[Rtk-users] Issue with Cuda filter

[Yu Zhang]

Hi Simon,

May I ask you a question about how to use the following filters:
CudaForwardProjectionImageFilter is similar to
JosephForwardProjectionImageFilter

I was able to get satisfied results using
JosephForwardProjectionImageFilter,
However, when I switch to CudaForwardProjectionImageFilter, the output is
all zero.
I run the test of those filters, which turns out to be successful. But I am
not aware of
any config parameters to check whether CUDA is actually working or not.
The version I am using is rtk 1.3.0, but it is the same as previous version
from github.

Best regards,
Yu Zhang
