If you want something to look right... build it!

The Grand Budapest Hotel proves that you don't need to rely on CGI to create a fantastic - or fantastical - look

Depth sensing cameras could revolutionise CGI

Published in Technology & Computing

The Z List: One of the great technological leaps forward that failed to really catch on the first time round was the 3D camera - a unit that could automatically capture the z-axis (the "depth axis) of a scene to create depth map information. Perhaps it’s time for the industry to look at them again.

Motion tracking - from obvious to subtle

Published in Post & VFX

Motion tracking is simple to understand, and not so simple to do. And, like a lot of VFX techniques these days, it's getting so good that you don't always know that you're looking at it

Pixar's new animation system allows animators to visualise their characters with all the important detail visible. Like hair!

Alex Roman: Transcendent CGI filmmaking

Published in Production

As a writer, it's not often that I'm lost for words. But that's what happens when I try to describe Alex Roman's CGI film, The Third & the Seventh.

Is CGI actually making films less convincing?

Holograms: Will we ever need them?

Published in Studio & Broadcast

Holographic TV: I have to declare a bias here. The Princess Leia hologram scenes in Star Wars convinced me that we will never need holographic TV. This is nothing to do with the fact that video holograms are always depicted as being fuzzy and unstable (presumably to stop them looking real, in which case you couldn't tell they were holograms). No, my issue with them is that while real life may be 3D in the sense that you can walk around it, drama isn't.

What do I mean by this?

Holograms in the cinema

Well, imagine being in a cinema watching a holographic film. If you're sitting in the centre of the auditorium, about half way up, then it's all well and good. But if you've arrived late and you're sitting at the side, then you'll have a bad time, because none of the actors will ever look at you, unless they're making transitory, sideways glances.

That's the problem in essence. Everybody gets a different view. It's not film making: it's moving sculpture.

All of which is a scarcely relevant introduction to a news item this week about a breakthrough from the International Society for Optics and Photonics, who have managed to merge the disciplines of hologram-making and computer generated images.

It takes longer with a computer

Until now, making holograms from computer images has either been impossible or has taken far too long to be of any practical use because of the rendering times. You can only make computer holograms if you calculate an extremely large number of viewpoints for every point on the holographic object's surface - a recipe for waiting a long time for something to happen.

But now, they've found a way to use more CGI-like techniques. Instead of calculating the result at ever conceivable point, they use polygons instead, massively reducing the calculation times.

The society claims to be able to produce photorealistic holograms in reasonable timescales, and if I'm wrong about the unsuitability of Holograms for film making, then this could be the breakthrough that everyone except me has been waiting for.

The greatest CGI is not in a Sci-Fi film but a costume drama

Published in Post & VFX

Baz Lurhmann's The Great Gatsby is built not around expensive sets but probably some of the best CGI ever seen (well, we should probably say "apart from Gravity"  - which, although it's in a CGI league of it's own, is not exactly a historical costume drama)
