Re: [osg-users] osg camera location

Hi Ricky, I'm not sure how to answer your question because I'm not sure what your actually asking as you mixed various different concepts up. The osgGA camera manipulators automatically center on scenes that are loaded by taking the center and radius of the bounding sphere of the loaded model.

[osg-users] [forum] Is there a fast vertices filling algorithm ?

Hi All, I'm working on a sw that needs to fill up some 300k of vertices into an osg model, and it needs to do it AFAP. Currently I'm using push_back - which should have been named 'drawback'. What can I do ? :? Thank you! Cheers, Nir -- Read this topic online here:

Re: [osg-users] [forum] Is there a fast vertices filling algorithm ?

Hi Nir, All the osg::Array subclasses use std::vector so you have all the usual std::vector methods for allocating space - resize and reserve, and assigning vectors. Robert. On Sun, Jul 11, 2010 at 12:25 PM, Nir Putter nirput...@walla.com wrote: Hi All, I'm working on a sw that needs to fill

Re: [osg-users] osgVolume volume rendering ?

Hi, I have a working osgVolume used in my program - I use it as a preliminary visualization. Since it has only 1D transfer function support, and does not combine with polygonal models, in later stage I replace it with isosurface+polygonal model. My version is basically a simplified osgVolume

Hi Michele, In osgAnimation a Bone inherit from MatrixTransform so a way to do it run a visitor that will check the matrix of your Bone. Another way could be to add a Custom callback to your bone that will do something on your Bone. I have not tried yet but I guess both way should work. Cheers,
