Re: [osg-users] [ANN] MS Kinect - official drivers available
Current Kinect drivers (libfreenect, SensorKinect) already expose the 640x480 depth map and the NITE skeleton tracker probably already uses this. The news about increased resolution is solely related to the data as used by Xbox games which are currently limited to 320x240 resolution, as far as I know. Christian.

I heard news that the resolution of Kinect might be increased to 640x480 by firmware update (some additional compression on the USB link). Then this might be feasible.

Re: [osg-users] [ANN] MS Kinect - official drivers available
I've used the OpenNI framework and it doesn't work with the Kinect out of the box. The reason for that is that OpenNI targets PrimeSense's reference platform, not the Kinect, which is a product based on it and not actually produced by PrimeSence, as far as I know. However, some people have already modified the drivers to recognise the Kinect and use it with OpenNI [1]. To use it, first install that modified driver and then the normal OpenNI. The sample applications of OpenNI then recognise the Kinect. PrimeSense also distribute NITE, which is a closed source package that extends OpenNI with a pretty good skeleton tracker and a few other nice things. Christian.

[osg-users] [osgPPU] Ploblems with anaglyph stereo rendering
Dear all, I have been trying to apply osgPPU for stereo rendering and that appeared to work. However, when I took a closer look at the anaglyph rendering of the osgppu_dof example (run it with --stereo), I noticed that it does not work as expected (running the osgPPU pipeline on both views, then applying anaglyph), even though it kind of looks plausible. What happens instead is that the left render pass executes the pipeline on a red cow (osg uses colormasks for rendering the anaglyph). In the second pass, osg additionally renders the cyan parts into the same input texture and runs the right pipeline pass based on it. For the second frame, the input texture is still the previous anaglyph with updated red-channel. Both passes are using the correct depth buffer for their view. This problem is bugging me, as the same stereo pipeline works correctly with quad-buffered stereo. I think the fix would be to render both left and right views in full colour and then combine them in a shader to compute the final anaglyph image. This way it would also be possible to support other types of anaglyph, such as red-blue, green-magenta [1] or blue-amber [2], which may not be easily implemented using RGB colour masks. My question is: would this be a useful modification of osg? What do other people think? Thanks, Christian.

Re: [osg-users] [osgPPU] Problems with resizing
Hey Mick,
That looks useful thanks a lot!
To be honest, I was a bit surprised that textures could be resized by
simply calling setTextureSize(…). I was wondering why one doesn’t have
to reallocate them with the new size.
Anyway, thanks :)
Christian.

I'm not sure if this addresses your problem exactly (I'm not very familiar
with osgPPU):
If I need to adapt my viewport and to resize my RTT-textures I use something
like this:
Code:
_cam-setCullCallback( new fboAttachmentCullCB( this ) );
void fboAttachmentCullCB::operator()(osg::Node* node, osg::NodeVisitor* nv)
{
osg::Camera* fboCam = dynamic_castosg::Camera*( node );
osgUtil::CullVisitor* cv = dynamic_castosgUtil::CullVisitor*(nv);
if ( fboCam cv)
{
cv-getCurrentRenderBin()-getStage()-setFrameBufferObject(NULL); //
reset frame buffer object - see RenderStage::runCameraSetUp for details, the
fbo has to be created again
cv-getCurrentRenderBin()-getStage()-setCameraRequiresSetUp( true );
// we have to ensure that the runCameraSetUp will be entered!
}
traverse(node,nv);
}

Re: [osg-users] [osgPPU] Problems with resizing
Hi there,
I have been trying to extend the osgppu_viewer to allow resizing of the viewer
window, similarly to the discussion at
http://forum.openscenegraph.org/viewtopic.php?t=3693. However, I'm not making
any progress and already wasted way too much time on this.
The problem is that I cannot set the camera's viewport without everything going
funny. This following code is called by a custom
osg::GraphicsContext::ResizedCallback on every resize:
Code:
void Viewer::resize(const int width, const int height)
{
osgDB::writeObjectFile(*_processor, pre-resize.ppu);
// resize textures
if(_colorTexture.valid()) _colorTexture-setTextureSize(width, height);
if(_depthTexture.valid()) _depthTexture-setTextureSize(width, height);
// new viewport
Viewport* vp = new Viewport(0, 0, width, height);
// update camera
Camera* camera = getCamera();
double fovy, aspect, znear, zfar;
camera-getProjectionMatrixAsPerspective(fovy, aspect, znear, zfar);
camera-setViewport(vp); // ???
camera-setProjectionMatrixAsPerspective(fovy, width / (double)height, znear,
zfar);
// force processing pipeline to update
_processor-onViewportChange();
_processor-dirtyUnitSubgraph();
_unitOut-setViewport(vp);
// update all units' viewports etc.
NodeVisitor nv(NodeVisitor::TRAVERSE_ALL_CHILDREN);
_processor-accept(nv);
osgDB::writeObjectFile(*_processor, post-resize.ppu);
}
For testing, I'm using the depth-of-field pipeline from osgpp_dof on cow.osg.
The viewports of all units appear to be resized correctly, as can be verified
by comparing the before/after saved .ppu-files. However, the displayed results
are not correct.
When I comment out the line marked with ???, I get the pipeline to fill the
window (with correct aspect ratio), but only in the original resolution (here:
640x480; without line.jpg attachment):
[Image: http://img210.imageshack.us/img210/6479/withoutline.th.jpg ]
(http://img210.imageshack.us/i/withoutline.jpg/)
And when I set the camera's viewport, the viewer only shows the bottom-left
640x480 pixels of _unitOut's texture (with line.jpg attachment):
[Image: http://img13.imageshack.us/img13/1299/withline.th.jpg ]
(http://img13.imageshack.us/i/withline.jpg/)
Any help is appreciated :)
Thanks,
Christian.
