Re: New 3D crosseye panos (also posted on panoguide)
- Hi Roger, Thanks for your insights I very appreciate.
The lateral shift in NN3 was 3 cm so I have a 6 cm lens speration.
As I said, I need to improve my 3D retouch.
Except for stitching all the process/retouch I done was in software
that I wrote myself which was designed for 2d but I'll implement some
3d brush and clone tool and selection tools mean to morph
selection/intervention from each pixel from left-eye to right-eye is a
corespponding map I think of from some time or maybe a simple crosseye
preview/magnifier will help.
It can be done almost perfectly, the moving objects can be cloned and
placed as flat but in a diferent plane in 3d space the offest can be
also "clonned" from nearby objects, mean to have the same offset from
flat-left to flat-right as the genuine 3d objects. This will work for
small/distants objects. I've done this before at conversion of the
regular photos in 3d ones using sparated layers and then placed in 3d
space by a particular offset and x,y position.
Smartblend could be an option but I'm afraid that it can be smart
enough to compensate the parallax beetween and such to reduce the 3d
effect, so I'll not use for a while.
