Skype has said it's working on 3D video calls, but won't introduce the feature until the camera technology catches up.
The firm's corporate vice-president, Mark Gillett, said it would be difficult to bring 3D video calls out of Skype's labs until cameras could capture 3D more easily.
"We've seen a lot of progress in screens and a lot of people now buy TVs and computer monitors that are capable of delivering a 3D image," he told the BBC.
"But the capture devices are not yet there. As we work with that kind of technology you have to add multiple cameras to your computer, precisely calibrate them and point them at the right angle."
Gillett confirmed that Skype had the technology "in the lab".
"We know how to make it work and we're looking at the ecosystem of devices and their capability to support it in order to make a decision when we might think about bringing something like that to market," he said.
"You'll see much more penetration of 3D on TVs, on computers and ultimately in smartphones, probably, ahead of seeing it for sending a video call," admitted Gillett.
