[M2] Forward Projector
Iterative algorithms need a reasonably fast Forward Projector.
AC:
- Readable cuda or opencl code
- Joseph interpolation scheme, with tunable ray oversampling
- Results close to Astra or HST
Optional:
- Reproduce results or HST if the same interpolation scheme is used.
- Implement another, more straightforward interpolation scheme (for a faster and more readable code)
Next steps:
- Make the projector(s) available as an OpenCL processing in silx
