Rfm: Fisheye Lens Shader

[tomc]

hi,

i ll do some research for out next project....
renderman for maya seens very good for our needs... except camera lens...
i ll need render a camera with fisheye lens
i have found a shader on the web....
http://terpsichore.stsci.edu/~summers/viz/fisheye/
it works good but the shader use raytracing
and thats means i can not get a alpha channel..... thats my problem....
any ideas how can get fisheye render with alphachannel ?

cheers,

the "rmanEnvRenderPass"render-pass of RfM renders 6 fine pictures of the enviroment... and "txmake" stich the imges to a "cube enviroment" picture... if txmake can stich the picture to a "fisheye enviroment" picture.... this would be perfect ! a fast fisheyeenv.-rendenring without needs of raytracing....
anyway the "-envlatl" option of txmake seen not working...

Well yes, but youd be calculating alot extra in vain, and the samples wold be a bit incoherent. But thing is preserver can reder nowadays a curved clipper s it could be possible to actually render directly the fish eye

But yes theres alot of progs out there that can turn a vertical cross into a fish eye

render directly the fish eye would be the best... im watching out for release 2.0

Well i don't think rfm for maya will get the functionality simply because they want to sell pro server for people with extended needs.
