Does this mean that you need OpenFlight as target format? I found OpenFlight terribly slow to load and rolled my own converter to make it paged, optimized etc., but you'll need to stick to osgb for this, as the flt-format simply does not support all features. Also I guess the OpenFlight exporter is not fully fledged, so it is more aiming to translate as much information from the scenegraph as possible, instead of being optimized towards writing a performance-optimzed flt. Another hint that I can give you, is to look which options are supported by the importer/exporter, there might be some room for optimization/faster loading. In general: If you have structured databases (e.g. more the one flight, a master, possibly some externals) optimizing per element can give you some advantages. cheers Sebastian 2 robertosfield.

Let me answer Jorge first: - I am working with the trunk (as always) - HTC Wildfire S - The options from here http://www.openscenegraph.com/index.php/documentation/platform-specifics/android/43-building-openscenegraph-for-android-3-0-2 - I have tried both, same behavior Jan, here are more questions: ...Either compile for the version 5 ABI (armeabi - which doesn't use Neon) or disable the Neon instruction set according to the instructions in the doc. how?

Hi Jan, Well, I don't want to sound too harsh, but if *you* don't have time to actually read the documentation and go through the tutorials, why do you think people on the list should have time to support you? Especially as the question above is really a FAQ issue that was addressed on the list in the past. Also basic things like actually checking why it crashed in the log and finding the stack trace are well documented in the Android SDK/NDK documentation. We have our own jobs to do as well, you know. Good question. That is the purpose of the community I guess. While back when while I was more active with this list I used to support people just because. Also, I work as freelance so I know that all the knowledge gained here or there is valuable and is worth of money. It is based on the supportive attitude I believe people from this list have. So far you get me by only two emails insights into area which is new to me and I am thankful. And I am willing to share it with all the new comers since there are some undocumented stuff or it is not clear where the specs and docs are located and this knowledge is spread among the highlanders from the community who have spent the time ( which I don't have at the moment and that was the reason for me to address the community ) and money and again, it has some commercal value as well. I think as a freelance contractor I have the understanding for all you wanned to address. Thanks again for the time you spent and the know how you shared with me - actually you helped me a lot.

If you try to run code using these instructions on a CPU that doesn't support it, Linux kernel will kill your process with an invalid instruction signal - typically either SIGBUS or SIGILL = app crashes without any messages.

Interesting is that an Ogre3D application is running with armeabi-v7a. and that was my first build based on your page .. OSG runs with no problem with the armeabi-v7a too. The idea of compiling for the older armeabi is to avoid any potential problems with the optional Neon instruction support that your hardware may not have (armeabi doesn't contain those instructions).and any other compatibility issues your CPU may have, as not all ARMs are the same. The old v. 5 armeabi is compatible with practically everything on the market, the newer v. 7 ABI works with most, but then you have to be careful about compilation switches (Neon/no Neon, optimalization, etc.) because not every chip support every optional feature in that ABI. So if you aren't sure, stick with the old armeabi.

It varies from the NDK that things are build and Eclipse version (? I am sure something behind it). With the latest NDK r8e when I build the sample it says: Fatal error: invalid -march= option: `armv5te' any clue?

Hi Jan, after some reading from web I managed to set the build (and understand some of the background and terminology) to use armeabi version 5 for all the builds. So the build should be ok, just to see why is still crashing. Progress for this day :-). And thanks to you and Jorge.

Re: [osg-users] osgAndroidExample
Ofcourse it will not render textures based on the provided shader :/ (had to read the code more carefuly). All works now after triggering the GLSL shaders. Also, got rid of the Warning: Material not supported (thanks to Raymond !). For new readers having this default problems: - remove any Texture2D and TexEnv state from the statesets after you read the model (with a visitor) - change the fragment shader to read from textures.

Re: [osg-users] Need help with switching between manual and automatic camera movement
Hi Martin,
what are you experiencing, where you see the problems? It is sort of not
stated in your email. in your first code snipped in the update I would do
this to have the matrices in the world space:
Matrixd oldMatrix = cam-getInverseViewMatrix();
.
.
cam-setViewMatrix(osg::Matrixd::inverse(newMatrix));
This should setup your matrices correctly. Also once the matrixes are in
world space then you can easelly transition from automatic to manual state
by setting the camera manipulator by matrix. I think when you add and
remove camera manipulators, it goes to your home position of the
manipulator (see CameraManipulator::setHomePosition), so you have to take
into account this as well. If you want to spin it around between two
rotations try using quaternions (from the matrix, it is getRotate()) and
slerp (quaternion method) between two different orientation. These above is
just guessing since you havn't stated your problem. Maybe the best would be
if you put your whole code into sample and post it here, someone might have
time to look and help

Hi,
In my OSG application, I am trying to implement a functionality, that
would allow me to switch between usual manual movement and an automatic one
(such as spinning on spot), but I haven't had any success yet.
My last attempt was to set an update callback to the camera, that would
spin it around, such as this:
Code:
void CameraCallback::operator()(Node* node, NodeVisitor* nv)
{
Camera * cam = static_castCamera *(node);
if(cam Settings::Instantiate()-getCameraMode() ==
CAMERA_ROTATE)
{
Matrixd oldMatrix = cam-getViewMatrix();
Matrixd cameraRotation;
cameraRotation.makeRotate(oldMatrix.getRotate());
cameraRotation.rotate(DegreesToRadians(5.0), 0, 0, 1);
Matrixd cameraTrans;
cameraTrans.makeTranslate(oldMatrix.getTrans());
Matrixd newMatrix = cameraRotation * cameraTrans;
cam-setViewMatrix(newMatrix);
}
traverse(node, nv);
}
... and then I had the viewer object registered by the class that handles
keyboard events and tried to update it accordingly:
Code:
void registerViewer(Viewer* v) { viewer = v; man =
viewer-getCameraManipulator(); }
bool KeyboardEventHandler::handle(const GUIEventAdapter ea,
GUIActionAdapter aa)
{
...
case 'n':
case 'N':
Settings::Instantiate()-ToggleCamera();
if(Settings::Instantiate()-getCameraMode() == CAMERA_MANUAL)
{
viewer-setCameraManipulator(man);
viewer-getCamera()-setAllowEventFocus(true);
}
else
{
viewer-setCameraManipulator(NULL);
viewer-getCamera()-setAllowEventFocus(false);
}
break;
...
}
Hopefully these snippets are enough for someone to explain me, what I am
doing wrong and how to do it the right way.
Thank you!
Cheers,
Martin

What is the version of your archive? It seam that the code in the repository works the best with 2.1 archives. Also, good practice is to use s3 texture compression (dxt3 and dxt5) when building the archive in TerraVista. If you can build a block and post it I can take a look what is happening Let me know Nick On Mon, Apr 22, 2013 at 9:02 AM, Daniel Krikun krikun.dan...@gmail.comwrote: Hello, I have a heavy application which uses osg viewer and a TXP terrain. After some time the application is running, LOD level of the terrain starts being switched higher and lower all the time in cycles, so one second I have trees and building being displayed and one second later - they disappear. Interesting, if I run just 2 instances of osgviewer.exe with a large TXP terrain, after some time, I achieve the same effect. I suspect, TXP loader detects low memory available and switches LOD down, then when some memory is freed due to this LOD switching, the loader switches the LOD up, the memory gets low and it continues in cycles. Any ideas? I'm running Windows XP, 32-bit, GTX 670. Both osg-2.9.8 and 3.0.1 exhibit this behaviour.

Hi Martin, these are just hints.

Re: [osg-users] switch off mouse press events
Hi Sujan, what you are describing is the normal behavior of the Trackball CameraManipulator. There are many ways how you can change processing of mouse events. Either remove the CameraManipulator (view-getCamera()-setCameraManipulator(0)) or inherit from the one CameraMainpulator that most suit your needs and override the processing of the events (handle method).

Re: [osg-users] for PAN problem
Hi Sujan,
here is how I would do it:
//Let load the model:
osg::Node* model = osgDB:: readFile();
// Create MatrixTransform on top of it
osg::MatrixTransform* mxt = new osg::MatrixTransform;
// create the scene
mxt-addChild(model);
viewer-setSceneData(mxt);
Now, having it like this, by modifying the matrix in the MatrixTransofrm,
you can move the loaded object in the scene as you are doing with
onPan(double dx, double dy), and don;t touch the view matrix
something like:
void onPan(double dx, double dy)
{
osg::MatrixTransform* mxt =
dynamic_castosg::MatrixTransform*(viewer-getSceneData());
mxt-setMatrix(osg::Matrix::translate(1000+dx, 0, 0))
}
you get the idea? Hope it helps

You don't even need to use the openflight api (is it freelebly available?). Go download the OpenFlight spec from the Presagis website (it is free) and write something that will change the texture name in the openflight texture palette. If you are after using dds instead of rgb you change only the extension in the palette. I have done this several times.

Re: [osg-users] Passing location-based data to a fragment shader
Hi Shahar,
I read this post and found it interesting. Just out of curiosity :
Each texel in the new texture, should be set based on the world location of
the corresponding texel in the current geometry texture
Are you trying to overlay a texture on top of txp archive and it should be
georeferenced? If so, there might be a different approach

Hi Shahar Kosti:
As you don't provide any exact numbers I can only guess. But usually I'd
bind one or more textures per tile of paged set.
Depending on your hardware bind of 8192x8192 textures is no problem.
Can you be a bit more specific on how big the set is?
Also for the hidden textures - I don't really get what you mean. My best
guess is, that you mean not displayed.
Therefore write a custom fragment shader and bind the data-textures
along with you diffuse or whatever textures to the stateset of the tile.
As the fragment shader is fully programmable, it is your choice what is
done with the data.

Hi Sebastian,
Sorry for my late reply, it took me some time to get the data.
One TXP I'm currently looking at, represents a 3000 km² area with texture
resolution of 5m/pixel. Some areas have better resolution, up to 10
cm/pixel. The additional metadata has similar resolution. So obviously
wouldn't fit on a single texture.
Okay, so the single TXP file represents the whole area? That's kinda hard,
I thought you have multiple tiles representing parts of your complete data
set.
Anyways, First of all, your data sets need to be aligned somehow.
Regarding your suggestions, could you elaborate on the bind one or more
textures per tile of paged set approach?
My current approach (which doesn't work), is to intercept paged nodes
using a custom ReadFileCallback, which runs a NodeVisitor. The visitor
finds all Geode objects and then the underlying geometries. I can bind a
new texture to these geometries, but I'm not sure how to set the values
correctly.
You don't really need to bind at a level this deep. Usually if the
terrain tile is loaded and represent a LOD you want to work with, you can
simple add your data texture(s) as uniform to the stateset of the tile.
Given you have a texture with the data-image called texture you can do
it this way in your callback:
osg::StateSet* state_set = node-getOrCreateStateSet();
osg::Uniform* sampler = new osg::Uniform(MyDataSamper, 2 /*texture
unit*/);
state_set-**setTextureAttribute(unit, texture
,osg::StateAttribute::ON);
state_set-addUniform(sampler)**;
With this you bind the texture to a sampler for your shader, at the
texture unit 2. Depending on how many textures are already bound you might
need to modify the unit.
In the fragment shader you can now access the texture via:
uniform sampler2D MyDataSampler
..
..
main()
{
vec2 tex_coord = gl_TexCoord[0].st;
vec4 data = texture2D(MyDataSampler, tex_coord);
}
Each texel in the new texture, should be set based on the world location
of the corresponding texel in the current geometry texture. I'm not sure
how to do that using the geometry vertex and texture coordinate indices.
I hope this is clear enough.
This is a different question. If your terrain-data already contains a base
texture (like a satellite photo), the gl_TexCoord[0] might be matching
already.
If not you might want to use texture coordinate generation in the vertex
shader to get world-space texture coordinates.
It totally depends on your data.
For a first try, I'd load a dummy texture for each tile and pass it to the
gl_FragColor in the fragment shader to see how your coordinates are.
cheers
Sebastian
Thanks for the help,
Shahar

[osg-users] OPENSCENEGRAPH_MAJOR_VERSION and OSG_MAJOR_VERSION
Hi Robert, seam like this preprocessor define was renamed over the ages. I am revisiting the txp loader and found code that is compatible with older versions of the loader (osg 1.2 from the comment from while back when). The code is comming from Presagis and suppose to be the latest updates (which I don;'t agree since work was done after to support whole earth geocentric archives which is not present in the drop :/ )., Anyway, from my experience with vis-sim some companies know to stuck with acient versions of libraries and my intention here is to keep it compatible. I dont see this check in the trunk. It is for TXPNode::traverse method, there is something like: // In the time of this change Robert mentioned the next // version will be 2.0. If not then change the condition to // mach the right versions. Up to 1.2 the following statment // needs to compile.

For the first I can make a NodeVisitor and run it in ReadFileCallback so I know when my external referenced model was paged in. How to know when it gets out? The goal is to keep a valid pointer over the lifetime of a part of the scene.
