I'm trying to familiarize myself with data storage
using Cocoa.
Having entered the Cocoa game relatively late, I'm
curious about CoreData's potential for maintaining
relationships between models and saving data and
whether the purpose I have in mind is a suitable
application.
I have large 3D (Wavefront) .obj models that I need to
load (parse) and store as part of a document created
in my application along with other data such as
lights, vertex shader etc.
CoreData supports only limited file (xml, sql and
binary) and data types, so how would I make use of it
to maintain relationships between models that use data
types such as arrays and structs etc?
For instance: would it be better to have a number of
files stored, and have the application document
reference the vertex data, shaders, blah blah as
separate files rather than trying to squeeze them into
1 file? As this approach would seem to facilitate the
editing of each file type, as well as scalability.
At this early stage the application at its simplest is
a 3D visualizer, i.e load and display a 3D model.
I'm new at this, so if I'm way off I apologise, but I
would really appreciate a bit of conceptual help in
visualizing an application that supports a wide
variety of data types, but can take advantage of
CoreData.
I'm continuing to look at the documentation and posts
relating to saving application data, but the forest is
large and dense at the moment, so sorry if this has
been answered elsewhere.
Many thanks.
