Wanna know how it's done?
On the crblog they asked Diesel and this was the response:
“The visuals are projected through a series of ‘foils’ into mid air, so you see the images in mid-air. The models can then interact with them and walk through them. We used plastic foils placed at 45 degree angles so that the projected light from the ceiling goes onto a foil, is reflected on to another and then into the air.
We worked it so it had a real catwalk feel and so that you could view it from both sides: you can see the models, the holograms and the public from both sides. It’s never been used this way before as the technology has just been used in the corporate world before, for sales presentations, and the visuals have always just been viewed from one side. So we set up two rigs instead.
The animations were done with standard CGI animation software but were made for a 15m by 2.5m screen. It’s all rendered in HD, too, so was quite demanding as it’s 30 frames per second. We worked on the whole thing, from storyboard through to the final render in just two and a half months. Bringing together Dvein and Vizoo gave us this unique, truly holographic, 3D motion graphic experience.”
If anyone has more in depth info i would love to know.
