[osg-users] Bounding Boxes Baked Animation
I have a scene where I'm importing an FBX with a large baked animation in it. Most of the time, it works great. However, if I set my camera to setComputeNearFarMode(osg::Camera::COMPUTE_NEAR_FAR_USING_BOUNDING_VOLUMES), then it seems the bounding box doesn't update with the animation. The bounding box seems to set to the initial position, and then it clips as soon as it moves. Any ideas how to resolve this? -- Randall Hand www.yeraze.com ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] OSG Collada
I'm having trouble with the OSG Collada plugins on Visual Studio. I tried downloading the recommended version from the website, but that now leads to a dead-end. I dug the the same Collada 2.2 download I use on Mac Linux, but I am completely unable to get CMake to recognize boost on windows, as well as getting lots of Cg header errors when using their provided solution file.

Re: [osg-users] Retrieving Z-Near Far per-frame
So... I need to attach
instead to setCullCallback?
I'm looking in ViewerBase and I see the order is event, update,
rendering, and Rendering calls "renderer-cull()". I need to be
after a completed cull, but before rendering actually starts (or at
least as early into rendering as I can get). Could/should I register
what I want as a custom "operation"? Or is this the job of the Camera's
PreDrawCallback?
Basic requirements:
* Run once per frame (in a system with multiple viewers contexts
per frame)
* After Cull (so I have a valid znear/zfar estimate for the frame), but
before/during the Render
* I will not be modifying the scenegraph, only reading data
shipping it elsewhere

Hi Randall,These
will be valid for the previous frame as the cull traversal happens after
the update traversal.

Re: [osg-users] Non-typical Stereo Usage
What I mean is that my Left Right eyes are not a trivial camera offset. I'm rendering different textures and geometry into the 2 eyes. I did some research and _think_ I can do this using masks for CullLeft and CullRight. Is it possible to have both stereo non-stereo viewers? (eg, I'll have a primary non-stereo viewer, then secondary slave-cameras connected to stereo-viewers). Mathias Buhr November 28, 2012 4:20 AM Hi Randall,the OSG already supports a couple of stereo modes. Maybe they can be ofany use? See osg::DisplaySettings::StereoModeWhat do you mean by "completely unrelated"? If it means completelyunrelated then you can just create as many viewers/scenegraphs as youlike. But I'm guessing all your views are supposed to render differentviews of the same content.If thats the case and your viewers are separate processes (or even onseparate machines) you might want to take a look at the "osgcluster"example. This example runs separate viewers synchronized through a network.In case you are running linux and want to pipe one view to the specialhardware you can set up a separate X screen and configure one of yourviewers to utilise this screen. See osg::GraphicsContext for details.Maybe you can give a bit more details on what you are trying to do.Best regardsMathias___osg-users mailing listosg-users@lists.openscenegraph.orghttp://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org Randall Hand November 27, 2012 10:43 AM I need to write an application to use Stereo support (120hz, quadbuffered 60hz) to render stuff out to a display, but it's not yourtypical left-right stereo.

Hi, I've been programming in OpenGL for several years now, and I'm about to start a new project and thought OpenSG might be a good tool to use. However, I'm integrating data from lots of outside sources (gyros, cameras, network, etc) so I can't just do a Viewer run() (looking at doing the Viewer frame() thing), but I'm also going to have lots of frequently changing geometry camera information. All the demos I see simply construct a Scenegraph once at program start, then do Viewer run(). Is it possible/advisable to have frequently changing scenegraphs with OpenSG (eg, new nodes, dying nodes, changing nodes, etc). ... Thank you!

Re: [osg-users] Binding Multiple COLOR_BUFFERn's to a FRAME_BUFFER_OBJECT ?
Ok, I updated my code to
just use 2 textures attached to the camera (COLOR_BUFFER and
DEPTH_BUFFER), and a fragment shader to set gl_FragColor.xyz =
texture(depth).aaa , and that seems to work when I set my implementation
to FRAME_BUFFER_OBJECT.
However, I had to add another slave camera to the view to display the
Color channel (same as above, but no fragment shader). This works too,
and is in fact what I wanted to do (later on, I'l be distorting these
images so a simple screen-quad won't be the actual use). However, I
have a "random noise" window that's the default camera. I set
windowDecorations and such to false, but it's still there (hidden behind
my other camera displays). Is there any way to hide it? I tried
setting pbuffer=true on that gc, but then the whole app dies (I get
blank textures everywhere).

Re: [osg-users] Multiple Buffers on Multiple viewers
Just updating the status..
I finally figured this out, about 2am after several more attempts.
Basically, I learned that OpenSceneGraph isn't "magic" and simply
traverses the graph in order, so I had to be a bit more careful about
the order that I did things like constructing GC's, assigning viewports,
and attaching to the main graph.
Also, I finally learned how to use osgViewer::Viewer andm
osgViewer::CompositeViewer effectively.. Tu rns out I didn't need a
Composite Viewer, I could get my same functionality with multiple
contexts/viewports in a single Viewer.. and it's simpler, faster, and
less error-prone.
Liking OSG so far.. Bit of a learning curve from basic OpenGL, but not
as bad as I thought once I quit expected it to do magic things for me :)

I've done this in raw
OpenGL before, but I can't for the life of me getit working in
OpenSceneGraph. I need to render a scene and then displaythe result
in 2 separate windows: One showing the Color Buffer, oneSHowing the
Depth Buffer (and eventually a 3rd showing the STencilBuffer).
I've tried all day and got varying results, but nothingapproaching
success. CAn someone tell me what I'm doing wrong?Relevant code
below.. Don't laugh too hard, I've been googling andreading the
examples and cut-n-pasting code snippets all day, and I'mrelatively
sure that at least 50% of this is unnecessary.. Right nowit's in a
state of opening my windows showing _a_ texture, but it'sall
black (except for the red border I allowed just to see if this codeis
doing anything at all). The closest I got was using about 4 cameras(a
Main camera, a Depth FBO camera, then 2 separate cameras for the 2final
screen-aligned quads), which would render my geometry on screenbut
nothing into the Depth or Color buffer textures..
Initialization stuff up here, nothing to do with OpenSceneGraph ...there's

Re: [osg-users] OpenSceneGraph Newbie: PErformance question
Ah, seems you're right.. I just tweaked it to load an oBJ I've been using for testing (company logo graphic) and now I'm up at 200fps in each of my 2 viewers, much better. Can I get a quick run-down on what exactly kicks it off the "fast path"? Or is this documented on the Wiki somewhere? Chris Hanson September 10, 2012 11:26 PM Yes. Virtually everything about that geometry will kick you off the fast path. Unless your ultimate application purpose involves rendering teapots, you need to try using a better example model. cow.osg or cessna.osg I think are better samples. -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Training • Consulting • Contracting3D • Scene Graphs (Open Scene Graph/OSG) • OpenGL 2 • OpenGL 3 • OpenGL 4 • GLSL • OpenGL ES 1 • OpenGL ES 2 • OpenCL Digital Imaging • GIS • GPS • Telemetry • Cryptography • Digital Audio • LIDAR • Kinect • Embedded • Mobile • iPhone/iPad/iOS • Android ___osg-users mailing listosg-users@lists.openscenegraph.orghttp://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org Randall Hand September 10, 2012 11:04 PM hrm..

I didn't actually see the vertices or polygons in the OSG file above, so I can't say for sure. -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Training • Consulting • Contracting 3D • Scene Graphs (Open Scene Graph/OSG) • OpenGL 2 • OpenGL 3 • OpenGL 4 • GLSL • OpenGL ES 1 • OpenGL ES 2 • OpenCL Digital Imaging • GIS • GPS • Telemetry • Cryptography • Digital Audio • LIDAR • Kinect • Embedded • Mobile • iPhone/iPad/iOS • Android ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
