pannini/vedutismo projection for wide angles/panoramas

[piotrus3333]

any chance of getting that type of camera in VRay? It's perfect for archviz.

I use this type of projection (in Hugin) a lot when photographing very wide angle views too. It stops the horizontal stretching you see at the left/right sides of rectilinear wide angle images - no more fat people!

That may actually be interesting for me doing product shots, too.

I had this "fat" issue when photographing a collection of similarish products where the outer ones tend to get fatter.

not a bad idea.

but you can always render out a 360 image. and do it in hugin, ptgui, krpano etc...

shure I can, but still not the same as having camera with that projection. and there is also a hassle of matching to pannini backplate.
I don't mind having incorect representation of it in the viewport, RT would be enough to see what the frame looks like.

Very good idea. +1. The only thing that sucks now, is that Chaosgroup no longer uses his own camera but one of 3dsmax, which means, we'll have to wait for years, if not forever.

[Art48]

Is CG bound by contract to develop/use the 3ds max one now? Or do they still have the ability to program their own?

oh, max's 2016 phys camera, I forgot about that, I'm still on 2015 and definitely not planing on switching.
so usual cam overrides from VRay settings don't work anymore???

Yes they still do. But would be great to have this in viewport too ^^.

I don't want to ask for too much.
and I'm not sure how easy it is to implement it even with the most basic functionality.

I agree, this sort of camera correction would be quite useful when working in tight architectural spaces. Some implementation is already there via " Cylindrical(Point)" Camera. I wander if it'd be possible for Chaos Group programmers to just add a slider to control affine translation between Physical camera plane and Cylindrical one ( like: 0= phisical camera, 1=cylindrical camera, 0.5= projection on an affine curve half way between. That'd be good enough for most of people I guess?

But the cylindrical distorts the horizontals?

[3LP]

Yep +1 for me

[Pixelab]

+1 That's a must have for Architectural photgraphy

But indeed, IDK if VrayCamera is still under developement

check out this lens file. I would say 10-12mm lens.
