[Rtk-users] error on build rtk in visual studio 2012 when rtk use cuda

[Cyril Mory]

Hi Safdary,

Just to be sure: have you tried reconstructing in a larger volume 
(something really huge), just to make sure you are not trying to 
reconstruct some portion of space where, indeed, there is nothing ?
You can try that easily, just replace your spacing, dimension and origin 
with
--spacing 16,16,16 --dimension 256,256,256 --origin -2040,-2040,-2040
in your rtkfdk command line.
