[osg-users] Dependencies links are dead
Hi, The dependencies "links" are dead for VisualStudio 2013. I tried both the small and full and get an invalid page. page with links: http://www.openscenegraph.org/index.php/download-section/dependencies dead pages: http://download.osgvisual.org/3rdParty_VS2013_v120_x86_x64_V9_small.7z http://download.osgvisual.org/3rdParty_VS2013_v120_x86_x64_V9_full.7z I think the other links are dead too. anyone?

Re: [osg-users] [forum] osgAnimation with bvh and model
Hi, I got a little further with the bvh problem. I know have a valid bvh file from daz3d... it appears that daz3d needs to bake the keys into it's timeline before exporting. I can now successfully load the bvh file with the option solids and see the animation working. So, now I'm stuck on the part that should animate the model. No animation going on here. This is my basic procedure: 1. I load the bvh, let's call that nodeBvh 2. I load the model, let's cal lthat nodeModel 3. I location the osgAnimation::Animation in the nodeBvh, let's call that nodeAnim 4. I create a new BasicAnimationManager (let's call that bamCallback) and register nodeAnim and call buildTargetReferrence 5. I create a group and this group gets a setUpdateCallback with bamCallback 6. I add the model to the group note the model contains skeleton and riggeometry. so am I missing a point? Thank you!

Re: [osg-users] [forum] osgAnimation with bvh and model
Hi,
I'm not giving up on this (but I'm sure am tired of failing).
I can see that that the bvh reader actually plays the animation and I can add
the option solids to the loader... this basically should show the bvh file
animating which it doesn't:
Code:
osg::Node* createScene()
{
osgDB::ReaderWriter::Options* o = new osgDB::ReaderWriter::Options;
o-setOptionString( solids );
osg::Node* bvh = osgDB::readNodeFile( osgDB::findDataFile( test.bvh
), o );
return bvh;
}
Something is just not right here... the poor documentation makes this even
harder to figure out? I'm starting to think that the bvh reader is the problem.
Thank you!
Cheers,
Peter

Re: [osg-users] [forum] osgAnimation with bvh and model
Hi Sebastian Messerschmidt, Thanks for your info. it is correct that the model containing the geometry does not have the animation,.. this is as designed. the bvh file contains the animation but no geometry also as designed. I don't want geometry and animation in the same files, because I will have 100's of bvh files that all use one character geometry. What I want is the ability to play what I want and blend what I want. back to the subject at hand... I found out that the bvh file I have does not work well with openscenegraph, this file was exported from Daz3D. I exported a bvh file from 3dsmax and I got the animation to work (somewhat). apparently there are many variations of the bvh files and openscenegraph only supports a subset of these. How I'm going to fix this is a good question... but at least now I know where the problem is. Thank you!

Re: [osg-users] [forum] osgAnimation with bvh and model
Hi Sebastian, The bvh file should be able to play without having to rename anything. there is no name matching in there. if you supply the option solids when loading they you will see a stick figure of the bones. so why the bvh files doesn't animate is what I'm looking into now...

Re: [osg-users] [forum] osgAnimation with bvh and model
Hi,
still need help:
I have tried to look only at the bvh file now, you can see the data here:
http://osghelp.com/wp-content/uploads/2013/08/testbvh.osg
here is the code that adds a little sphere to each bone, but again when I run
this no animation. anybody!?!?
Code:
class CAddDummyObject : public osg::NodeVisitor
{
public:
CAddDummyObject() :
osg::NodeVisitor(osg::NodeVisitor::TRAVERSE_ALL_CHILDREN)
{}
void apply( osg::Node node )

0), 1.0f );
osg::ShapeDrawable* d = new osg::ShapeDrawable( shape );
osg::Geode* geodeSphere = new osg::Geode;
geodeSphere-addDrawable(d);
bone-addChild( geodeSphere );
}
traverse(node);
}
};
osg::Node* createScene()
{
osg::Node* bvh = osgDB::readNodeFile( osgDB::findDataFile( test.bvh )
);
bvh-accept( *new CAddDummyObject );
osg::ref_ptrosgAnimation::BasicAnimationManager manager =
dynamic_castosgAnimation::BasicAnimationManager*(bvh-getUpdateCallback());
osgAnimation::Animation* anim = manager-getAnimationList()[0];
anim-setPlayMode( osgAnimation::Animation::LOOP );
manager-playAnimation( anim );
return bvh;
}
Thank you!

[osg-users] [forum] osgAnimation with bvh and model
Hi,
I'm trying to animate a character with data from a bvh
I have tried a lot of different setups.. but none work. The osgAnimation seems
to have what it needs to get this working, but there isn't enough documentation
to make sense of it.
This is where I am at now:
Code:
osg::Node* createScene()
{
// convenience variables
osg::Node* bvh = osgDB::readNodeFile( osgDB::findDataFile( test.bvh )
);
osg::Node* model = osgDB::readNodeFile( osgDB::findDataFile( test.dae
) );
osgAnimation::BasicAnimationManager* manager = new
osgAnimation::BasicAnimationManager;
// get animation from bvh
osgAnimation::AnimationManagerBase* animationManager =
dynamic_castosgAnimation::AnimationManagerBase*(bvh-getUpdateCallback());
osgAnimation::Animation* anim = animationManager-getAnimationList()[0];
anim-setPlayMode( osgAnimation::Animation::LOOP );
osg::Group* group = new osg::Group;
group-setUpdateCallback( manager );
group-addChild( model );
manager-registerAnimation(anim);
manager-buildTargetReference();
manager-playAnimation( anim );
return group;
}
The BVH contains Skeleton and Bones
The Model contains Skeleton, Bones, RigGeometry
so,.. what I basically do is create my own BasicAnimationManager extract the
animation from bvh and register it.
I can see the character clearly being render, but with no animation.
Am I missing something?
Thank you!
Cheers,
Peter

Are posix API's available under Android? If so we should be able to change
the osc/CMakeLists.txt to select the non Win32 part. The part of the
osc/CMakeLists.txt of interest is:
if(WIN32)
SET(TARGET_SRC
${TARGET_SRC}
ip/win32/NetworkingUtils.cpp
ip/win32/UdpSocket.cpp
)
SET(TARGET_EXTERNAL_LIBRARIES
${TARGET_EXTERNAL_LIBRARIES};Ws2_32.lib;winmm)
ELSE()
SET(TARGET_SRC
${TARGET_SRC}
ip/posix/NetworkingUtils.cpp
ip/posix/UdpSocket.cpp
)
ENDIF()
replacing the IF(WIN32) with:
IF(WIN32 AND NOT ANDROID)
Might be sufficient, could you try this? If this works I'll check this
change into OSG-3.2 branch and svn/trunk. A quick turnaround on this will
allow me to roll this in the next release candidate that I'll be making this
afternoon.
Cheers,
Robert.

[osg-users] Polytope
Hi,
I just started to use the polytope and polytopeintersect and have some results
I did not expect.
In the code there are 3 cases that creates an osg::Box which is the cube I want
to intersect with the plane. The 3 cases have each a different solution, where
I expect them all to have the same solution which is 4 intersections. There is
a comment next to each osg::Box being created.. can someone explain to me why I
don't get 4 intersections in all cases? the only difference in each case is
that I create the box in a different location.
here is the code:

[osg-users] depthbuffer question
Hi osgUsers,
I've been trying to read some values from the DepthBuffer and I don't seem
to get what I would expect. Here is a cut down version of my code (should be
able to run):
class CTestDrawCallback : public osg::Camera::DrawCallback
{
public:
void operator()( const osg::Camera cam ) const
{
osg::Image* pTest = new osg::Image;
pTest-readPixels( 256,256,1,1, GL_DEPTH_COMPONENT, GL_FLOAT );
float f = (*(float*)pTest-data());
osg::notify(osg::ALWAYS)
f = f
std::endl;
}
};
osg::Node* CreateScene()
{
osg::Group* pGroup = new osg::Group;
osg::Geode* pGeode = new osg::Geode();
pGeode-addDrawable( new osg::ShapeDrawable( new
osg::Box(osg::Vec3(0.0f,0.0f,0.0f),2.0f) ) );
pGroup-addChild( pGeode );
return pGroup;
}
int _tmain(int argc, _TCHAR* argv[])
{
osg::ref_ptrosgViewer::Viewer rViewer;
// construct the viewer
rViewer = new osgViewer::Viewer;
// make the viewer create a 512x512 window and position it at 32, 32
rViewer-setUpViewInWindow( 32, 32, 512, 512 );
// set the scene-graph data the viewer will render
rViewer-setSceneData( CreateScene() );
rViewer-getCamera()-setPostDrawCallback( new CTestDrawCallback );
// execute main loop
return rViewer-run();
}
I get a value of 0.0642448 and this is not what I expect.
I would expect that the near and far plane are automatically computed to fit
the box, which should mean the near plane is collinear with front of the
box.. which should result with a value of 0
can someone explain to me what I'm doing wrong?
regards,
Peter Wraae Marino

To do this I decided to create a matrix that has an ortho view as follows: osg::Matrix::ortho2D( 0, viewW, viewH, 0) where viewH is bottom and top has zero This works great when drawing my gui stuff.. but when I use osgText::Text as follows: m_rText = new osgText::Text; m_rText-setAxisAlignment( osgText::Text::SCREEN ); the text is at the correct position, but is upside down. I've searched the osgText if it was possible to set the drawing direction, but couldn't find anything. is there a way to solve this? I would really like to avoid having to use a osg::Matrix::ortho2D( 0, viewW, 0, viewH ), because this would mean that all my gui components would have to compensate for the viewH and reverse direction. any suggestions?, Peter Wraae Marino -- Bellinge Gymnasterne: http://www.bellingegymnasterne.dk Power Tumbling: http://www.powertumbling.dk OSG-Help: http://osghelp.com ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] using camera for intersection
Hi osgUsers, We have created huge forests using shapefiles to preprocess textures with positions where trees should be located. Then we instance all the trees using a shader, this works very well and we can have over 10 trees without any framerate drop. Because all the trees are instanced on the GPU we have no way of using intersection, because the geometry doesn't really exist. To solve this problem we decided to use a camera as a form of intersection. By setting the camera at a certain location and pointing it in the direction you want to intersect we render the scene, but instead of rendering an image of the scene we use a shader to save the positions for everything rendered, then we do a simple inverse view matrix on the position in the texture (center position) and we have a collision hitpoint in world coordinates. This works very well too, but but but because the camera is in it's own thread (multithreading) we are always a frame or two out of sync. So this is not a good solution for realtime :( we could of course change to single threaded,,.. by why? Is there another method of intersecting with instanced geometry in the GPU? any suggestions, anyone, regards, Peter Wraae Marino -- Bellinge Gymnasterne: http://www.bellingegymnasterne.dk Power Tumbling: http://www.powertumbling.dk OSG-Help: http://osghelp.com http://code.google.com/p/sigmaosg/ ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] using camera for intersection
Hi Robert, I could use the osgUtil::Intersector and create a relationship to the texture (that contains the positions of the trees) and do some kind of lookup. This would give me a rough estimation if there is a intersection. If I want to test between two branches on the same tree then there should be no intersection with that tree but with whatever is behind it. The camera method solves this problem. I have attached an image to clarify how the trees are rendered.. They are quads with images of the trees and we need to intersect with the tree and not the quad. regards, Peter On Tue, Jun 22, 2010 at 10:34 AM, Robert Osfield robert.osfi...@gmail.comwrote: Hi Peter, I would use a custom osgUtil::Intersector/IntersectionVisitor that knows about your custom use of osg::Geometry and do all the work on the CPU. Using the GPU for intersections requires a round trip to the GPU which is very expensive which will totally dominate the actual cost of the intersection. Robert.

Re: [osg-users] osg::TextureCubeMap and HDR
Hi Robert, two additions... 1. the hdr values also get destroyed by texturecubemap if you allow the default texture filter to be used. I had to change this to osg::Texture::Linear or else texturecubemap creates mipmaps and rescale the texture and destroys the hdr values. 2. it seems that texture2D has by default not to make mipmaps and texturecubemap by default makes them??? which makes things a little confusing. hope this helps, Peter Wraae Marino On Tue, Jan 12, 2010 at 11:07 AM, Peter Wraae Marino osgh...@gmail.com wrote: Hi Robert, yes.. just completed the test now.. and using squared hdr textures does work. regards, Peter Wraae Marino On Tue, Jan 12, 2010 at 10:06 AM, Robert Osfield robert.osfi...@gmail.com wrote: Hi Peter, The scaling is done with glu and it probably doesn't support the all new float formats so this may well be the issue.

[osg-users] Trees, Grass and Shadows
Hi osgUsers, I have question about rendering shadows on grass billboards. This is not a question about anything missing or not working in OpenSceneGraph, but a question how to solve a problem with shadows and grass. The problem is the grass are created using a shader that creates billboard instances, so all grass you see in the video are billboards. When the shadowmap is applied to the grass billboard I get streaks at certain camera angles. Does anyone know how to fix this problem so the grass looks more natural on a grass billboard.

Re: [osg-users] texture to file
Hi osgUsers,
I'm still battling with the luminance texture to file.
The problem is I need to save a texture with 32bit floating point
value for each pixel in the texture
as a file and load it in at a later time. (16bit can also be used if
32bit isn't supported).
I have tried all these combinations:
m_rImage = new osg::Image;
//m_rImage-allocateImage( 1024, 1024, 1, GL_LUMINANCE, GL_BYTE );
// fails
//m_rImage-allocateImage( 1024, 1024, 8, GL_LUMINANCE, GL_BYTE );
// fails
//m_rImage-allocateImage( 1024, 1024, 24, GL_LUMINANCE, GL_BYTE );
// fails
//m_rImage-allocateImage( 1024, 1024, 16, GL_LUMINANCE, GL_FLOAT );// fails
//m_rImage-allocateImage( 1024, 1024, 32, GL_LUMINANCE, GL_FLOAT );// fails
//m_rImage-allocateImage( 1024, 1024, 24, GL_LUMINANCE, GL_4_BYTES
); // fails with crash
//m_rImage-allocateImage( 1024, 1024, 24, GL_RGB, GL_BYTE );
//
works ( image 8bit in each RGB )
//m_rImage-allocateImage( 1024, 1024, 24, GL_RGB, GL_FLOAT );
//
works ( image 8bit in each RGB ), but all values zero
//m_rImage-allocateImage( 1024, 1024, 24, GL_RGB, GL_4_BYTES );
//

//m_rImage-allocateImage( 1024, 1024, 32, GL_RED, GL_FLOAT );
//
works, but fails when writing image to file
the only one that gave anykind of result was the GL_RGB, GL_BYTE ...

Re: [osg-users] texture to file
Hi jp,
If I was to post the entire render setup it would be so big.. but I'll
try and break it up into pseudo form:
-osg::Camera setSourceType GL_FLOAT
-osg::Camera setInternalFormat GL_LUMINANCE32F_ARB
-osg::Camera detaches osg::Camera::COLOR_BUFFER
-osg::Camera attaches osg:::Camera::COLOR_BUFFER with osg::Image
-the RTT uses the above camera to render an image
-use osgDB::writeImageFile using image as input and file test.png
png supports 16bit grayscale
hope this helps,
Peter

It turns out that geomA did not use the method setColorBinding at all but of course geomB did. So this brought up a question we need answered: Q: When we looked at the enum values possible we found that there is a BIND_OFF, is this the default value if not specified? and does this mean that the geom will use the last binding value used from the last rendered geom? -- Regards, Peter Wraae Marino www.osghelp.com - OpenSceneGraph support site ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi users, We are having some troubles setting the osg::TexMat relative to the current camera position. The problem arises when we have multiple cameras. We have for example a main camera and a RTT camera. We tried to use the setCullCallback expecting that before the object that uses the texture is drawn we could modify the osg::TexMat,... but... it appears that following is what happens (when running single threaded): -Camera Main: cull callback -Camera RTT: cull callback -Draw -Draw what we would like to have happen is -Camera Main: cull callback -Draw -Camera RTT: cull callback -Draw Apparently (of course we assuming here) this is how osg is designed. Can someone tells us if we understand this correctly now? and if someone has an idea how to solve this would be much appreciated. -- Regards, Peter Wraae Marino www.osghelp.com - OpenSceneGraph support site ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] Using slave cameras for composite rendering (part II)
Hi users, I have create a little test code here: http://www.osghelp.com/downloads/SlaveCameras.txt basically I add two slave games the application runs and the view is doing what I expect but I get the following messags: The interface is unknown. A null context handle was passed from the client to the host during a remote procedure call. The binding handle is invalid. anyone know what's wrong? also an added note: if I addSlave twice and try to remove them then the application is unstable and crashes. seems to be something broken here? anyone? -- Regards, Peter Wraae Marino www.osghelp.com - OpenSceneGraph support site ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] GraphicsContext
Hi users,
In our attempt to make a composite view using slave camera.. we have
had some succes but also failure.
Biggest problem is getting the render order of the cameras to work.
We tried adding them in the correct order, but we needed to use
the removeSlave (which seems to be broken)
Now we tried to use the GraphicsContext render order, but had a problem
that they did not sort correctly.
looking into the code:
struct CameraRenderOrderSortOp
{
inline bool operator() (const Camera* lhs,const Camera* rhs) const
{
if (lhs-getRenderOrder()rhs-getRenderOrder()) return true;
if (rhs-getRenderOrder()lhs-getRenderOrder()) return false;
return lhs-getRenderOrderNum()lhs-getRenderOrderNum();
}
};
if you notice the last line, it is using lhs for both getRenderOrderNum()
which will result in a constant return false value. I believe this is a bug,
correct me if I'm wrong.

Re: [osg-users] composite view and cameras question
Hi Robert, To answer the question about the two views, i'll have to explain the problem that made us to use the two views. We have a terrain and an airplane... the problem is the terrain has a lot of decals and was giving z-fighting problems. The terrain is generated by a 3rd party software so we are limited in adding anykind of bias to the decals or objects causing the z-problem. To solve this problem we decided to render the plane in one we and the terrain in another. This way the near-far plane is shorter for each view allowing us greater z precision. The z fighting problem disappeared and we are happy, but we never really did find an elegant way of syncing the two cameras. Perhaps there is a better solution to this problem, if so I would love to hear it. We talked about using slave cameras to solve the problem, don't know if this is the way but I was going to do some testing with it tommorow. You last suggestion about copying all view setting is also something we have talked about, but again before taking that direction I wanted to hear if there was an elegant way instead of the more hacked way of doing it. regards, Peter Wraae Marino On Tue, Nov 4, 2008 at 3:52 PM, Robert Osfield [EMAIL PROTECTED]wrote: Hi Peter, On Tue, Nov 4, 2008 at 2:21 PM, Peter Wraae Marino [EMAIL PROTECTED] wrote: when having a composite view I have two camera, one for each view.

I do wonder if a single View with two slave Cameras might not be more suitable. If you do have two different View's such as with two different scene graphs then perhaps sharing a single CameraManipulator between the two views might do the trick - I've never tried this though so odd things might happen. The other approach would be to attach a CameraManipulator to one View, then on each frame copy the first view's Camera settings to the second View. You'd need to break the viewer.frame() up into it's parts so you could do the sync just before the call to renderingTraversals().

Re: [osg-users] Is it possible to know when the node-graph is 'dirty'?
Hi Viggo,
This is only a suggestion (you may have other reasons). To avoid the human
error as you called it, meaning that if someone forgets to call the reformat
code...
then you should have a method that 3rd party code/humans must use when
adding to your scene, for example
void CMySceneManagerThingy::AddToScene( osg::Node* pNode )
{
// add to wherever you want the pNode to be added in the scene
code here
// reformat your scene as you want
code here
}
on the other subject about rendering multitimes the same object.. you should
just create a new group and add your objects to that group
and the group to the scene (do this as many times as you want)..
don't know why you should be messing around with the renderbins? unless you
are trying somekind of render pass?

Peter

Hi Peter,
What you say is true in most cases. The 'simplest' way to do this would be
to tell my system that the node-tree need re-formatting each time we call

humans to remember to implement both calls. This opens for human errors,
which at least I dont want (I am lazy).
I want to make my module (the one that need to format the node-masks)
independent of the rest of the system, and to ensure that the rest of the
system will not need to know about my module.
I also want to be able to add 3rd party libraries to my application without
re-writing them to do special calls to my module when they add nodes to the

to format the node-masks.
The osg::Group has a callback function named osg::Group::childInserted.
I can make my root-node into a sub-class og osg::Group where I implement
the childInserted function. This way I will get a callback each time someone
add nodes to my root-node. If a module create it's own osg::Group and add
children to it dymically then I would not know anything about that.
I also saw Roberts reply and I agree that a dirty system on the node-tree
would be very expensive. I knew that my question was a longshot.
I am now thinking about other solutions to achieve my goal. The goal is to
render the world with 3 slave cameras. One shall render all render-bins up
to bin 9. One shall render bin 10. And the 3rd shall render bin 10 and up.
So bin 10 is rendered twice. This is to fix some glitches on transparent
polygons that intersect each other while needing to write to the
depth-buffer.
Ok, so another solution would be to force a camera to only render a certain
number of bins.
I have not seen any place in the code around camera or cull-settings that
you can specify a camera to stay within a limited range of render-bins, so I
guess this won't be as easy either?
Do you have any suggestions on how to be able to render one bin twice in
the same frame. The first and second render of the bin shall have a few
render-states set differently.

Viggo

Hi Viggo,
Don't know the details of your code, but if you are adding a sub-node then
you have code already that is called for adding the sub-node and
thereby you know when the scene-graph has been modified?

// Use offsets to create world space coordinates.
osg::Vec3 _pos = m_corner + _xoffset + _yoffset

_zoffset;
// Create and position text displaying data point value.

_text-setPosition(_pos);
_text-setAxisAlignment(osgText::Text::XZ_PLANE);

I have managed to fix it by changing the alignment setting to
REVERSE_XZ_PLANE and switching the sign of the offset coords. However I feel
this is a slight hack and wondered if there is some other 'proper' setting?

Re: [osg-users] 回复： Re: multi translucent g eometry
Hi Rick, I agree with Paul. Turn off your z-buffer. If this effect is for thrusters then you should perhaps look into additive blending instead and this should create a better effect.. the more thrusters the brighter the become. A screenshot of your problem would help a lot (if possible). regards, Peter http://osghelp.com 2008/7/14 Paul Speed [EMAIL PROTECTED]: I'm no expert in this area but have had to do some pretty weird things in the past to get transparency working right for some odd scenes... One thing you might try is to disable z-buffer writes (not tests) for the flares. Depending on your blending, this can add other types of artifacts but I think in your case they will be very subtle... versus the z-fighting you are seeing. (You will obviously want them to be drawn last just like normal transparency.) Just an idea... -Paul Rick Pingry wrote: That reminds me of an issue I have not resloved yet. Our space ships have thruster engines and I use an image map with transparency and point it back at the camera to make a pretty glow around it. (First off, is this the best way to do it? I have thought that perhaps a shader would work better, but I have not had a chance to learn about how to write shaders yet. So much to learn, so little time). Anyway, In some ships there are banks of engines, and it is pretty easy to get the problem where these transparent images intersect with each other, and you get depth sorting issues that way. I did work out a way to make these engine flare images point, rather than right at the camera, all along parallel lines with the camera's line of sight, and that helped tremendously, but you can still get in positions where the images happen to line up along the same depth, and you see some funky tearing and the like due to depth fighting. Is there a way to handle this better? Should I try to apply other bins to the different engines? What are the rules wrt that? It sounds like I need to read up on the glDepth and osg::Depth. Any other recommendations? I was running into problems rendering planet halos too. Should the halo be in front of the planet or behind it? probably the same kind of thing going on.

I still can't solve this problem:

I just loaded a simple model but the program run really slowly (in

I used osg1.2 and it run so fast, even in debug mode.
Please support me with this problem, is it because of that error?
My code is simply like this:
#include osg/PositionAttitudeTransform

Hi Ricky, ok.. i think we should have asked this first. have you updated your graphic-card driver? Peter On Wed, Jul 2, 2008 at 8:37 PM, Ricky [EMAIL PROTECTED] wrote: Thanks for your supports!

[osg-users] OpenSceneGraph Help Website
Hi users, I have tried to create some tutorials on how people can get started with OpenSceneGraph. I have open the site for registration today.. only the beginner articles are available right now. Later more advanced articles will come, but for the time being I need to get the website in usable form so it's easy to use and understand. The site is here: http://osghelp.com If some of my explanitions should be wrong, missing, too little, too much.. then I would appriciate feedback. Some might be asking the question.. www.openscenegraph.com already has many tutorials and this is correct, but I have tried to simplify most of the toturials on my site so it should be easy to use/understand. I will be updating them constantly too. I haven't gone into the linux getting started tutorials yet... will come later (sorry for linux people out there... and yes I do love linux) enjoy, Peter ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

The problem of course is that when the code was checked in it was not tested for the windows platform, and now that I finally understand how it is suppose to work there are two known issues: 1. On my setup using 2.4.8 and VS 7.1 platform the cmake fails to identify that I can use interlocked and threaded environment, and so the config files written are for single threaded, and some of my bounding variables were defined as float. 2. I suspect that cmake scripts included the *build* include for only OpenThreads and OSG (and these could build fine)... problem is that all projects dependent on either of these will also need to add the build path to search, and this triggered the why can't my application find the Config header? issues. It should be easy to fix #2 if in fact that is the intended direction (and to the best of my knowledge) it was. If these things are working properly, it should be a transparent workflow. I will certainly test this and provide feedback once the windows.h issues are resolved.

Mathias, could you take the time to enter a FAQ on the wiki regarding this? I foresee many posts when people upgrade to the latest OSG of the form: why can't my application find the Config header?. Users will need to know the following: * OSG now generates headers in the build tree. If your app links with OSG from a source/build tree, your app will now need to look for headers in multiple locations. * You can get around this by installing OSG. You can customize the install location with an OSG cmake variable. * Any other info you think is relevant. A FAQ on the wiki would be better than having people search the osg-submissions archives.

[osg-users] fog
hi users,
i have tried to create a simple example using fog. As I understand it the
start and end values define where the fog starts and ends relative to the
camera?
but
not matter what values I use it doesn't effect my rendering. I seem to
always get the same fog rendering.
can someone explain/clarifiy what I'm not understanding?
Here is the code if you need to test:
#include osg/ShapeDrawable
#include osg/fog
osg::Node* CreateScene()
{
osg::Geode* pGeode = new osg::Geode();
for ( int x=0; x10; x++ )
{
for ( int y=0; y10; y++ )
{
pGeode-addDrawable( new osg::ShapeDrawable( new
osg::Sphere(osg::Vec3(x,y,0.0f),0.3f) ) );
}
}
osg::Fog* pFog = new osg::Fog();
pFog-setMode( osg::Fog::EXP2 );
pFog-setColor( osg::Vec4( 1, 1, 1, 1) );
pFog-setStart( 5 );
pFog-setEnd( 20 );
pFog-setDensity( 0.08f );
pGeode-getOrCreateStateSet()-setAttribute( pFog, osg::StateAttribute::ON
);
pGeode-getOrCreateStateSet()-setMode( GL_FOG, osg::StateAttribute::ON );
return pGeode;
}
