Re: [osg-users] Render to 3D texture example and questions
Yes, I'm running in debug mode under Windows Server 2008 with 174.74 driver and enabled Aero. NVIDIA OpenGL SDK 10 gives me a 3D texture rendering demo. This demo first bind one of the slice of 3D texture and then perform some render to update the texture. Three 128*128*128 3D texture are used, but it shows above 60 fps. What I have to do in my OSG program is to simulation the way the demo does, so I have to create 256 cameras and bind every slice to them. I think this will be a huge rendering work for GPU and also for OSG. So I'm wondering if some works can do to reduce the cameras or I have to write my special 3D texture rendering camera?

The whole issue of stale/obsolete .zip files goes away, It's really quite nice. Making .zip snapshots effectively introduces a second layer of manual version control on top of svn.

Ex: I have one svn project that consists solely of empty directories and svn:external references; w/ one svn update, a dozen completely unrelated projects are synced to their current trunk.

[osg-users] OSG 2.4 problem reading tiffs.
Hello, I am using WinXP and MSVC 8 and had a working OSG 2.2 build running. I downloaded the 2.4 zip and the new 3rd part zip, run cmake, build the default viewer applications. Running osgviewerd with full debug I see the following output. FindFileInPath(e:\Models\Earth\globe.obj): returning e:\Models\Earth\globe.obj Reading OBJ file itr='e:\Models\Earth' FindFileInPath() : trying E:\Models\Earth\globe.mtl ... FindFileInPath() : USING E:\Models\Earth\globe.mtl --globe.mtl-- --globe.mtl-- --E:\Models\Earth\globe.mtl-- Reading MTL file itr='E:\OSG\BUILD\bin' FindFileInPath() : Trying E:\OSG\BUILD\bin\osgplugins-2.4.0\osgdb_tiffd.dll ...

Still no luck reading tiff files. Anyone have any ideas on what I should check next? ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

A standard system for skeletal animation is something OSG currently lacks. There was some discussion some months back about settling on one, but that's unlikely to happen anytime soon. For now, your main option is Cal3D. However, when I'm done with osgWidget I'll probably devote that new time to helping Cedric Pinson more with AnimTK, which I really believe to be a great toolkit (though we'll have to eventually address it's usage of the GPL). I've already contributed a bit to it and can speak for it's soundness, and both myself and Cedric use Blender a great deal--so it's exporter there will be rock solid. :) I've made some videos of AnimTK mixing some simple animations from a model made in Blender, they're on the osgWidget website (because it also uses a simple osgWidget::Frame window :)) http://osgwidget.googlecode.com I can tell you this though: AnimTK is divorced from any kind of mesh format, so it wouldn't be impossible for the Collada plugin to use it to facilitate it's animation in OSG one day...

Re: [osg-users] Render to 3D texture example and questions
Quoting hesicong2006 [EMAIL PROTECTED]: I think another way should be possible: Only one RTT camera, under it there are 256 pieces of slice to render. When render Nth slice, change RTT camera's Z index to N. Is it possible to use osg::StateSet to do so? I was actually wondering whether the nvidia demo only renders one or a few cameras each frame to get to 60 Hz. What you propose makes sense but not only would you need to change the target Z slice but also aspects of the scene you're rendering. Otherwise you get the same result for each slice which is probably not what you want. Try attaching an UpdateCallback to setup the slice each frame, I don't think it can be done in the StateSet.

Re: [osg-users] problem compiling OSG2.4 on MinGW
I have compiled OSG on devcpp , and OK. I transform all .lib to .a like these steps: pexports zlib1.dll zlib1.def dlltool -k -d zlib1.def -l libzlib1.a or like these steps reimp -d libmysql.lib dlltool -k -d libmysql.def -l libmysql.a and under CMAKE,choose these .a files instead of .lib files. I hope i have explained clearly.i am poor in english.

Not by OSG. The problem with COLLADA animations (which is actually a good thing in most respects), is that you can really animate *anything* in COLLADA (from transforms to material/shader parameters), so it's quite a bit of work to get animation working in a complete way. The other constructs not supported by the OSG loader are controllers, such as skins and morph targets. If your file contains these, you won't see them either. Most of the time geometry is attached to one or more skin controllers. The bones of the skin controller are then transformed, and the transforms are animated. --J ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
