Maybe the solution I'm looking to is to modify the dx importer in suche a way that, when it reads from a binary file a double array it stores it in memory as a float array?
This is what you want to do. It makes more sense to handle it this way and should be pretty easy to do. To clarify your statement, I think what you want to say is: Within the Import module when positions are read as anything other than float, they should be cast to float. The positions component is defined on page 19 of the User's Guide to be float[n].
