Hello. Currently I am developing a volume rendering application with 4 widgets. In my biggest QGLWidget I show the volume, and in the other 3 widgets I want to show the sagital, transversal and coronal planes of that volume, and to do that obviously I need to share my 3D texture, but I have not be able to share it yet .

If anyone can shed some light in this overwhelming task!...

PS: Later I will post what I've done... now I do not have the source code at hand .
