Anaglyph Specs

Every now and then you get thrown something that’s pretty cool to work on. I’d always thought stereographics were great, from the classic comic books that came with 3D glasses, to the early experiments in cinema. (Some of which was utter bollocks.)
So setting about building a 3D intro was a bit of a challenge. Initially I thought it was just a case of splitting the colour channels and that would be the end of it. However it soon became apparent, as most things in life do, that there was an element of skill and craft involved. Saying that, if everything was easy, where would the fun be.

The 3D glasses were made in after effects, using 2D shapes, build in a 3D environment. Using lights and shadows left some strange artifacts that needed to be modified before the final renders.

To create a strong anaglyph effect, the 3D glasses where rendered twice. The camera captured each render with a slightly different view point, replicating the left and right eye. These renders would then be combined and using channel mixer to split the colours, would create the final image.

This image shows the two rendered movies stacked and colour split using the channel mixer preset. Once overlaid they combine to create the anaglyph image. The amount of offset dictated the amount they shift in 3D space. To create more depth, the red / cyan offset is reversed for the background and the mid point has a neutral offset.

And these were the glasses I used for testing.
