I've implemented something similar to this before. Not specifically for face morphing butmorphing between two meshes. As long as your meshes have the same number of verts (I forced this condition by adding degenerate verts) you just need to set up a blend linear between the verts you want to morph

HI Ross, OSG 2.x and osgViewer have much better support for handling of contextID when sharing contexts and opening and closing contexts, you shouldn't need to manually manage contextID's when working with osgViewer so perhaps this is the route of the problem. Robert. On Jan 3, 2008 6:57 PM, Ros

Is your image returning a valid pointer? If not, then either the TIFF file is corrupt, or your application cannot find the necessary plugin (osgdb_tiff.dll or osgdb_tiffd.dll) to read the format. An easy way to test is to rewrite your code slightly. osg::ref_ptr image = osgDB::readImageFile(

I think you need to set your (*ponto_itr) to NULL or remove it from the vector after you have done the remove child, other wise the pointer still has the address of the child you previously removed so you for loop above (ponto_limp) will never do any thing __

Hello and happy new year to everyone! I just want to know if it would be possible to retrieve the old osgProducer SCENE_STATS in osgViewer. I know actually we dont have code for this functionality, so what would be the first steps (examples, guidelines...) to get the same data using osgViewer?

Re: [osg-users] Selective lighting in OSG

Re: [osg-users] Selective lighting in OSG

Hi Pavlos, Using shaders is certainly more flexible, but it does bring its own complexities. FYI, the complexities in handling standard OpenGL lighting with more than the max supported comes down to the way that the OSG handles that fact that lights are positional state, and positional state has

Hi, Gordon. I've looked up the doxygen documentation, and the second argument of removeChild is numChildrenToRemove, which I thought stood for 'number of children to remove'. If so, wouldn't I want 1 child to be removed? Isn't my index correct? Thanks,

Re: [osg-users] Error: 'Debug Assertion Failure!'

Hi Renan, Did you clean your ponto vector after removing the child of the parent?. If you don't do that, you find that ponto has (for example) one element which value is NULL. The problem is that you don't use ref_ptr to save elements inside the vector and OSG does. So when you remove the children

The assertion is doing its job and telling you the issue a bad index ( also might be good to tell us which line of code is doing this, I'm assuming which one here ;) ) Will you always have 2 or more children ? as your code is removing child number 2 every time(indices are zero based), so if you
