Thank you Sean for letting us know that Qt3d runs on the IMX6 and Tegra K1
platform. Your work is invaluable. Qt3d works well on desktop so I have
faith that it will run on many other embedded platforms. I will have uses
that can will take advantage of these two platforms.

The Raspberry Pi is a powerful platform that will use Qt3d eventually and
properly.  So many developers, like me, are on shoestring budgets and I
want to reach them as the world needs lower priced platforms.

One of your developers has a Raspberry Pi. His name is James Turner. I
spoke with him at Sigraph and he showed an enthusiasm for getting it up and
running on the Raspberry Pi.
