Hey Mark : Brother's in the house , eh ? Uh oh . Explains why you didn't actually read my mail before replying to it <grin> . No problem, I'll take just about any kind of reply I can get these days .
Yes , I do remember those images very well , and considering the lack of info on RS HDRI usage , they are just as relevant today as they were then , to many RS users anyway . I have Timo's plugin and in case you missed it , here's the link to outputting RS HDRI . http://www.3ddart.org/index.php?name=PNphpBB2&file=viewtopic&t=611 What you're doing sounds very interesting , and now you can out- put those images in HDRI . My point was using an HDRI of a Cathedral interior (only as an example) to do details on things like the golden Challice on an Altar . IE : Do the render of the Cath interior , output the HDRI of that interior (using the Chrome Sphere method) , then use that resulting image in Timo's plugin (to render the Challice) . It's no big idea , just an obvious workflow . Anyway , looking forward to your resulting panorama's . I still have that java 360 panorama program somewhere if you'd like it . A small blind spot at top too , I think , but zooms and the Real3D project already has the camera set up perfectly (no RSV5 project for it yet , however) .
