Request an update~~！Please~！

heres a paper I found that talks about the math of anamorphosis:

http://www.physics.uoguelph.ca/phyjlh/morph/Anamorph.pdf

heres the basics about the format:

http://en.wikipedia.org/wiki/Anamorphic

Heres some brochures from Panavision – you can see the squared off frontal area for the lens.

heres some history of them:

Hope something here helps you! I wish I could help with the math and coding but sadly I am not nearly as versed and capable as you are on the subject!

I will look thru your links and see what I can offer in terms of what would be cool…

Anamorphic blurs are a bit strange in that they scale at distance ( further from focus gets squeezed ) and the bokeh is different… they have longer horizontal view but same vertical view and shallower depth of field — I think they are also paired with a prime lens… so its really lens on lens on lens!

btw – heres a better link for the research paper I found… dunno if its helpful but it has some math on anamorphic lenses as well as discussion of their optical aberrations…

it would be so awesome to see something like this actually working in Cycles!! thank you for replying!!!

Regarding Anamorphic lens:
I would like to (help) implement this system in Cycles:

* http://www.graphics.stanford.edu/papers/camera/

I don’t know how hard would that be, so I can’t promise anything. But I think it may be able to do anamorphic lens as well. Can you take a look at this material to see if it would fit what is needed for anamorphic lens?

Perhaps, if you don’t need real dof, bokeh, … you can make a patch based on the fisheye panoramas. All you need is the function to map from UV to direction.
And I will need to read on anamorphic lens, but if the principal is the same as with fisheye (and all the rays come from the camera nodal point/focus) you could render in blender and warp/stitch with an external software (e.g. Hugin)

I would love an anamorphic lens distortion and aberration system and if Cycles if capable of real world light interaction – I wonder what it would take to get a setting for anamorphic lenses as well?

Some of the most highly regarded films were shot with anamorphic lenses and that was part of their secret sauce for the look of the film… high end anamorphics are extremely expensive to even rent – and some places don’t even sell them ( Panavision ) — compositing elements into anamorphic shot footage is something Im trying to do – and would love a Blender based solution – and Im sure there must be others who would want this…. Zeiss is coming out with a new series of anamorphics and theres been a bit of a resurgence in interest in shooting with these lenses.

Ok just thought Id drop this off in case theres someone out there who is also interested!

I asked on another site and I thought I would ask here too since you are the expert on this stuff…

I am shooting a short film with anamorphic lens! and i want to be able to composite 3d elements and effects into the plate shots using Blender / Cycles etc.

What would I need to do – to simulate anamorphic lens? bokeh? blur? etc? is it possible with the built it cycles tools? or would you recommend splitting the scene up into foreground background items and doing something like a displacement node for distance and blur squeeze? ( anamorphic lenses squeeze more at a distance… you probably already know this. )

Can you give any advice?

cheers!
