Re: [osg-users] Issue with setCompileOnNextDraw (Robert Osfield)

2019-12-05 Thread Heitbrink, David A 
I am only doing setCompileOnNextDraw, after the load of my main scene. If I do 
not do it, then I get a lot more severe hangs...however after some further 
test I ran into some complications. I have a user set option to use this or 
not. I found if the scene is larger than what can fit on the GPU, I am better 
off not doing this.

I am currently running nodes with 3-4 projectors per node, 2 video cards per 
node. Each projector runs has its own process. What I found from running a 
profiler is glGet*, caused periodic hangs, this included:  

glGetInteger64v(GL_TIMESTAMP, ); 

I setup a condition around where said line is used so it is not being run 
unless stats are enabled. So it turns out when I run without stats enabled, I 
get a lot fewer hangs...but it makes it harder to quantify without stats. I 
am doing ground based simulation, so I have pretty high optical flow rates so 
dropped frames are really noticeable. I don't really see this on my development 
machine, or not to the same degree. My deployment machines are older and are 
running multiple processes. So...problem solved.maybe? 

I am still getting 100's of :
Warning: detected OpenGL error 'invalid enumerant' at after 
stateset.compileGLObjects in GLObjectsVisitor::apply(osg::StateSet& stateset)

After setCompileOnNextDraw, and I am still concerned about these messages. I 
have not tracked down exactly what objects being compiled at the time 
are..or if it's every object for that matter. 

I was also looking at the shared state manager, I am using OSG 3.6.3. Is there 
anything in particular I should do to use this?

I am doing a setCompileOnNextDraw on each render for each camera , (I typically 
only have 1) loading my scene. 

After doing thing I am getting a large number of error messages:

Warning: detected OpenGL error 'invalid enumerant' at after 
stateset.compileGLObjects in GLObjectsVisitor::apply(osg::StateSet& stateset)

It also seems that I am getting a large number of hangs. It looks like I have 
plenty of free memory on the GPU. I am pretty sure this is from loading 
textures.

 When should you use setCompileOnNextDraw? Has any else scene this issue before?

Hi All,

Our old forum was generously created by a member of our community, but a number 
of years ago the creator/manager of the forum moved on work in an area 
unrelated to the OpenSceneGraph so the forum no longer had a maintainer, 
finally the old server that was hosting has gone too.

CompileOnNextDraw is a feature that is meant to be used sparingly such as
on start up when you are first pre compiling all new GL objects to prevent
incremental compiles from breaking frame later in the app run.

First thing you should do is remove that call and see what happens.

Do you have an idea why this line was added?

Robert.

Hi All,

Our old forum was generously created by a member of our community, but a number 
of years ago the creator/manager of the forum moved on work in an area 
unrelated to the OpenSceneGraph so the forum no longer had a maintainer, 
finally the old server that was hosting has gone too.

Previous discussions in the community didn't come up with a replacement, and as 
I don't have any expertise in this direction myself I have adopted the 
osg-users mailing list mirror on googlegroups as the forum, so now when you go 
to forum.openscenegraph you'll be redirected to:

  https://groups.google.com/forum/#!forum/osg-users

The googlegroup doesn't have a record of the membership to the old forum, and I 
don't have a record either, so to use the new googlegroup forum you'll need to 
register with it.

Alternatively, you can use the original osg-users mailing list, and posts will 
be crossed posted automatically.

Cheers,
Robert.
