Hi there,

does someone know how I can setup a 360 degree panoramic camera ?
Would be also great to know if that is possible with a vray physical camera ?

thank you so much

Are you trying to create a 3d panorama of a static scene? If so, why not use one camera (you may have to change the pivot point) and animate a "Y" rotation through the timeline so that frame 1 is set to 0 and frame 15 or so is set to "360". If not, I can't think of any other way to achieve the result.

You can render cross enwironment from 6 cameras with 90 degree FOV and than convert cross to latlong(in Nuke for example).

It's easier to get it use JS_panoramic shader for mentalray!



Check here : JS_panoramic (http://www.andrewhazelden.com/blog/2011/01/js_fisheye-and-js_panoramic-compiled-for-maya-2011-x64-on-mac-os-x/)

if you want to use it for a qtvr i recommend using the dr_panorama lens shader http://duikerresearch.com
I founf the js_panorama didnt show details directly above or below the camera and got a perfect wrap with the dr.

Hi.

For rendering spherical (equirectangular) 360x180 degree panoramic images in mental ray I prefer the latlong_lens shader (http://www.andrewhazelden.com/files/2011/January/latlong_lens_shader_for_Windows_x64.zip) over the JS_panoramic shader due to the way the zenith and nadir points are handled. An alternate shader is the cubemap_lens shader (http://www.andrewhazelden.com/files/2011/January/cubemap_lens_shader_for_Windows_x64.zip) that makes it easy to render out cubic environment maps.

You can read about the Windows x64 build of the shaders here (http://www.andrewhazelden.com/blog/2011/01/latlong_lens-and-cubemap_lens-mental-ray-shaders-compiled-for-maya-2011-x64-on-windows/) or about Ralf Habel's original 32-bit shader here (http://www.vi-motion.de/latlong_Tutorial/). I also compiled a Mac (http://www.andrewhazelden.com/blog/2010/11/latlong-lens-shader-compiled-for-mental-ray-for-maya-2011-on-mac-os-x/) and Linux (http://www.andrewhazelden.com/blog/2011/04/more-mental-ray-shaders-for-linux-64-bit/) version of the shaders.

I rendered a short animated clip with the latlong_lens shader:

Is that LatLong lens shader less distortion than JS_panoramic? :shrug:

Yes.

The LatLong lens shader has less distortion than the JS_panoramic shader does.

I would recommend the dr_panorama shader as well (link above). I've used it a lot in production to render out HDRI images of my scenes for reflections as well as animated HDRIs. It works perfectly without any distortion. The only issue was on OSX I was required to render using Raytracing instead of the default Scanline.
