I’m working on a program that lets the user load a .obj file, manipulate it and then save it. I am working in Xcode on OS X and building the windowing side of things in GLUT so that I can use C/C++ rather than objective-c and cocoa interfacing.
Right now, the name and path to the .obj load and save files are hardcoded into the program, but I want to make it possible for the user to specify these.
Can anyone suggest a way I can do this given that I am using GLUT, etc.?
