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.

[osg-users] Modify texture data on runtime
Hello fine gentlemen, I'm trying to render a dynamic texture, whose pixels are manually modified during runtime. I'm assigning the texture like this: osg::Texture2D* texture = new osg::Texture2D(img); texture->setDataVariance(osg::Object::DYNAMIC); osg::StateSet* state = geom->getOrCreateStateSet(); state->setTextureAttributeAndModes(0, texture, osg::StateAttribute::ON); where 'geom' is my geometry object, and 'img' is an osg::Image I've allocated manually, and which I plan to modify during runtime. The problem I'm having is that my 'geom' object is using the initial Image (the image as it was when assigning the TextureAttribute). Even if I modify the pixels in the Image, using img->data(), the rendered texture is not updated. What am I doing wrong? Is there a more optimal way to manually access the pixels of the rendered texture at runtime?

[osg-users] flickerring and aliasing effects
Hi, i have made a mini airport with a runway in blender and exported it to use with an osg application i I placed the airport model just some unit above the terrain but when i fly in the scene i have a very noticeable flickering effect especially at high altitude + some very horrible aliasing effect in the airport model is there any osg settings can i turn on to fix these two problems even with loosing some fps ? thanks and good day -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=35168#35168 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
