Hi,
I want to draw a 3D curved pipe from a list of points.
I looked at osgModeling but I don't know how to do this.
Would you have an idea using osgModeling or something else?
Thank you!

Re: [osg-users] Setting camera Viewmatrix with TrackBallManipulator Matrix gives nothing but black screen
if this is your code (with all the comments) then here is what you should
do:
- forget about your osg::Camera* camera = new Camera; // there is already a
Camera attached to the View
- use view.getCamera()-setProjectionMatrixAsPerspective(45,1,1,1000);
- no need to attach any CameraManipulator if you want to set the view matrix
by your own (although that is the purpose of the CameraManipulator, to
change the view matrix - probably you do it this way when you get more
familiar with the code)
- in your loop you do
viewer.getView(0)-getCamera()-setViewMatrixAsLookAt(eye,center,up)

Animation studios might use the term Particle Systems. 1980's game programmers would probably use the term sprites, especially if their motion changed when you moved. In this case blowing off as the vehicle moved. For snow, they would be partially transparent at the edges (alpha -0 ) and darker in the middle, so that when they were pasted on top together, they would make that area of the screen go dark. Not sure about the description of rain accumulation - if it were the effect of water trickling down the window, Doing trickling raindrops would be tricky - you would definitely need a particle system with a surface threshold algorithm (marching cubes/triangles) and some surface tension physics to generate the geometry to do refraction. On the inside of the window, you'd want condensation effects - that would just be partially transparent gray.

Probably my sun and the other light is both assigned as light0, so this may be the cause of the overlit problem ? I think that the light 0 is used as a skylight/headlight attached to the camera. So if you want to use that light, you have to turn the default light off. I dont have any lights other then mSun, but i see that in the code osgEphemeris is used. It has internal moon and sun light, so they are probably overlapping with my manual sun light ? No idea what that nodekit does - they may well define their own lights. And also, i heard that Silverlining can illuminate your scene like osgEphemeris, if so, it has also internal lights too ? How can i understand which light slots ephemeris and silverlining is using ? What do you mean by Silverlining? Did I understand the light slot concept correct ? : U can use 8 lights, and u need to assign them properly to make it work as expected ? OpenGL defines up to 8 user definable lights. Unless you set something up yourself, you get only the default skylight/headlight created by OSG, nothing else. In plain OpenGL you would have no lights at all (ergo totally dark scene). So you need to define your own lighting rig if you want the scene to be lit.

Apologies if my terminology isn't correct - I'm still learning how OSG (and graphics rendering in general) works!

Re: [osg-users] render a node last
Hi Lucie, you can add the node you want to draw last under new camera,and set the render order to big number (see Camera::setRenderOrder). You would then need to sync the new camera matrices with the main camera (probably via update callback). This is how I did it and it works -Nick On Fri, Oct 8, 2010 at 7:36 PM, Paul Martz pma...@skew-matrix.com wrote: It looks like you need to turn on backface culling for the sphere. But if you're going to draw non-convex objects, then turning off depth testing won't work, and instead you'll need to leave it enabled and clear the depth buffer before you draw the objects that must always be in front. For this you'll want to look at using nested Camera nodes.

Hi Robert,
I find some time to dig into this. And here are my observations ( I am
working with Vivien's submission, with osgviewerMFC )
I put break points in GraphicsWindowWin32.cpp:
Line: 2476
case WM_KEYDOWN:
case WM_SYSKEYDOWN :
{
int keySymbol = 0;
Line: 2451
/
case WM_CHAR :
/
{
// if event was not handled by WM_KEYDOWN then we take care
of it here
// this method gives directly the utf16 char back so just
need to add it as it is
if(!_keypresshandled)
{
// first check if key is already registered on the map
case WM_KEYDOWN/WM_SYSKEYDOWN : get its chance to handle every single key
you press, even a dead key. So, for my czech character 'č', I have to press:
SHIFT, '+', and 'c', in this order, and for each of these three I get
WM_KEYDOWN. The only difference is that when I complete this sequence, on
top of all WM_KEYDOWNs, it gets to case WM_CHAR: with my 'č'. This is how
the system is managing these events. To reflect this behavior into OSG, only
one single line needs to be added, I think, and that will fix Brad's issue
as well:
else
{
// was no special key, let WM_CHAR handle it
_keypresshandled = false;
_lastkeysymbol = keySymbol;
/* the new line
*/ getEventQueue()-keyPress(keySymbol, eventTime);
}
This was the key that was waste (being 'eaten' :) ..).
So to me it sounds that, with Vivien's submission, only the dead key +
'something' was not firing an event in osg - for the rest it should work as
before, not as Brad states above that the key events stopped work. I am
very curious what he was actually doing.
Cheers,
-Nick

Thanks for the extra input. I’m using VC80. I’ve previously hooked up
Spy++ and noticed that my window does not receive either WM_CHAR or

it doesn’t ever get a WM_CHAR. It does get WM_KEYDOWN and others. Anyway
I’ve also come across several posts online saying the CDialog is different
wrt WM_CHAR.
You’re example says differently and I haven’t tried a stripped down version
like that. I don’t want to belabor the point. The issue is essentially
fixed for me (regardless of which way we do translated / raw messages).
I guess we’ll see which direction Robert would like to take it vis-à-vis

Hi Robert,
I find some time to dig into this. And here are my observations ( I am
working with Vivien's submission, with osgviewerMFC )
I put break points in GraphicsWindowWin32.cpp:
Line: 2476
case WM_KEYDOWN:
case WM_SYSKEYDOWN :
{
int keySymbol = 0;
Line: 2451
Re: [osg-users] Keypress broken since rev 11749
okay .. that explains things. Looks like as per the latest MSDN there are
changes. Main thing it works for you though ...

Nick,
Thanks for the extra input. I’m using VC80. I’ve previously hooked up
Spy++ and noticed that my window does not receive either WM_CHAR or
WM_GETDLGCODE. In addition I tried something like what you’ve mentioned and
it doesn’t ever get a WM_CHAR. It does get WM_KEYDOWN and others. Anyway
I’ve also come across several posts online saying the CDialog is different
wrt WM_CHAR.
You’re example says differently and I haven’t tried a stripped down version
like that. I don’t want to belabor the point. The issue is essentially
fixed for me (regardless of which way we do translated / raw messages).
I guess we’ll see which direction Robert would like to take it vis-à-vis
translated/untranslated, dead keys, etc.

Nick,
According to my understanding and experience,
CDialog::PreTranslateMessage(MSG *msg) does not receive WM_CHAR messages so
I cannot do anything about that. In the MFC documentation there is a
CWnd::GetDlgCode method which tells the framework which key messages (like
WM_CHAR) your class would like to receive but again this does not work for
CDialog classes. GetDlgCode does not get called and PreTranslateMessage
does not ever get WM_CHAR. Therefore I cannot use any WM_CHAR based
mechanism with my existing CDialog based app. I can use a work around (ie
don’t rely on any WM_KEYDOWN) and use WM_KEYUP instead. I could also
investigate inserting a control on top of the dialog which would allow
receipt of WM_CHAR messages. Anyway there is apparently nothing I can do to
force WM_CHAR to work with CDialog.

Hi Brad,
Dialogs in MFC do not capture/receive the WM_CHAR message and that is why I
cannot properly pass it on to the OSG window
you could override CDialog::PreTranslateMessage( MSG* msg ) and do it the
same way is CView from the osgviewerMFC example

The GraphicsWindowWin32.cpp code had been in play for a few years without problems being reported on this topic and to get a report or new problem after merging Vivien's changes make me concerned that we may have broken more apps usage than might have fixed. Could this be the case? Or is Brad's experience unique? I think Nick's message shows that it may be Brad's app's message passing that's the cause of his problem. If the osgViewerMFC example works, and it demonstrates proper integration between OSG and MFC, and furthermore, the other OSG examples and apps that come with it work fine on Windows (when GraphicsWindowWin32 is used) then I think the changes to GraphicsWindowWin32 are OK. I'm inclined for the 2.9.9 dev release to revert the changes, and then let us discuss possible solutions. I don't think that's necessary at this point. As I said above, the changes seem fine. There may be other changes going forward, for sure, but I think the code is safe as it is. In the past we've talked about the idea of having raw key codes as well as translated keycodes in the GUIEventAdapter, would this help here? Perhaps, the raw key codes would be the keyup and keydown messages from the OS, and the translated code would be the accented character in the case dead keys were being used. Brad gave an example of a game that wants to check a given key directly, it would use the raw key codes, and a text editor/e-mail app (or osgWidget::Input) would use the translated key code. It would be a flexible solution.

Re: [osg-users] Keypress broken since rev 11749
Hi Robert, I actually like the idea of having osg working with dead keys thus being capable of handling language specific characters (you can type your text in osgWidget::Input in your natural language). I think this is very good feature, what Vivien has implemented. On the other side I totally understand you too, but Brad is the only one so far reporting issues and for me is likely he is doing something wrong (ehm ... maybe strong word, but he hasn't been replying lately so no idea if he fixed it). The OSG MFC example is a good guide how to properly implement things, and my hint is very standard and trivial, not a hack or work around. You might be right with your view on how actually Vivien implemented this new cool feature, improvements can always be done I think. Me being you , would let Vivien's work in, again I find it very cool.

I'm sure Brad's not alone in this. There might be a workaround for Brad and others to address this, but this all will require end users to come across odd regressions and then have to investigate and if they are lucky come across this or subsequent threads.

Re: [osg-users] Keypress broken since rev 11749
Hi Robert,
I find some time to dig into this. And here are my observations ( I am
working with Vivien's submission, with osgviewerMFC )
I put break points in GraphicsWindowWin32.cpp:
Line: 2476
case WM_KEYDOWN:
case WM_SYSKEYDOWN :
{
int keySymbol = 0;
Line: 2451
/
case WM_CHAR :
/
{
// if event was not handled by WM_KEYDOWN then we take care
of it here
// this method gives directly the utf16 char back so just
need to add it as it is
if(!_keypresshandled)
{
// first check if key is already registered on the map
case WM_KEYDOWN/WM_SYSKEYDOWN : get its chance to handle every single key
you press, even a dead key. So, for my czech character 'č', I have to press:
SHIFT, '+', and 'c', in this order, and for each of these three I get
WM_KEYDOWN. The only difference is that when I complete this sequence, on
top of all WM_KEYDOWNs, it gets to case WM_CHAR: with my 'č'. This is how
the system is managing these events. To reflect this behavior into OSG, only
one single line needs to be added, I think, and that will fix Brad's issue
as well:
else
{
// was no special key, let WM_CHAR handle it
_keypresshandled = false;
_lastkeysymbol = keySymbol;
/* the new line */ getEventQueue()-keyPress(keySymbol, eventTime);
}
This was the key that was waste (being 'eaten' :) ..).
So to me it sounds that, with Vivien's submission, only the dead key +
'something' was not firing an event in osg - for the rest it should work as
before, not as Brad states above that the key events stopped work. I am
very curious what he was actually doing.
Cheers,
-Nick

Hi Brad, that is what I was expecting while reading this thread, that you have the GraphicsWindowWin32 into some framework ... You need to pass the event from MFC to the window.

Re: [osg-users] [osgOcean] increase ocean view range
LOD - Level Of Detail. Obviously when you build a terrain database, you build it in few different level of details. What is close is more detailed what is further is less detailed. All of the terrain generation tools are aware of this and they build the final scene graph using LODs. They often build it as quad tree structure. So what you would need is, different representation of the ocean that will change based on the range. And that is done with LOD node. So your ocean can be polygonal for far range, and a hole for closer range (the hole will become your osgocean) The terrain tools like TerraVista, can do this easy. When you build your database, you would have vector culture (ESRI shape. etc) for your ocean. And you specify how this culture will be represented in your final terrain database. So you make it polygonal for lower LODs and a hole for the highest LOD. Then you set the range of your osgocean to be the same as your highest LOD range That is how I build the bosphores database with TerraVista. I am not very familiar with vpb (well, I used it couple of times to generate the whole earth with the blue marble dataset). You would need to see if vpb can work with vector culture. Or go with some commercial tolls, TerraVista, TerraSim ... etc. There are some contractors as well you can outsource the terrain generation to them. Maybe you explain what is your final database (also, what kind of sources you have) and we see if we can give better guidance. I expect some of the rest from the community might have faced and resolved this issue differently then me. -Nick On Tue, Aug 31, 2010 at 12:54 PM, issam boughanmi amigof...@gmail.comwrote: can you explain more in details this please ? -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=31188#31188 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Retrieve MatrixTransform of a loaded model
Hi lucie,
you do something like this
class CollectMatrixTransformNodeVisitor : public osg::NodeVisitor
{
public:
CollectMatrixTransformNodeVisitor() :
osg::NodeVisitor(osg::NodeVisitor::TRAVERSE_ALL_CHILDREN) {}
virtual void apply(osg::MatrixTransform node)
{
matrixTransforms.push_back(node);
}
std::vectorosg::MatrixTransform* matrixTransforms;
};
then
CollectMatrixTransformNodeVisitor nv;
root-accept(nv);
nv.matrixTransforms vector should have all your MatrixTransforms

In the old code I created a cross axes with size=1.5 for each axis. The ortho camera was defined as follows: camera-setProjectionMatrix(osg::Matrix::ortho2D(-1.7, 17.75, -1.7, 13.86)); Then I had to fix the resize problem as you suggested. So, on resize event I used the actual viewer width and height. Here is basically the call: camera-setProjectionMatrix(osg::Matrix::ortho2D(-axisSize, iWidth-axisSize, -axisSize, iHeight-axisSize)); but the axis size=1.5 was to small in this case and I had to increase it to 70 to be seen. Now the problem. On top of each axis an osgText to diplays the labels X, Y and Z. When an axis points towards out of the screen (more or less) the label disappears. In the previous implementation with axis size=1.5 it worked correctly. Can you please explain me why?

Hi,
Some file formats like OpenFlight can contain various data, which might not
be directly related to rendering but can be important in other contexts.
While I fully agree that the loaders can and should skip this information
when constructing the scene-graph, I would find it extremly useful to have
some callback mechanism for those skipped entities.
@Robert:
Can you think of a general concept that could be integrated into the
loader-infrastructure? My idea was to use a callback mechanism that can be
installed and registered to the loader implementation. Those callbacks would
textually tell me what kind of non-render-related data was read for which
node/geom etc.
For instance flt can contain things like surface material codes and
featured ids. I imagine having a callback functions like this:
class LoadCallback
{
virtual void customData(const std::string element_data, osg::Node node,
int data)
virtual void customData(const std::string element_data, osg::Node node,
float data)
... various overloads
}
Those could be called inside the loader:
...
_loadcallback.customData(OpenFlight::SMC, current_node, readuint(16))
...
Do you think that such extension would be general enough to be applied to
loaders? Would you mind If I try to include such concept?

Unfortunately, this does not have the desired effect. Applying an alpha value to the material for the geometry makes the entire geometry and image partially transparent. I would like to have the transparency level determined by the alpha values within my image. The image has some areas that are completely transparent and some areas that are completely opaque. The Image is a TGA image with alpha transparency. I can confirm that the transparency of the image is intact, because if I change the color of the geometry's material, I can see that color behind the image. But, my goal is to have the geometry on which the image placed be invisible so that all that is seen is the image.

Re: [osg-users] Extracting Node Names from NodePath
Hi John, the node path stores all the nodes from the root to the node containing the geometry (a Geode). In your case, if you picked node1, the nodepath will be root;PAT1;node1.

The lead node would be nodepath.back() -Nick On Wed, Jun 23, 2010 at 9:54 AM, John Galt manu9ak...@gmail.com wrote: Hi, I have my scene set up as follows: osg::Node* node1; osg::Node* node2; osg::Node* node3; I have loaded node1, node2 and node3 using readNodeFromFile function.

just see the pyramid instead.

Re: [osg-users] geometry
I think you can not mix index based geometry with non-index based geometry within one geometry (I might be wrong here! ). If you want to draw a line outside the pyramid, then attach another geometry to the geode doing just the line in a way you want. Are yo after drawing an arrow? If so, your approach will rebuild the arrow geometry for each matrix transform - change. -Nick On Wed, Jun 23, 2010 at 6:08 PM, Gianni Ambrosio ga...@vi-grade.com wrote: Thanks Nick for the code. Now I would like to understand why I must add the indices in this case since for a simple line I just need to insert the vertices in the geometry node. In fact I would like to add the line to the geometry outside of the createPyramid method, where the line is created without the use of indices, just vertices.

Re: [osg-users] geometry
Here is what I would do:
1) Create the whole arrow in one geometry including the line - by default
let say make it fixed pointing up (0,0,1). Here is your createArrow thing
that will give you the whole arrow
2) Add MatrixTransform on top of this geometry - with this, you can control
the position, direction and scale
3) Use quaternions for the arrow orientation osg::Quat
This way would not need to rebuilt it for each change
or
build the arrow completely in geometry shader - you would need to pass only
a line this way - only two vertices

OK, thanks Nick for the explanation suggestion. At first I started adding
the geometry to a geode separately but I would like to add the entire arrow
to the geode instead of adding the two parts. I mean somethig like that:
osg::Geode g;
g-addDrawable(createArrow());
osg::Geometry* createArrow()
{
// here use createPyramid() and then add the line
}
Is it possible? I dont like to do as follows:
osg::Geode g;
g-addDrawable(createPyramid());
g-addDrawable(createLine());
I mean, I would like to create the arrow as a single geometry but calling
the createPyramid() method.
