It might not have any issues with the usage case you have, but it
doesn't necessarily mean that it will work with all usage cases.

One area that broke causing problems for some users was when render to
texture was used with a Qt/OSG application.  The OSG would set/reset
OpenGL glRead/DrawBuffer state based on the values set up for the
osg::Camera.  All the src/osgViewer/config implementation correctly
set the Camera::setDrawBuffer/setReadBuffer() values for single and
double buffer windows rather than leave as defaults.

You may be able to get away with not setting the
Camera::setDrawBuffer/ReadBuffer settings if you don't use render
texture, but even then you are still leaving a bit dangerously, you
are basically running with "uninitialzed" values.

In the osgQt repo we fixed things so that the examples do correctly
set up the osg::Camera, but we can't fix 3rd party code that is living
out there in user applications, the best we can do is discuss the
issue.

Cheers,
Robert.

Re: [osg-users] osgQt + OSG 3.6.2 Status

[Mathieu MARACHE]

Hi Werner,

We share the same belief around Qt.

Concerning your implementation, it's not clear how you integrate the OpenGL
window into Qt. If you are willing to share a simple application that
demonstrates your setup that would be a nice start to understand and
discuss your approach ?

Recent versions of Qt5 use OpenGL to render many UI components and thus it
is not unfrequent to have many OpenGL context created inside an
application. It is my understanding that QOpenGLWidget and QOpenGLWindow
manage to make these OpenGL context handling transparent.
The main difference between these two is that the QOpenGLWidget is rendered
inside a ImageBuffer or something like that and that the QOpenGLWindow
mimics the Qt4's QGLWidget we were used to allowing QuadBuferring etc.. But
being a Window lots of the Widget inherited things have to be implemented
(mostly UI events).

Re: [osg-users] OpenSceneGraph-3.6.3 release candidate 2 tagged

[Robert Osfield]

HI Glenn,

We did some work for 3.6.3 to smooth the transition between glTexImage
and glTexStorage remapping to sized types where possible, perhaps this
particular image format it's not remapped properly.

The best thing to do now is create a small example/provide data to
illustrates the problem then we can work out what the short term
application fix would be and what the longer term OSG fix might be if
appropriate.

Now that 3.6.3 is tagged I'll be taking a step back from testing and
debugging on the OSG side.  If there are bugs that appear in 3.6.3
that need to be addressed I'll return to another cycle of testing,
debugging and working towards a 3.6.4 release.  I won't push for 3.6.4
for another couple of months though - I have plenty of other work to
get on with :-)

Cheers,
Robert.

Good to hear that you've completed the port.

OpenSceneGraph-3.6.3 is out now so you'll have to start all over again!

Thought this time is shouldn't be anything more than a recompile :-)

Just to let you know everything compiled and worked.

OSG-3.6.2.  He does not appear to be supporting VTP since 2015.


Thank you!

Hi All,

I would like feedback on the community about possible forum/mailing
list tools that we could adopt for the OSG and VSG projects.  I don't
have any significant experience with Gitter but have just started
looking into it - I see that osgjs has a presence.

Would love to hear what others experiences have been with Gitter or
other similar tools/services.

[osg-users] OpenSceneGraph-3.6.3 stable release has been made!

[Robert Osfield]

Hi All,

I have tagged the 3.6.3 stable release:

https://github.com/openscenegraph/OpenSceneGraph/tree/OpenSceneGraph-3.6.3

Changes since 3.6.2 in June have been mainly focused on bug and
warning fixes.  Features wise I merged the glTexStorage changes from
OSG master into 3.6.3.

One the fixes changed the API slightly so the ABI has changed albeit
in a minor way, so I've SO version number has bumped up.  This means
3.6.3 won't be a drop in replacement for 3.6.2, you'll need to
recompile your application to make sure everything is solid.

Thanks to everyone who's helped with testing and bug fixings,
Robert.

otherwise it'll have to wait till after 3.6.3.

[Voerman, L.]

I did no testing with alpha and 2d texture array combined. Normal 2d
textures with alpha seem to be working fine, both with blend and with alpha
test.

 Hi Glenn,

 I've compiled and run the example against the 3.6 branch with images
 from OpenSceneGraph-Data/Images and it runs on my Kubuntu 18.04/NVidia
 system without any obvious issue.  Could you explain what the issue
 looks like so I could specifically test it?

 Laurens Voerman has kindly investigated the issue and has a PR that
 addresses it:
https://github.com/openscenegraph/OpenSceneGraph/pull/624/files

 I want to be able to recreate the issue so that I can confirm that the
 PR fixes it - it looks like it fixes it to me but don't want to make
 any assumptions.

 Cheers,
 Robert.

Do you see these problems with 3.6.3-rc3?  Do they occur with test
program Laurens posted? Do they occur with any alpha'd image?

Robert.

HI Laurens,

Fun image demonstration of mipmapping :-)

Works fine for me with 3.6.3-rc3.

Cheers,
Robert
