Re: [osg-users] NodeTrackerManipulator how to
Hi Allen, see osgplanets example to have a implementation of the nodeTrackerManipulator. Hope this can help. Regards, Vincent. 2009/6/18 Allen Saucier allen.sauc...@itt.com Hi, I am trying to use the nodetrackermanipulator and I am certainly doing something wrong. Does anyone know of an example on how to use this class? Here is the code that I am using to setup a node tracker manipulator to follow a node. But I can not even get the tracker to follow the node. If you know, could someone tell me what I'm missing? osgGA::NodeTrackerManipulator::TrackerMode trackerMode = osgGA::NodeTrackerManipulator::NODE_CENTER_AND_ROTATION; osgGA::NodeTrackerManipulator::RotationMode rotationMode = osgGA::NodeTrackerManipulator::TRACKBALL; osg::ref_ptr osgGA::NodeTrackerManipulator tm = new osgGA::NodeTrackerManipulator; tm-setTrackerMode(trackerMode); tm-setRotationMode(rotationMode); tm-setMinimumDistance(50.0); tm-setTrackNode(p_pognNodeToFollow); tm-setHomePosition(p_ov3dEye, p_ov3dFocus, p_ov3dUp, false); view-setCameraManipulator(tm.get()); Thanks!! (p.s. And I've no idea why I wouldn't want the manipulator to auto calc the home position. That's just some code I found stumbling around the net. And the proper brackets are around the osgGA::NodeTrackerManipulator in the ref_ptr it's just that the brackets are interpreted so I removed them for this post.)

I must have been trying to ignore it as it's a nightmare to debug that bit of code. I'll log it, but it could take a while to find that blighter. If you disable godrays, silt and dof (basically disable all underwater effects) then go underwater, you'll see a black like at the horizon. it looks like fog is not being applied for a line of pixels at the horizon. I think this is a fogging issue, the wave tops are probably going over the fog line and exposing unfogged geometry. Shouldn't be too bad that one. Cheers all. Kim.

Re: [osg-users] How to test for anti-alias support
Hi Alex, What OS, Hardware, drivers are you using? Robert.

I tried to have it set the number of multi samples and then call realize() on the viewer and if it failed to realize I have it try a smaller value for number of samples. What ends up happening is that it starts at 8, fails, then tries 4, which I know is supported by my video card so it should work and it appears to work, but the window opens and it is just black and nothing seems to render to it.

[osg-users] Impostor, Billboard Cloud, saving Texture to File
Hey OSG Community :)
I am coding an algorithm based on billboard clouds described in this article
http://www.cs.auckland.ac.nz/~novins/Publications/Huang04.pdf but I have some
problems for managing the creation of texture files.
I have read to osghud, osgprerender and osgsim::impostor code. I am able to
create my own impostor thanks to a camera in Ortho2D mode and FBO to a texture
2D renderered on a quad.
Code:
//Initialisation of camera with alpha
osg::Camera* camera = new osg::Camera;
camera-setClearColor(osg::Vec4(1.0f,0.0f,0.0f,0.0f));
camera-setClearMask(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
const osg::BoundingSphere bs = myModel-getBound();
//Creating texture
osg::Texture2D * texture = new osg::Texture2D;
float textureWidth = 1024;
float textureHeight = 1024;
texture-setTextureSize(textureWidth, textureHeight);
texture-setInternalFormat(GL_RGBA);
texture-setFilter(osg::Texture2D::MIN_FILTER,osg::Texture2D::LINEAR);
texture-setFilter(osg::Texture2D::MAG_FILTER,osg::Texture2D::LINEAR);
//Creating quad geometry
osg::Geometry * polyGeom = CreateQuadGeometry(myModel);
//Linking texture with geometry
osg::StateSet* stateset = polyGeom-getOrCreateStateSet();
stateset-setTextureAttributeAndModes(0, texture ,osg::StateAttribute::ON);
//Creating the geode and adding my quad
osg::Geode* geode = new osg::Geode();
geode-addDrawable(polyGeom);
//Adding group with my geode and camera
osg::Group * parent = new osg::Group;
parent-addChild(geode);
parent-addChild(camera);
//Configuring Ortho projection and FBO for camera
camera-setProjectionMatrixAsOrtho2D(-bs.radius(),bs.radius(),-bs.radius(),bs.radius());
camera-setReferenceFrame(osg::Transform::ABSOLUTE_RF);
camera-setViewMatrixAsLookAt(bs.center()-osg::Vec3(0.0f,1.0f,0.0f)*bs.radius(),bs.center(),osg::Vec3(0.0f,0.0f,1.0f));
camera-setViewport(0,0,textureWidth,textureHeight);
camera-setRenderOrder(osg::Camera::PRE_RENDER);
camera-setRenderTargetImplementation(osg::Camera::FRAME_BUFFER_OBJECT);
//Adding the model to RTT
camera-addChild(myModel);
camera-attach(osg::Camera::COLOR_BUFFER, texture);
//Adding a callback for export
TextureSavingCallback * myTSC = new TextureSavingCallback(myfile.png,
camera);
camera-setFinalDrawCallback(myTSC);
Now I want to save my model (quad+texture) into an obj file.
So basically I said to myself :
- Create an Image during a Callback
- Allocate it with Image::allocateImage
- Save the texture into with Image::readImageFromCurrentTexture
- Save Image thanks to osgDB
Code:
if (viewport _image.valid())
{
_image-allocateImage(int(viewport-width()),
int(viewport-height()), 1, GL_RGBA, GL_FLOAT);
//Here image-readPixels works fine since I have something in my image
after
_image-readImageFromCurrentTexture(0,false,GL_FLOAT);
osgDB::writeImageFile(*_image, _filename);
And after reload the texture and apply it to the quad for saving into OBJ with
OSGDB.
As you will guess it doesn't work and I only have the allocating output into my
image.
Do you have any idea of how I can handle this ?
Thank you!
Cheers,
Benoît

[osg-users] best DCC workfow using Maya and OSG
Dear OSG users, I just would like to have your feeling on what is the best way to work with 3D content using Maya (2009) and OSG (2.8.1)... I was working on old big project based on Maya 6 ang OSG 1.2, using flt export plugin from Maya and osgconv for .osg output. And then used bad home made tools to put glsl based materials on faces. I'm working now on a complete new version and want to reset the DCC workflow to something better. What I need is to export correctly geometry and hierarchy from Maya and a usable tool to assign shaders on osg models... simple isn't it ? :) What I tried for the moment : * export from maya with OBJ export plugin (ok for geometry and hierachy, no support of glsl materials of course, and bad Kd values on materials !) * using osgMaya (v0.1.1 - new version somewhere ?) that does'nt export materials but only geometry with an assigned texture... so I don't see how to manage glsl shader materials with it * more recently, my interest turns to Collada : I see that there are recent tools (I'm trying to compile it for Maya 2009) like FCollada/MayaCollada and that RenderMonkey (nice tool) can export to collada (for a lot of shaders features at least) !... So what is your feeling about all of that ? Am I going right looking at Collada ? I hoped using directly .osg and having a tool to design glsl shader but RenderMonkey doen't export .fx with glsl (any addon to do that ?) and I don't know if osg support .fx style file containing glsl shaders... I know that DCC workflow is a wide problem, but if some of you are using Maya and found a good worflow with it... :) Thanks in advance for your feedback -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=14206#14206 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi Robert, Thank you very much. regards adrian 2009/6/19 Robert Osfield robert.osfi...@gmail.com Hi Adrian, I'm afraid there is nothing I personally can to about this build issue - Windows developers who can reproduce the problem will need to look at it and solve it. The thing I'd look into first would be the roll of the CPL_STDCALL macro. I didn't write this plugin so I can't comment on why the macro is there, whether it's needed etc. As I said it'll need to be Windows developers that will have to tackle this. Good luck, Robert.

[osg-users] Dynamic line make scene disappear
Hi,
I am currently trying to build a dynamic line. I mean the extremities of the
segment can be attached to a node and change everytime the node position
relativelly to the world change. Actually, I have a NodeCullback redefined
class and a geode redefined class.
Here is the code :
Code:
void Trail::_initBefore(){
_drawable = new osg::Geometry;
_bounds = new osg::Vec3Array(2);
_color = new osg::Vec4Array(1);
osg::Vec3Array* normals = new osg::Vec3Array;
normals-push_back(osg::Vec3(0.0f,-1.0f,0.0f));
((osg::Geometry*)_drawable)-setNormalArray(normals);
((osg::Geometry*)_drawable)-setNormalBinding(osg::Geometry::BIND_OVERALL);
((osg::Geometry*)_drawable)-setVertexArray(_bounds);
((osg::Geometry*)_drawable)-setColorBinding(osg::Geometry::BIND_OVERALL);
((osg::Geometry*)_drawable)-setColorArray(_color);
((osg::Geometry*)_drawable)-addPrimitiveSet(new
osg::DrawArrays(osg::PrimitiveSet::LINES,0,2));
_width = new osg::LineWidth(DEF_WIDTH);
((osg::Geometry*)_drawable)-getOrCreateStateSet()-setAttribute(_width,
osg::StateAttribute::ON);
((osg::Geometry*)_drawable)-getOrCreateStateSet()-setMode(GL_LIGHTING,
osg::StateAttribute::OFF);
}
void Trail::updateNode(osg::Vec3 source, osg::Vec3 target, osg::Vec3
sourceCenter, osg::Vec3 targetCenter){
(*_bounds)[0].set(source);
(*_bounds)[1].set(target);
osg::PrimitiveSet* ps = ((osg::Geometry*)_drawable)-getPrimitiveSet(0);
((osg::Geometry*)_drawable)-setPrimitiveSet(0, ps);
}
The method updateNode is called everytime one of the extremity of the segment
change of position.
My problem is that when the extremities of the segment are not on the view, the
line color change to blue and the line sometimes disappear.
I don't understand wher the problem might be.
I have the same problem with trace (a Line_Strip that follow an object). In
this case, it is worst because the entire scene disappear under some points of
view.
Here is the code (it's basically the same principle as above)
Code:
void Trace::_initBefore(){
_drawable = new osg::Geometry;
_bounds = new osg::Vec3Array;
_color = new osg::Vec4Array;
_color-push_back(osg::Vec4(1, 1, 1, 1));
((osg::Geometry*)_drawable)-setVertexArray(_bounds);
((osg::Geometry*)_drawable)-setColorArray(_color);
((osg::Geometry*)_drawable)-setColorBinding(osg::Geometry::BIND_OVERALL);
_width = new osg::LineWidth(DEF_WIDTH);
((osg::Geometry*)_drawable)-getOrCreateStateSet()-setAttribute(_width,
osg::StateAttribute::ON);

osg::DrawArrays(osg::PrimitiveSet::LINE_STRIP,0,2));
}
void Trace::updateNode(osg::Vec3 source, osg::Vec3 target, osg::Vec3
sourceCenter, osg::Vec3 targetCenter){
if(!(source == osg::Vec3() target == osg::Vec3())){
if(source != target || firstCallUpdate){
if(!firstCallUpdate){
unsigned int count = _bounds-size();
if(count = 2){
(*_bounds)[count-1] = _oldPosition;
}
else{
_bounds-push_back(_oldPosition);
_bounds-push_back(target);
}
_bounds-push_back(target);
_oldPosition = targetCenter;
}
else{
_oldPosition = targetCenter;
firstCallUpdate = false;
}
setSource(targetCenter);
osg::DrawArrays* ps =
((osg::DrawArrays*)((osg::Geometry*)_drawable)-getPrimitiveSet(0));
ps-setCount(ps-getCount() + 2);
((osg::Geometry*)_drawable)-setPrimitiveSet(0, ps);
}
}
}
I need some help !

Re: [osg-users] Impostor, Billboard Cloud, saving Texture to File
Hi,
you can attach an osg::Image directly to the camera (as you do for the
texture). OSG will then read it back for you. Have a look at
osgprerender (look at the code in the callback that access the read back
image) and osgmultiplerendertargets. Inside the callback you should be
able to save the image.

Hey OSG Community :)
I am coding an algorithm based on billboard clouds described in this article
http://www.cs.auckland.ac.nz/~novins/Publications/Huang04.pdf but I have some problems
for managing the creation of texture files.
I have read to osghud, osgprerender and osgsim::impostor code. I am able to
create my own impostor thanks to a camera in Ortho2D mode and FBO to a texture
2D renderered on a quad.
Code:
//Initialisation of camera with alpha
osg::Camera* camera = new osg::Camera;
camera-setClearColor(osg::Vec4(1.0f,0.0f,0.0f,0.0f));
camera-setClearMask(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
const osg::BoundingSphere bs = myModel-getBound();
//Creating texture
osg::Texture2D * texture = new osg::Texture2D;
float textureWidth = 1024;
float textureHeight = 1024;
texture-setTextureSize(textureWidth, textureHeight);
texture-setInternalFormat(GL_RGBA);
texture-setFilter(osg::Texture2D::MIN_FILTER,osg::Texture2D::LINEAR);
texture-setFilter(osg::Texture2D::MAG_FILTER,osg::Texture2D::LINEAR);
//Creating quad geometry
osg::Geometry * polyGeom = CreateQuadGeometry(myModel);
//Linking texture with geometry
osg::StateSet* stateset = polyGeom-getOrCreateStateSet();
stateset-setTextureAttributeAndModes(0, texture ,osg::StateAttribute::ON);
//Creating the geode and adding my quad
osg::Geode* geode = new osg::Geode();
geode-addDrawable(polyGeom);
//Adding group with my geode and camera
osg::Group * parent = new osg::Group;
parent-addChild(geode);
parent-addChild(camera);
//Configuring Ortho projection and FBO for camera
camera-setProjectionMatrixAsOrtho2D(-bs.radius(),bs.radius(),-bs.radius(),bs.radius());
camera-setReferenceFrame(osg::Transform::ABSOLUTE_RF);
camera-setViewMatrixAsLookAt(bs.center()-osg::Vec3(0.0f,1.0f,0.0f)*bs.radius(),bs.center(),osg::Vec3(0.0f,0.0f,1.0f));
camera-setViewport(0,0,textureWidth,textureHeight);
camera-setRenderOrder(osg::Camera::PRE_RENDER);
camera-setRenderTargetImplementation(osg::Camera::FRAME_BUFFER_OBJECT);
//Adding the model to RTT
camera-addChild(myModel);
camera-attach(osg::Camera::COLOR_BUFFER, texture);
//Adding a callback for export
TextureSavingCallback * myTSC = new TextureSavingCallback(myfile.png,
camera);
camera-setFinalDrawCallback(myTSC);
Now I want to save my model (quad+texture) into an obj file.
So basically I said to myself :
- Create an Image during a Callback
- Allocate it with Image::allocateImage
- Save the texture into with Image::readImageFromCurrentTexture
- Save Image thanks to osgDB
Code:
if (viewport _image.valid())
{
_image-allocateImage(int(viewport-width()),
int(viewport-height()), 1, GL_RGBA, GL_FLOAT);
//Here image-readPixels works fine since I have something in my image
after
_image-readImageFromCurrentTexture(0,false,GL_FLOAT);
osgDB::writeImageFile(*_image, _filename);
And after reload the texture and apply it to the quad for saving into OBJ with
OSGDB.
As you will guess it doesn't work and I only have the allocating output into my
image.
Do you have any idea of how I can handle this ?
Thank you!
Cheers,
Benoît

Re: [osg-users] osgOcean : Integration into existing Database /Application
Hi Kim, Thanks for the short explainations. Well first the openscenegraph motionmodel or manipluators, manager aren't working. it would be good to get similar behaviour like in application-viewer example. this would be important for integration into existing applications. I do now better understand that we need to implement own geometries for water effetc. would it be not much easier that we can append a geometry (osg file, ive file ,... ) which should be used to attach the water shaders. Say for limit we attache a xy plane with shaped borders, this would be very usefull for many terrain visualisation applications, even for osgEarth this could be once an option for the ocean. of course we have fast unlimited ocean effects but once we have a lake this would not help, right? or could it be an option to cut the lake from the terrain, then we can define the height of the ocean. i will read the papers again, and i hope i can work out some strategy and new ideas which way we should - can go for further osg integration improvments. regards adrian 2009/6/19 Kim C Bale k.b...@hull.ac.uk Hi Adrien, I'm having a slight problem understanding your questions, so I'll do my best and ask some back... Would it be possible to add a ocean geometry and attach the ocean effect, shader. if yes how should it be look like, just a plane? more complex geometry? My idea would be to add a lake surface, and two rivers with different waves, and so on. Do you mean you would like to add you own method of generating the water geometry for lakes and rivers? If so, I've tried to accommodate for additional type of geometry by providing the OceanTechnique base class. Basically osgOcean is comprised of two main parts. OceanTechnique: Which generates and animates the ocean geometry and manages any level of detail algorithms that are required. It uses osg::Geode as a base class and therefore drawables for the geometry. A class derived from this should provide a water shader. Animation is provided by adding a cull/update callback. OceanScene: Which manages the various pre and post render passes required for the effects. This also includes controlling the different types of fogging and lighting that are applied based on whether the main camera view is above or below the water surface. If you want to create your own water geometry class you'll have to inherit from OceanTechnique and then add this class to OceanScene as done with FFTOceanSurface in the example application. OceanScene will only work with one OceanTechnique so you'll have to create a new instance of OceanScene if you wish to use multiple OceanTechniques. The geometry can be as complicated or as simple as you like. If you apply the current water shader to a quad it still looks alright and maybe be suitable for some applications. These two papers provide very good explanations of generating water geometry (the first is used in FFTOceanSurface): http://graphics.ucsd.edu/courses/rendering/2005/jdewall/tessendorf.pdf http://citeseer.ist.psu.edu/cache/papers/cs/26265/http:zSzzSzwww.cs.sunysb.eduzSz~ash zSzwaterCGF.pdf/ The tricky part is the shaders. osgOcean provides a very long list of uniforms which you can make use of if you wish in custom shaders. Some must be applied locally to the OceanTechnique (see: FFTOceanSurface::initStateSet() ), and those related to the multipass rendering are inherited from the statesets within OceanScene (see: void OceanScene::init()). The shader implementation used in FFTOceanSurface can be found in the resources directory (water.frag/water.vert). If you want to use this shader for your own technique you'll have to apply it within your OceanTechnique and add the uniforms found in: FFTOceanSurface::initStateSet(). Your best bet is to look at the FFTOceanSurface class and see how it's implemented. It's not as complicated as it looks, 80% of it is to do with generating the vertex array and primitives for the geomipmapping routine which you may not need. we don't need only an unfinite ocean You can disable infinite ocean effect using: FFTOceanSurface::enableEndlessOcean(false,true); Next problem i got is that the default motion models are not working Do you mean the ocean waves aren't moving? I hope that answers your questions, otherwise I've just gone off on a very lengthy tangent :) Kim.

Re: [osg-users] osgOcean 1.0 (LGPL) Released
Hi Adrian, Kim, J-S has made a modification to the OceanTechnique base class which allows you to enable/disable animation. You’ll need to set FFTOceanSurface::startAnimation(void). I had forgotten to initialize the _isAnimating member in the ctor and copy ctor. Fixed - the default behavior is identical to before (_isAnimating = true by default). The trunk is being used for development so it may or may not work properly. I would use the release 1.0 tag, I’m misusing the definition of a tag a little since I’m adding bug fixes to it as I find them. I agree with Kim, I'm making the trunk move forward according to what we need for our project so it won't always be stable. If you want something to use in your projects use the 1.0 branch.

Re: [osg-users] PolytopeIntersector
Hi Maxime, Maxime BOUCHER schrieb: Hi, Just a question. The polytopeIntersections compute the intersections with planes or all objects in the Polytope? I mean if I draw the local intersection points will I get an empty or full shape of the polytope? The polytopeIntersector performs the intersection with the space volume defined by the polytope. So if a triangle lies completely inside the polytope (without intersecting the polytope's planes) it is still considered an intersection because it intersects the volume. I wonder because I tried a polytope with a single plane (to test), and I had a lot of points non coplanars... Yes, that is to be expected because you basically got all primitives lying in the half-space to one side of your plane. I also drawed it using intersection.localIntersectionPoint, which is the center of the primitive, isn't it? Almost ;-) No actually it is the center of all intersection-points. Say you have a triangle where two points lie inside the polytope-space and one point lies outside of this space. Than you have 2 intersection-points for the points lying inside, and 2 intersections points where the edges intersect the polytope plane(s). This gives you a total of 4 intersection points and the localIntersectionPoint is the centroid(barycenter) of those 4 points.

Re: [osg-users] [build] building OSG as static library
Thanks Robert. Just made myself some static libs on osx. I didnt try xcode but plain Unix Makefiles work like a charm. With these libs my deployable executable is only 6mb now. Very nice! @Chris I am working cross-platform. So next I am trying to build statics on ubuntu and windows. Also mingw would be nice.

Re: [osg-users] PolytopeIntersector distance and Transform
Hi again Andrew, Andrew Cunningham schrieb: Hi, I am having some problems with the distance found by the PolytopeIntersector but only when the geometry I am trying to pick has a non-null (Matrix)Transform in it's parent. The PolytopeIntersector registers that object as a 'hit', BUT the distance recorded appears to be incorrect ( the end result is I end up 'highlighting' the wrong object behind the object I want to pick). The intersection calculation works perfectly (with the transformed object) but the distance to the reference plane (used for sorting the intersections) does not accurately reflect the expected distance. Just to re-iterate this. As long as I do not try to pick a node with a transform, the sorting of the PolytopeIntersector works as expected Using the LineSegmentIntersector on the same scene does not show the issue. It correctly sorts the intersections. Any ideas? I had another look at the code and found a nasty surprise in Plane::transformProvidingInverse(). There is a call to Plane::makeUnitLength() in it which should totally screw distance results of PolytopeIntersector if you have any non-orthogonal Matrix-Transforms (i.e. scaling). Could you try commenting out this line and check if it works for you? If it does help I will think of a proper fix.

[osg-users] intersection point and the right triangle
Hello all, i use the intersectVisitor to get the intersection between a ray and a geode. It works fine and I'm very happy, because it is very comfortable. Now I have the point (vector) of intersection, but I need the triangle of the drawable what I hit. I would like calculate the barycentric coordinates of the point. With this coordinates I want to calculate the texture coordinates of my intersection point. There are a comfortable way in osg? Or have anyone a idea for a nice solution?

Hi Martin, I would recommend using the osgUtil::IntersectionVisitor rather than the osgUtil::IntersectVisitor as the later is deprecated and only kept around for backwards compatibility.

TerrainManipulator and DriveManipulators aren't compatible because the ocean surface is animated and they try to position themselves by intersecting with the surface below them, which in the case of the ocean surface, is moving up and down all the time so it creates a nasty camera juddering.

It would essentially behave like a TerrainManipulator except that it would not take elevation into account; just doing simple ray-ellipoid intersection testing instead.

I have tested this fix against the data and command line options you supplied and everything looks to be fine now. An svn update on VPB will get this fix. A word of note though, VPB svn/trunk now requires the svn/trunk version of the OSG as the new support for database patching and database revisions relies on new osgDB/DatabaseRevisions classes. This week I completed the last must have feature for VPB-1.0, so will now be looking at testing and documentation for it's 1.0 release. I'll also be making a 2.9.5 release very soon too and this may well be the version that VPB-1.0 will build against (although the official OSG version will be the up comming OSG-2.10). Robert.

I starting to think it might be because I've used degenerate triangles in the primitives. When I reach the water surface, the view is flickering until I'm completely underwater... Has someone else experience the same effect ? I think i know about this one, inside OceanScene it flips between different lighting and full screen effects when the eye position passes over the average wave height. So you're probably seeing the above water and below water effects flicking between each other if you're near the threshold. I think the only way to solve this is to force the camera down or up when it's near the threshold so that you don't see the change in effects. But I don't think it's the place of osgOcean to do that. Perhaps a shader transition could be used, I'll have a think. I was playing with all the options and I can't reproduce it any more ?! it's even really nice and realistic !! (see the pics enclosed) Great work. Thanks for the help. Kim. Thanks for your all.

[osg-users] osgOcean presentation at OSG BOF?
Hi -- I'm wondering if one of the Oceanus developers will be at SIGGRAPH, and if so, would be willing to give a 5-minute presentation/demo of Oceanus? I personally haven't had time to try it out, but it has obviously generated a lot of interest and I think it'd be a valuable addition to the scheduled BOF presentations.

[osg-users] Non-square osgParticles?
Morning all, Okay, bear with me if this seems an extremely dumb question. I'm extremely new to OSG (heck, I'm new to 3D graphics in general, I've only made it through Chapter 5 of the OpenGL red book...), and I'm basically having to learn as much as fast as I can and what might seem obvious may be moderately difficult to me... Anyway, the question is this: I'm trying to simulate a jet stream emanating from a projectile in motion (ie. jet, rocket, space shuttle, etc.). I've managed to get through setting up a ParticleEffect and attaching it to the back of a Node model and everything, and in terms of where it's placed and such it actually looks pretty good, but it's in the details I'm a little bothered. While I've been able to change the actual size of the particles, I can't seem to figure out how to change the SHAPE of the particles. I'd like to try to round them out a little. I noticed the Particle object has the function setRadius but I've changed that to all sorts of extrema and don't see any difference... changing the size range works but they're still perfect squares. Is there no way to produce round (or even just rounded edge) particles? Thanks to anyone that can offer any help...

[osg-users] osgOcean is OSG 2.6 compatible
Hi all, I just wanted to let people know that as of yesterday, the osgOcean trunk is OSG-2.6 compatible. Our framework here at work is still using OSG 2.6, and so when I integrated osgOcean into it I made the necessary changes. It might even run on earlier versions, but I can't test that.

Is there no way to produce round (or even just rounded edge) particles? Thanks to anyone that can offer any help... Particles are typically rendered as quads, just because it's efficient to do so. Generally rounded objects are expensive (in computation time) to do when you're dealing with polygonal rendering, as OpenGL and OSG do. To make the particles look round, you typically just need to apply a texture map that is transparent near the corners of the quad. I attached an example image to give you an idea what I mean. When you apply this texture to your particles, they'll look round, even though they're still being drawn as quads. --J Kris -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=14247#14247 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org inline: smoke.png___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] [build] building OSG as static library
Hi, Now I am stuck on linux (ubuntu 9.04). I was able to build OSG as static libs without a hick. When I try to run the my app I get linker problems. If I switch in the dynamic precompiled binaries from the wiki the built goes fine. I am afraid I might miss something obvious that xcode does on its own. Is there anything I need to do differently when linking to static libs as opposed dynamic libs? I guess I need to figure out somehow if my static libs are punk or if I am linking them in wrong. Here is the error I get: == ../../../addons/ofxOsg/libs/osg/lib/linux/libosg.a(BufferObject.o)||In function `__static_initialization_and_destruction_0(int, int)':| BufferObject.cpp|| undefined reference to `OpenThreads::Mutex::Mutex()'| BufferObject.cpp|| undefined reference to `OpenThreads::Mutex::~Mutex()'| ../../../addons/ofxOsg/libs/osg/lib/linux/libosg.a(Camera.o)||In function `osg::Camera::~Camera()':| Camera.cpp|| undefined reference to `OpenThreads::Mutex::~Mutex()'| Camera.cpp|| undefined reference to `OpenThreads::Mutex::~Mutex()'| ../../../addons/ofxOsg/libs/osg/lib/linux/libosg.a(Camera.o)||In function `osg::Camera::~Camera()':| Camera.cpp|| undefined reference to `OpenThreads::Mutex::~Mutex()'| Camera.cpp|| undefined reference to `OpenThreads::Mutex::~Mutex()'| (keeps on going) == Any ideas? stefan hechenberger http://linear.nortd.com -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=14263#14263 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] I can't load Released OSG library in Debug Mode.
Thanks Vincent and JS; It is interesting no-no which is seen to me odd :) It always restrict us while using created dll project which uses osg. So I have to create my own dll project in two version (debug and release) for compiling new project which uses this dll in it for possibility of beeing different compilation mode. Best Regards. 2009/6/19 Jean-Sébastien Guay jean-sebastien.g...@cm-labs.com Hello Ümit, Until now, I have been using VS2003 in all project. But we have upgraded to VS2008. I don't know why can't load released OSG in Debug mode or vice versa. It throws and std::badalloc exception while using reading some model or images by osgDB's static functions(readNode, readImageFile etc...) But same code works when working same mode. VS2008 don't let us to use this interchangeability anymore or should I set some parameters? You mean you're trying to link an app compiled in debug with an OSG lib compiled in release, or vice versa? Yeah, that's a big no-no, and it's been discussed often on this list. You need to match the debug/release across your whole project, at least since VC++ 2005. Otherwise the standard library used is different and makes different assumptions about how to allocate memory and other things. This is true for any library that is coded in C++. If the dependency contains only C code, you can use only the release version of that lib with both release and debug applications if you want. The OSG dependencies packages contain both release and debug dependencies, and CMake will choose the right one when compiling OSG. You just need to make sure you do the same thing in your own apps/projects - when compiling your project in release, link to osg.lib/osgDB.lib/... and when compiling it in debug, link to osgd.lib/osgDBd.lib/...
