[osg-users] OSG_TEXTURE_POOL_SIZE issue

2016-10-08 Thread Wojciech Lewandowski 
Hi, Robert,

I believe we encountered an issue (bug?) related to maxTexturePoolSize
handling. Our application is osgEarth + few high res overlays. We set
OSG_TEXTURE_POOL_SIZE = 350 MB. It was recommended to us as one of env vars
to let osgEarth perform optimally. Overlays are rendered as RTT cameras
(FBO + 4K x4K texture2D attachments).  Overlay textures are not refreshed
every frame. They are refreshed when some inputs change but this does not
happen every frame.  And apparently thats the problem with
maxTexturePoolSize. When we pass the texture limit and create new overlay
texture, one of currently used overlay texture GL objects gets stolen.
Suddenly new overlay uses that old GL texture object but old overlay
texture is reset, its texture object is gone and scene looks bad.

I have isolated this issue to handling of maxTexturePoolSize limit in
TextureObjectSet::takeOrGenerate(Texture* texture). I believe I understand
that this policy may work with Textures which have Images attached. Even if
such texture has its GL object reset it may allocate or reuse new one and
reload the data from Image when its applied again. But there is no such
chance for texture which was dynamically rendered in FBO (and in fact still
attached to that FBO). In our app there is a multitude of textures with
images associated. Their GL objects can be safely "borrowed" if  memory
limit is passed. But non of them is taken and unfortunately we are hit
exactly where it hurts the most: in our FBO overlays.

So my question is: Is this a bug or we missed some flag to prevent texture
from scraping in TextureObjectSet::takeOrGenerate ?

Cheers,
Wojtek Lewandowski

Hi Li,

I'm not a Windows expert so can't provide answers on Windows specific
issues like this.  My guess Windows 10 has introduced some form of
window scaling that the osgViewer isn't yet aware of so doesn't take
account of.  To resolve this issue will require a Windows 10 dev to
dive in an investigate.

Robert.

Hi,

I tested the newest code, it works perfectly, thank you very much.

Just another problem:
Under the windows 10 OS (may be other OS has the same result), when screen's 
TEXT SIZE isn't 100% (my computer's setting is 150%), the osgViewer.exe's full 
screen mode works a little odd. It just like some of the screen content is 
cutted, please see the attached screenshot picture.

Thank you!

Cheers,
Li

HI Li,

Thanks for the stack trace.  I've spotted the bug.  The
osg::Camera::setCameraThread() method was setting attempting to set
the camera thread affinity even when the thread pointer was reset to
null.

I have just checked in a fix for this.  Could you try out the OSG git
master to double check it works fine.

Thanks,
Robert.

Hi Li,

Could you post the stack trace for the crash?

Does it happen with when you run standard osgviewer?

Robert.

[osg-users] How to get points lying on a plane cutting a point cloud?

2016-10-08 Thread Simone Rapposelli 
Hi,

I have a point cloud colored by intensity values and I need to extract all the 
points lying on a defined cutting plane or, even better, all the points inside 
a defined parallelepiped.

I guess that PlaneIntersector should be the right way, but it's not clear to me 
how to use Polytope.
Moreover, I have another question: is it possible to get the color of the 
points lying on the plane?Because it seems to me that intersector returns only 
the coordinates.

Thank you!

Cheers,
Simone
