Hi,
I have come across the exact problem discussed on the forum here:
http://forum.openscenegraph.org/viewtopic.php?t=8287 which was posted May 2011.
The discussion described the problem I am seeing perfectly but unfortunately
there is no resolution posted.

Have you TRIED osgEarth?
Yes, in the past I've been working about 8 month on a osgEarth based project.
We used a 2 GB dataset, and performance was really bad until the cache is
filled.
The new project I'm starting will use dataset about to 5-20 GB, in local
storage (with some single
They are not needed at all. OSG compilation, as it is right now doesn't
support full Native compilation, it's made by calls through JNI from a
Java/Dalvik Code. The egl Context is raised in the Java part and can't be
passed down to OSG, that's the reason the examples need to use an embebed
viewer
You can use VPB-built static terrin baselayers in osgEarth, and use
osgEarth's dynamic terrain layers only where needed. You can also use
osgEarth to apply dynamic imagery sources onto static VPB terrain layers.
Hum, I've missed that in my previous project... you are probably right, it
Hi,
I've noticed that when holding information from animation channels, only gives
me the bone local position information. rotateX, rotateY and rotateZ
values are always 0.
Code as I do:
Code:
osg::ref_ptrosgAnimation::Bone actualBone =
_AnimationManager-getSkeletonBone(actualBoneName);

I recall what I did -- I actually used a crazy rendering trick to avoid
the need for holes in the terrain.
I believe you could mark the hole areas in your drape image with a

Hi Eric,
osgEarth can do everything you've mentioned you need to do. You can
add/remove layers at runtime, cut holes in the terrain using the masking
feature and run at 60 fps. When you say that performance was bad until
you've filled the cache in osgEarth, you're making a good point.
Hi,
We have an OSG-based application that uses a 3rd party library to draw video.
We want my application to perform a digital zoom on this video. Given the
API to this library, we wrote an OSG node with a draw callback that calculates
the viewport for the video to draw in, and lets the

I'm trying to upgrade a program still running on OSG 1.2.0 to OSG 2.8.3. After
some tempering I ended up getting to the point where I could compile, but after
that I've gotten stuck. The following code is throwing a segmentation fault,
and I can't figure out what I'm doing wrong:

Your 3 last plan have vertices order for a QUAD and not for TRIANGLE_STRIP,

Hi
Are you sure your quad not being rejected by depth test? Also as it being drawn
with fixed finction, modelview and projection matrices set by osg for opengl
state are affecting your quad drawing.
So easy\dirty way is to attach shader which calc vertex position without using
Hi, Mark
can you check your .osg model with 2.8.3 osgviewer? if it segfaults then it
seems like model format changed since 1.2.0 or smth along those lines.
Cheers, Sergey.

Hi, Zachary
first thing: your texture clamping setup is wrong
you should use WRAP_T instead of WRAP_R in first line
second: overlapping means that your texture coords generation provides
incorrect output, cant say much more as i have no idea what your model are

Hi Doug,
How exactly is this library drawing the video? Is it feeding the video data
into a texture, and applying that texture onto a simple quad? If so, it
seems like the best approach would be to use the osg::TexMat class to
transform the texture coordinates of the quad to simulate a zooming in
Hi,
Sergey, you wrote overlapping means that your texture coords generation
provides incorrect output.
All my texture coordinates are between 0 and 1. What kind of error would cause
an image to overlap itself multiple times like mine does?
Thank you!

Zachary

Hi,
This is a dump of how I do the mapping. I am mapping a square texture to a

Thanks for the instructions, and sorry for taking so long to respond. I had to

Oops. Ignore that last post. I forgot to also update IOS_SDK_VERSION to 5.1 in
