[liu ming]

Hi,

I am learning  the osg example "osgcomputeshaders",I have a problem that how can I save the image(the result of a computation) from shaders to my folder ? I use the code :

     
Code:
   while(!viewer.done())
	{
	
		viewer.frame();
	
		osgDB::writeImageFile(*(tex2D->getImage(0)),"abc.jpg");
	}



but it do not work,Could somebody give some suggestions ?

Thank you!

Cheers,
liu
