Hi,
I'm developing simple Android app, with two separate views using osg. Got
problem with simultaneously running these two. Whole code is based on existing
examples in osg distribution (osgAndroidExampleGLES1 and
osgAndroidExampleGLES2). Ii'm putting on layout two views (like ELGView class
Hi,
I'm using 3.2.2-rc2, building it for Android and trying to use in Qt (5.4.1)
application. OSG is configured with this:

-DDYNAMIC_OPENSCENEGRAPH=OFF -DOSG_GL1_AVAILABLE=OFF
Hi,
I'm trying to integrate shivavg library (version of openvg specification) with
my osg application. I've created new class derrived from osg::Drawable for some
openvg primitive. But trying to create this drawable causing crash. After
digging in sources, there is getting extensions list
Hi,
Me again ;). This time i would like to ask about animations, particular kind of
it. I've made animation using channels and Vec3LinearChannel type. It works
fine, without any problems, e.g. i've used three Vec3Keyframes to animate
sample translation (or rotation), object position is nice
Hi,
Searching forum i've found such topic
http://forum.openscenegraph.org/viewtopic.php?t=5758, which is quite similar to
my problem, however does not solved my issue. I'm trying to write functionality
to remove node with all subnodes, but cannot get it to work. Assign NULL to
shared pointer
Hi,
Ok, i was mislead by previous thread and setting NULL to ref_ptr. So, i'm using
removeChild, as it should be and got crash. I'm doing this in such way:
Code:
osg::ref_ptr osg::Geode geode = new osg::Geode; // on start
osg::Geode* g = geode.get(); // store pointer to my geode somewhere
Hi
I have written custom plugin to save/load my scene with custom user data. My
solution stores scene tree, but geodes are stored as paths to separate model
files (not geometry data). When scene is loaded, geodes are created using such
piece of code:
Code:
osgDB::ReaderWriter* plyReader
Hi,
Will answer by myself. This wasn't problem with plugins, just forget to set
checking z-buffer for loaded node in my plugin, so quite obvious error :/. So,
probably this thread could be deleted (if possible) as not very interesting
problem.
Thank you!

Hi,
Is it possible to force osg plugin to store user values for nodes (set by
setUserValue() method from osg::Node) somehow? Maybe using osgDB::Options, but
haven't found any solution. Or only solution to store nodes with user values is
writting separate plugin?
Thank you!

The new serializers allow you to implement your own serializers for your own

This means that i need to subclass all osg classes to have such possibility?

I've created new import/export plugin for models stored in particular format.
There are animations included, which are imported also without any problem.
However i would like to have possibility to edit such animations in my editor

I have i think a simple question. If i'm adding new objects on scene and they
are invisible (culled) or partialy invisible, how to force view or camera to
show all objects (whole scene). Is there any simple method?

I have no errors, just version using draw elements is not displayed. I'm using

I have found one interesting behaviour yet:

After deep analyze of osgTerrain code i found solution fine for me. In original

Hi,
I'm back again with my terrain editing question :). I was serching forum for
some solution, but i didn't find any. If i have found at least terraintile
geometry and drawable associated with that how i could change this geometry?

Hi Robert :),
Yes, i was investigation this sample. But there is used intersect visitor for

Thanks for advices. But i have still one question to clarify. Let's assume,
that i have simple node visitor, which traverses my terrain nodes - something
like terrain-accept( myvisitor ). It calls myvisitor::apply( osg::Geode geode
) method.
Inside i want to create intersection visitor,

Hi,
I have again basic question which is related to my previous one about terrain
editing. I can create terrain with lot of tiles, so now i want to have
posibility to choose particular tile by picking it. The way i tried to
implement is something like that:
1. create osgTerrain object
2. add
Hi,
VPB isn't really intended for editing terrain, but it generates heightfields
that can be dynamically altered at runtime just fine. You just have to be
aware that there are multiple LODs of each terrain tile.
Could you explain it with more detail? How i can alter heightfield in
Hi all,
I've created terrain using osgTerrain::Terrain, way simialr to that:
osgTerrain::Terrain* Terrain = new osgTerrain::Terrain;
osg::Image* high_map = osgDB::readImageFile( height.bmp );
osg::HeightField* heightmap1 = new osg::HeightField;
heightmap1-allocate( RES_X, RES_Y );

Problem is solved now :) and i think my way was quite right (as i presented
above). Problem was in wrong scalling of objects and manipulators. I know that

able to provide features for that? I'm not familiar with
