
special regarding thread safety I expected my code should work fine as well.
Can you see the point in my code? Or maybe a threading issue in OSG code? The

HI Gianni,
My guess would be that you've introduced a threading bug by
creating/destroying state objects in the scene graph whilst it's being
rendered.
If you want to toggle on/off behavior like this considering using a
NodeMask on the wireframe portion of the subgraph and just toggle the
wirefra

Hi,
when attaching a textures to a camera one can define separate values for the
parameters multisampleSamples and
multisampleColorSamples for each attachment.
In my specific use case i want to enable multisampling for COLOR_BUFFER0 and
disable it for all other color buffers (e.g objectid and

I used osgFX easily but it seems the solution of osgscribe looks nicer (i.e.
the wireframe color is the same of the surface but a little darker)

If I am not wrong I have to enable attribute aliasing to use osg_Normals from

You can use gl_Normals if you use a compatibility profile and no vertex

yes. You set your osg::Program with the shaders only for that part of the

The color of the walls could be texture coordinates as you says, it sounds
convincing. But, anyway, I tried adding some normals for testing with following
code but it is still not working:

HI Glen,
Thanks for posting the model. The mailing list rejects messages that are
larger than 300k so it won't have made it through to the list. I get all
bounced messages as I'm the mailing list admin. I had a quite look at the

Hi Glen,
A 100Mb file is relatively small and shouldn't normally be expected to
cause problems. However, unless you can provide stack trace or a post a
link to the model so that others can test there really won't be much we can
do to help.
