[osg-users] glow
Hi Community, has anyone experimented with glow effect? I have spent some time with research and I found only implementation as image post processing that requires having your scene rendered into a frame buffer. I dont like this way though, so I am looking for some alternative.

[osg-users] PagedLod : how to change priority for some nodes
Hi all, Maybe my last question about PagedLod... I hope ;-) Starting my application, databasePager start to load thousand of PagedLod in my scene. In this list, I would like to make some PagedLods nodes being loaded before the rest of the scene. (because thousands of node take sometimes more than 1 or 2 min to load) How can I do that ?

Re: [osg-users] 2D rendering priority...
Hi,
We used this approach for rendering a 2D scene using the painters
algorithm (i.e. render back to front according to our own order
definition). I have included the most relevent code snippets. No
comments on their quality please ; ).
1) Added a 'user data' object (which contains the rendering priority) to
each of our leaves.
2) As required, we run a 'RenderPriorityVisitor' over the scene to set
the correct priorities into our user data objects.
3) Create a custom render bin and setup your 2D graph to use it:
e.g. root2DstateSet-setRenderBinDetails(0, RenderBin2D::BIN_NAME,
osg::StateSet::OVERRIDE_RENDERBIN_DETAILS);
We use OVERRIDE_RENDERBIN_DETAILS as some of the objects bellow the root
of our 2D scene are also rendered in 3D, in which case they may already
have different bin details set (e.g transparent bin).
The key bit of the custom bin is setting the sort callback. This
callback sorts the leaves based on the priority set in the 'user data'
object.
Hopefully this all makes sence. I implemented this code ~7 years ago so
there may be a neater way to do this now, but it is still working well
against the latest OSG releases.
Cheers,
Brad
Code snippets:
Custom Render Bin
/** Automatically registers the bin prototype. */

setSortCallback(new SortCallback2D());
}

Paul,
Thanks for the reply. We can have up to 57 levels of priority where each
level could have 100-200 simple geometries (i.e. circles, squares,
simple line primitives, etc.). It's very rare that all levels are on
simultaneously but those that are on, need to stack in priority relative
to every other level/group that is on. Realistically, we'll have around
10-15 levels being rendered at the same time. Hopefully this
quantity/complexity won't present a problem.
I really didn't have any reservations per se about using the RenderBin
and NodeMask mechanisms. I suspected that I needed to use them but I
wanted to ping the group just to make sure I was on the right track.
When using OSG, it's always good to have a reality check before
proceeding...:)

[osg-users] How to thange color of static Geometry using Switch and StateSet?
Hi, i am OSG newbie. and i'm working with Java project which uses JavaOSG binding by NoodleGlue. about the problem: 1. I have static Geode with one drawable (geometry to draw Icosahedron). These geodes represents some specific points (lets name it diamonds) in scene (may be more than 100). Geometry has it's own StateSet: Code: Material material = new Material(); material.setColorMode(MATERIALColorMode.AMBIENT_AND_DIFFUSE); LightModel lightModel = new LightModel(); lightModel.setTwoSided(false); StateSet stateset = new StateSet(); stateset.setMode(GL.GL_LIGHTING, STATEATTRIBUTEValues.ON_Val); stateset.setMode(GL.GL_NORMALIZE, STATEATTRIBUTEValues.ON_Val); stateset.setAttributeAndModes(material); stateset.setAttributeAndModes(lightModel); and color of it is set like this: Code: setColorArray(colors); setColorBinding(GEOMETRYAttributeBinding.BIND_PER_PRIMITIVE_SET); 2. In OSG scene i have as many Switches as visible diamonds are available. So OSG tree would look like this: Code: some ROOT switch | +--- MatrixTransform node for diamond (resizing diamond when mouse is over it) | | | +--- Switch for diamond (i would like to change diamond color there, when it is clicked by mouse) | | | +--- Geode representing the diamond +--- MatrixTransform node for diamond (resizing diamond when mouse is over it) | | | +--- Switch for diamond (i would like to change diamond color there, when it is clicked by mouse) | | | +--- Geode representing the diamond +--- MatrixTransform node for diamond (resizing diamond when mouse is over it) | | | +--- Switch for diamond (i would like to change diamond color there, when it is clicked by mouse) | | | +--- Geode representing the diamond ... 3. So all i want is to change diamond color when it is clicked by mouse. If i change color directly on Geometry, then all visible diamonds changes color after one single diamond click, because it is static. I think Switch and StateSet of it is the best place to change color. I have wrote one StateSet, but it doesn't work: Code: Material material = new Material (); material.setColorMode (MATERIALColorMode.DIFFUSE); material.setDiffuse (MATERIALFace.FRONT_AND_BACK, highlightColor); highlightStateSet.setAttributeAndModes(material, STATEATTRIBUTEValues.OVERRIDE_Val | STATEATTRIBUTEValues.ON_Val); i assume because color of Geometry is set using colors array. What i need to change to make it work? Thank you!

Re: [osg-users] clear and switch buffers
Hi JP, what I meant is, that I need to call glDrawBuffer (or setDrawBuffer in OSG) to select the buffer that I want to clear. Sorry, that I did not make it clear. The following OpenGL code example shows what I want to realize in OSG: Code: //for each frame do id = id mod 2; // Id is switched in[0, 1] glDrawBuffer(buffers[Id]); // select Buffer glClearColor( 0.1, 0.2, 0.3,0. 4); // choose color glClear(GL_COLOR_BUFFER_BIT); // apply color glDrawBuffer(buffers[2]); // select Buffer glClearColor(0, 0, 0, 0); // choose color glClear(GL_COLOR_BUFFER_BIT); // apply color id += 1; So I have 3 buffers and want to initialize 2 of them each frame with different values and also switch one of them each frame. I hope this explains my problem(s).

Re: [osg-users] How to thange color of static Geometry using Switch and StateSet?
With the situation you describe, in which the Geometry is shared, the best way to change color would be with a unique BlendColor on the MatrixTransform's StateSet. You'll need to enable blending for this, and set the blend function to reference the blend color and zero the dest color, like (GL_CONSTANT_COLOR, GL_ZERO) or something like that. (I question your use of the word static. You seem to use it as if to mean it is shared by multiple parents. This is confusing, as one of the DataVariance enums is STATIC, which means the data will not be modified.)

I have static Geode with one drawable (geometry to draw Icosahedron). These geodes represents some specific points (lets name it diamonds) in scene (may be more than 100). Geometry has it's own StateSet: Code: Material material = new Material(); material.setColorMode(MATERIALColorMode.AMBIENT_AND_DIFFUSE); LightModel lightModel = new LightModel(); lightModel.setTwoSided(false); StateSet stateset = new StateSet(); stateset.setMode(GL.GL_LIGHTING, STATEATTRIBUTEValues.ON_Val); stateset.setMode(GL.GL_NORMALIZE, STATEATTRIBUTEValues.ON_Val); stateset.setAttributeAndModes(material); stateset.setAttributeAndModes(lightModel); and color of it is set like this: Code: setColorArray(colors); setColorBinding(GEOMETRYAttributeBinding.BIND_PER_PRIMITIVE_SET); 2. In OSG scene i have as many Switches as visible diamonds are available. So OSG tree would look like this: Code: some ROOT switch | +--- MatrixTransform node for diamond (resizing diamond when mouse is over it) | | | +--- Switch for diamond (i would like to change diamond color there, when it is clicked by mouse) | | | +--- Geode representing the diamond +--- MatrixTransform node for diamond (resizing diamond when mouse is over it) | | | +--- Switch for diamond (i would like to change diamond color there, when it is clicked by mouse) | | | +--- Geode representing the diamond +--- MatrixTransform node for diamond (resizing diamond when mouse is over it) | | | +--- Switch for diamond (i would like to change diamond color there, when it is clicked by mouse) | | | +--- Geode representing the diamond ... 3. So all i want is to change diamond color when it is clicked by mouse. If i change color directly on Geometry, then all visible diamonds changes color after one single diamond click, because it is static. I think Switch and StateSet of it is the best place to change color. I have wrote one StateSet, but it doesn't work: Code: Material material = new Material (); material.setColorMode (MATERIALColorMode.DIFFUSE); material.setDiffuse (MATERIALFace.FRONT_AND_BACK, highlightColor); highlightStateSet.setAttributeAndModes(material, STATEATTRIBUTEValues.OVERRIDE_Val | STATEATTRIBUTEValues.ON_Val); i assume because color of Geometry is set using colors array. What i need to change to make it work? Thank you!

Subject: Re: [osg-users] 2D rendering priority...
Hi,
We used this approach for rendering a 2D scene using the painters
algorithm (i.e. render back to front according to our own order
definition). I have included the most relevent code snippets. No
comments on their quality please ; ).
1) Added a 'user data' object (which contains the rendering priority) to
each of our leaves.
2) As required, we run a 'RenderPriorityVisitor' over the scene to set
the correct priorities into our user data objects.
3) Create a custom render bin and setup your 2D graph to use it:
e.g. root2DstateSet-setRenderBinDetails(0, RenderBin2D::BIN_NAME,
osg::StateSet::OVERRIDE_RENDERBIN_DETAILS);
We use OVERRIDE_RENDERBIN_DETAILS as some of the objects bellow the root
of our 2D scene are also rendered in 3D, in which case they may already
have different bin details set (e.g transparent bin).
The key bit of the custom bin is setting the sort callback. This
callback sorts the leaves based on the priority set in the 'user data'
object.
Hopefully this all makes sence. I implemented this code ~7 years ago so
there may be a neater way to do this now, but it is still working well
against the latest OSG releases.
Cheers,
Brad
Code snippets:
Custom Render Bin
/** Automatically registers the bin prototype. */
static osgUtil::RegisterRenderBinProxy
s_registerBin(RenderBin2D::BIN_NAME,new RenderBin2D());
RenderBin2D() { //extends RenderBin
setSortCallback(new SortCallback2D());
}
SortCallback2D

renderBin-copyLeavesFromStateGraphListToRenderLeafList();

Paul,
Thanks for the reply. We can have up to 57 levels of priority where each
level could have 100-200 simple geometries (i.e. circles, squares,
simple line primitives, etc.). It's very rare that all levels are on
simultaneously but those that are on, need to stack in priority relative
to every other level/group that is on. Realistically, we'll have around
10-15 levels being rendered at the same time. Hopefully this
quantity/complexity won't present a problem.
I really didn't have any reservations per se about using the RenderBin
and NodeMask mechanisms. I suspected that I needed to use them but I
wanted to ping the group just to make sure I was on the right track.
When using OSG, it's always good to have a reality check before
proceeding...:)

Re: [osg-users] Problem with rotations using PositionAttitudeTransform
Hi Manuel,
You use the osg::Quat(x,y,z,w) constructor, but your arguments are not
in the good order.
You may use osg::Quat(angle, osg::vec3d(x,y,z)) to be sure.
Hope this can help you.

Vincent.

Re: [osg-users] How to change color of static Geometry using Switch and StateSet?
Andrius Kausinis wrote: Hi, Static means that Geode object is constant (static final in Java) and Data variance of this object is set to STATIC. Then I misunderstood your original post. So are you saying that the problem you are trying to solve is this: How to change the color of a static Geometry? If so, then sync the draw threads in the main loop with viewer.sync() then just go ahead and change the color array. Or is this the problem: How to have unique colors on a shared Geode/Geometry multiparented to several transforms? If so, then use my BlendColor suggestion. -Paul ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Problem with rotations using PositionAttitudeTransform
Thank you very much Vincent! That was my error, I was calling to the osg::Quad constructor with a wrong order in the params Cheers, Manuel -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=24049#24049 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Stereo with pre-split images streams
I'm about to drop OSG into an app and I'm looking at how to do various things. The built-in stereo support is great, but I'm not sure how to do something that's easy in my current code - handle pre-split images. I have to take a variety of images, mainly in streams, and handle them correctly in the left and right eye. The formats I deal with are: 1. Dual-stream, for instance two images, or two tracks in a Quicktime movie or AVI file (3D Blu-ray too, someday), 2. Left-Right, 3. Top-Bottom, 4. Possibly, interleaved. Right now I've dealt mostly with 2 3, by padding two sets of tex coords along with 3D images. I intend to deal with 1 and 4 by splitting textures, maybe using 2 FBO attachments. The issues/options seem to be: Draw the images billboarded and at screen depth, so there's no extra parallax introduced. It would be great to be able to mask or draw a frame 'in-front' of the image, even though it's at zero, so the edges appear to be at the same depth as the content (or can be manipulated). Then I can either use a cull callback, since I believe cull runs once per eye, and reset tex-coords and/or which texture (or attachment of an FBO) to use, or place a duplicate item of each 3D texture in the graph, set it correctly on update, then set the stereo cullsettings correctly. Any suggestions? Did I miss a better technique?

Re: [osg-users] node names not preserved going from flt to ive/osg
Hey all Yep -- setting OSG_OPTIMIZER to off and preserveFace and preserveObject options did the trick. thanks all!
