Hi,
I have been studying the source code for the Fortran bindings and the
aribtrary storage facility and my conclusion is:
- The bindings will benefit internally because we do no longer have to
create a transposed array in the C fashion.
- I can create a binding for the most flexible functions (plfcont and
plfshade(s) so that a user can supply his/her own data structure.
It will take some interface juggling in Fortran 90/95, as that is
more strict than FORTRAN 77. (Some technical details are involved
here)
I first thought it would be a flexibility that would "never" be used
in practice (2D arrays being the most common form of storing such data
in Fortran), but consider this:
We do not have to store a complete set of data! Instead we could also
use the retrieval function to get the value of a function - something
along these lines:
real(PLFLT) function f(i, j, params )
integer :: i, j
real(PLFLT) :: params
real(PLFLT) :: x, y
... compute x and y from i and j and params
f = x**2 + y**2
end function f
or to transform the data:
real(PLFLT) function logf(i, j, data )
integer :: i, j
type(userdata) :: data
logf = log(data%value(i,j))
end function logf
(I am not quite sure how to transfer the array dimensions yet - hence
the impromptu derived type)
Regards,
Arjen
