Modify iPhone SDK sample application

Modify apples iPhone SDK sample application GLGravity (which shows a teapot controlled by the accelerometer) in the following way: (a) Load a 3DS or Blender object from a file (in the sample app, the model is hardcoded)? (b) Add texture display to the object shown (the texture must be loaded from the object file) (c) Modify the app to show 2 overlapping background bitmaps in the background (behind the object) with alpha channel taken into consideration (both bitmaps must be the same size of the screen, one above the other, with transparent areas which let the the lower bitmap see through) (d) The top background bitmap must be animated to slowly rotate. It will be slightly larger than the screen so no empty areas are shown when the bitmap is rotated. This is a project that can be done in a couple of hours if you have access to the iPhone SDK and some experience with OpenGL. You only need to change the existing sample application. ## Deliverables - if any 3rd party code is used, it must be included in an extra folder within the project and its use need to be approved by me before it can be used - the loader code can not result in long delays for processing (the application must start? immediately) - all changes in the in the sample project source code must be marked with remarks in english and the initials of the programmer to make finding these places easy - I will provide sample files (2 bitmap files for the background, 1 3d object file) which the application needs to work with to be accepted - I will provide one screenshot showing how the application should display the given elements; the final application must be able to reproduce this sample screen - The XCode project must be compile without warnings and must be runable on the iPhone/iPod touch - The XCode project msut include the complete source code for everything (no libraries without source) - The following code may be usable for this (though I have not checked it):? [login to view URL] - It would be acceptable to write a converter program which converts the 3D object into a c file which can be compiled into the sample project instead of the "teapot.h" file; however, even it that case, the object must be shown textured. If this approach is taken, we have to agree on the language used for such a converter.
