[osg-users] Multi-pass rendering
Hi, In my application, I have to perform the following operations: 1) render the scene into buffer A, using fixed GL pipeline 2) render the scene again into buffer B, using some shaders 3) render the scene again into the color framebuffer, using some shaders 4) superimpose (i.e. lay over) additional GL primitives over the color framebuffer, using fixed GL functionality. My question is, how to implement this sequence of operations (which have to be executed in the given order, for each frame) using OpenSceneGraph? Any hint is welcome, because I really don't know where to start and how to approach the problem. Thanks Lars. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] How to control Animation Speed?
Hi Donlin,
The osg::AnimationPathCallback has a the following methods for
controlling speed:
void setTimeOffset(double offset) { _timeOffset = offset; }
double getTimeOffset() const { return _timeOffset; }
void setTimeMultiplier(double multiplier) { _timeMultiplier =
multiplier; }
double getTimeMultiplier() const { return _timeMultiplier; }
Have a look at the osganimation example as this shows this in action.
Robert.

Hello,all
I build a model with animation in it use 3ds max,but in osg application(Load
the model .ive as a node),the animation's speed is too fast, I want use
language to set it's speed down, could anyone tell how to control Animation
Speed ?Thanks.

Re: [osg-users] Too much support!!!!!
Hi Guys, I've added the googlegroups archive to the lists of archives, alongside the existing links to gmane and mail-archive. I've also reorganised the archive links so it's right alongside the link to the list subscription rather than a separate paragraph. It's worth note the mailman archive was not linked to from the mailing lists wiki page, only the better alternatives, despite this people still on occassion use the sucky mailman archives. The saying you can lead a horse to water but you can't make it drink applies here. And there's another point. Lots of talking on this thread but actually not too much action. Who ended up fixing the wiki pages and doing the actual support rather than just talking... there is plenty done by users on support, updating the wiki, fixes bugs etc which is really appreciated, but alas what is needed is more of this community spirit, other members of the community to take on specific responsibilities. Ideally we'd have people or sets of people who could be the ones responsible for all things wiki, all things windows platform support, all things OSX support, all things unix support, all things stable release support, active server admin etc. We have lots of people doing stuff when time is available, but it remains very much on a adhoc basis. Because it's so adhoc I have to try and follow far too many topics so that I catch stuff that would otherwise fall through the cracks, I have to spread myself way too thinly with me working all hours just to keep things on an even keel. Having myself be responsible for too many aspects of the project simply isn't viable, burnout is a real issue, both physically and mentally.

this result is the world coordinate of the vertex, am I right? Can I get the

vec4 nrm=vec4(gl_Normal,0.0);

Re: [osg-users] Rendering the scene multiple times with differentshaders.
Hi Robert, I've wondering about making it possible to have a composite StateSe to provide switch and layer functionality, but have never tackled this as it complicates the basic API quite a bit for functionality that only a very small proportion of users will ever require. That being said, I do see value in having the OSG better support the type of usage you are putting it through, we just have to strive for a solution that is not intrusive to rest of the OSG. Robert. Maybe I can take a look at how to integrate this into OSG? Well, if I get time to actually do it :-) But in case I do, then I would like to try a direct integration in the OSG code-base. I will find a way to keep the old API so that any code written earlier will still work. Performance should not be affected much. I think the controller for this should be the camera, at least that is what I need, but I'd like to look closer at the code before I make up my mind. I am quite new to OSG, so I need to know where and how to submit a code contribution candidate so that it can be reviewed and hopefully approved. Who should I talk to about it? I am impressed by how quickly I got feedback on this mail thread :-) Viggo ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org _ Del personlige filer, bilder og videoer med Windows Live Messenger. http://get.live.com/nb-no/messenger/overview___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

General write access is not something I'm about to grant as the in review process I get to track what changes are being made and why. If I don't track these changes I start loose and understanding of the project. I also often modify submissions, or modify parts of the OSG in response to submissions. It's this process that keeps the coherency of the code base, it also keeps my head as coherent making it quicker and easier for me to do support because I have a good idea of exactly where the code is at. In terms of workload, if I was just the maintainer it'd be easy to keep on top of osg-submissions, so having lots of hands on this area isn't really required, it's all the other aspects to the project that currently fall on me to tackle because no one else takes stuff on. You are not the first one having this problem as the project grows - look up Linus doesn't scale for another well known instance (including some of the solutions). Not the first, and not the last by any shot, it's common to all successful open and close source projects - how do you make things scale without breaking the essence of what makes the project successful in the first place. This isn't the first time I've made a call. Roles have to stick, or to be formally passed on when people need to move on or fallback when busy at work, but there has to be a steadiness to the role that means that I can hand over the reigns and not worry about stuff being handled, and also that the community knows who to go to for certain tasks. However, this commitment isn't easy to take on. Robert. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Too much support!!!!!

I totally agree. I think there is a need for direct and clear delegation of tasks. The direct and clear delegation is key, but also a mechanism what happens with the role can't be fulfilled by the usual person responible. I can certainly step up and help in some areas if it is desired. Some parts I can help with are web/wiki administration (basic tasks) and Win32 testing/bug characterization/fixing. I think I can work out a deal with my employer for this, so that everything is clear for all parties. I'll let you know how it turns out in the coming week. Many thanks to yourself for stepping forward. Over the coming week I'll have think about what catagories of roles that are logically. I'll post this on the wiki. Ackk... solving support requires doing even more work... isn't it always the way... ;-) Robert. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Rendering the scene multiple times with differentshaders.

Well, if I get time to actually do it :-) You have the itch, you just need to scratch it :-) But in case I do, then I would like to try a direct integration in the OSG code-base. I will find a way to keep the old API so that any code written earlier will still work. Performance should not be affected much. I think the controller for this should be the camera, at least that is what I need, but I'd like to look closer at the code before I make up my mind. I am quite new to OSG, so I need to know where and how to submit a code contribution candidate so that it can be reviewed and hopefully approved. Who should I talk to about it? Us - osg-users community, we are all users/developers here! Basically the first step has already been taken by running the issue by osg-users. My own way to tackle the particular take would be to write an example that illustrates the problem that you are trying to solve, with actual scene graph code that you currently require albiet awkward and combersome, then perhaps some psuedo code about what might be possible. Then you try to modify the core in a way that is a non intrusive as you can make it, but while make the scene graph solving your problem easier and more efficient. You can throw out what you have to the community at any stage of the game, the earlier the better really as others like myself can probably point things in the right direction or chip in with some work.

Re: [osg-users] Bug in version 2.5.0 (PNG alfa)
El Miércoles 21 Mayo 2008ES 13:05:58 GMD GammerMaxyandex.ru escribió: When I upgrad version of OSG from 2.4 to version 2.5 I get some problems with PNG images. When I use PNG image with opacity in my scene on version 2.5 image disappeared but on v2.4 it looks correct (with normal opacity). I build sources of v2.5 on VS2005(and I tryed compile them under VS2008) using last dependencies it needs. OS is Windows XP SP2. For tests I used the same scene for v2.4 and v2.5. Hi, are you loading the png images directly or loading them as textures of a complete scene? If you are loading a scene, in which format is it? I load PNG image as texture of complete scene. Scene is loaded in .osg format (it exported from 3dsmax9 using plugin [osgExp]). ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Multi-pass rendering
Robert, I'll start with the samples you mentioned. Thanks, Lars Hi Lars, The OSG support multi-pass, multi-stage rendering pretty thoroughly. There are plenty of examples that use various combinations of multi-pass. For starters have a look at the osgprerender, osgprerendercubemap, osgdistortion and osghud examples.
